Tangent Space Least Adaptive Clustering

2021-06-13 · ICML Workshop URL 2021 7 · James Buenfil, Samson J Koelle, Marina Meila

The biasing of dynamical simulations along collective variables uncovered by unsupervised learning has become a standard approach in analysis of molecular systems. However, despite parallels with reinforcement learning (RL), state of the art RL methods have yet to reach the molecular dynamics community. The interaction between unsupervised learning, dynamical simulations, and RL is therefore a promising area of research. We introduce a method for enhanced sampling that uses nonlinear geometry estimated by an unsupervised learning algorithm in a reinforcement-learning enhanced sampler. We give theoretical background justifying this method, and show results on data.

Subspace Clustering via Tangent Cones

2017-12-01 · NeurIPS 2017 12 · Amin Jalali, Rebecca Willett

Given samples lying on any of a number of subspaces, subspace clustering is the task of grouping the samples based on the their corresponding subspaces. Many subspace clustering methods operate by assigning a measure of …

Delving into Spectral Clustering with Vision-Language Representations

2026-02-10 · Bo Peng, Yuanwei Hu, Bo Liu, Ling Chen 외 arxiv

Spectral clustering is known as a powerful technique in unsupervised data analysis. The vast majority of approaches to spectral clustering are driven by a single modality, leaving the rich information in multi-modal repr…

Optimized Kernel-based Projection Space of Riemannian Manifolds
