New AFA-BANDIT framework offers provably near-optimal online classification

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced AFA-BANDIT, a novel framework for online multi-feature classification that addresses budget constraints. Unlike previous methods, AFA-BANDIT formulates the problem as a combinatorial Bandits with Knapsacks (BwK) problem, offering a provably near-optimal approach. The proposed LP-Chain variant efficiently searches for feature subsets, demonstrating superior performance and scalability compared to existing deep RL-based and HEDGE-based baselines on synthetic data.

    AFA-BANDIT: Provably Near-Optimal Online Multi-Feature Classification Under Budget Constraints

    arXiv:2610.07615v1 Announce Type: new Abstract: Active Feature Acquisition (AFA) is a classification problem in which an agent decides which costly features to acquire before predicting each sample's label. Unlike batch AFA, which trains a fixed policy and classifier offline on f…
