Prominent Roles of Conditionally Invariant Components in Domain Adaptation: Theory and Algorithms

no code implementations19 Sep 2023 Keru Wu, Yuansi Chen, Wooseok Ha, Bin Yu

Domain adaptation (DA) is a statistical learning problem that arises when the distribution of the source data used to train a model differs from that of the target data used to evaluate the model.

Minimax Mixing Time of the Metropolis-Adjusted Langevin Algorithm for Log-Concave Sampling

no code implementations27 Sep 2021 Keru Wu, Scott Schmidler, Yuansi Chen

First, for a $d$-dimensional log-concave density with condition number $\kappa$, we show that MALA with a warm start mixes in $\tilde O(\kappa \sqrt{d})$ iterations up to logarithmic factors.
