IBM Watson Natural Language Classifier Stack Overflow

IBM Watson Natural Language Classifier. Something to keep in mind that when you create the first NLC instance (the little box in Bluemix), this is called a service instance. Within this service instance, you can have up to 7 unique classifiers. If you need to create an 8th classifier, you will need to create a new service instance.

Unsupervised Feature Learning and Deep Learning Tutorial

Softmax regression (or multinomial logistic regression) is a generalization of logistic regression to the case where we want to handle multiple classes. In logistic regression we assumed that the labels were binary y^{(i)} \in \{0,1\}. We used such a classifier to distinguish between two kinds of hand written digits.

How the Naive Bayes Classifier works in Machine Learning

Naive Bayes Classifier. Naive Bayes is a kind of classifier which uses the Bayes Theorem. It predicts membership probabilities for each class such as the probability that given record or data point belongs to a particular class. The class with the highest probability is considered as the most likely class. This is also known as Maximum A Posteriori (MAP).

Explain to Me Generative Classifiers VS Discriminative

Generative Classifiers. A generative classifier tries to learn the model that generates the data behind the scenes by **estimating the assumptions and distributions of the model.It then uses this to predict unseen data, because it assumes the model that was learned captures the real model.
