Hi Ankit, thanks for your interest in participating in GSoC with us. Its hard to tell based on your linked information–it needs a bit of fleshing out. Pathfinder is one potential beneficiary of this work, but it could be applied more broadly. We are looking for an improved minibatch implementation that includes handling streaming data, so experience with both of these is going to be helpful.
Keep in mind that the submission deadline is tomorrow, so there isn’t a great deal of time. Let us know if you need us to look at a draft at any point today.
