I applied via campus placement at Dehradun Institute of Technology, Dehradun and was interviewed before Oct 2023. There were 3 interview rounds.
The first was a mcq based coding round for campus placement
This was a pairing coding round
Unsupervised algorithms are used to find patterns in data without labeled outcomes.
K-means clustering: partitions data into K clusters based on similarity
Hierarchical clustering: creates a tree of clusters based on similarity
Principal Component Analysis (PCA): reduces dimensionality by finding orthogonal components
Association rule mining: discovers interesting relationships between variables in large datasets
I applied via Naukri.com and was interviewed in May 2024. There were 2 interview rounds.
Multicollinearity can be treated by using techniques like feature selection, PCA, or regularization. Imbalanced datasets can be addressed by resampling techniques like oversampling or undersampling.
For multicollinearity, consider using techniques like feature selection to remove redundant variables, PCA to reduce dimensionality, or regularization like Lasso or Ridge regression.
For imbalanced datasets, try resampling te...
Logistic regression is a statistical model used to predict the probability of a binary outcome based on one or more predictor variables.
Logistic regression is used when the dependent variable is binary (0/1, True/False, Yes/No, etc.)
It estimates the probability that a given observation belongs to a particular category.
The output of logistic regression is a probability score between 0 and 1.
It uses the logistic function...

To check if two random variables are independent and its importance in Naive Bayes classification.
Check if the joint probability of the two variables is equal to the product of their marginal probabilities.
If the joint probability is not equal to the product of the marginal probabilities, then the variables are dependent.
Independence assumption is important in Naive Bayes classification as it simplifies the calculation...
