Tensorflow now gets the value of a, and b which it uses to compute the value of c, so it can compute the value of d. NET does not support DNN GPU acceleration, but support will likely be added in future releases. The edges represent tensors, a tensor representing an n-dimensional array. I haven't researched text summarization more after writing this article. The best loss I got was 0. a rule w*x without explicit threshold). When a cluster is started, it launches the TensorFlow workers and parameter servers (potentially on different hosts). As a Machine Learning engineer, on the other hand, your final “output” is working software (not the analyses or visualizations that you may have to create along the way), and your “audience” for this output often consists of other software components that run autonomously with minimal human supervision.
