Introduction

In this article we will discuss the Top 10 Machine Learning Tools used by Data Scientists.

Machine Learning is the study of computer algorithms that can automatically learn and improve from the experience without being explicitly programmed

Machine learning algorithms are mainly classified into two categories:

• Supervised Learning
• Unsupervised Learning. 

Supervised Learning: 

• It uses the labeled data to train the model to classify the data or predict the outcomes accurately. 
• Algorithms: Linear Regression, Logistic Regression, Decision Tree, Random Forest, AdaBoost, XgBoost. 
• Example: Classify the spam in your inbox folder, and predict the house prices

Unsupervised Learning: 

• It uses unsupervised algorithms to analyze and cluster the unlabeled dataset.
• These algorithms identify the hidden patterns and make the cluster to make the required conclusion. 
• Algorithms: Principal Component Analysis, Singular Value Decomposition approaches.
• Example: Product and customer segmentation, Similarity Detection, and Recommendation System.
