| Issue | #Downvotes for this reason | By |
|---|
| algorithm | default: "auto" | |
| leaf_size | Leaf size passed to BallTree or KDTree. This can affect the speed of the construction and query, as well as the memory required to store the tree. The optimal value depends on the nature of the problem | default: 30 |
| metric | Metric to use for distance computation. Default is "minkowski", which
results in the standard Euclidean distance when p = 2. See the
documentation of `scipy.spatial.distance
| default: "minkowski" |
| metric_params | Additional keyword arguments for the metric function | default: null |
| n_jobs | The number of parallel jobs to run for neighbors search
``None`` means 1 unless in a :obj:`joblib.parallel_backend` context
``-1`` means using all processors. See :term:`Glossary | default: null |
| n_neighbors | Number of neighbors to use by default for :meth:`kneighbors` queries weights : {'uniform', 'distance'}, callable or None, default='uniform' Weight function used in prediction. Possible values: - 'uniform' : uniform weights. All points in each neighborhood are weighted equally - 'distance' : weight points by the inverse of their distance in this case, closer neighbors of a query point will have a greater influence than neighbors which are further away - [callable] : a user-defined function which accepts an array of distances, and returns an array of the same shape containing the weights Refer to the example entitled :ref:`sphx_glr_auto_examples_neighbors_plot_classification.py` showing the impact of the `weights` parameter on the decision boundary algorithm : {'auto', 'ball_tree', 'kd_tree', 'brute'}, default='auto' Algorithm used to compute the nearest neighbors: - 'ball_tree' will use :class:`BallTree` - 'kd_tree' will use :c... | default: 10 |
| p | Power parameter for the Minkowski metric. When p = 1, this is equivalent to using manhattan_distance (l1), and euclidean_distance (l2) for p = 2 For arbitrary p, minkowski_distance (l_p) is used. This parameter is expected to be positive | default: 2 |
| weights | default: "uniform" |
