• Autoencoders is a supervised learning algorithm

• k-means is Density-based clustering

Select true statement about clustering

• the goal is to maximize intra-cluster distance

• the goal is to maximize intra-cluster similarity

• in Distribution-based clustering the algorithm clusters members that are closely packed together

which statements are true

• Precision refers to proportion of Actual positive casses that were correctly identified

• if your model always outputs a positive prediction, it would have 100% recall but be completely uninformative

• F1 score = 2 * Precision * Recall / Precision + recall

Select correct statements

• The Linear Regression and Logistic Regression is used for solving Regression problems

• in Linear regression Gradient descent can help minimizing error at each step of the model training process

• residual should be normally distributed

select correct statement

• Deep learning is a Parametric approach

• Deep learning requires massive amounts of training data

• explicit feature engineering required in classical ML
