We use a neural network to parametrize the smooth vector field and a recursive neural network (RNN) for approximating the solution of the ODE.

The task is often cast as a structured output problem on an exponentially large output-space, which is typically modeled by a discrete probabilistic model.

The Power of Asymmetry in Binary Hashing

1 code implementation • NeurIPS 2013 • Behnam Neyshabur, Payman Yadollahpour, Yury Makarychev, Ruslan Salakhutdinov, Nathan Srebro

When approximating binary similarity using the hamming distance between short binary hashes, we show that even if the similarity is symmetric, we can have shorter and more accurate hashes by using two distinct code maps.
