Embeddings

An embedding of a vector is another vector in a smaller dimensional space

• Manage sparse data
• Make machine learning models that use sparse data consume less memory and train faster
• Reduce dimensionality
• Increase model generalization
• Cluster observations

Similarity Property

Custom Estimator

• Go beyond canned estimators
• Write a custom estimator
• Gain control over model functions
• Incorporate Keras models into Estimator

Model Function

• Keras is a high-level deep neural network library that support multiple backends
