Deep neural networks for youtube recommendations. Unfreezing some layers in base network. Let's have a look at how to create an item profile. Neural Network Embedding Recommendation System. As the user provides more inputs or takes actions on those recommendations, the engine becomes more and more accurate. The model is compiled with the Adam optimizer (a variant on Stochastic Gradient Descent) which, during training, alters the embeddings to minimize the binary_crossentropy for this binary classification problem. Collaborative Filtering is the most common technique used when it comes to building intelligent recommender systems that can learn to give better recommendations as more information about users is collected.
