<issue_start>username_0: I am currently searching for a supervised learning algorithm that can be used to predict the output given a large enough training set. Here's a simple example. Suppose the training dataset is `{[A=1, B=330, C=1358.238902], result=234.244378}` and the test dataset `{[A=893, B=34, C=293], result...

<issue_start>username_0: I've gone through several descriptions of CNNs online and they all leave out a crucial part as if it were trivial. A "volume" of neurons consists of several parallel layers ("feature maps"), each the result of convolving with a different kernel. Between volumes, there is usually a step where ...
