B
C
Good
yeah,
I
guess
I
can
start
people
may
be
coming
in
later,
but
first
of
all,
how
are
you
guys
doing
so
far?
If
you
find
anything
you
want
to
follow
up
on
that?
We've
talked
about
in
the
meetings.
D
C
D
D
C
Good
yeah
that
sounds
pretty
good,
yeah,
yeah
I.
Think
cell
cycles
really
neat
area
like
just
in
terms
of
like
understanding
how
cells
divide
and
you
know
the
timing
of
it,
especially
yeah
I
used
to
work
in
the
area
of
so
cellular,
reprogramming
and
I
was
like
one
of
the
main
things.
If
you
want
to
understand
how
it
like
how
cells
sort
of
you
know
reprogram,
one
of
the
things
you
have
to
understand
is
like
how
they
divide
and
like
what
happens.
You
know
when
they
decide
to.
C
You
know,
convert
to
a
different
fate
or
not
yeah
so
and
then
so
you're
just
kind
of
working
on
the
cutting
edge
of
that
area
like
they
take
it
yeah.
So
that
sounds
pretty
good.
Maybe
at
some
point
you
can
give
a
short
you
know,
presentation
and
if
any,
even
if
it's
just
on
what
you
do,
that
would
be
good
yeah.
C
Let's
see,
jesse
has
a
comment
mostly
feeling
my
word
way
towards
a
specific
ml
project
when
that
said
on
one
yet,
okay,
so
I
guess
yeah.
Let
me
talk
about
the
pre-training
models,
so
I
mentioned
in
the
email
that
I
was
thinking
more
about
pre
train
models
and,
as
we
talked
about
last
week,
we
have
these
models
that
are,
you
know,
kind
of
we.
We
want
to
use
them
to
sort
of
classify
training
data
so
that
we
can
build
a
nice
model
for
some
problem
that
we're
interested
in
analyzing
data.
C
C
D
E
C
Yeah,
actually
that
was
might
we're
gonna
mean
my
point
on
this.
You
know
I
think
that
one
of
the
problems
we
have,
of
course
we
saw
in
the
digital
vessel
area
stuff,
so
we
don't
have
good
models
for
biology.
We
have
good
models
for
like
will
same
language
and,
like
you
know,
maybe
cars
or
you
know
trees,
but
we
don't.
You
know,
maybe
more
general
problems
too.
Well,
we
don't
have
a
good
set
of
models
for
biology,
and
so
it
does
require
I
think
specific
sort
of
model.
C
C
C
This
is
like
pre
trained
models
for
developmental
biology.
That's
what
I'm
calling
this
and
in
this
image
here
is
actually
a
sort
of
a
graph
of
a
lot
of
the
pre
trained
models
that
exist
and
they're
in
this.
In
this
case,
they're
measuring
the
number
of
operations
it
takes
to
sort
of
train
one
of
these
versus
the
total
accuracy.
C
So
you
know
with
these
pre
trained
models,
you
can
throw
them
at
a
problem
and,
like
abraham
said
you
know
you
can
it
might
take
a
while
to
train
it,
a
good
accuracy,
but
you
also
have
to
worry
about
it
over
a
fitting
or
under
fitting
your
data.
So
you
know
if
it
over
fits
the
data,
it
will
predict.
You
know,
you
know
predict
that
anything
is
a
feature
if
it's
under
trained
it
won't
find
any
features
at
all
in
your
data.
C
C
You
know
it's
C
elegans
embryo
Genesis,
and
this
is
your
soft
lumber
Genesis
and
you
can
see
like
the
the
embryo
genetic
process,
is
very
different
in
these
two
organisms
in
Drosophila
you
get
this
cellular
ization
and
you
have
many
more
cells
that
are,
you
know,
forming
some
sort
of
shape.
That's
going
to
become
the
larval
stage,
C
elegans,
you
have
the
same
process,
but
it's
largely
cells
dividing
and
moving
around,
and
then
they
form
you
know,
wait.
They
have
like
a
comma
stage
and
they
have
other
stages
where
they
take.
C
C
So
if
you
go
from
embryo
to
embryo,
you
know
it
isn't
it
in
C
elegans,
for
example,
it's
highly
programmed,
but
it's
still,
there
are
still
variation
in
the
process,
and
so
the
variation
is
a
typical
say,
like
a
bunch
of
phases
where
we
can
characterize
human
faces
may
get
a
pretty
good
handle
on
you
know
a
face
is
a
face,
but
with
an
embryo
we
don't
really
know
that
so
I
mean
you
know.
We
talked
about
pre
train
models
and
you
know
how
they
might
be
used.
C
It's
basically
taking
a
say,
neural
network
and
defining
the
parameters
in
advance
like
some
of
the
connections
and
and
then
people
can
use
them
to
train
their.
You
know,
put
training
data
in,
and
you
know
kind
of
get
an
answer
for
their
problem,
but
in
biology
it
might
be
will
be
tricky,
but
one
of
the
things
that
I
was
thinking
about
over
the
week
is
that
we
have
models
of
biological
processes,
especially
models,
an
app
like
a
I'll
call
it
a
neural
network.
But
one
of
those
is
the
perception
of
biological
motion.
C
So
this,
in
this
case,
in
biology,
we
have
motion
in
the
embryos
or
you
know,
whatever
we're
looking
at,
we
usually
do
have
motion
in
biological
systems
because
we're
looking
at
processes
for
this.
In
this
case,
we
actually
have
a
model
of
perception
perception
of
motion
and,
and
what
this
is
is
it
comes
from
psychology
actually
in
in
the
middle
of
the
last
century,
a
number
of
ecological
psychologists
started
looking
at
biological
motion.
So
what
this
is
is
well.
If
you
look
at
wave,
look
they've
been
walking
individual
like
in
this
case.
C
You
have
two
people
walking
across
see
on
the
right.
We
don't
recognize
like
the
whole
of
the
motion.
Well,
we
recognize
you
know
we're
recognizing
the
whole
of
the
motion,
but
we're
doing
it
in
a
way
that,
like
focuses
on
specific
parts
of
the
law
of
the
Walker
and
so
they've
boiled
it
down
to
like
these
points.
C
When
we
do
that
and
so
they
use,
then
this
is
very
similar
to
what
people
do
in
machine
learning
where
they
pick
out
features
of
the
object
you
don't
necessarily
have
to
analyze
the
entire
object.
You
just
pick
out
features
and
you
relate
them
to
one
another
in
a
way.
That's
like
makes
sense
of
it.
So
in
this
case
we're
looking
at
a
cognitive
model
and
in
a
cognitive
model,
you
have
some,
you
know,
input
some
sort
of
sensory
input
in
this
case.
C
It's
the
vision
of
like
this
biological
motion
and
you
pass
it
into
some
neurons,
which
are
which
extract
the
different
components
of
motion.
So
you
have
maximum
and
minimum
sets
of
features,
and
then
you
integrate
them,
and
then
you
represent
these
in
a
certain
type
of
cell,
that
is
called
a
template
cell,
and
this
leads
to
two
separate
decisions
derived
from
a
compact
representation.
C
So
what
the
brain
does
is
it
represents
this
information
in
this
way
that
we
see
down
here
these
different
points
that
are
moving
around
and
then
that
information
gets
integrated
into
an
entire.
We
know
you
know
we
recognize
human
movement
because
we
recognize
those
cues
and
their
movement,
and
we
recognize
that
as
as
movement,
so
you
could
actually
create
a
fake
situation
where
it
looks
sort
of
like
a
human
and
you
might
still
interpret
it
as
a
human
moving.
C
C
So
a
pre
train
model,
or
even
like
a
machine
learning
model,
is
mimicking
the
brain
in
some
way
and
so
we're
mimicking
the
brain
in
cognitive
models.
We're
mimicking
the
cognition
we're
not
necessarily
mimicking
the
brain.
So
if
you
look
back
at
this
model,
we
have
neurons
in
it,
but
we're
really
interested
in
the
representation.
C
Conversely,
something
like
the
Blue,
Brain,
Project
or
hodgkin
and
huxley
is
where
you're
modeling
a
biological
neuron,
but
you
don't
really
care
so
much
about
what
it
does
in
terms
of
cognition.
But
what's
interesting
here
is
that
these
pre
trained
models
and
deep
learning
models
sit
kind
of
in-between
this,
and
so
they
sit
in
between
cognitive
models
and
sort
of
like
you
know,
high
fidelity,
biological
models,
and
so
you
know
for
something
like
biology.
It
might
be
interesting
if
we
sort
of
you
know
adopted.
C
Maybe
some
of
these
attributes
as
well,
where
we
actually
maybe
used
something
that
resemble
more
of
a
cognitive
model
than
a
typical
pre
tree
model.
I
only
say
that,
because
you
know
we
know
how
to
interpret
biology.
We
in
developmental
biology,
there's
a
history,
people
kind
of
looking
in
under
microscope,
slides,
and
you
know
interpreting
things
through
drawings
or
through
some
other
hive
Annette.
How
are
you.
E
C
E
F
F
C
C
And
so
I
was
mentioning
that
we
may
be
able
to
do
something
interesting
by
mimicking
cognitive
models
rather
than
something
like
a
typical
pre-training
like
I'll
make
these
slides
available
to
people.
We
can
have
a
discussion
about
this.
You
know
we
could
do
it
here
and
then
we
can,
this
later,
so
I
didn't
want
to
get
people's
feedback,
so
this
is
sort
of
paper
called
cognitive,
computational
neuroscience.
So
this
isn't
from
like
the
machine
learning
literature.
This
is
more
of
a
cognitive
neuroscience
approach,
but
you
know
that
there
are
ties.
C
There
is
one
that
just
came
out
and
this
is
actually
as
it's
very
closely
allied
with
biology
and
that
it's
a
deep
learning
kit
for
looking
at
animal
poses
and
movement,
and
so
this
is
deep
pit,
and
this
is
something
that
there
are
people
in
here
who
have
done
like
collective
behavior
and
emergence
type.
Work
like
e'en
cruising
does
a
lot
of
stuff
with
like
bird
flocks,
so
I
mean
that's.
C
Where
I
think
these
people
are
coming
from
on
this
they're
they're
from
like
an
animal
behavior
kind
of
background
and
they've
developed,
this
kit,
which
is
a
set
of
animal,
poses
and
they're
able
to
estimate
movement
from
that,
and
so
this
gif
isn't
running
here,
but
it
shows
a
bunch
of
things
moving
around
and
they're
able
to
predict
the
movement
from
that,
and
so
you
know
in
in
this
case
you're
not
using
a
traditional
pre-trained
model
but
you're
using
something
that's
inspired
by
sort
of
what
we
know
about
animal
behavior,
and
so
in
this
case
there's
something
called
a
stack,
that's
net
bottom
and
so
they're,
using
this
sort
of
process
where
they're
taking
input,
images
and
they're
augmenting
them
using
augmented
data.
C
So
here
in
the
Augmented
data
augmentation
strategy,
they
have
this
input
of
a
fly
and
then
they
have
it
in
different
poses
you
know,
and
so
when
the
fly
is
moving
they're
in
these
different
poses,
you
take
static
images
and
put
them
together,
and
then
you
run
this
Network
there's
some
math
here.
The
basic
idea
is
that
you're
able
to
take,
you
know,
features
and
a
you
know.
C
Some
of
these
poses
and
put
them
in
a
graph
and
then
get
some
sort
of
prediction
of
movement,
but
the
movement
you
know
is
based
on
sort
of
what
we
know
about
the
biology,
not
necessarily
just
well,
here's
a
model
that
you
know
works
on
language
processing
or
on
you
know,
classifying
cars
and
we'll
apply
it
to
movement.
So
they
took
the
bull
of
a
different
approach
here,
but
still
this
isn't
a
cognitive
model.
C
But
then
there
are
also
other
types
of
free
training
models.
One
that's
has
a
very
lengthy
blog
post
behind
it
is
I,
have
a
GP
to
mock
EPT
to
model,
and
so
this
is
an
example
of
a
pre
train
model
for
language
processing,
where
they've
been
able
to
train
it
on
language
processing.
But
you
know
if
you
use
it
for
another
purpose,
you
know
you
might
not
get
the
kind
of
result
that
you
want
and
again
it's
like
very
good
for
its
test
domain,
but
it's
not
enough,
doesn't
necessarily
transfer
very.
C
C
C
You
know
you
might
not
want
to
have
a
lot
of
input
data
or
rely
on
that,
because
you
know
it's
you
just
don't
have
the
data
that
you
can
throw
at
it
and
this
and
this
blog
post.
You
get
an
idea
of
the
scale
that
you
need
and
it's
it's
a
little
intimidation,
but
that's
that's
how
they
that's
what
sometimes
they
need
to
do
to
to
make
these
pre
train
models
work.
C
Another
example
from
language
processing-
and
this
is
an
area
called
NLP,
which
is
your
linguistic
programming.
It's
called
fast
bird
and
this
is
a
simple,
deep
learning
library.
So
in
this
case
they
do
two
steps.
They
do
like
a
semi,
supervised
training
step
on
a
large
amount
of
text,
so
they
just
you
know,
throw
a
lot
of
data
in
it
and
then
the
next
step.
They
supervised
the
training,
they
label
a
data
set.
They
put
that
into
the
algorithm
and
they're
able
to
benefit
from
the
semi-supervised
stuff.
So
semi-supervised
means
that
you
have
text.
C
That's
you
know.
Sorta
has
labels
and
sort
of
doesn't
you're,
throwing
you
know
words
at
the
bottle.
Sometimes
it
knows
the
context.
Sometimes
it
knows
you
know.
Sometimes
it
knows
the
meaning.
Sometimes
it
doesn't
they're
allotted
you
know
it's
it's
very
diverse
in
that
way,
and
then,
with
the
supervised
training,
you
have
something
with
a
formal
label
and
then
from
that
they
can
create
a
tree
train
model
that
can
encounter
a
lot
of
different
cases.
But
in
that
you
know
in
in
this
case
again,
you
need
a
lot
of
input
data
to
do
it.
C
So
that's
all
I
have
for
this.
I
just
wanted
to
go
through
a
couple
of
pre
tree
models
and
get
a
little
bit
of
feedback
from
people
as
to
what
they
you
know.
Maybe
they
they
think
about
like
pre
train
models,
maybe
Jesse
actually
mentioned
he
was
interested
in.
You
know
pursuing
that
a
little
bit
further,
at
least
in
terms
of
thinking
about,
like
you
know
how
we
might
create
one
for
biology.
So.
C
D
So
you
have,
on
the
one
hand
you
have
human
ossification,
which
requires
internet
education
right
as
well
and
in
in
general
you
will
also
have
simple
sanitation
problems
and
I
guess
there
are
a
bunch
of
other
types
of
ruse
that
you
could.
You
can
attack
with
no
networks
pretty
effectively
and
I
think
there
there
are.
D
D
D
D
Are
currently
different,
we
don't
have
a
general-purpose
nor
network
structure.
Yes,
that'll
do
any
tax
key,
throw
it
in
the
thinkin
I,
don't
listen!
You
know
that
my
work
that
way.
Either
we
use
different
network
structures,
different
paths
and
then
we
supervise
which
one
we're
passing
it
to
us.
That's
sort
of
our
brain
works.
It's
centralized,
but
it's
still
solely
attributed
processing.
You
have
these
regions
on
the
cortex
that
are
associated
with
different
behaves
right.
You
have
a
sensory
monkey.
That's
this
way
right
on
your
brain
cortex
and
you
have
a
visual
process.
D
Okay,
all
these
other
structures
that
are
associated
with
specific
types
of
processing,
tasks
that
have
the
appropriate
network
architecture
for
those
particular
tasks
and
then
there's
some
sort
of
classification
that
passes
the
problem
to
the
right,
neurons
right
and
so
at
the
end
of
that
I.
Don't
necessarily
know
that
you
can
get
to
a
general
purpose
solution
by
building
a
single
Network,
so
much
as
building
a
bunch
of
very
specialized
networks
and
figuring
out
a
way
to
figure
out
when
you
want
right
now.
The
problem
is
I.
D
C
A
E
C
There
you'll
be
able
to
turn
I
mean
that's
kind
of
the
principle
behind
statistics.
You
know
that
you
can
take
a
measurement
and
then
apply
statistical
tests
and
then
no
matter
what
your
data
is.
If
it's
like
you
know,
defects
in
manufactured
goods
or
like
people
in
a
sporting
event
or,
like
you
know,
cells.
C
You
know
it's
just
like
a
broad
range
of
things
that
you
could
measure,
but
you
should
be
able
to
use
this
one
set
of
tests.
I
mean
now.
You
know
there
are
a
lot
of
statistical
tests,
which
maybe
suggest
that
you
know
that
kinda
universality
isn't
really
doesn't
really
exist.
There
are
a
lot
of
assumptions
that
need
to
make,
for
you
know
different
problems.
C
So
yeah
I
agree
that
you
have
to.
You
know
that
I
don't
think
that
there
is
necessarily
a
general
solution,
but
that
barrier
to
entry
mentioned
is
actually
pretty
important
to
I.
Think
you
know,
I've
seen
a
lot
of
people,
they
kind
of
jump
into
the
myself
included
kind
of
jump
into
the
area,
and
it's
like
you
know
what
is
the
best
model
for
the
kind
of
data
were
using.
That's
why
I
did
this
I
wanted
to
focus
on
this
a
little
bit?
A
D
To
ballistic
data
and
the
closest
that
I
could
get
for
that
was
well,
we
got
a
sequence
data
which
is
the
Raymond
urbanised,
is
one
the
benefit
and
you
can
in
principle
break
it
up
into
units
that
are
working
in
our
genes
and
promote
a
very
alarm,
contributed
language,
that's
us,
and
then
you
can
attempt
to
use
that
power
to
your
first
problem
of
person
of
information.
But
it
doesn't
it's
a
very.
C
D
C
I
think
that's
I
think
that's
very,
very
good
observation
to
like
you
know.
I
know
this
that,
like
in
very
early
bioinformatics,
they
used
to
focus
on
you,
know,
gene
sequences
and
then,
like
you
know,
you
can
use
a
linguistic
models
like
a
lot
of
people
like
to
use
hmmm
models
which
are
hidden,
Markov
models.
C
You
know
that
are
kind
of
for
both
you
know
linguistics
and,
for
you
know,
sequence,
data
and
it
works.
But
then
you
know
it
depends
on
what
you
want
to
get
out
of
the
sequence
data.
If
it's
you
know
it's,
it's
not
really
structured
exactly
like
language,
so
you
have
to
find
a
model,
that's
sort
of
abstract
enough
to
deal
with
that.
But
then
you
know
there
are
certain
assumptions
of
the
model
that
you
know:
don't
necessarily
fit
the
data,
so
it's
always
kind
of
like
you're.
C
You
know
in
and
I
think
a
lot
of
times
in
bioinformatics.
In
particular,
they
try
to
modify
the
models
to
sort
of
fit
into
the
assumptions
you
know
so.
There's,
like
you
know,
they're
like
platforms
like
you
know,
they
might
use
a
hidden,
Markov
model,
but
they
might
have
you
know
they
might
tweak
it
to
conform
to
certain
assumptions
about
gene
sequence,
data
that
sort
of
thing.
So
it's
it's.
C
You
know
it's
it's
good
to
kind
of
look
at
what
other
areas
of
modeling
you're
doing.
Actually
you
know
you
also
have
platforms
like
go
back
to
agent-based
models
where,
like
you
know,
you
get
a
package
that
does
agent-based
modeling
often
times
they'll
come
with
templates
which
are
like
you
know
they
have
different
sort
of
scenarios
built
into
them.
So,
like
you
know,
you
have
an
agent-based
modeling
program
and
it
has
like
models
for,
like
famous,
you
know,
cellular
automata
models
or
they
might
have
models
for
you
know
different
game
theory,
game
game.
Theoretic
games.
C
I
was
just
working
with
a
package
we're
looking
at
like
like
prisoner's
dilemma
models,
so
you
know,
you'd
have
a
agent-based
model
and
you
know
you
go
in
and
you'd
say
well.
This
is
a
good.
You
know
you
know
so
I
guess
a
sub
model
for
what
I
want
to
do.
I
want
to
look
at
this
problem
in
terms
of
the
prisoner's
dilemma,
and
then
you
know
you
might
have
variations
on
that
and
it's
all
so
pre-code.
A
C
D
D
D
And
using
the
model
human
behavior
by
removing
half
of
those
variables-
and
you
know,
there's
precedent
for
doing
this
sort
of
a
test,
but
at
the
end
of
the
day,
as
we're
hugely
shown,
those
models
that
you
know
a
lot
of
patients
don't
to
attract
leakage
on
a
model
include
behavior.
You
know,
because
there's
all
there's
a
lot.
C
D
C
Exactly
so,
yeah
I
mean
that's
like
a
like
a
whole
area
of
like
inquiry.
I
guess
I've
seen
a
couple
papers
actually
come
up
to
talk
about.
Like
many
people
are
kind
of
questioning
your
assumptions
where
you
know
you
find
something.
That's
universal,
like
I.
Think
power
laws
is
one
example
from
like
complexity
theory.
So
about
20
years
ago.
Everyone
thought
that
there
were
power
laws
and
like
networks
and
in
you
know
all
sorts
of
things
and
then,
like
you
know
now,
people
are
evacuated
insane.
C
Was
it
really
a
power
law
or
is
there
more
to
it,
because
the
idea
of
a
power
law
is
that
you
have
this
one
statistical
signature.
It's
supposed
to
be.
You
know,
live
alone
across
all
these
different
domains,
and
then
you
know
is
it?
Is
that
really
the
case
or
are
we
just
kind
of
looking
at
many
different
things
that
are
very
similar,
but
we
kind
of
use
a
statistical
model
to
you
know
claim
that
there
are
these
deep.
C
C
Like
I
said,
you
know
that,
like
there
may
be
cases,
there
may
be
opportunities
to
look
at
like
cognitive
models,
which
are
you
know,
models
of
how
the
brain,
actually,
you
know,
processes
like,
say,
bio,
biological
information
as
sort
of
a
sort
of
a
key
to
like,
maybe
how
that
can
be
done.
You
know
in
a
more
specific
way.
C
You
know
the
problem
is,
is
like
you
know:
how
do
we?
How
would
we
code
that
and
how
would
we
like
throw
data
in
it?
Would
that
be
something
that
would
be
feasible?
I
know
people
are
doing
like
using
cognitive
models.
Sort
of
to
look
at
you
know
you
know
maybe
for
like
data
analysis,
but
that's
you
know
it's
so
models
even
like
that
or
a
little
bit
tricky
to
implement.
E
E
E
The
same
experiences
sometimes
work
very
well.
Some
parents
may
be
my
choice
of
majority.
Selecting
of
the
model
was
bad,
but
I
see
how
experiment
a
lot
of
things
on
there,
a
pjr
for
picking
on
us
and
so
I
think
this.
This
useful
people
models.
We
encourage
because
a
person
looks
like
Elsa
flow
and
pipe
ouch
had
these
humps.
E
So
they
have
a
lot
of
missing
in
the
previous
mix
of
conventions.
Then
the
nurse
will
be
a
case.
There's
a
TF
naught
M
L
and
D
F
da
cleared
sandy
hook
onto
the
dark
layers,
so
there
are
different.
It
is
so.
What
the
major
update
to
what
I
see
is
that
they
remove
all
of
those
things
and
the
bonusing
will
be
a
recipient,
and
also
that
is
remember
it
so.
A
C
E
E
C
Yeah
I
think
we
can
trust
them
yeah,
it's
just
a
matter
of
like
you
know.
If
we
have
a
certain
type
of
data,
what
are
we
using
something
that
maybe
is
trained
in
a
totally
different
domain?
And
then
you
know
I
guess
the
first
question
is
you
know?
Maybe
is
there
a
domain
of
data
so
like
we
have
like?
We
got,
isn't
universal
necessarily
there
might
be
some
aspects
of
it
that
you
know
that
explain.
C
You
know
there
are
data
types
that
have
very
distinct
things.
So,
like
you
know,
if
you
had
a
bunch
of
M&Ms
on
a
table,
we
took
the
picture
and
you
asked
the
algorithm
to
pick
up
the
M&Ms.
You
know
if
you
used
like,
maybe
like
something
that
was
specialized
from
linguistics.
That
may
not
be
very
good
if
he
picked
something.
That's
optimized
for
object,
detection.
E
C
E
In
those
object,
so
what
we
did
was
we
remove
the
last?
Yes
that
please,
like
it
has
some
50
objects,
I
think
I,
don't
think
I,
don't
remember
the
number.
Also
we
remove
the
last
way
my
fees
of
the
model
we
remove
the
last
years
and
we
are
didn't
move
with
a
new
class.
That
is
a
cheetah
that
good
yes,
so
we
found
this
on.
Jobs
like
this
is
a
very
I
said.
C
Yeah
I
think
that's
yeah.
A
lot
of
those
kind
of
strategies
are
gonna,
be
useful,
yeah.
It's
very
interesting.
Let's
see,
Abraham
I
think
posted
a
link
to
paper
William
Bialik
who's,
a
famous
physicist
dimensionality
and
dynamics
in
the
behavior
of
C
elegans
I.
You
pick
something
that
is
even
worm,
approved,
I
guess,
let's
see,
I
think
I'm
I
think
I've
seen
this
paper
before.
C
So
this
is
a
major
challenge
and
analyzing
animal
behaviors
to
discover
some
underlying
simplicity
and
complex
motor
actions.
So,
yes,
this
is
ready.
Analyze,
the
behavior
or
the
movement
behavior
of
C
elegans
were
freshly
reconstruct
equations
emotions
from
dynamics
in
this
space
I
think
this
yeah.
C
C
You
might
find
it
interesting
if
you're
think
it's,
it
should
be
up,
it
was
done
for
a
while,
but
they
have
like
a
lot
of
movement
down
are
there
and
they
have
like
it's
a
movement
database,
but
they
have
done
some
analysis
on
this.
So
the
you
know
you
might
look
over
that
site
to
see
get
a
sense
of
what
people
were
doing
with
like
mu
were
movement.
Yes,
this
is
where
they
come
up
with
the
eigen
worms.
C
So
this
is
where
they
actually
take
the
data
and
they
boil
it
down
to
like
you
know
they
use
a
dimensionality
reduction,
and
so
you
know
there
there
are
a
lot
of
statistical
techniques
that
we
are
talking
about
directly
here,
like
dimensionality
reduction
and
other
things
that
are
nevertheless
actually
quite
useful.
Aside
from
the
hard
core
machine
learning,
algorithms,
like
things
like
effective,
is
there
anything
you
want
to
say
about
this
paper.
C
C
Yeah
yeah,
actually
I,
couldn't
hear
a
part
of
that.
Could
you
type
it
in
my
chat?
We
could
I
could
improve
it
back
to
the
group,
because
I
was
yeah
ever
broke
up
a
lot,
so
yeah
I
mean
this
is
this
is
a
good
example
of
the
kind
of
thing
that
you
know
and
again
this
isn't
like
machine
learning,
but
like
it's,
you
know
something
that
is
useful
so
like
in
the
movement
group.
C
They
take
a
lot
of
microscopy
images
of
more
movement
and
you
know
then
they
analyze
it
and
they
use
this
kind
of
space.
You
know
like
a
reference
space
for
the
movement
see
or
like
basically
finding
modes
of
movement
now
in
C
elegans.
That's
relatively
easy
only
because
the
arms
movements
are
stereotypical.
So,
like
you
know,
if
you're
analyzing
human
dance,
it
might
be
a
little
bit
harder
because
there's
a
lot
of
like
improvisation
and
there's,
like
you
know,
a
lot
of
different
degrees
of
freedom,
let
C
elegans,
of
course
it's
easier.
C
But
then
it's
maybe
not
as
easy
to
like
really
kind
of
confirm
that
you
have
modes.
I
mean
we're
just
using
the
human
visual
system
and
we're
saying
yeah:
we
can
see
modes
of
movement,
you
know
under
a
microscope,
so
I
mean
you
know,
that's
that's
what
I
don't
want
to
have
like
a
statistical
model,
but
then
you
know
this
actually
is
a
pretty
good
way
to
do
this.
So
you
know
they
use
this
term
eigen
worms,
it's
just
you
know
finding.
C
You
know,
eigen
eigen
values
and
eigenvectors
of
you
know
coming
from
the
these
movement
modes
and
then
these
for
Jesse.
He
any
he's
interested
in
attractor
basins
in
that
they
do
actually
use
attractor
models
of
movements,
so
they're
actually
able
to
create.
You
know
different
attractors
for
different
postures
of
the
worm,
so
there's
some
dynamical
system
stuff
in
here
as
well
yeah.
So
let's
see
what
what
our
Chet
we
have
here
in
the
chat:
okay,
yeah
yeah,
that's
fine!
Abraham!
Thank
you
for
the
paper.
C
I
was
very
interesting
so
and
then
Jesse
says
definitely
interested
in
the
cognitive
modeling
aspects.
These
slides
or
videos
will
be
online
somewhere
missing,
chunks,
no
and
then
yeah
I'll
post,
the
video
and
the
slides
else.
I
actually
posted
on
slack
for
you
Jesse.
Do
you
have
anything
else
to
add
or
any
thoughts.
C
Okay,
yeah,
that's
that's
fine,
and
if
you
have
any
questions
over
the
course
of
a
week
could
be
like
insights,
you
can
post
them
in
slack.
So
thanks
for
attending
okay,
it's
we're
coming
up
towards
the
top
of
the
hour.
So
next
week
we'll
see
what
I
can
get
someone
else.
Does
anyone
want
to
contribute
something?
Next
week
you
have
any
ideas
that
you
want,
even
even
if
it's
just
like
a
couple
slides
and
bring
up
an
issue
that
you
want
to
talk
about.
We
can
talk
about
it.
