● sess.run(init)
Linear Classifier Example
● tf.SparseTensor()
● tf.constant)_
● tf.contrib.layers.sparse_column_with_hash
_bucket()
● tf.contrib.layers.real_valued_column()
● tf.contrib.learn.LinearClassifier()
○ default Ftrl optimizer will be used
○ https://www.tensorflow.org/api_docs/pytho

● m.fit()
● m.evaluate()
“An interface for expressing machine learning algorithms
and an implementation for executing such algorithms
A framework for creating ensemble algorithms for today’s most challenging
problems “ - Google Brain Team
6. K Mean Clustering
k-means clustering aims to partition n observations into k clusters in which each
observation belongs to the cluster with the nearest mean. [source: Wikipedia]
7. Linear Classifier
A linear classifier achieves this by making a classification decision based on the value of a linear
combination of the characteristics[wikipedia]
For a two-class classification problem, one can visualize the operation of a linear classifier as splitting a
high-dimensionalinput space with a hyperplane: all points on one side of the hyperplane are classified as
"yes", while the others are classified as "no".
