1. What is the Impact of Outliers on Logistic Regression?

The estimates of the Logistic Regression are sensitive to unusual observations such as outliers, high leverage, and influential observations. Therefore, to solve the problem of outliers, a sigmoid function is used in Logistic Regression.


2. What is the difference between vanilla RNNs and LSTMs?


The main difference between vanilla RNNs and LSTMs is that LSTMs are able to better remember long-term dependencies, while vanilla RNNs tend to forget them. This is due to the fact that LSTMs have a special type of memory cell that can retain information for longer periods of time, while vanilla RNNs only have a single layer of memory cells.

3. What is Masked Language Model in NLP?


Masked language models help learners to understand deep representations in downstream tasks by taking an output from the corrupt input. This model is often used to predict the words to be used in a sentence.


4. Why is the KNN Algorithm known as Lazy Learner?

When the KNN algorithm gets the training data, it does not learn and make a model, it just stores the data. Instead of finding any discriminative function with the help of the training data, it follows instance-based learning and also uses the training data when it actually needs to do some prediction on the unseen datasets. As a result, KNN does not immediately learn a model rather delays the learning thereby being referred to as Lazy Learner.

βœ… Top Deep Learning Interview Questions & Answers πŸ€–πŸ§ 

πŸ“ 1. What is Deep Learning?
Answer: A subset of Machine Learning that uses multi-layered neural networks to learn patterns from large datasets. It excels in image recognition, speech processing, and NLP.

πŸ“ 2. What is a Neural Network?
Answer: A system of interconnected nodes (neurons) organized in layers β€” input, hidden, and output β€” that process data using weights and activation functions.

πŸ“ 3. What are Activation Functions?
Answer: They introduce non-linearity into the network. Common types:
⦁ ReLU: max(0, x) β€” fast and widely used
⦁ Sigmoid: outputs between 0 and 1
⦁ Tanh: outputs between -1 and 1

πŸ“ 4. What is Backpropagation?
Answer: The process of updating weights in a neural network by calculating the gradient of the loss function and propagating it backward using chain rule.

πŸ“ 5. What is Dropout?
Answer: A regularization technique that randomly disables neurons during training to prevent overfitting.

πŸ“ 6. What is Transfer Learning?
Answer: Using a pre-trained model on a new, related task. Example: fine-tuning ResNet for medical image classification.

πŸ“ 7. What are CNNs used for?
Answer: Convolutional Neural Networks are ideal for image and video data. They use filters to detect spatial hierarchies like edges, shapes, and textures.

πŸ“ 8. What are RNNs and LSTMs?
Answer:
⦁ RNNs handle sequential data but suffer from vanishing gradients.
⦁ LSTMs solve this using memory cells and gates to retain long-term dependencies.

πŸ“ 9. What are Autoencoders?
Answer: Unsupervised neural networks that compress data into a lower-dimensional form and then reconstruct it. Used in anomaly detection and denoising.

πŸ“ 10. What are GANs?
Answer: Generative Adversarial Networks consist of a Generator (creates fake data) and a Discriminator (detects fakes). Used in image synthesis, deepfakes, and art generation.

πŸ“ 11. What is Regularization in Deep Learning?
Answer: Techniques like L1/L2 penalties, Dropout, and Early Stopping help reduce overfitting by constraining model complexity.

πŸ“ 12. What is the Vanishing Gradient Problem?
Answer: In deep networks, gradients can become too small during backpropagation, making it hard to update weights. Solutions include using ReLU and batch normalization.

πŸ“ 13. What is Batch Normalization?
Answer: It normalizes inputs to each layer, stabilizing learning and speeding up training.

πŸ“ 14. What is the role of Epochs, Batches, and Iterations?
Answer:
⦁ Epoch: One full pass through the dataset
⦁ Batch: Subset of data used in one forward/backward pass
⦁ Iteration: One update of weights per batch

πŸ“ 15. What is the difference between Training and Inference?
Answer:
⦁ Training: Model learns from data
⦁ Inference: Model makes predictions using learned weights

πŸ’‘ Pro Tip: Always explain concepts with examples or analogies in interviews. For instance, compare CNN filters to human vision detecting edges and shapes.

Difference between linear regression and logistic regression πŸ‘‡πŸ‘‡

Linear regression and logistic regression are both types of statistical models used for prediction and modeling, but they have different purposes and applications.

Linear regression is used to model the relationship between a dependent variable and one or more independent variables. It is used when the dependent variable is continuous and can take any value within a range. The goal of linear regression is to find the best-fitting line that describes the relationship between the independent and dependent variables.

Logistic regression, on the other hand, is used when the dependent variable is binary or categorical. It is used to model the probability of a certain event occurring based on one or more independent variables. The output of logistic regression is a probability value between 0 and 1, which can be interpreted as the likelihood of the event happening.
