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 WebFeb 11, 2024 · Once we assign numeric values, we create a binary vector that represents our numerical values. In this case, our vector will have 2 as its length since we have 2 values. Thus, the red value can be represented with the binary vector [1,0], and the blue value will be represented as [0,1]. Why use one hot encoding?
