A new research paper by Yusong Zhu explores the problem of sparse recovery in statistics, focusing on the distinction between oblivious and adaptive models for variable selection. The study demonstrates a provable separation, showing that oblivious models can achieve optimal error guarantees with significantly fewer samples and in near-linear time compared to adaptive models. This finding contrasts with the standard L2 setting and suggests that partially-adaptive models may offer a middle ground with substantial variable selection guarantees. AI
