So, we can use K-NN algorithm for this classification. The K-NN model will find similarities between the new data set (input) to the available cat and dog images (training data set).

21/07/2022 We're mainly interested in the classifier's accuracy on the validation set, but it looks like a learning rate of 0.5 gives us the best performance on the validation set and good performance on the training set. Now we can evaluate the classifier by checking its accuracy and creating a confusion matrix. Let's create a new classifier and specify

26/01/2022 For time series classification in a supervised setting where all of the data has class labels, the data set is typically split into three sets of data: the training set, the holdout or validation set, and the test set. The training set is used initially to set the parameters of the algorithms that are chosen to attack the problem.
