So I recently made a classifier for the MNIST handwritten digits dataset using PyTorch and later, after celebrating for a while, I thought to myself, “Can I recreate the same model in vanilla python?” Of course, I was going to use NumPy for this. Instead of trying to replicate NumPy’s beautiful matrix …
WebThe scores corresponding to every class will tell you the accuracy of the classifier in classifying the data points in that particular class compared to all other classes. The support is the number of samples of the true response that lie in that class. You can find documentation on both measures in the sklearn documentation. WebNaive Bayes is the most straightforward and fast classification algorithm, which is suitable for a large chunk of data. Naive Bayes classifier is successfully used in various applications such as spam filtering, text classification, sentiment analysis, and recommender systems. It uses Bayes theorem of probability for prediction of unknown class.
