On learning to rank tasks. Could it be that the input of the Siamese network is a vector, or should it be exclusively raw text?

I'm developing a method to document and query representation as concept vectors (bag-of-concepts). I want to train a machine learning model on ranking (learning to rank a task). So I have document ...

How to stabilize the training of a Conv-Siamese Neural Network if the results after different trainings vary relatively strongly?

I am training a neural network using MSE and ADAM optimizer. More precisely, a siamese architecture with a convolutional encoder and euclidean distance on top. I am using MSE because I have different ...

How to estimate the convolutional representation of a graph from its similarity to other graph convolutional representation?

Suppose we have two graphs A and B disconnected to each other (let's say 2-hops each), within a larger graph. If the convolutional representation of graph A is known, is it possible to estimate the ...

Is music/sound similarity comparison feasible on neural networks?

I wonder on the following concept: A given neural network gets two audio input (preferably music) and gives a real number between 0 and 1 which describes "similarity" between the second and the ...
