Data Science is a multi-desciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from structured and unstructured data.
Explain commonly used python packages in Data Science?
Q. Tell me types of machine learning are available?
A. Supervised learning
Unsupervised learning
Reinforcement Learning
Q. What is the Supervised learning in machine learning?
A. Supervised learning – When you know your target variable for the problem statement, it becomes Supervised learning. This can be applied to perform regression and classification.
Q. What is the Unsupervised learning in machine learning?
A. Unsupervised learning – When you do not know your target variable for the problem statement, it becomes Unsupervised learning. This is widely used to perform Clustering.
Example: K-Means and Hierarchical clustering.
Q. Explain Data Science programs commonly used algorithms?
A. Linear regression
Logistic regression
Random Forest
KNN.
