A Gated MLP Architecture for Learning Topological Dependencies in Spatio-Temporal Graphs

no code implementations29 Jan 2024 Yun Young Choi, Minho Lee, Sun Woo Park, Seunghwan Lee, Joohwan Ko

The Cy2Mixer is composed of three blocks based on MLPs: A message-passing block for encapsulating spatial information, a cycle message-passing block for enriching topological information through cyclic subgraphs, and a temporal block for capturing temporal properties.

Provably Scalable Black-Box Variational Inference with Structured Variational Families

no code implementations19 Jan 2024 Joohwan Ko, Kyurae Kim, Woo Chang Kim, Jacob R. Gardner

In fact, recent computational complexity results for BBVI have established that full-rank variational families scale poorly with the dimensionality of the problem compared to e. g. mean field families.

Modeling Choice via Self-Attention

no code implementations11 Nov 2023 Joohwan Ko, Andrew A. Li

Naturally, accurate estimation of these models from data is a critical step in the application of these optimization problems in practice.

Learning to Scale Logits for Temperature-Conditional GFlowNets

1 code implementation4 Oct 2023 Minsu Kim, Joohwan Ko, Taeyoung Yun, Dinghuai Zhang, Ling Pan, Woochang Kim, Jinkyoo Park, Emmanuel Bengio, Yoshua Bengio

We find that the challenge is greatly reduced if a learned function of the temperature is used to scale the policy's logits directly.
