5 .Unified Big Data Analytics Platform
6 .Chasm b/w Deep Learning and Big Data Communities The Chasm Deep learning experts Real-world users (big data users, data scientists, analysts, etc.)
7 . Large-Scale Image Recognition https://software.intel.com/en-us/articles/building-large-scale-image-feature-extraction- with-bigdl-at-jdcom
8 .Standard Spark jobs • No changes to the Spark or Hadoop clusters needed Data parallel • Each Spark task runs the same model on a subset of the data (batch) “Zero” code change • Directly support TensorFlow, Keras and Caffe Model Seamlessly deployed on production big data clusters • Only need to install on driver node.
