In pattern recognition and machine learning, a feature vector is an n-dimensional vector of numerical features that represent some object. Many algorithms in machine learning require a numerical representation of objects, since such representations facilitate processing and statistical analysis. When … See more In machine learning and pattern recognition, a feature is an individual measurable property or characteristic of a phenomenon. Choosing informative, discriminating and independent features is a crucial element of … See more In character recognition, features may include histograms counting the number of black pixels along horizontal and vertical directions, number … See more • Covariate • Dimensionality reduction • Feature engineering • Hashing trick See more A numeric feature can be conveniently described by a feature vector. One way to achieve binary classification is using a linear predictor function (related to the perceptron) with a feature vector as input. The method consists of calculating the scalar product between … See more The initial set of raw features can be redundant and too large to be managed. Therefore, a preliminary step in many applications of machine learning and pattern recognition consists of selecting a subset of features, or constructing a new and reduced set of … See more Web3.1 Feature Encoding Assume Xis an N-dimensional vector space (eg. RN), where each xis a feature vector. We can then think of x= [x 1;x 2:::x n] as a point in X. We can encode a name in the badges game by encoding its characters, where each group of features represents a character. In each group we want 26 2+1
