What are the classification algorithms in machine learning?

Here we have the types of classification algorithms in Machine Learning:

• Linear Classifiers: Logistic Regression, Naive Bayes Classifier.
• Nearest Neighbor.
• Support Vector Machines.
• Decision Trees.
• Boosted Trees.
• Random Forest.
• Neural Networks.

.

Consequently, what is classification algorithm?

A classification algorithm, in general, is a function that weighs the input features so that the output separates one class into positive values and the other into negative values.

Subsequently, question is, what are classes in machine learning? A class denotes a set of items (or data-points if we have to represent them in a vector-space) that have certain common characteristics (or exhibit very similar feature patterns in the ML parlance so as to imply a very specific and common interpretation.

Accordingly, how do you know which classification algorithm to use?

1. 1-Categorize the problem.
2. 2-Understand Your Data.
3. Analyze the Data.
4. Process the data.
5. Transform the data.
6. 3-Find the available algorithms.
7. 4-Implement machine learning algorithms.
8. 5-Optimize hyperparameters.

What are different types of algorithms?

Well there are many types of algorithm but the most fundamental types of algorithm are:

• Recursive algorithms.
• Dynamic programming algorithm.
• Backtracking algorithm.
• Divide and conquer algorithm.
• Greedy algorithm.
• Brute Force algorithm.
• Randomized algorithm.

How do you classify a class?

In biological classification, class (Latin: classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. Other well-known ranks in descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class fitting between phylum and order.

K-NN is a lazy learner because it doesn't learn a discriminative function from the training data but “memorizes” the training dataset instead. For example, the logistic regression algorithm learns its model weights (parameters) during training time.
