How to use the tensorflow.Variable function in tensorflow Snyk

WebA sampled softmax function is like a regular softmax but randomly selects a given number of 'negative' samples. This is difference than NCE Loss, which doesn't use a softmax at all, it uses a logistic binary classifier for the context/labels. In NLP, 'Negative Sampling' basically refers to the NCE-based approach. More details here
