Truncated svd for faster detection

WebThis article utilizes the concept of truncated singular value decomposition (SVD) for detecting hate content on the ETHOS (Binary-Label) dataset. Compared with the baseline results, our framework has performed better in various machine learning algorithms like SVM, Logistic Regression, XGBoost, and Random Forest. WebJun 30, 2024 · With that in mind, you could use MATLAB's svds function as follows: [U,S,V] = svds (A,k); Ainv = V*diag (1./diag (S))*U'; Here k refers to the rank and svds computes only a subset of singular values and vectors. Due to the use of Krylov subspace methods, it also allows to limit other factors such as subspace-dimension. Share.
