singa-incubating-0.2.0 Release Notes

SINGA is a general distributed deep learning platform for training big deep learning models over large datasets. It is designed with an intuitive programming model based on the layer abstraction. SINGA supports a wide variety of popular deep learning models.

This release includes the following major features:

• Training on GPU enables training of complex models on a single node with multiple GPU cards.
• Hybrid neural net partitioning supports data and model parallelism at the same time.
• Python wrapper makes it easy to configure the job, including neural net and SGD algorithm.
• RNN model and BPTT algorithm are implemented to support applications based on RNN models, e.g., GRU.
• Cloud software integration includes Mesos, Docker and HDFS.
