Tensorflow is an open-sourced library that facilitates large-scale machine learning and numerical computation. It is python-friendly and was created by the Google Brain Team in the year 2015. It eases the process of acquiring data, training models, serving predictions, and refining future results. It is used both for machine learning as well as deep learning. Tensorflow is a cross-platform tool. It can run on iOS and Android devices, CPUs or GPU’s and even TPU’s( Tensorflow Processing Units ). Tensorflow enables developers to make dataflow graphs that depict the flow of data on a graph. Tensorflow operates mostly in the Python language which is fairly simple to learn and work on. However, the actual math operations are not performed in Python. The libraries of transformations that are available through Tensorflow are written as high-performance C++ binaries.
