LinearRegression(*, fit_intercept=True, normalize=False, copy_X=True, n_jobs=None, positive=False) [source] ¶ Ordinary least squares Linear Regression. n_jobs is an integer, specifying the maximum number of concurrently running workers. If 1 is given, no joblib parallelism is used at all, which is useful for debugging.

The number of parallel jobs to run for neighbors search. None means 1 unless in a joblib.parallel_backend context. -1 means using all processors.

If a callable is passed, it should take arguments X, n_clusters and a random state and return an initialization. n_init int, default=10. Number of time the k-means algorithm will be run with different centroid seeds. The final results will be the best output of n_init consecutive runs in terms of inertia. max_iter int, default=300 SVM classifiers don't scale so easily.

By default, it will run for one hour. n_jobs (Optional) – Number of parallel threads used to run xgboost.

n_jobs int Returns y array of shape = [n_samples, n_classes] or If n_jobs was set to a value higher than one, the data is copied for each point in the grid (and not n_jobs times). This is done for efficiency reasons if individual jobs take very little time, but may raise errors if the dataset is large and not enough memory is available. A workaround in this case is to set pre_dispatch. 2020-09-12 · Importantly, you should set the “n_jobs” argument to the number of cores in your system, e.g. 8 if you have 8 cores. The optimization process will run for as long as you allow, measure in minutes.

My conda setup: n_jobs (int, optional (default=-1)) – Number of parallel threads. **kwargs is not supported in sklearn, it may cause unexpected issues. Note. To use auto-sklearn V2, you can use following code: TIME_BUDGET= 60 automl = autosklearn.experimental.askl2.AutoSklearn2Classifier( time_left_for_this_task=TIME_BUDGET, n_jobs=-1, metric=autosklearn.metrics.roc_auc, ) Auto-sklearn for regression . The second type of problem which auto-sklearn can solve is regression. If n_jobs was set to a value higher than one, the data is copied for each point in the grid (and not n_jobs times).
