This week I read upon GraphX, a distributed graph computation framework that unifies graph-parallel and data-parallel computation. Graph-parallel systems efficiently express iterative algorithms (by exploiting the static graph structure) but do not perform well on operations that require a more general view of the graph like operations that move data out of the graph. Data-parallel systems perform well on such tasks but directly implementing graph algorithms on data-parallel systems is inefficient due to complex joins and excessive data movement. This is the gap that GraphX fills in by allowing the same data to be viewed and operated upon both as a graph and as a table.
Let G = (V, E) be a graph where V = {1, ..., n} is the set of vertices and E is the set of m directed edges. Each directed edge is a tuple of the form (i, j) ∈ E where i ∈ V is the source vertex and j ∈ V is the target vertex. The vertex p

Topic
Introduction to Deep Learning with Keras
Description
Keras is a high-level neural networks library, written in Python and capable of running on top of either TensorFlow or Theano. It was developed with a focus on enabling fast experimentation. Being able to go from idea to result with the least possible delay is key to doing good research.
In the talk, I would introduce Keras and talk about how it can be used to accomplish workflows like image classfication and sequence modelling.
