Learning Latent Process from High-Dimensional Event Sequences via Efficient Sampling

Neural Information Processing Systems

There are plenty of previous studies targeting the problem from different aspects. For temporal point process, agreat number of works [3, 13, 15, 16, 28] attempt to model the intensify function from statistic views, and recent studies harness deep recurrent model [24], generative adversarial network [23] and reinforcement learning [19, 18] to learn the temporal process. These researches mainly focus on one-dimension eventsequences where eacheventpossesses thesame marker.






The Limits of Post-Selection Generalization

Neural Information Processing Systems

A recent line of work initiated by Dworket al. [9] posed the question: Can we designgeneralpurpose algorithms for ensuring generalization in the presence of post-selection?

Unfortunately,the per-iteration cost of maintaining this adaptivedistribution for gradient estimation is more than calculating the full gradient itself, which we call the chicken-and-the-egg loop. As a result, the false impression of faster convergence in iterations, inreality,leads to slower convergence in time.
