Just as a general response to the objections to this: The goal was to use XOR and PARITY as simple tasks and formal languages that exhibit a larger problem with the architecture. The unfortunate side-effect of this is that the most straight

Yeah the issue tends to be as the length increases the performance drops off. Your approach reminds me of Hattie's work: https://arxiv.org/pdf/2211.09066.pdf I do wonder if the observable drop-off in performance

I guess I should say the recurrence growing as a function of the input size is something people don't seem to be willing to afford, not specifically the linear dependence. Not to mention parity here is a toy problem to highlight the is

Yea this is a good solution so long as the task that needs to be outsourced to, say a python interpreter, is explicitly known and can be prompt engineered.

Recurrency will help, see the empirical results in this paper: https://arxiv.org/abs/2207.02098 . LSTMs can solve the PARITY problem, generalising to longer lengths of the problem without issue. The issue with re-intro

I was personally quite appalled that so many people believed this was what it was doing, but I suppose since the source was a DeepMind researcher, it lends a lot of credibility. By the same reasoning, I hope people do realise that there are

Isn't the CNN a discovery in itself? Without it, we'd be following the bitter lesson and "leveraging computation" to throw more data / compute at an MLP. Clearly someone felt that there'd be a better inductive

I've seen many interpretations of this article and I'm curious as to the mainstream CS reading of it. One could look at the move from linear models to non-linear models or the use of ConvNets (yes I know ViTs exist, to my knowledg

I'm interested to hear what these techniques are. Decreasing the generality will help, but I fail to see how that scopes the output. At best that mitigates the errors to an extent.

I think part of the issue is what level of explanation is satisfactory. We can explain how every linear transformation computes its output, but the sum of it is in many ways more than its parts. Then there are efforts that look like this on

Ya I guess I was comparing the difficulty of learning to "produce mostly grammatically correct sentences in most cases" to continual learning. From the 'inside' it feels like everything OP said is just the opposite.

Grammar is surprisingly easy to learn from unstructured data, to an extent. (source: I spent a lot of my PhD doing this kinda thing.) Continual learning seems to be a tough problem though, from what I'm seeing of my friends working on

How I imagine what you're thinking of is a kind of small update to an existing model by doing backpropagation training on 'new' data. There are existing problems with that, one keyword to lookup is 'catastrophic forgetti

Like the earlier responses said, if it is retrieving information from an external data source, that would be a much easier way to update things. REALM ( https://arxiv.org/abs/2002.08909 ) comes to mind as an example of a

It's definitely not to the extent that Israel is surrounded by states hostile to it, but I think there is some grounds to claim this, depending on how far back you want to go: https://en.wikipedia.org/wiki/MacDonal

We consider Malaysian a nationality, and Malay an ethnicity. I can see how it's confusing since Chinese and Indian are also nationalities.

Nitpicking here, but while the authors do use a recurrent neural net (RNN), they do not use it exclusively. The system consists of a memory element, and a controller element. In their evaluation of the system, they use both a standard feed-

The paper discusses putting the NTM through several tasks, and tests for "overfitting" or how well it has generalised the task by giving it a slightly longer task than it has seen during training. For example, in the copy task, th
