+<br>'''Deep Speech'''
+* Re-wrote deep learning training algorithm (Adam optimization) to work across multiple GPU's
+* Integrated CPU based CTC algorithm into the neural network
+* Benchmarked GPU based CTC algorithm vs CPU based CTC algorithm looking at execution time and validation error
+** GPU algorithm much better - less validation error, less time variance and we don’t have to move data between CPU and GPU memory.
+* Wrote code to periodically serialize the model to disk while training to allow for archiving performant models
+* Started writing the multi-threaded data loading code for the 300 hour TED data corpus

-* Platform
+* General agreement in the team to focus on a software Dev Kit first.
-** Team reviewing the common blocks & frameworks needed for each "track-1" product as they get defined/scoped.
+** Part 1 - Start cataloguing a “hub” of components & utilities that we already have on deck within CD teams (see examples in link below).
-** Assessing options (& pros/cons) for OTA framework, security policies, build systems etc. Keeping generic to benefit all products.
+** Part 2 - Add product specific developer framework components as we learn about each track-1 product's developer involvement.
-** Weekly Notes: https://docs.google.com/document/d/1yo1AtuozukgfkZwzO745LdEsB1fdZrEWoIYr8F9eydo/edit#heading=h.qgtmzupjdx35
+* Expect 1st devkit (for sensorweb & other products) around Feb'2017. Schedule of milestones being built.
