one of the groups or classes into which things may be or have beenclassified.classify. Biology.the assignment of organisms to groups within a system of categories distinguished by structure, origin, etc. The usual series of categories isphylum(or, especially in botany,division),class, order, fa...
Sometimes, we may need to classify the response with more than two classes; in other words, we need to perform multiclass classification. Although the two-class logistic regression model can be extended to multiple-class extentions, but in practice they tend not to be used very often because ...
Coefficient. Intercept = -10.6513, meaning that the log odds of default is -10.6513 if the person does not have any bank balance. In other words, the leaning method will against you default. On the other hand, the coefficient of balance if 0.0055, meaning that each unit increase in balance...
In other words, this is a tree that classifies the original training set well, but the structure of the tree is sensitive to this particular training set so that its performance on new data is likely to degrade. It is often possible to find a simpler tree that performs better than a ...

Clustering: In clustering, a set of observations are grouped into subsets, also known as clusters. Clustering consists of partitioning a group of elements into subsets according to the discrepancies between them. In other words, it is the act of grouping together similar elements. The key distinct...
For the decision tree algorithm, the cross-validation error estimate is significantly larger than the resubstitution error. This shows that the generated tree overfits the training set. In other words, this is a tree that classifies the original training set well, but the structure of the tree...
What we need is a function that calculates a probability value forybased onx(in other words, we need the functionf(x) = y). You can see from the chart that patients with a low blood-glucose level are all non-diabetic, while patients with a higher blood-glucose level are diabetic. It...
Class separation is important. In other words, classes among the training (and test) data should be semantically distinguishable from each another in order to avoid misclassifications. Since the classifier algorithms in Watson Natural Language Processing rely on word embeddings, training classes that co...
