(4 Questions)
- Q1. In depth questions on every ml algorithm from supervised to un supervised algorithms
- Q2. How to over come over fitting
- Ans.
To overcome overfitting, use techniques like cross-validation, regularization, early stopping, and increasing training data.
Use cross-validation to evaluate model performance on different subsets of data.
Apply regularization techniques like L1 or L2 regularization to penalize large coefficients.
Implement early stopping to stop training when validation error starts to increase.
Increase training data to provide more dive
- Q3. What is PCA, how to do feature selection
- Ans.
PCA is a dimensionality reduction technique used to reduce the number of features in a dataset while preserving the most important information.
PCA stands for Principal Component Analysis
It works by finding the directions (principal components) in which the data varies the most
These principal components are orthogonal to each other and capture the maximum variance in the data
Feature selection can be done by selecting th...

- Q1. What is overfitting and underfitting?
- Ans.
Overfitting occurs when a model learns the training data too well, leading to poor generalization. Underfitting happens when a model is too simple to capture the underlying patterns.
Overfitting: Model performs well on training data but poorly on unseen data. Can be caused by a model being too complex or training for too long.
Underfitting: Model is too simple to capture the underlying patterns in the data. Results in po...

- Q2. Polymorphism, inheritance
- Q3. OOPs, 4 pillars of OOPs
- Ans.
OOPs stands for Object-Oriented Programming and its 4 pillars are Inheritance, Encapsulation, Abstraction, and Polymorphism.
Inheritance allows a class to inherit properties and behavior from another class.
Encapsulation restricts access to certain components of an object, protecting its integrity.
Abstraction hides complex implementation details and only shows the necessary features.
Polymorphism allows objects to be trea...

- Q1. Explain the transformer architecture and positional encoders?
- Ans.
Transformer architecture is a neural network architecture used for natural language processing tasks. Positional encoders are used to encode the position of words in a sentence.
Transformer architecture is based on the self-attention mechanism.
It consists of an encoder and a decoder.
Positional encoders are added to the input embeddings to encode the position of words in a sentence.
They are computed using sine and cosine...
