Learning Latent Temporal Structure for Complex Event Detection

As a reaction to this complexity, we designed a new abstraction that allows us to express the simple computa- tions we were trying to perform but hides the messy de- tails of parallelization, fault-tolerance, data distribution and load balancing in a library. Our abstraction is in- spired by the map and reduce primitives present in Lisp and many other functional languages. We realized that most of our computations involved applying a map op- eration to each logical “record” in our input in order to compute a set of intermediate key/value pairs, and then applying a reduce operation to all the values that shared the same key, in order to combine the.
