Working With Sparse Features In Machine Learning Models

WebAug 12, 2024 · The big difference in the binary features is the fact that 0 1 = 0, which binds the entire product to 0. Whilst 0 0 = 1 and 1 1, which results in a dimension/feature whose value does not matter for our transformation. P.S. I prefer physics notation for vectors, a component of a vector is x but a full vector is x → instead of x. WebThese features can result in issues in machine learning models like overfitting, inaccurate feature importances, and high variance. It is recommended that sparse features should be pre-processed by methods like feature hashing or removing the feature to reduce the negative impacts on the results. tsv thurnau
