Is this the right approach to preprocessing data for artificial neural-networks?

Here is what I'd do: Whats the right way to ordinal encode data? If there's a natural ordering to the data, which is your case, then it's fine to map the data to a non-decreasing sequence of numbers. …

How Many Hidden Units in an LSTM?

I'm not sure about what you are referring to when you say "number of hidden units", but I will assume that it's the dimension of the hidden vector $h_t \in \mathbb{R}^N$ in this definition of an LSTM. …

What architecture would be best to match images of torn pieces of tapes?

Why not try a Siamese network architecture? This architecture is used to compute the similarity between two inputs by applying the same neural network $f$ to two pairs of inputs $(X_b, X_p)$ and $(X_b …

What is the difference between CNN-LSTM and RNN?

An LSTM is a specific type of RNN. So let's just focus on the CNN part in CNN-LSTM. What's the difference between a plain RNN and a CNN-RNN, (more generally called convolutional RNN or ConvRNN)? The e …

How to represent multi-label colours in one-hot encoding?

If the order of words doesn't matter in the description of the stone, you could use a bag of words model. You don't need the hashing trick because there's likely only a small fixed set of words used t …
