The Four categories of machine learning algorithms
Let's look at the various sorts of machine learning algorithms and how they are categorized before getting into the top 10 machine learning algorithms you should be familiar with.
Four categories of machine learning algorithms are recognized:
-
Supervised
-
Unsupervised Learning
-
Semi-supervised Learning
-
Reinforcement Learning
However, these four ML algorithm types are further divided into other categories.
If you want to get into the machine learning field, you can join Machine Learning Online Course and learn types of machine learning algorithms, algorithms in data science, the use of algorithms, and machine learning basic concepts.
How does machine learning work?
With the use of machine learning (ML), which is a form of artificial intelligence (AI), software programmes can predict outcomes more accurately without having to be explicitly instructed to do so. In order to forecast new output values, machine learning algorithms use historical data as input.
Machine learning is frequently used in recommendation engines. Business process automation (BPA), predictive maintenance, spam filtering, malware threat detection, and fraud detection are a few additional common uses.
If you want to become an AI engineer, you can join an Artificial Intelligence Course in Chennai and learn the machine learning algorithms, types of machine learning algorithms, algorithms in data science, machine learning basic concepts and algorithm techniques.
What Are The 10 Popular Machine Learning Algorithms?
The top 10 most popular machine learning (ML) algorithms are listed below:
How Learning These Vital Algorithms Can Enhance Your Skills in Machine Learning
If you intend to becoem a data scientist or in the role of a data scientist or machine learning engineer, you can utilize these strategies and techniques for creating functional Machine Learning projects.
The most common machine learning algorithms fall into three categories: supervised learning, unsupervised learning, and reinforcement learning. The following list of 10 popular machine learning algorithms employs all three methods:
List of Popular Machine Learning Algorithms
Linear Regression
If you want to understand the linear regression process, assume how you could arrange the random wooden logs of their weight in increasing order. There we face the challenge- you cannot weigh each log.
You have to estimate its weight simply by seeing the log's height and girth (visual analysis) and arranging them according to a combination of these observable criteria. Similar to this is linear Regression in machine learning.
By fitting the independent and dependent variables to a line, this procedure establishes a relationship between them. The equation Y=a*X+b, often known as the regression line, describes this line.
In this equation:
-
Y – Dependent Variable
-
a – Slope
-
X – Independent variable
-
b – Intercept
The squared difference in distance between the data points and the regression line is added to get the coefficients a and b.

Logistic Regression
Using logistic Regression, a set of independent variables estimates discrete values (often binary values like 0/1). Fitting data to a logit function aids in predicting an event's probability. Logit regression is another name for it.
The method mentioned below will aid you in improving logistic regression models:
Decision Tree
Nowadays, one of the most well-known machine learning algorithms is the decision Tree method, a supervised learning technique used to categorize issues.
Both categorical and continuous dependent variables can be classified well with it. The population is split into two or more identical sets using this method, depending on the most important characteristics or independent variables.
If you want to head your career as a data scientist, you can join a Data Science Courses in Bangalore and learn the Data Science Life Cycle, Artificial Intelligence (AI), Implementation of Artificial Intelligence, Machine Learning and deep learning.
SVM (Support Vector Machine) Algorithm
The SVM algorithm is a technique for classifying data that involves plotting raw data as points in an n-dimensional space (where n is the number of features you have). It is, therefore, simple to categorize the data because each feature's value is connected to a specific coordinate. To separate the data and plot them on a graph, employ lines known as classifiers.
Naive Bayes Algorithm
A Naive Bayes classifier assumes that a specific characteristic inside a class is unconnected to the existence of any other feature.
When determining the likelihood of a specific result, a Naive Bayes classifier would consider each of these characteristics independently, even if these features are connected.
A Naive Bayesian model is simple to construct and effective for large datasets. Despite being basic, it is known to perform better than even the most complex categorization techniques.
KNN (K- Nearest Neighbors) Algorithm
K- Nearest Neighbors algorithm is applied for classifying and regression problems. This type of algorithm is used in data science because this K- Nearest Neighbors method helps the data scientist to solve the classification problem. This significant algorithm stores all available cases and classifies new cases by taking a majority vote of its k Neighbors.
If you want to become a data scientist, you can join the Data Science Course in Pune, which will help you have a comprehensive understanding of algorithms in data science, how to learn algorithms, algorithm techniques, and many other core concepts of data science.
The class with which the case shares the most characteristics is then given a case. This calculation is made using a distance function.
KNN can be easily comprehended by using an analogy to everyday life. For instance, speaking with a person's friends and colleagues makes sense if you want to learn more about them. Before choosing the K Nearest Neighbors algorithm, keep the following in mind:
-
The computation complexity of KNN is high.
-
Higher range variables should be standardized to prevent algorithm bias.
-
Preprocessing of the data is still necessary.
K-Means
It is categorized under the unsupervised learning algorithm. This unsupervised learning algorithm will help you solve clustering problems.
This K-means algorithm can classify data sets into a specific cluster set. The data set within the cluster can be heterogeneous and homogeneous.

How K-means forms clusters:
-
The K-means algorithm selects k centroids, or points, for each cluster.
-
With the nearest centroids or K clusters, each data point forms a cluster.
-
Now, new centroids are produced using the cluster members already present.
-
These new centroids determine each data point's closest distance.
-
Unchanged centroids are achieved by repeating this technique.
Random Forest Algorithm
The term "Random Forest" refers to a collection of decision trees. Each tree "votes" for a particular class by categorizing a new object according to its properties. The classification with the highest votes is selected by the forest (over all the trees in the forest).
The following is how each tree is planted and grown:
-
If the training set has N cases, then a random sample of N cases is chosen. This sample will serve as the tree's training set.
-
If the number of input variables is M, then a number m<<M is specified, and the best split on this m is used to split each node. At each node, m variables are randomly chosen from the M.
-
During this procedure, m's value is kept constant.
-
The entire possible development is given to each tree. No pruning.
Dimensionality Reduction Algorithms
In the modern world, businesses, governments, and research institutions store and manage huge amounts of data. As a data scientist, you know that this raw data has a lot of data. The challenge is identifying significant patterns and variables.
You can retrieve relevant data using dimensionality reduction methods like Decision Trees, Factor Analysis, Missing Value Ratio, and Random Forest.

Gradient Boosting Algorithm and AdaBoosting Algorithm
To create predictions with a high degree of accuracy, boosting techniques like the Gradient Boosting Algorithm and the AdaBoosting Algorithm are utilized. A group learning approach known as "boosting" enhances robustness by combining the predictive capability of numerous base estimators.
In other words, it fuses several weak or average predictors to create a powerful predictor. These boosting algorithms do well in data science competitions like CrowdAnalytix, AV Hackathon, and Kaggle. These machine-learning algorithms are currently the most popular ones. Use these along with the Python and R codes to get precise results.
