Approximately Optimal Risk-Averse Routing Policies via Adaptive Discretization
Mitigating risk in decision-making has been a longstanding problem. Due to the mathematical challenge of its nonlinear nature, especially in adaptive decisionmaking problems, fin...

Topical Word Embeddings
Most word embedding models typically represent each word using a single vector, which makes these models indiscriminative for ubiquitous homonymy and polysemy. In order to enhance...

An Entorhinal-Hippocampal Model for Simultaneous Cognitive Map Building
Hippocampal place cells and entorhinal grid cells have been hypothesized to be able to form map-like spatial representation of the environment, namely cognitive map. In most prior...

Visualization Techniques for Topic Model Checking
Topic models remain a black box both for modelers and for end users in many respects. From the modelers’ perspective, many decisions must be made which lack clear rationales and...
