coefficient of determination

The coefficient of determination (also depicted as R^2) is a calculation of the proportion of the variance in the dependent variable (noted as y) which is explained by a linear regression model. The value of the coefficient of determination can be in the 0..1 range. The coefficient of determination can be calculated by using the ... Read more


A central processing unit (CPU) is a complex electronic circuit which performs all numerical, logic, IO and control computations inside a computer. There are generally two types of CPUs, ie reduced instruction set computers (RISC) and Complex Instruction Set Computers (CISC). There are also other similar circuits to a CPU, with a more specialized scope ... Read more

cross validation

In machine learning (ML), cross validation is a method in which the data scientists perform an evaluation of an ML model's performance on unlabelled data, i.e. data which the ML model has not seen before. In the method of cross validation, the data which is available in the dataset is split into multiple subsets. One ... Read more
