textlogitp
Textlogitp is a term used to describe a family of text classification methods that apply logistic regression to text representations to produce calibrated probability estimates for class membership. The approach treats text data as a feature vector and uses a logistic function to map linear combinations of features to probability scores. Feature representations commonly used include bag-of-words, term frequency–inverse document frequency (TF-IDF), and various n-gram schemes, as well as dense embeddings when combined with a linear classifier. Textlogitp models may include L1 or L2 regularization to manage high dimensionality and improve generalization, and can be extended to multi-class classification via one-vs-rest or softmax formulations.
Software implementations typically offer pipelines that include preprocessing, feature extraction, and logistic training, with options for
Applications of textlogitp include sentiment analysis, topic labeling, spam filtering, and basic intent classification, particularly in
Advantages include straightforward interpretation of log-odds, probabilistic outputs, and efficient training and inference. Limitations involve reliance
