Dimension-Adaptive Batched Lipschitz Narrowing Without Knowing the Zooming Dimension
Yasong Feng
The Appropriately Combined Edge-length (ACE) sequence in A-BLiN depends on the zooming dimension . This note removes that dependence. The next edge length is selected from the…
From Random Search to Bandit Learning in Metric Measure Spaces
Chuying Han, Yasong Feng, Tianyu Wang
Random Search is one of the most widely-used method for Hyperparameter Optimization, and is critical to the success of deep learning models. Despite its astonishing performance, li…
A Lipschitz Bandits Approach for Continuous Hyperparameter Optimization
Yasong Feng, Weijian Luo, Yimin Huang +1
One of the most critical problems in machine learning is HyperParameter Optimization (HPO), since choice of hyperparameters has a significant impact on final model performance. Alt…
Stochastic Zeroth Order Gradient and Hessian Estimators: Variance Reduction and Refined Bias Bounds
Yasong Feng, Tianyu Wang
We study stochastic zeroth order gradient and Hessian estimators for real-valued functions in . We show that, via taking finite difference along random orthogonal dir…
Lipschitz Bandits with Batched Feedback
Yasong Feng, Zengfeng Huang, Tianyu Wang
In this paper, we study Lipschitz bandit problems with batched feedback, where the expected reward is Lipschitz and the reward observations are communicated to the player in batche…
