Distributed Non-Stochastic Experts [article]

Varun Kanade, Zhenming Liu, Bozidar Radunovic
2012 arXiv   pre-print
We consider the online distributed non-stochastic experts problem, where the distributed system consists of one coordinator node that is connected to k sites, and the sites are required to communicate  ...  The two extreme solutions to this problem are: (i) Full communication: This essentially simulates the non-distributed setting to obtain the optimal O(√((n)T)) regret bound at the cost of T communication  ...  distributed online non-stochastic experts setting.  ...

Stochastic-Expert Variational Autoencoder for Collaborative Filtering

Yoon-Sik Cho, Min-hwan Oh
2022 Proceedings of the ACM Web Conference 2022  
Our proposed stochastic expert framework is generic and adaptable to any VAE architecture.  ...  In our method, individual experts are sampled stochastically at each user-item interaction which can effectively utilize the variability among multiple experts.  ...  Mixture of Expert vs Stochastic Expert.  ...

The True Expert Knows Which Question Should be Asked

Eddie Dekel, Yossi Feinberg
2004 Social Science Research Network  
We suggest a test for discovering whether a potential expert is informed of the distribution of a stochastic process.  ...  In a non-Bayesian non-parametric setting, the expert is asked to make a prediction which is tested against a single realization of the stochastic process.  ...  A decision maker named Alice is trying to decide whether Bob, who is potentially an expert, is informed about the distribution governing a stochastic process.  ...

Predicting distributions with Linearizing Belief Networks [article]

Yann N. Dauphin, David Grangier
2016 arXiv   pre-print
Conditional belief networks introduce stochastic binary variables in neural networks.  ...  A LBN decomposes into a deep linear network where each linear unit can be turned on or off by non-deterministic binary latent units.  ...  This yields a mixture of non-linear neural networks gated by a stochastic non-linear neural network.  ...

A prequential test for exchangeable theories

Alvaro Sandroni, Eran Shmaya

Stochastic population forecasts based on conditional expert opinions

F. C. Billari, R. Graziani, E. Melilli
2011 Journal of the Royal Statistical Society: Series A (Statistics in Society)  
The full probability distribution of population forecasts is specified by starting from expert opinions on the future development of demographic components.  ...  The paper develops and applies an expert-based stochastic population forecasting method, which can also be used to obtain a probabilistic version of scenario-based official forecasts.  ...  Traditional population projections are, in fact, non-stochastic expert-based 'what if ?' scenarios.  ...

Lifelong Learning with Branching Experts

Yi-Shan Wu, Yi-Te Hong, Chi-Jen Lu
2021 Asian Conference on Machine Learning  
While it was known that the adversarial branching experts problem is strictly harder than the non-branching one, the stochastic branching experts problem is in fact no harder.  ...  Furthermore, we prove a regret lower bound which shows that in the lifelong learning scenario, the case with branching experts now becomes strictly harder than the non-branching case in the stochastic  ...  In the paper (Luo and Schapire, 2015) , for the non-branching case, the AdaNormal-Hedge.TV algorithm has small adaptive regrets for both adversarial and stochastic setting.  ...

Learning stochastic finite automata from experts [chapter]

Colin de la Higuera
1998 Lecture Notes in Computer Science  
We present in this paper a new learning problem called learning distributions from experts. In the case we study the experts are stochastic deterministic finite automata (sdfa).  ...  This is intended to model the situation where the data is not generated automatically, but in an order dependent of its probability, as would be the case with the data presented by a human expert.  ...  Perhaps even a second expert can help : one can use the amount of times experts agree on the ordering of specific strings as a compatibility test.  ...
