A Polynomial-time Algorithm for Online Sparse Linear Regression with Improved Regret Bound under Weaker Conditions

A new polynomial-time algorithm for online sparse linear regression has been introduced, addressing a previously NP-hard problem. This advancement is significant because it allows for more efficient predictions using only a subset of attributes, which can lead to better performance in various applications. The algorithm improves upon earlier methods by relaxing certain conditions, making it more applicable in real-world scenarios.
