Tensorflow Tutorial:

• Tensorflow is a programming framework used in deep learning
• The two main object classes in tensorflow are Tensors and Operators.
• When you code in tensorflow you have to take the following steps:
  • Create a graph containing Tensors (Variables, Placeholders …) and Operations (tf.matmul, tf.add, …)
  • Create a session
  • Initialize the session
  • Run the session to execute the graph
• You can execute the graph multiple times as you’ve seen in model()
• The backpropagation and optimization is automatically done when running the session on the “optimizer” object.
