Regression is a statistical method used to analyze the relationship between variables. Different types include linear, logistic, polynomial, etc.

• Regression is a statistical technique used to understand the relationship between a dependent variable and one or more independent variables.

• Different types of regression include linear regression, logistic regression, polynomial regression, ridge regression, and lasso regression.

• Linear regression is used when the relationship betwee...read more

Supervised learning involves training a model on labeled data, while unsupervised learning involves finding patterns in unlabeled data.

• Supervised learning requires a target variable to be predicted, while unsupervised learning does not.

• Examples of supervised learning include classification and regression tasks, while examples of unsupervised learning include clustering and dimensionality reduction.

• In supervised learning, the model learns from the labeled data provided during ...read more

Mutability refers to the ability of an object to be changed after it is created, while immutability refers to the inability of an object to be changed once it is created.

• Mutability allows for changes to be made to an object's state, while immutability ensures that an object's state remains constant.

• In programming, mutable objects can be modified directly, while immutable objects require creating a new object with the desired changes.

• Examples of mutable objects include lists a...read more

Logistic Regression is a statistical method used to model the relationship between a binary outcome variable and one or more predictor variables.

• Logistic Regression is used when the dependent variable is binary (e.g. 0/1, Yes/No, True/False).

• It estimates the probability of a certain event occurring based on one or more independent variables.

• The output of logistic regression is a probability score that can be converted into class labels using a threshold value.

• It is commonly u...read more

List is mutable, Tuple is immutable in Python.

• List can be modified after creation, Tuple cannot be modified

• List is defined using square brackets [], Tuple is defined using parentheses ()

• Example: list_example = [1, 2, 3], tuple_example = (1, 2, 3)

OOPM stands for Object-Oriented Project Management, a methodology that focuses on managing projects using object-oriented principles.

• OOPM emphasizes breaking down projects into smaller, manageable components called objects

• It promotes reusability, modularity, and flexibility in project development

• Examples of OOPM tools include UML (Unified Modeling Language) and Agile methodologies
