WebClassifier implementing a vote among neighbors within a given radius. Parameters: radius – Range of parameter space to use by default for radius_neighbors () queries. weights – Weight function used in prediction. Possible values: ’uniform’: uniform weights. All points in each neighborhood are weighted equally. WebWe first describe the radius neighbors classifier (r-N) and show that its accuracy under differential privacy can be greatly improved by a non-trivial sensitivity analysis. Then, for k-NN classification, we build algorithms that convert k-NN classifiers to r-N classifiers. We experimentally evaluate the accuracy of both classifiers using ... stranded deep admin commands switch
