Is it possible to know the family of functions a neural network approximates?

Is it possible somehow to find which family of functions a particular network approximates? For example, I have some directed graph and I use its vertices as artificial neurons (as simple McCulloch &...

Comparing Auto-regressive Encoder-Decoders and Topological Neural Networks

I am interested in what insights can be gained about the mathematical class of auto-regressive encoder-decoders (LLMs), by comparing them to topological neural networks. Specifically, I am looking for ...

Nearest neighbour search in high dimension retrieves certain points too often

We represent some catalogue items (documents, music tracks, videos, whatever) as vectors embedded in R^d and use them to retrieve nearest neighbours to users query. The typical scenario is that users ...

Behaviour of PPO/similar Algos under action penalties

I am currently experimenting with PPO in different environments. I am interested in learning policies that fulfill a certain goal while keeping a specific value low. Here's an example: Using PPO on a ...

How do I use the N correctly in NEATs speciation delta function?

When implementing NEAT I'm having some issues with the speciation distance/delta function, specifically the term N (number of genes in biggest genome). Won't term $N$ in $δ=c1*E/N+c2*D/N+c3*W$ just ...

Is it possible to find a good neural network structure without training it? [duplicate]

Neural networks consist of so many parameters. Researchers could create as many possible neural networks as they wish. So I want to ask a general question. Could we devise an evolutionary algorithm ...

Are Modular Neural Networks more effective than large, monolithic networks at any tasks?

Modular/Multiple Neural networks (MNNs) revolve around training smaller, independent networks that can feed into each other or another higher network. In principle, the hierarchical organization ...

Is a calculus or ML approach to varying learning rate as a function of loss and epoch been investigated?

Many have examined the idea of modifying learning rate at discrete times during the training of an artificial network using conventional back propagation. The goals of such work have been a balance ...

Neural networks of arbitrary/general topology?

Usually neural networks consist from layers, but is there research effort that tries to investigate more general topologies for connections among neurals, e.g. arbitrary directed acyclic graphs (DAGs)....

Can layers of deep neural networks be seen as Hopfield networks?

Hopfield networks are able to store a vector and retrieve it starting from a noisy version of it. They do so setting weights in order to minimize the energy function when all neurons are set equal to ...

Number of input variables for a cellular automaton (was: Squares or hexagonal?)

A cellular automaton is a state machine that is controlled by external input. The input is given by geometrical space around a cell. In a square matrix, each automaton gets input from 4 surrounding ...
