How can I use neural networks for detecting TV channel logos in video frames?
To perform image recognition you have to find a way to represent an image with certain features.
One of the defining characteristics of a good image recognition algorithm are it's ability to detect ...

Is there a neural network in the literature that predicts the next game state based on the current state and the action?
This is a whole sub-field of reinforcement learning known as model-based reinforcement learning. The idea in model based RL is to learn the mapping from current state/action to next state in order to ...

Which neural network can approximate the function $y = x^2 + b$?
$f(x) = x^2 + b$ is a polynomial (more precisely, a parabola) so it is continuous, thus, a neural network (with at least one hidden layer) should be able to approximate that function (given the ...
