Representation Learning via Variational Bayesian Networks

no code implementations28 Jun 2023 Oren Barkan, Avi Caciularu, Idan Rejwan, Ori Katz, Jonathan Weill, Itzik Malkiel, Noam Koenigstein

We present Variational Bayesian Network (VBN) - a novel Bayesian entity representation learning model that utilizes hierarchical and relational side information and is particularly useful for modeling entities in the ``long-tail'', where the data is scarce.

On the Evolution of Word Order

no code implementations RANLP 2021 Idan Rejwan, Avi Caciularu

We also show that adding information to the sentence, such as case markers and noun-verb distinction, reduces the need for fixed word order, in accordance with the typological findings.

Top-k Combinatorial Bandits with Full-Bandit Feedback

no code implementations28 May 2019 Idan Rejwan, Yishay Mansour

Top-k Combinatorial Bandits generalize multi-armed bandits, where at each round any subset of $k$ out of $n$ arms may be chosen and the sum of the rewards is gained.
