"Lucida Grande", Helvetica, Arial,

good in-distribution generalization performance, but
struggle with out-of-distribution generalization. This
is especially true in the case of tasks involving
abstract relations like recognizing rules in sequences,
as we find in many intelligence tests. Recent work has
explored how forcing relational representations to
remain distinct from sensory representations, as it
seems to be the case in the brain, can help artificial
systems. Building on this work, we further explore and
formalize the advantages afforded by 'partitioned'
representations of relations and sensory details, and
how this inductive bias can help recompose learned
relational structure in newly encountered settings. We
introduce a simple architecture based on similarity
scores which we name Compositional Relational Network
(CoRelNet). Using this model, we investigate a series of
inductive biases that ensure abstract relations are
learned and represented distinctly from sensory data,
and explore their effects on out-of-distribution
generalization for a series of relational psychophysics
tasks. We find that simple architectural choices can
outperform existing models in out-of-distribution
generalization. Together, these results show that
partitioning relational representations from other
information streams may be a simple way to augment
existing network architectures' robustness when
performing out-of-distribution relational computations.</blockquote>

<br>
My personal take on the current symbolist
controversy is that symbolic<br>
representations are a fiction our non-symbolic
brains cooked up because<br>
the properties of symbol systems
(systematicity, compositionality, etc.)<br>
are tremendously useful. So our brains
pretend to be rule-based symbolic<br>
systems when it suits them, because it's
adaptive to do so. (And when<br>
it doesn't suit them, they draw on "intuition"
or "imagery" or some<br>
other mechanisms we can't verbalize because
they're not symbolic.) They<br>
are remarkably good at this pretense.<br>
<br>
The current crop of deep neural networks are
not as good at pretending<br>
to be symbolic reasoners, but they're making
progress. In the last 30<br>
years we've gone from networks of
fully-connected layers that make no<br>
architectural assumptions ("connectoplasm") to
complex architectures<br>
like LSTMs and transformers that are designed
for approximating symbolic<br>
behavior. But the brain still has a lot of
symbol simulation tricks we<br>
haven't discovered yet.<br>
<br>
Slashdot reader ZiggyZiggyZig had an
interesting argument against LaMDA<br>
being conscious. If it just waits for its
next input and responds when<br>
it receives it, then it has no autonomous
existence: "it doesn't have an<br>
inner monologue that constantly runs and
comments everything happening<br>
around it as well as its own thoughts, like we
do."<br>
<br>
What would happen if we built that in? Maybe
LaMDA would rapidly<br>
descent into gibberish, like some other text
generation models do when<br>
allowed to ramble on for too long. But as
Steve Hanson points out,<br>
these are still the early days.<br>
