Stack sparse matrices vertically (row wise) Parameters: blocks. sequence of sparse matrices with compatible shapes. formatstr, optional. sparse format of the result (e.g., “csr”) by default an appropriate sparse matrix format is returned. This choice is subject to change. WebDictVectorizer implements what is called one-of-K or “one-hot” coding for categorical (aka nominal, discrete) features. Categorical features are “attribute-value” pairs where the value is restricted to a list of discrete possibilities without ordering (e.g. topic identifiers, types of objects, tags, names…).

One-hot Encoding is a type of vector representation in which all of the elements in a vector are 0, except for one, which has 1 as its value, where 1 represents a boolean specifying a category of the element.
WebThe label encoded (or integer encoded) target variables are then one-hot encoded. This is a probabilistic representation of the class label, much like the softmax output. A vector is created with a position for each class label and the position. All values are marked 0 (impossible) and a 1 (certain) is used to mark the position for the class label.
