Standard DNN Random Random None Train featurization and output jointly Headless DNN Learn using another task Separate ML algorithm Use the features learned on a related task Use the features to train a separate classifier Fine Tune DNN Learn using another task Random Use and fine tune features learned on a related task Train featurization and output jointly with a small learning rate Multi-Task DNN Random Random Learned features need to solve many related tasks Share a featurization network across both tasks. Train all networks jointly with a loss function (sum of individual task loss function)

- 26. Distributed Training Architecture Data Parallelism Model Parallelism 1. Parallel training on different machines 2. Update the parameter server synchronously/asynchronously 3. Refresh the local model with new parameters, go to 1 and repeat 1. The global model is partitioned into K sub-models without overlap. 2. The sub-models are distributed over K local workers and serve as their local models. 3. In each mini-batch, the local workers compute the gradients of the local weights by back propagation.

- 30. Using Spark for Machine Learning • User needs to write lots of “glue” code to prepare features for ML algorithms. • Coerce types and data layout to that what’s expected by learner • Use different conventions for different learners • Lack of domain-specific libraries: computer vision or text analytics… • Latest: Image Data Support in Apache Spark 2.3 https://blogs.technet.microsoft.com/machinelearning/2018/03/05/image- data-support-in-apache-spark/ • Limited capabilities for model evaluation & model management
