  • Linear classifier - WikiMili, The Best Wikipedia Reader

    If the score was the opposite, if the score of x were less than zero, then we'd have predicted it's a negative sentence. So this is how a linear classifier works, if you know the weight of each word, and this is called a linear classifier because the output is basically the weighted sum of the input.

    The only possibility is to draw hyperplanes for linear classifier. In 1992, Bernhard E. Boser, Isabelle M Guyon and Vladimir N Vapnik suggested a way to create non-linear classifiers by applying the kernel trick to maximum-margin hyperplanes. The current standard was proposed by Corinna Cortes and Vapnik in 1993 and published in 1995.
