Embeddings | Machine Learning Crash Course | Google Developers

Feb 10, 2020· An embedding is a relatively low-dimensional space into which you can translate high-dimensional vectors. Embeddings make it easier to do machine learning on large inputs like sparse vectors representing words. Ideally, an embedding captures some of the semantics of the input by placing semantically similar inputs close together in the embedding space.

Honing (metalworking) - Wikipedia

Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive grinding stone or grinding wheel against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but can also improve the surface finish.. Typical applications are the finishing of cylinders for internal combustion engines, air bearing ...
