Faster kNN Classification Algorithm in Python - Stack Overflow

Webb11 jan. 2024 · K-nearest neighbor or K-NN algorithm basically creates an imaginary boundary to classify the data. When new data points come in, the algorithm will try to predict that to the nearest of the boundary line. Therefore, larger k value means smother curves of separation resulting in less complex models. Whereas, smaller k value tends to … Webbknn 算法简单易行，在很多情况下都取得不错的效果。在一定条件下，knn的错误率不会超过贝叶斯分类方法的2倍[9]。当数据量足够大时，knn算法的准确率趋于贝叶斯。在一些应用领域，knn算法的准确率要高于svm，knn算法特别适用于多模分类和多标签分类问题[10]。 ph smcl
