Web30 nov. 2024 · Classification can be binary or multiclass, Binary classification comprises of two values either true or false, i.e., ... The MNIST dataset is a collection of 70,000 small images of digits handwritten by school students and employees of the US Central Bureau. WebFirst we show how an EstimatorQNN can be used for classification within a NeuralNetworkClassifier. In this context, the EstimatorQNN is expected to return one-dimensional output in [ − 1, + 1]. This only works for binary classification and we assign the two classes to { − 1, + 1 }. We will add a callback function called callback_graph. …
