Principal component analysis (PCA) is a linear dimensionality reduction technique with applications in exploratory data analysis, visualization and data preprocessing. The data is linearly transformed onto a new coordinate system such that the directions (principal components) capturing the largest variation in the data can be easily identified.
In probability theory and statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable.The general form of its probability density function is = ().
Eigenvalues and eigenvectors. In linear algebra, an eigenvector (/ ˈaɪɡən -/ EYE-gən-) or characteristic vector is a vector that has its direction unchanged by a given linear transformation. More precisely, an eigenvector, , of a linear transformation, , is scaled by a constant factor, , when the linear transformation is applied to it: .
Betelgeuse is the brightest near-infrared source in the sky with a J band magnitude of −2.99; [95] only about 13% of the star's radiant energy is emitted as visible light. If human eyes were sensitive to radiation at all wavelengths, Betelgeuse would appear as the brightest star in the night sky.
Prism is the fourth studio album by American singer Katy Perry. It was released by Capitol Records on October 18, 2013. While the album was initially planned to be "darker" than her previous material, Prism ultimately became a prominently dance-inspired record.

Sir Oswald Ernald Mosley, 6th Baronet (16 November 1896 – 3 December 1980), was a British politician who rose to fame during the 1920s and 1930s when, having become disillusioned with mainstream politics, he turned to fascism. Mosley was the son of a baronet. He was a member of parliament and later founded and led the British Union of ...
Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, nitro, nitrus or nos, [4] is a chemical compound, an oxide of nitrogen with the formula N. 2O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. [5]
