The Best 10 ML Algorithms

Linear Regression

Imagine sorting random wood logs by weight to learn Linear Regression. You cannot measure each log. You must estimate its weight by visually analyzing the log’s height and girth and arranging them. This is machine learning linear regression.

Linear regression is used to determine the nature of the relationship between the independent and dependent variables. Using the linear model Y= a * X + b, we can get the slope and intercept of this line, also known as the linear regression.

This formula includes:

The Y-Factor Is The Dependant One

Independent variable (X) slope (a) and a (b) intercept

Minimizing the total squared deviation of data points from the regression line yields the coefficients a and b.

Logistic Regression

Logistic regression estimates discrete values (typically binary like 0/1) from independent variables. Fitting information to a logit model predicts event likelihood. It’s logit regression.

These strategies enhance logistic regression models:

• interrelationships
• remove features
• regularize uses a non-linear model.

• Decision Tree

The Decision Tree algorithm is a common supervised learning algorithm for problem classification in the field of machine learning. Classifying continuous and categorical dependent variables is where it really shines. The population is split into a number of distinct groups using this technique, with each group sharing only the most important characteristics.

SVM Algorithm

Classification algorithms such as the Support Vector Machine (SVM) technique involve plotting original information as pixels in an n-dimensional domain. This makes it simple to categorize the data because the value of each attribute is associated with a specific location. Splitting the data and plotting it on a graph can be done with the use of lines called classifiers.

Naïve Bayes Algorithm

Naive Bayes classifiers assume that a class’s features are unrelated. A Naive Bayes classification would calculate the probability of an event irrespective of these features, even if they are connected. Naive Bayesian models are simple and useful for large datasets. It’s simple and outperforms complex classification methods.

KNN Algorithm

This algorithm works for classification and regression. It’s used more for categorization in Data Science. Simple algorithm stores all cases and classifies new cases by simple majority of its k neighbors. The most similar class receives the case. Distance functions measure this. Real-life examples help explain KNN. If you want to know someone, chat to their friends and coworkers!

K Means

Unsupervised learning handles clustering difficulties. Data sets are divided into K clusters, each with homogeneous and heterogeneous data points.

K-means clustering:

K-means selects k centroids for each cluster.

Data points form K clusters with the nearest centroids.

It now generates centroids from cluster members.

These centroids calculate each data point’s closest distance. Repeat until centroids remain unchanged.

Random Forest Algorithm

Random Forests are decision trees. Each tree is classed and “votes” to categorize a new object depending on its attributes. The forest chooses the highest voted classification.

Planting and growing each tree:

Randomly sample N examples from the training set. This sample will train the tree.

If there are N input parameters, a value n<<N is supplied to randomly select m variables at each node and split the node using the optimal split on this m. This technique maintains m. Each tree is fully developed. No pruning.

Dimensionality Reduction Algorithms

Organizations in many sectors of society, from the private sector to government, and the academic world, are collecting, storing, and analyzing massive volumes of data. You, as a data scientist, are well aware of the vast amounts of information included in this raw data; the trick is to extract the most relevant patterns and variables.

Gradient Boosting Algorithm & Ada Boosting Algorithm

When large amounts of data must be processed in order to create precise predictions, boosting techniques like the Gradient Boosting Algorithm or the AdaBoosting Algorithm come into play. Boosting is a technique for ensemble learning that increases robustness by combining the prediction power of multiple base estimators. In a nutshell, it takes a collection of mediocre or unreliable predictors and uses their combined strengths to create a single reliable one. Machine learning competitions like Kaggle, AV Hackathon, and CrowdAnalytix have consistently found success with these boosting methods. These algorithms are the most popular choices for machine learning today. They can be used in conjunction with programming languages like Python and R to produce reliable results.
