Sorted by: 2. The correct way of calling the parameters inside Pipeline is using double underscore like named_step__parameter_name .So the first thing I noticed is in this line: parameters = {'vect__ngram_range': [ (1, 1), (1, 2)],'tfidf__use_idf': (True, False),'clf__alpha': (1e-2, 1e-3) } You are calling vect__ngram_range but this ...

WebExamples: Comparison between grid search and successive halving. Successive Halving Iterations. 3.2.3.1. Choosing min_resources and the number of candidates¶. Beside factor, the two main parameters that influence the behaviour of a successive halving search are the min_resources parameter, and the number of candidates (or parameter … WebMar 24, 2024 · By default this should run a search for a grid of $5 \cdot 4 \cdot 3 = 60$ different parameter combinations. The default cross-validation is a 3-fold cv so the above code should train your model $60 \cdot 3 = 180$ times. By default GridSearch runs parallel on your processors, so depending on your hardware you should divide the number of ...
