  • Learning with Linear Classifiers Course | eCornell

    2021-4-6 · In this course, you are introduced to and implement the Perceptron algorithm, a linear classifier that was developed at Cornell in 1957. Through the exploration of linear and logistic regression, you will learn to estimate probabilities that remain true to the problem settings. By using gradient descent, we minimize loss functions.

  • Improved linear classifier model with Nyström

    2018-11-5 · In real-world applications, most data sets consist of interlaced-distributed samples from multiple classes. If samples cannot (can) be classified correctly with a linear hyperplane, we name them nonlinearly (linearly) separable samples. As we know, linear classifiers including HK, MHKS, and SVM are feasible to process linearly separable samples.

    2016-7-1 · The single linear classifier used in D-KSVD is rather weak in terms of discrimination. Motivated by the success of the multiple classifier learning methods , , , we propose to learn multiple classifiers instead of a single one. Meanwhile, we argue that the subdictionaries of a discriminative dictionary should be also discriminative, implying that subsets of discriminative sparse codes should …
