Relative Positional Encoding for Transformers with Linear Complexity

ICML 2021oral

Recent advances in Transformer models allow for unprecedented sequence lengths, due to linear space and time complexity. In the meantime, relative positional encoding (RPE) was proposed as beneficial for classical Transformers and consists in exploiting lags instead of absolute positions for inferen…

Non-Asymptotic Analysis of Fractional Langevin Monte Carlo for Non-Convex Optimization

ICML 2019oral

Recent studies on diffusion-based sampling methods have shown that Langevin Monte Carlo (LMC) algorithms can be beneficial for non-convex optimization, and rigorous theoretical guarantees have been proven for both asymptotic and finite-time regimes. Algorithmically, LMC-based algorithms resemble the…

Asynchronous Stochastic Quasi-Newton MCMC for Non-Convex Optimization

ICML 2018oral

Recent studies have illustrated that stochastic gradient Markov Chain Monte Carlo techniques have a strong potential in non-convex optimization, where local and global convergence guarantees can be shown under certain conditions. By building up on this recent theory, in this study, we develop an asy…
