With our 16hour seminar you can learn how to develop and deploy neural networks to production using Google's open-source machine learning API for big data clusters.
Tensorflow is a numeric computation framework open-sourced by Google. From a system’s perspective, Tensorflow’s distinguishing feature is the ability to parallelize and distribute computations over thousands of CPUs and GPUs, making it suitable for deployments on large clusters. From a developer’s perspective TensorFlow makes life easy: install TF on your laptop in secs, write and test your code there, then copy to server. The same code runs on your laptop or your Android device or a massive cluster of thousands of nodes without modifications. Moreover, TF auto-differentiates all the functions it understands saving you hundreds of code lines and hours of debugging. All these are made possible by the simple principle of separating computation declaration from execution.
The course is an introduction to TF and computation graphs using TF’s Python API. Although introductory, the course covers a substantial breadth of TF’s concepts and tools with hands-on examples and exercises.
- Learn the basics of declarative computation (computation graphs).
- Learn how TF implements declarative computation.
- Learn how to implement basic neural networks for classification and regression tasks.
