Introduction to Anomaly Detection
Anomaly Detection (a.k.a Outlier Detection) is a process of detecting unexpected observations in specified datasets.
MSE vs MAE
MSE stands for mean squared error, MAE stands for mean absolute error. These are commonly used measurement in modelling.
Hessian Matrix
In mathematics, the Hessian matrix or Hessian is a square matrix of second-order partial derivatives of a scalar-valued function, or scalar field. It describes the local curvature of a function of many variables. Hessian Matrices are often used in optimization problems within Newton-Raphson's method.
Matrix Factorization
Matrix factorization is a class of algorithms used for recommendation systems in machine learning. Matrix factorization algorithms work by decomposing dimensionality. Commonly known matrix factorization algorithms are SVD and PCA.
LaTeX Math Equations
Having math equations in a report can be painful. Here are some LaTeX commands often used in scientific reports. I will try to keep this post updated.
