## Best 6 Machine Learning Algorithm For Data Science

Machine learning, statistical analysis, and data mining all fall within the purview of data scientists. Algorithms and statistical analysis, when combined, can glean fresh insights from data that has previously been gathered.

If one method doesn’t work for every problem, there are a range of machine learning algorithms to choose from in data science. Different types of machine learning algorithms are often used by data scientists.

## 1. Linear and Logistic Regression

A Linear Regression Analysis

The estimation of relationships between dependent variables is done using regression analysis. Regression problems are often addressed using linear regression. In comparison, classification problems are typically managed using logistic regression. Estimation using linear regression has been around for more than two centuries.

Let’s say you have a variable y that is linearly dependent on the variable x. The constants a and B in the equation y = ax and b. It may be formulated using regression analysis. Both x and y are represented by these constants, which show how linearly connected they are.

Using Linear Regression, one or more predictive variables (s) and an outcome factor may be identified. Linear Regression is an excellent tool if you’re just getting started with data science. To complete this assignment, students must compute the properties of their training datasets.

Kaggle’s Swedish Auto Insurance Dataset uses linear regression analysis to explore the relationships between various data sets. The study estimates the overall cost of all insurance claims based on the number of shares.

## 2. Regression with Logistic Constraints

To build machine learning models, statisticians use a technique known as logistic regression. In which each dependent variable has a binary or dichotomous value. One or more independent variables and one or more dependent variables can be explained using this technique. Using Logistic Regression, Coursera has been able to predict the value of homes based on their many qualities.

## 3. Decision Trees and Random Forests.

A decision tree is the organization of facts into a logically structured structure. Data is partitioned into several branches at each node in the tree structure. The properties on the nodes are used to separate the data. On the other hand, the decision trees are vulnerable to significant variations.

Many examples of machine-learning algorithms show high variations. They result in unsatisfactory decision tree results for the specific training data used. Using the same training data, you may create many highly connected trees to reduce variation.

With this method, you may avoid making mistakes in your decision trees by using the term ‘bagging’ to describe the procedure. Bagging has been expanded in Random Forest. Additionally, the machine learning technique restricts the features. That may be used to build the trees from distinct training data samples. This necessitates that each decision tree is unique.

A team from the Institute of Physics employed random forests and decision trees in a recent study to predict loan default. A list of possible loan applicants may be narrowed down using machine learning algorithms. The researchers constructed it using real-world samples.

Researchers employed random forests and decision trees in their work. The researchers used decision trees and random forests. To assess the risk of each potential borrower (from the list of potential candidates). They used both machine learning methods and the Random Forest algorithm concerning the same set of data. Compared to Decision Trees, researchers found that Random Forests yielded more accurate findings.

## 4.  Boosting Machines for Gradients

Top machine learning techniques for training with tabular datasets include gradient boosting devices. Such as XGBoost, LightGBM, and CatBoost. To make XGBoost easier to work with it is transparent. It allows easy tree visualization and does not encode any category features.

Researchers used three high-powered boosting machines (XGBoost, LightGBM, and CatBoost) to categorize land cover in Vietnam. At the Center for Applied Research in Remote Sensing and GIS (CARGIS).

Using CNN-based gradient boosting machine learning techniques and object-based image analysis. The study found that this combination might yield an accurate approach to landcover investigation.

## 5. Fourier Transforms and Convolutional Neural Networks (CNN)

A variety of machine learning methods are used by CNN to categorize pictures. The picture characteristics are removed from the data set by the various layers of CNN. They begin to organize the photos over time.

The first network. Car traffic density estimate method generated from satellite photos of modest size for frequent remote sensing of traffic.

In a recent case study, Omdena documented how CNN’s efforts improved road safety. Cars on the road were categorized and counted using pre-trained CNN. The algorithms also analyzed traffic patterns and satellite pictures to create safer traffic flow rules. Learn more about it below.

## 6. Bayesian Methodologies

Classifiers based on the Bayes Theorem are called naive Bayes classifiers. The Naive Bayes classification technique is assigned to the array element with the highest probability based on Bayes Theorem.

Let’s assume that the two cases are both random events.

Let P (A) be the probability that A is real.

The chance that A will be confirmed if B is true is called P(AB).

As a result, according to the Bayes theorem:

(P (B|A) x P (A)) /P (B)
