WebWithin machine learning, logistic regression belongs to the family of supervised machine learning models. It is also considered a discriminative model, which means that it attempts to distinguish between classes (or categories). Unlike a generative algorithm, such as naïve bayes, it cannot, as the name implies, generate information, such as an image, of the …

WebNov 14, 2024 · Curve fitting is a type of optimization that finds an optimal set of parameters for a defined function that best fits a given set of observations. Unlike supervised learning, curve fitting requires that you define the function that maps examples of inputs to outputs. The mapping function, also called the basis function can have any form you ... WebAug 9, 2024 · A sparse matrix is a matrix that is comprised of mostly zero values. Sparse matrices are distinct from matrices with mostly non-zero values, which are referred to as dense matrices. A matrix is sparse if many of its coefficients are zero. The interest in sparsity arises because its exploitation can lead to enormous computational savings and ...

The ideal value for r-square is 1. The closer the value of r-square to 1, the better is the model fitted. R-square …
WebNov 16, 2024 · In all that process, learning curves play a fundamental role. A learning curve is just a plot showing the progress over the experience of a specific metric related to learning during the training of a machine learning model. They are just a mathematical representation of the learning process. WebJun 16, 2024 · 3. fit computes the mean and stdev to be used for later scaling, note it's just a computation with no scaling done. transform uses the previously computed mean and stdev to scale the data (subtract mean from all values and then divide it by stdev). fit_transform does both at the same time. So you can do it with just 1 line of code.
