There are many different types of classification tasks that you may encounter in machine learning and specialized approaches to modeling that may be used for each. In this tutorial, you will discover different types of classification predictive modeling in machine learning. After completing this tutoria...
There are four main classification tasks in Machine learning: binary, multi-class, multi-label, and imbalanced classifications. Binary Classification In a binary classification task, the goal is to classify the input data into two mutually exclusive categories. The training data in such a situation...
The author in this chapter will showcase various ML tasks with case studies using Python programing language so that the novice readers in this field can start their learning curve smoothly.doi:10.1016/B978-0-12-819443-0.00016-7Tilottama Goswami...

Overfitting is a common problem in machine learning and it occurs in most models. K-fold cross-validation can be conducted to verify that the model is not overfitted. In this method, the data set is randomly partitioned into k-mutually exclusive subsets, each approximately equal in size. One...
In machine learning tasks, classification is a supervised learning method to predict the label given the input data. For example, we want to predict if someone is interested in the sales offering using their historical features. By training the machine learning model using available training data,...
Also Classification is one of supervised learning tasks, meaning that training data we feed to algorithms include both features and labels and that we try to predict the classes based on the features. when trying to predicting classes of response, we usually prefer not to use linear regression....
The induction of classifiers from data sets of pre-classified instances, usually called training data, is one of the fundamental tasks in Machine Learning (Stanke and Waack, 2003). The process of modelling from training data, i.e., building up the mapping from observed features/attributes to ...
When it comes to advanced tasks like defining emotions in text or detecting spam – that’s where rule-based systems meet their limitations. Machine learning classification with natural language processing (NLP) Working with more complex text classification tasks requires natural language processing or ...
For more on approximating functions in applied machine learning, see the post: How Machine Learning Algorithms Work Generally, we can divide all function approximation tasks into classification tasks and regression tasks. Classification Predictive Modeling ...
