Q3. What is the Diff between Parameters and Hyper Parameters?
Ans. 
Parameters are learned from data; hyperparameters are set before training to control the learning process.
• Parameters are internal to the model, like weights in a neural network.

• Hyperparameters are external configurations, such as learning rate or number of trees in a random forest.

• Example of parameters: weights in linear regression.

• Example of hyperparameters: batch size, number of epochs in training.

Q4. Can we use Logistic Regression for Multi Class Classification?
Ans. 
Yes, Logistic Regression can be adapted for multi-class classification using techniques like One-vs-Rest or Softmax regression.
• Logistic Regression is inherently binary, but can be extended to multi-class using One-vs-Rest (OvR) strategy.

• In OvR, a separate binary classifier is trained for each class, treating it as the positive class and all others as negative.

• Another approach is Softmax regression, which generalizes lo...read more

Q5. What will happen if we will increase the value of K in KNN?
Ans. 
Increasing K in KNN can lead to smoother decision boundaries but may also introduce bias and reduce model sensitivity.
• Higher K values can smooth out noise in the data, leading to more generalized predictions.

• For example, with K=1, the model may overfit to noise, while K=10 may provide a more stable prediction.

• Increasing K can lead to underfitting, where the model fails to capture the underlying patterns in the data.

• Cho...read more

Q6. If you have 50 GB of training data and you want to train your Neural Network on you Local 2 GB RAM, what will you do?
Ans. 
Use techniques like data sampling, mini-batch training, or cloud resources to handle large datasets on limited RAM.
• Data Sampling: Use a subset of the data, e.g., 5 GB, to train the model initially.

• Mini-Batch Training: Train the model on smaller batches of data, e.g., 256 MB at a time.

• Data Augmentation: Generate synthetic data to reduce reliance on the full dataset.

• Use Cloud Services: Leverage platforms like AWS or Goog...read more

Q2. Difference between ETL and ELT, give pros and cons of it.
Ans. 
ETL involves extracting data, transforming it, and then loading it into a target system. ELT involves extracting data, loading it into a target system, and then transforming it.
• ETL: Extract, Transform, Load

• ELT: Extract, Load, Transform

• ETL is suitable for scenarios where data needs to be cleansed and transformed before loading into the target system.

• ELT is suitable for scenarios where raw data needs to be quickly loaded...read more
