Why do we need both the validation set and test set?

I know that this has been asked a hundred times before, however, I was not able to find a question (and an answer) which actually answered what I wanted to know, respectively, which explained it in a ...

How to define an action space when an agent can take multiple sub-actions in a step?

I'm attempting to design an action space in OpenAI's gym and hitting the following roadblock. I've looked at this post which is closely related but subtly different. The environment I'm writing needs ...

How should I represent the input to a neural network for the games of tic-tac-toe, checkers or chess?

I've been reading a lot about TD-Gammon recently as I'm exploring options for AI in a video game I'm making. The video game is a turn-based positional sort of game, i.e. a "units", or game ...

Should I repeat lengthy deep learning experiments to average results ? How to decide how many times to repeat?

I am doing my MSc thesis on deep learning. My model takes many hours to train. Part of what I do is trying different parameters and settings hoping that they will achieve different results. But I ...

Given enough computational resources, do we currently have any algorithms which could achieve AI?

Hypothetically, assume that you have access to infinite computing power. Do we have designs for any brute-force algorithms that can find an AI capable of passing traditional tests (e.g. Turing, ...

When we are working on an AI project, does the context (academia, industry or competition) make the process different?

When we are working on an AI project, does the domain/context (academia, industry, or competition) make the process different? For example, I see in the competition most participants even winners use ...

How should I define the action space for a card game like Magic: The Gathering?

I'm trying to learn about reinforcement learning techniques. I have little background in machine learning from university, but never more than using a CNN on the MNIST database. My first project was ...
