This configuration argument allows you to specify the number of cores to use for the task. The default is None, which will use a single core. The training of the individual classifiers can also be set to run in parallel using the n_jobs parameter. Alternatively, I would also consider using a Random Forest classifier - it supports multi-class classification natively, it is fast and gives pretty good probability estimates when min_samples_leaf is … sklearn.ensemble.AdaBoostClassifier¶ class sklearn.ensemble.AdaBoostClassifier (base_estimator = None, *, n_estimators = 50, learning_rate = 1.0, algorithm = 'SAMME.R', random_state = None) [source] ¶. An AdaBoost classifier. An AdaBoost [1] classifier is a meta-estimator that begins by fitting a classifier on the original dataset and then fits additional copies of the classifier on the same sklearn.tree.DecisionTreeClassifier.

The issue is about: The great majority of the docstrings for n_jobs is something like "number of jobs to run in parallel". Description I noticed that cluster.KMeans gives a slightly different result depending on if n_jobs=1 or n_jobs>1. Steps/Code to Reproduce Below is the code I used to run the same KMeans clustering on a varying number of jobs.

nthreads should be IMHO as well called n_jobs to follow sklearn conventions, but currently it is not. 2020-09-19 n_jobs (Optional) – Number of parallel threads used to run xgboost. When used with other Scikit-Learn algorithms like grid search, you may choose which algorithm to parallelize and balance the threads. Creating thread contention will significantly slow down both algorithms.

For more details on the use of joblib and its interactions with scikit-learn, please refer to our parallelism notes . In most estimators on scikit-learn, there is an n_jobs parameter in fit/predict methods for creating parallel jobs using joblib.I noticed that setting it to -1 creates just 1 Python process and maxes out the cores, causing CPU usage to hit 2500 % on top. This is quite different from setting it to some positive integer >1, which creates multiple Python processes at ~100 % usage. sklearn.neighbors.KNeighborsClassifier n_jobs int, default=None.
