Researchers have introduced Deflation-Free Sparse Optimal Scoring (DFSOS), a new method for feature selection in high-dimensional data. Unlike traditional sequential approaches that can propagate errors, DFSOS estimates discriminant vectors simultaneously using an orthogonality constraint. This novel technique combines Bregman iteration with constrained optimization, breaking down the problem into manageable sub-steps. Experiments show DFSOS performs comparably to or better than existing methods on synthetic and real-world time series data. AI
