The fact that a neural network isn't even able to calculate, even if only trained to do this show how limiting are neural network only AGIs.

Of course you could train a NN to do arithmetic, but this is much more impressive. Training a NN network to solve problems with available tools means more abstraction, and is closer to AGI than just essentially learning a LUT.

Are we really capable of teaching a NN to parse and calculate an arbitrary arithmetic expression? Because that sounds incredibly impressive...

Yes, it can be done.

Natural language is harder.

I'm not sure. Human is general intelligence, but has to learn basic maths too.

Here’s one that does so using roman numerals:

It’s unsurprisingly easy to implement

Interesting but can it do more than addition? Also it doesn't seems to have 100% accuracy.

Yeah. I only trained addition. Actually exploring the impact of training a net to perform a range of operations on the minimum plausible neuron count would be quite interesting

I don’t see any reason why it would be significantly harder to do, however

You’re right about accuracy. I didn’t let the model train enough to push the error low enough to guarantee exact results over the input range. But then again this was designed as a toy experiment, not something people should rely on
