Q1. What is dropout?
Ans. 
Dropout is a regularization technique used in neural networks to prevent overfitting by randomly setting some neuron outputs to zero during training.
• Dropout is a regularization technique used in neural networks to prevent overfitting.

• During training, a fraction of neurons are randomly selected and their outputs are set to zero.

• This helps in preventing co-adaptation of neurons and improves generalization.

• Dropout is comm...read more

Q2. What is batch Normalization
Ans. 
Batch Normalization is a technique used to improve the training of deep neural networks by normalizing the input of each layer.
• Batch Normalization helps in reducing internal covariate shift by normalizing the input of each layer.

• It speeds up the training process by allowing higher learning rates and reducing the dependence on initialization.

• It can be applied to convolutional neural networks, recurrent neural networks, ...read more

Q3. What is Random Forest
Ans. 
Random Forest is an ensemble learning method that builds multiple decision trees and merges them to improve accuracy and prevent overfitting.
• Random Forest is a collection of decision trees that are trained on random subsets of the data.

• Each tree in the Random Forest independently makes a prediction, and the final prediction is determined by a majority vote.

• Random Forest is effective for classification and regression ta...read more

Q4. What is confusion matrix
Ans. 
Confusion matrix is a table used to evaluate the performance of a classification model.
• It is a matrix with rows representing the actual class and columns representing the predicted class.

• It helps in understanding the performance of the model by showing true positives, true negatives, false positives, and false negatives.

• It is commonly used in machine learning to evaluate the accuracy of a classification model.

• Example: ...read more

Q5. What is a recurrent neural network
Ans. 
A recurrent neural network (RNN) is a type of neural network designed to handle sequential data by maintaining a memory of previous inputs.
• RNNs have loops that allow information to persist, making them suitable for tasks like speech recognition, language translation, and time series prediction.

• They can process inputs of variable length and are capable of learning patterns in sequences.

• RNNs suffer from the vanishing gra...read more
