The goal of feature selection is to reduce... 4 min read · [learningmachine.hashnode.dev](https://learningmachine.hashnode.dev/sequential-feature-selection?utm_source=hashnode&utm_medium=feed) [Feb 23, 2023](https://hashnode.com/posts/sequential-feature-selection/63f7408ec6c46d4a13e3a118) ### [Dealing with missing data](https://learningmachine.hashnode.dev/dealing-with-missing-data?utm_source=hashnode&utm_medium=feed) import pandas as pd from io import StringIO import sys csv\_data = \\ '''A,B,C,D 1.0,2.0,3.0,4.0 5.0,6.0,,8.0 10.0,11.0,12.0,''' if (sys.version\_info < (3, 0)): csv\_data = unicode(csv\_data) df = pd.read\_csv(StringIO(csv\_data)) df.isnull().sum(... 1 min read · [learningmachine.hashnode.dev](https://learningmachine.hashnode.dev/dealing-with-missing-data?utm_source=hashnode&utm_medium=feed) [Feb 21, 2023](https://hashnode.com/posts/dealing-with-missing-data/63f4851d10de491e996baf6c) ### [K-nearest neighbors](https://learningmachine.hashnode.dev/k-nearest-neighbors?utm_source=hashnode&utm_medium=feed) KNN (K-Nearest Neighbors) algorithm is a machine learning algorithm used for both classification and regression tasks. It is a non-parametric and lazy learning algorithm, which means it doesn't make any assumptions about the underlying distribution o... 2 min read · [learningmachine.hashnode.dev](https://learningmachine.hashnode.dev/k-nearest-neighbors?utm_source=hashnode&utm_medium=feed) [Feb 20, 2023](https://hashnode.com/posts/k-nearest-neighbors/63f3372073b3ad2af6ada9a3) ### [Bootstrap](https://learningmachine.hashnode.dev/bootstrap?utm_source=hashnode&utm_medium=feed) Bootstrap is a statistical resampling method used to estimate the sampling distribution of a statistic or to compute confidence intervals for a population parameter.
