support vector machine中文 calculator

The Support Vector Machine (SVM) Calculator accepts gene expression values from log 2 normalized microarray data and copy number values as integers. It can also accept qRT-PCR data, but equal width binning is necessary for comparison to the training set (paclitaxel and gemcitabine models only). SVMs were trained for paclitaxel and gemcitabine in Dorman et al. SVMs for doxorubicin, epirubicin

    A figure for geometric margin can be shown: It shows a vector w also called support vector which is perpendicular to the boundary line, which is always true. To prove this, let’s take any two points on the line, x i, x j, i ≠ j. Since two points are on the line, by definition, we have: w T x i + b = w T x j + b = 0

    Support Vector Machine algorithms are not scale invariant, so it is highly recommended to scale your data. For example, scale each attribute on the input vector X to [0,1] or [-1,+1], or standardize it to have mean 0 and variance 1. Note that the same scaling must be applied to the test vector to obtain meaningful results

    A support vector machine (SVM) is a supervised learning algorithm used for many classification and regression problems , including signal processing medical applications, natural language processing, and speech and image recognition.. The objective of the SVM algorithm is to find a hyperplane that, to the best degree possible, separates data points of one class from those of another class
