Description

updates from SciPy 2017 and the DISC presentations in Australia

A

A

Stuff and interests il-song.

A

B

Vacation its innocence.

C

D

C

So sorry reminding me, although it had been on my calendar, that next Monday is the total website I'm just throwing that out. Look at ten o'clock.

C

But I think look it's a once-in-a-lifetime event. Yeah and technically we were not enough. You know super path to that yeah. It should be.

E

C

D

D

So you need a view out to the east. Pardon me: we need a view mostly to the east I guess. If it's ten o'clock, the song will be fairly light.

D

F

We just use that camera to look evidence. Yeah point the point: asylum, okay,.

A

C

So I wonder like we just go from here or go to some place.

C

You know eight and.

C

Buggies yeah, so there it is unobstructed views. Oh, let's do that.

C

Well, let's not let these opportunities pass.

C

So we can coordinate some mundane care I'm.

G

Sorry that wasn't.

A

A

In fact, the last location kokuboro who is working on a 1d MT version- and she gave a talk at this love. Then there were a lot of questions around how she was doing the inversion. So we need another model like where, after her talk and I got that set up- and she has since like emailed us back and it's getting version results alright. So that's three and there's also just in general, a lot of interest in public there's. A lot of people.

D

Using mod en right.

A

Now, solely for all the Auslan stuff, a lot of the work we've done in Monaghan kind of language.

D

A

That's scary efforts.

A

Yeah and it's pretty, that seems to be the as I've been chatting people Molly I'm seems to be pretty common I'm.

D

The main frequency of both crazy and just renting yeah finite difference.

A

Yeah but there's definitely interest in people jumping into sympathy bits as well as processing. So there's a lot of people again using gigahertz code, but it's sort of black box and so do people actually wanna go didn't be something customers.

A

So that's something that's worth keeping on their radar. I know we pushed on that old recently and that's potentially ok. They don't think it's about things. It's really about sit as long as we don't let them all off yeah.

A

So there's a few people there that potentially follow up with and get sort of like what I was asking for was perhaps like a sketch of what they want like how they might work yeah yeah, because they were quick member who said you know: I'm, not necessarily a programmer I'm, not gonna, be able to jump in and help you architect this, but I can tell you like what I need to do.

D

A

In that's good, so if we get some inputs or not.

F

Yeah, we certainly need someone that will want it. We got both I'm America's I. Don't have time to take on this. You don't have fun yet, unless it's really related to your research, yeah.

A

If Jarrod starts, I mean if we get some people that start pushing on it, the guy can help sort of organize some.

D

E

I can assure you.

D

A

C

Particularly I just get a sense, though you overall continually gaining traction the empty tutorials, a really really good, and we didn't get a chance to kind of explore them in huge detail.

C

But we also stopped from where we were in in East Asia, but saw an opportunity actually take them all the way through in the forward modelling discretization, for that was. That was a real good information to them. So I I.

D

Think there's nothing but.

C

I'm sort of positive stop this coming. What one thing is clear: there's there's a real opportunity: what's the disks finishes to continue this kind of material I think extend it because what you know right now, we're you know like I'm, the last two trips over Saudi and Lindsay have just just kind of nicely sort of God. To just give me no brief overview and then kind of which is good. I mean it.

C

It opens some doors, but then there's another level to actually, and that is dirty where people want there's a lot of people like okay. Just let me know how to really get something.

C

Yes, I think you know just continued development of SIF a and the tutorials, especially the tug before just you should go back to all the basic stuff that we had with in the I XE d and then the other step to and just just revamp that and then parse it out a move it piecemeal stuff, because people are just they do not know that the fundamentals are they forgotten the fundamentals and he just gets so caught up in having this 3d sophisticated algorithm that they can put in there.

C

They get something out: they're, not paying critical attention, so I think that's gonna, be a challenge for us is to not only develop these tutorial things instead paper, but also to really see how to engage people and get them going. Of course them to answer questions yeah, but.

D

A

C

That all future.

A

And there's lots opportunities to have those things published as well like the Kiki sentiment, this important.

C

Tracks for the T on the article is there some way to keep track as to how many people actually down a little bit? If there's nothing, I.

A

A

B

Think at least a different track citations. If someone.

D

B

Not sure it said it's not a wrath great article or yes,.

A

But we should still be on the track downloads, yeah.

B

A

It's like the computer sciences, charts down.

C

Have you ever heard anything I'm, sorry, something forever me any of the groups in South Asia. Remember we were trying to get them so excited about adopting with one DM to the problem and well.

B

I'm in control now we can said that another email.

B

I think I've contacted before we Korea. Yes, yes,.

A

Fair analysis.

B

And I I think nano became half of attempted student chapter is demon chapter period. I know, I, think that he was positive without.

C

B

Contacting him but I wasn't sure we could I.

D

B

A

C

That's great I mean every time you've got.

A

Something a little bit new.

C

Like you know, your took this up. I got it yeah.

A

There's a couple things to think about: there is, if you could actually sort of start like a mailing list and see if people want to be updated on, like. Oh, that's,.

D

A

Thing to do and might be a good idea just how Avenue that's a little more formal than people opt into.

A

So we think about the other good thing that I wanted to bring up was the Google Form yeah, so that I would really appreciate if everybody can sort of direct questions there. So if you get an email from somebody directly to you, if you can say please, we post this on the Google form and then click the reason for doing that and I think most people get it. Is that like this then becomes supplementary documentation yeah, because we're.

B

Dating someone you.

A

The same question right people like how do you output a file so I created in something say: okay, like.

E

I, don't need to answer this directly to you. Somebody should be able to Google this so you're, going on it's like channels, yeah like.

A

If it's, if you need to have the conversation, slot is a great place for that. But if somebody's asking you like for instructions, it should go.

A

C

Not sure I caught up so that.

A

There's no and we'll create links from the website, but there are, though there are questions now that people are asking about senpai and you can post it on this Google forum and a conversation about it, and then this is searchable. So if somebody's looking for some hey I look for magnetic stuff it up it up. You'll hit this okay. So, for example, let's see there's 26 views on how do you change the source type in the frequency domain? Iam lateral? So some.

D

A

Asked that and then 26 people have since gone and looked at that answer.

A

So it's like much more valuable.

G

Than just responding.

A

To one person is female, great 26, other people have that question and right.

C

So it's just like a frequently asked question yeah and then the thread yes. Can we just look at those so there's a poor post, yeah.

A

C

A

Here I answered some examples: follow-up question.

A

Okay, so- and this comes in them in your email, just as like page and you can configure your settings so that if you only want to see it once a week or something like that, I don't really appreciate. If everybody here would be willing to keep it up, every email that comes in you see, because then that helps distribute the workload for answering these things today.

F

Yes, I must do the champion that.

D

Sort of idioms.

F

Like 30 seconds yeah.

A

So but I think it's going to be a valuable resource, and how do people know about this right now, late, just from people with an email, Iman back and saying, go, go check this out there it's posted on since they can get help I think you should post on the Hawks economics area.

F

Because the most popular ones, we converted them into a yeah.

A

I've had something like it really does seem like. If you want to be doing something community-based like building up examples by far the most valuable community, because yeah, you need to see the workflow.

A

A

Know don't you've mentioned hunting Jake for really.

F

Good okay, yeah yeah, so we good for DC yeah, that's police, just to test the essence yeah to get some decent results and we're talking yesterday about the going towards the title inversion right then so we have conformed. Jay I, just sent it by so much more. The tablet health strategy, yeah cuz, what's Torah, it's just an interpolation after yeah, so we have it for our potential fields and now VC yeah you're interesting to see. If we can no, it's not master son to do that. Also yeah dismisses.

B

Can comb objective function handle, for instance, they've got for like a ten.

E

B

Data, yes, we generate the ten mesh and they're like yeah, we're good, like a beastly like pad pretty fast. Okay, like strep reaction. Ever so we could Pat three fast. So each match could be relatively small compared to fools. Reading that, and so each problem we're going to get a griever chittering 210 problem, 10 DC problems, for instance. Then, if I put that into a combo object, you function at it as a day domestic can can it handle like. But my model is one like that and then I have a mapping that I can't mess.

B

Look at the feed then to all problems. So I passed the global mesh like a map mulling, the global mesh, then.

D

B

At that mapping transfer that into small much so if I have that functionality that can come up check your function like it's.

A

Mapping model, and as long as each problem takes its own mapping, that.

B

Should be fine right because it's like at one point: we were thinking about the making a global problem, but at this point on you, don't really need that right so that the combo projected function is enough to handle that yeah yeah. So that's actually yeah and that's the premise simple, that we've got all the pieces. I guess then yeah combo.

A

So what we did is previously instantaneous baked in that you had one day to rest fit in one regularization. Just with waves got it, and so what the combo ejected function does is like art and says you can make up your objective function, how everyone? And so, if you have multiple regularization when I'm just back them up, you can basically just write it down and then say: my objective function is now Phi 1, plus Phi 2, and you can speak back in code and then under the pig nose.

A

Okay, but I ask for my body, which is the sum of Phi 1 and Phi 2. It notes just go evaluate this one that other it was one something where.

D

It's yesterday.

A

Is so you can sort of like assemble it and abstract it? So, the end of the day we have it be able to fit in a regularization. Quite your data, misfit de lespinasse, and then.

C

There's flexibility on each of those to add additional parameters or something waiting, yeah.

A

As long as this, each of them knows how to your value eight themselves, it's a curative. It is knowledge.

C

So did the objective function. Sorry about objective function requires that you calculate the derivative and the second oh I.

D

G

For the regularization for.

C

The regularization.

A

Yeah example: two I also think it would be great eventually, example, if that's multiple meshes for different frequencies. If so many people have talked about that, and we have.

E

A

But I actually think that we would get a decent uptick anchors. He.

E

A

Say bromine and.

E

I'm gonna have a memory mention at.

F

Neutral problems, yeah yeah, it's good.

G

C

I mean I think this is one of the things that he does not do as far as that right so I was talking to somebody who is boss.

A

C

It ran into problems just because their initiatives are really big and yeah. It's so not physically. This besides we've got such a wide range of frequencies. That.

A

Yeah, where he was working on the journey there, for instance,.

F

I watched but I'm working on it I represent me. Sir, are.

A

There anything flora Poste, you guys want the reviews on or they start to pay a dollar.

F

But having worked on it and I finally,.

F

A

Was there anything rigid with Jade poll that we should face.

A

G

Now on gets me public.

A

Susie get you a gift.

G

A

B

Are a few things like? It should be a option where, like that, for instance, when, when Jace for when Jace form, then you don't want to reach it like you, don't want to redo the gene back in JQ bagging, for instance, so you need some sort of like a switch where it triggers in like once, when you're generating it I.

B

D

That for IP for.

B

Instance, it was like acutely sensitive because I wanted that sensitivity. Then I, don't when I'm computing, the JPEG and James bad, and you don't really need to do that, but sometimes like it should be an option. For instance, if I are doing a big problem venom you.

D

Don't want to format.

B

So it like get both functionality, but it somehow user can choose yeah.

C

Me following at state lion one set up so that you can also just occasion make just get out. You know a full Jade that could not necessarily the whole earth, sir full Jade, but not necessarily with all the data, but just you know sounds specific just because you want to test this. You want to kind of get a sense of what this is looking like for that and.

B

Yeah in terms of that, just using JT back or J paddock, it's not really working so like a thing. I ended up.

D

B

Just like a forming J, so it's basically some very similar to JT back yeah, but that there's a little bit of difference.

A

B

Like that cuz you're using J back yeah exactly member, that's some part there's some part that makes it really expensive. Then you're recomputing, a few.

E

Other things and.

B

Jt back yeah, but you.

E

D

Smart enough, like looking.

B

To be flat, yeah probably the example not yes,.

A

I mean usually M paper. All we did is identity matrix, yes, which is a little bit silly way to do it right.

B

So usually, JT bag is better than MJ. It's okay, you're. The number of solve is the number of theta yeah, so it's usually better yeah. That's.

D

Basically, like that same that.

B

Looked what's called joint yeah.

B

So they're few few few things.

C

B

Probably good to have like a function or get J or something like that, as as we have JPEG and treats you back in the inaudible class yeah, and we sure we can generalize it or but like anyway, problems.

A

A

Yeah I would be tempted to call it so you're that GT back every time, so just called it Jay Paul. That's no! Although.

F

I kind of Becket's with racing 5025, it's a mind, n1j full when just once on Jays sailor who could get J off challenges, episode like there are like rose again.

D

A

Do you guys want to write up an issue on that? Just so we have it on the radar. Alright, kids, where you keep track of where we're at yeah.

F

How far is is the road.

B

A

He's not high Hawaii and so he's not really actively pushing on site at the moment, but he it still is.

G

A

You still, it has great when we chatted in the past, evokes tourism trying to both rely discretize their enough pieces.

A

E

That's on the rear, nothing else for a while, both Jim T relies on. In this brief history, dementia.

F

A

E

A

F

And what is fight is just a wrapper on top of the gym, yeah yeah jakey's knife, excellent yeah.

A

Yeah he gave you talk on this here. Yeah.

F

I'm, a beautiful mouse.

A

Who's playing at the Autry and ready yeah.

B

Yeah I think he has a few questions about how to generate smash. Okay, I, don't like that court, its it core something: water fence, I, don't disguise water right.

A

B

D

Yeah and I've never made.

G

Any measurements.

D

With it so big I've always created all my messages like outside, with the UVC stuff yeah and then just pull them in for them. Yeah.

A

They're different ways in place, thinking about it actually there's a cool.

A

So this is actually a decent example that maybe shows you a bit of how it works. So when you want to refine an octree, much instant pay, you can give it a function. So in this case we give it a sign and said, like give me a mesh around this refine it. So this is the.

A

So we service it up and speed the base mesh and then we're gonna refine it by 3. So that gives us an courses cells that district lines the whole time and then here is actually going we're finding about this sine function. So it just refined.

A

Once is I think you can do this for fun function and then at number of times as well. So you can go in for final a bit so we're playing around with and probably hitting on a bit like in terms of documentation and examples.

F

Triangles yeah.

F

You know have to be able to find a match price on that triangle. It wants yeah, because then we can throw in services and yeah you pretty much right.

D

Yes, the way the UPC, so it doesn't, is you just it kind of looks to see where your electrodes are okay and then it has kind of different zones, different levels of refinement. You could set in proximity to your lectures and so points.

D

So you just say: I want to make sure I have ten when I find it sells everything except even per direction. Okay, so you just say like I want ten fine cells around each one unlock each other's does that you can set different, so 25m cells. Then I want six of my next small cells and then you can kind of control. How quickly you of course too, because sometimes I could make a big difference so.

C

In cases like that, where you actually have you know a code that seems to be working.

C

What's what would be the procedure for actually taking look at code like that and then just sort of okay there's enough to not transfer it over to to to Python or somehow integrating it or I mean weird? If weird is one so you'd like to have like have a good octree machine right and so we've got something and then there's about a dozen other packages out there, but one here, that's actually seems to be satisfactory for a lot of problems yep.

C

So how do we take that and then just sort of somehow fold into it doesn't pay let's? What's the best way and.

A

I mean I think the first thing is just finding the smallest piece of functionality that would want to bring in, like don't think of it as too tired mesh generating package. Think of like each function has its own thing yeah and then go after like what are the ones that are most useful or valuable to people. Listen, I, don't think like it's, not a code translation, because that we doctors are thought over different.

A

That's okay, the.

B

Minimum level it's like yeah well I think how Mike is doing. It's probably the minimum burning rubber ones say you used whatever you have, for instance, might please Jeff Curtis to carry on finish and you have a certain I.

D

B

Can we need to sit that much class so he can use that match.

B

Certain minimum level right still owes I think all people uses, but in depth kind of workflow, first say G.

D

B

Pretty famous match.

B

Tetrahedra, so they can use that G mesh usually and then, however, have stops have some I owe them. Can we need to their program and discretize? It.

C

So without any goal here is taxing me, you should G mention of some of these other things were to basically reprogram everything.

B

I don't know like that's what carries code use? What was.

D

G

I give me you yes to.

B

Generate it's like a GUI yeah ja. This is my domain. I want to discretize my.

B

Triangles yeah not sure that works for three.

A

If using the you see you press generator and then just translating that into something, it's what's needed, that's fun like if we start hitting on stuff like empty, doing multiple meshes and I, think that will drive some development to get quickly generate some pretty simple messages.

A

B

I think we probably want to have a similar functionality with we have four tensor insurance, doing a very simple algorithm pad like this. That won't have a core like corn mash, as it was just basically a tester match up everyone's path. That's like when I walk out really fancy color to it, refine things, but then hungry.

C

You know, there's there's basic system: you've got typography right, see another fine, fine, mentioning about typography. You've got transmitter or a receiver, so you need to be good there and then you may have some. You know here: extreme conductivity contrast or something where you're gonna have breath. That's some pollination. So many! Those are those are kind of look base base elements. Okay, we have to have some flying discretization, yeah, of course, wave them yeah.

A

I mean in so each.

C

Of those cases.

A

We do actually have the functionality to deal with. It's just examples, because in.

C

This case, if you had a conductivity.

A

Model the iron as a function or on a base mesh like that, can easily be translated to whisper and if-else kind of.

C

So if I had to partner to, for instance, here yeah the pathway through that sign up good being air yeah right, so that would be funny then store. This final.

A

A

C

Very offensive surface towards points and wish, but I'm sure, basically its surface yeah.

A

So then, all you're basically saying is look here is this surface, but this is just a sign, yeah and then say it for any dishes with we're fine.

C

A

C

That that's that's got here now, you're going me to put the transmitter and the receiver yep and then how do those particles kind.

A

Of interact so.

C

A

You can basically do another layer of her.

A

Then you basically.

A

So we can refine multiple times, we've done it once and now there are five get it correct. So.

F

That's what we only need you need to be able to be fine refine on travels for all the settler, with them with training that surface and once we have both. This is good as sine functions like this sir. It's easy, whether we never have shamsher but.

A

In this case, do you have to define some sort of if, like just a conditional phone so like this, is a conditional on a sign? There's, no reason.

E

Yeah something slightly more involved so.

C

Do we do have you used this to kind of generate, let's say a mesh that actually does have like to Harvey and then it's the flat scale. It sells around that and then you know your DC resistivity potential electrodes of the current electrodes, as well as somebody inside right.

A

It's not that it can't be done.

F

Because we have these count, active cells on Coco, yeah, so I'm theory, we know I'm already how to select which cells are attached. To my bothers me, yes again for this yeah, you can pass it yeah.

D

There's some model things that you can say it active you just.

F

A

More so um what you actually know.

F

Can double it? You don't we.

E

Don't mean that we don't we.

F

Also, haven't just good to get that service yeah.

E

It's actually easier just his.

A

So to find something is face and say: I am this far hungry yeah.

F

So long term and that Canada I can I brought something like, like all our I, those are kind of dispersed everywhere on the man. You know so we're developing that CDC readin right out. If you see because we needed at some point yeah, it makes sense eventually, if you just collided all into one one little synthetic type of class yeah right because before I'm just looking for right now, okay, neither little Dylan- and you know.

F

Some observation file- yeah, it's gonna, bury it would.

A

Be good immediate if his utils, obviously you.

F

A

Assistance yeah, so if we actually could sort of take stock of where things are I, don't think we have too much duplication discretized. How trying to call a few things. But there is this: where you're going to kiss and completely undocumented functions, so people can't find them yeah. So even if going to you're gonna, just these first office together doc string, so it's a kids soccer what we've got or Tiffany good!

A

Yes, I! Think this.

D

A

You should take the long term cuties, like everyone, pull pull the pieces of the part, because right now it's just really hard to move soon, page because it's big.

A

So let me give a piece in matok and I'm doing something dis, Britt NPM, like we want to try to push all that stuff forward. That's a bit hard to do just in terms of littler quest reviews, and it takes a lot of time right so down the road. We might want to think about what sort of packaging each of the minutes early, but.

B

Host you want to break apart, essentially.

A

They gave a lot of ways. What I could see is doing is distributing it and similar to how Jupiter it distributes like when you actually install Jupiter you're, installing, like six or eight packages, and so right now, we've got that same peg is now in two pieces, but they.

A

But it doesn't have been a good point Don and to like with opportunities and sort of sinking forward. It is actually works. I mean even if you've got your your workflow working with.

A

Just kind of keeping.

F

Yeah I can move stuff from where this birthday our intuition go, that it's not every other import-export yeah.

C

So long, what are you auditioning there? Okay, you can try to answer to have one during much of what.

F

Entity that that's all of these- yes, for instance, like um that static, has importers or for observation, these observations, 2d or 3d. So we are we've already written those already em, but they were buried under you need to create that survey and you certainly get redone or whatever well.

D

F

Could just be a synthetic that you're readin you see and then it spits out the survey actually.

E

F

That you have done yeah.

A

It's basically defined what we expect for ya and then once you've defined that structure, it's easy to say like Jenny I, oh right, it's time to redefine the interface will.

F

You invite the other, because I think we like a match, because the I euro is good for anything.

A

Like it's quite sort of I think with your specs, but is not necessarily that we want like a separate utils package, but it is nice to have things that where these, where belong in the sense of like a period, if you're bringing in you CDC buggy, surveys like that should happen in tcpip, not in some. Oh okay,.

F

You tell something else to do anything: okay, I.

A

Think reinsert me separate inside outside, but I think that the application needs to be close to yeah unless something that we can use like properties, and it would be we're just having a look at the open mining format stuff that Roman and Franklin have done, because that is more sort, defining a rigorous structure, around geologic structures, so lines or holes, services and being rigorous. Look how to work with those type of data. And so they did a really good job at organizing that and then basically beyond the rate parsers that can bring in like cheers.

A

Hock, keng plays an advert movie frog, whoever their.

E

A

That's the next example.

E

I think what we want to try and get.

B

Hold the flourish.

A

Oh yeah, that's a good point. um We need to get this which has not come for it. So the people who knows.

A

Leo has done it before, so he did that with Fernando. Franklin has done it enough properties, so all of our dependencies are on condo or condo porch, which means it shouldn't be hard to get both.

A

So there are good people to contact, so it's not apparently in such a card, I just I haven't had time to look at it. You probably won't so yeah jump in there and.

F

What is it exactly just that you lose it into one once acutely, yeah.

A

And even the little wheels and like they'll filled four other systems and test em, so yeah. It's.

D

A more stable way to distribute.

A

Because right now we're trying to build all the wheels doing that on like activator, but like we're, not spitting up every imaginable Windows machine and so yeah some people. It's your sock.

F

That's the major roadblock right now, like people install something on yeah. It tastes like in two hours like yeah, which.

E

Is like stop, it's always the same thing as failing.

A

F

A

Yeah I'm feel free to ping, Franklin or Leo. I know that maybe have your help because they've already chimed in.

E

On the issue ever PC I can't the schematic.

F

B

I, don't like a window machine third, virtual virtual and.

A

Committing is nice to just have stuff.

F

E

F

Good for kids, it's really.

E

F

The momentum yeah sure that we're still working on doing.
