Added a tolerance parameter to tSNE and implemented an early-stopping mechanism based on the L1 norm of the difference. Furthermore I also added a test case, whose setup guarantees that the early-stopping mechanism is triggered. Without early-stopping, tSNE always runs 1000 iterations (based on the default parameter value). More often than not, this leads to redundant iterations, where changes are minimal. This mechanism is a good addition as it adds a dimension of flexibility to the algorithm. -- This is an automated message from the Apache Git Service.
