|[PCA](https://github.com/Cheng-Lin-Li/MachineLearning/tree/master/PCA)|An algorithm for dimension reductions. PCA is a statistical technique, via orthogonal transformation, convert dataset that some of them may correlated to a new data space that is linearly uncorrelated set of values. This new set of data call principal components. PCA is sensitive to the relative scaling of the original variables, so before applying PCA, data pre-processing step is very important and we should always do. Mean normalization (xi - mean of the feature) or feature scaling (xi - mean)/max(xi) or (xi - mean)/(Standard deviation of x) then replace xi by the new value for each feature are required. |[Specification](https://github.com/Cheng-Lin-Li/MachineLearning/blob/master/PCA/INF552-TechnicalSpecification-PCA_FastMap-%5B1.0%5D-%5B20161011%5D.pdf) and [Source Code](https://github.com/Cheng-Lin-Li/MachineLearning/blob/master/PCA/PCA.py)|

|Linear regression|Linear regression is a linear modeling to describe the relation between a scalar dependent variable y and one or more independent variables, X.|[Source Code](https://github.com/Cheng-Lin-Li/MachineLearning/blob/master/scikit-learn/LinearRegression/sklearn-LinearRegression.py)|

|Logistic regression|logit regression. It is different to regression analysis. A linear probability classifier model to categorize random variable Y being 0 or 1 by given experiment data. Assumes each of categorize are independent and irrelevant alternatives. The model p(y=1\|x, b, w) = sigmoid(g(x)) where g(x)=b+wTx. The sigmoid function = 1/1+e^(-a) where a = g(x).|[Source Code](https://github.com/Cheng-Lin-Li/MachineLearning/blob/master/scikit-learn/LogisticRegression/logistic_regression.py)|
