I'm working on a machine learning project, and my dataset contains variables about social, demographic and economic aspects of 218 countries, ranging from 1960 to 2022. The target variable is a binary variable (Yes or No) that represents if the country has had at least one attempt of coup...

Machine learning algorithms have hyperparameters that allow you to tailor the behavior of the algorithm to your specific dataset. Hyperparameters are different from parameters, which are the internal coefficients or weights for a model found by the learning algorithm. Unlike parameters, hyperparameters ...

Learn about classification in machine learning, looking at what it is, how it's used, and some examples of classification algorithms.
Classification is a supervised machine learning process that predicts the class of input data based on the algorithms training data. Here’s what you need to know.
Traditional text classification works mainly focus on three topics: feature engineering, feature selection and using different types of machine learning algorithms. For feature engineering, the most widely used feature is the bag-of-words feature. In addition, some more complex features have been desig...

Fig. 1. Conceptual Approach: Using Machine Learning for Marketing Problems. 2.2. Reasons for machine learning biases The decision-making of algorithms is very different to human decision-making in two important ways: algorithms are extremely literal and they are black boxes. First, while humans und...
In this paper we use machine learning algorithms like SVM, KNN and GIS to perform a behaviorcomparison on the web pages classifications problem, from the experiment we see in the SVM with smallnumber of negative documents to build the centroids has the smallest storage requirement and the least...
