Q1. Explain AIC and BIC
Ans. 
AIC and BIC are statistical measures used for model selection in the context of regression analysis.
• AIC (Akaike Information Criterion) is used to compare the goodness of fit of different models. It penalizes the model for the number of parameters used.

• BIC (Bayesian Information Criterion) is similar to AIC but penalizes more heavily for the number of parameters, making it more suitable for model selection when the focus...read more

Q2. Difference between xgboost and lightgbm
Ans. 
XGBoost is a popular gradient boosting library while LightGBM is a faster and more memory-efficient alternative.
• XGBoost is known for its accuracy and performance on structured/tabular data.

• LightGBM is faster and more memory-efficient, making it suitable for large datasets.

• LightGBM uses a histogram-based algorithm for splitting whereas XGBoost uses a level-wise tree growth strategy.

Q1. What is Supervised Learning?
Ans. 
Supervised learning is a type of machine learning where the model is trained on labeled data to make predictions or decisions.
• In supervised learning, the algorithm learns from labeled training data, where each example is a pair consisting of an input object and a desired output value.

• The goal is to learn a mapping from inputs to outputs in order to make predictions on unseen data.

• Examples include classification tasks l...read more

Q2. What is immutable vs mutable data structures?
Ans. 
Immutable data structures cannot be modified after creation, while mutable data structures can be changed.
• Immutable data structures: values cannot be changed once created (e.g. strings, tuples)

• Mutable data structures: values can be modified after creation (e.g. lists, dictionaries)
