From YouTube: Temporal Memory vs Temporal Pooling (Part 4)
Description
We discuss the difference between Temporal Memory as understood in current HTM theory and the Temporal Pooling functionality within sensorimotor inference.
You should have some background in HTM before understanding these videos. See http://numenta.org/htm-school/ for more videos explaining basic HTM theory.

The
cortex
I
was
relay
of
choose
within
upper
three
when
they
are
part
of
later
on.
Okay,
those
are
the
two
output
layers
in
the
cortex
5
would
be
output
of
motor.
Let's
not
go
this
the
moment
just
like
there
are
in
this
as
well
again
after
adjusting
as
this
is
well
understood,
neuroscience.
There
are
two
layers
that
have
cell
to
project
out
of
this
region
to
go
off
the
hierarchy
or
go
something
else.
One
of
them
actually
generates
motor
behaviors,
but
those
are
late,
5
and
late.
Retreat.
Okay,.
A
B
B
That
question
about
a
specific
question:
feedback
exists
everywhere
in
the
cortex
and
so
when
we
think
people
think
what
they
like.
So
is
your
feedback
in
the
hierarchy.
True,
that's
it
yeah,
but
in
this
case
we
have
feedback
from
the
output
layer
to
the
insulator.
I
talked
a
little
bit
about
that
right.
I've
talked
about
this
location.
B
From
layer
for
the
input
layer
back
into
the
cells
that
are
making
the
providing
the
location
information
that
then
remember
I
then
talked
to
help
how
it
goes
back
to
the
where
pathway.
Remember
that,
because
it
goes
both
ways,
yeah
usually
comes
in,
and
it
goes
back
to
pretty
much
everywhere
in
the
cortex.
You
know
you
have
bi-directional
connection,
the
distinction
is,
which
ones
are
driving
self
and
which
ones
are
biasing,
so
I
know
so,
like
layer,
four
projects,
the
layer,
two
three,
that's
pooling
layer
it.
B
Rain
water,
it's
right
just
depolarizing
themselves,
so
mid
them.
The
the
century
input
has
to
make
them
self
fire
right,
but
didn't
put
bias
ISM
to
make
this
specific
representation.
For
so
one
of
the
engineers
about
this
theory
is
that
there's
a
series
of
things
that
have
to
be
resolved
for
this
story.
I
just
reached
my
finger
into
a
box
I'm
about
to
touch
something
I,
don't
know
where
my
finger
is
on
the
object
and
I.
B
Don't
know
what
I've
become
tension
right,
all
I'm,
going
to
get
to
the
feature
and
somehow
to
a
combination
of
moving.
My
finger
around
I
have
to
be
able
to
determine
what
the
object
is
and
also
where
I
am,
and
these
are
sequin.
Think
of
this
is
encoding.
My
variables
I,
don't
know
the
answer
these
variables.
So
the
way
the
system
is
going.
B
You're
going
to
have
the
layers
of
cells
representing
things
like
what
the
object
is,
the
orientation
and
where
I
am
on
the
object
and
they're
going
to
be
forming
unions
of
representation
and
and
they
go
folder
and
they
go
back
and
the
whole
system
has
to
resolve.
The
whole
system
have
to
figure
out
okay.
After,
if
you
touch.
B
B
You
get
a
sensor
when
I'm
on
a
set
of
cells
or
when
you
form
a
set
of
a
union
of
representation
to
in
a
layer
self
it
projects
to
another
region,
and
it
forms
the
Indian
of
the
next
language.
Of
that
reason,
would
I
lay
ourselves.
So
all
these
guys
are
all
these
users
and
try
to
resolve
each
other,
but
there's
always
an
intersection
to
make
sense
sure
right.
So
there's
no
one
specs
are
going
as
individual
and
until
you
to
resolve
all
the
interview
'ti,
you
don't
have.
B
That's
another
cut,
it
sometimes
does
another
type
of
feedback.
So
we
are.
We
are
introducing
a
lot
more
feedback
in
this
model.
Then
we've
had
in
the
past
and
it's
in
multiple
places
in
the
classic
example
of
Oh
feedback
down
the
hierarchy,
we're
still
not
modeling
or
hierarchy
right,
we're
still
not
modeling
to
levels
higher.
You
still
believe
the
right
way
of
going
about.
This
is
understanding
where
single
region
doing
very
well
right.
So.
B
Not
just
a
feature,
it's
a
three-dimensional
feature.
If
you
will,
it
can
be
complete,
three-dimensional
object
and
that's
a
very
different
type
of
these
to
do
with
them.
Then,
if
you
just
think
it's
a
basic
feature
going
up
right,
so
we
really
want
to
nail
what's
going
on
in
every
region
and
particularly
the.
