Introduction The problem of classification consists in assigning an observation to the category it belongs. That means, for instance, taking a picture of a handwritten digit and correctly classifying which digit (0-9) it is, matching pictures of faces to whom they belong or classifying the sentiment in a text. In general, when dealing with classification we use supervised learning (when we have an annotated training set from which we can learn our model - as we did up until this point).
Introduction TensorFlow™ is an open source machine learning library for Python (and C++) initially developed by the Google Brain Team for research and released under the Apache 2.0 Open Source License on November 9th, 2015 . It is currently used by Google in their speech recognition, Gmail, Google Photos, Search services and recently adopted by the DeepMind team . Features Though TensorFlow was built with deep learning in mind, its framework is general enough so that we can also implement clustering methods, graphical models, optimization problems and others.
