Machine Learning-Based Classification: One of the recent enhancements in data classification techniques, machine learning (ML) involves learning from previous classification decisions as well as patterns. With time, the system is able to identify more subtle forms of data as well as the detail, incl...

Unlike the statistical model, machine learning (ML) algorithms learn from data. These algorithms extract patterns from data and yield a function that represents the behavior of the dataset. The learning is evolved by increasing learning examples. The following section discusses the different classificat...
In General,a Discriminative Model models the decision boundary between the classes. A Generative Model explicitly models the actual distribution of each class.In final both of them is predicting the conditional probability . But Both models learn different probabilities. Training classifiers involve estima...

3 Types of Data Classification and Examples Why categorize data? The answer is often linked to your reasons for engaging in the process in the first place. But nowadays, as multiple uses for data grow, there is no “one-size-fits-all” approach. Across the industry, three traditional approa...

We demonstrate insights into the progress of fear-sentiment over time as COVID-19 approached peak levels in the United States, using descriptive textual analytics supported by necessary textual data visualizations. Furthermore, we provide a methodological overview of two essential machine learning (ML)...
(15 October, OA = 38%, Kappa = 0.31), when senescence had already occurred. Despite these contrasting examples occurring at opposite stages of the growing season, no consistent trend in the overall accuracy over time was observed. The classification using imagery from 14 May, for example, was...
