WebJul 7, 2024 · We saw that a perceptron is an algorithm to solve binary classifier problems. This means that a Perceptron is abinary classifier, which can decide whether or not an input belongs to one or the other class. E.g. "spam" or "ham". We accomplished this by linearly combining weights with the feature vector, i.e. the input. WebApr 10, 2024 · 首先得将数据处理为可用于训练分类器的形式。 为了对这个数据进行分类,首先需要将数据处理成可用于训练分类器的形式。
