Round 2 - Technical 

(3 Questions)

  • Q1. Most of the question related to NLP.
  • Q2. What is the order of efficiency among MobileNet, DenseNet, and EfficientNet?
  • Ans. 

    EfficientNet is the most efficient, followed by MobileNet and then DenseNet.

    • EfficientNet is the most efficient among the three models due to its use of compound scaling and efficient building blocks.

    • MobileNet is less efficient than EfficientNet but more efficient than DenseNet, as it uses depthwise separable convolutions to reduce computational cost.

    • DenseNet is the least efficient among the three models, as it has a hi...

(2 Questions)

  • Q1. Give a brief about yourself.
  • Q2. Salary Expectation and earliest joining date
Round 2 - Technical 

(6 Questions)

  • Q1. Brief about a project worked in the company.
  • Q2. What is Data Leakage?
  • Ans. 

    Data leakage occurs when information from outside the training dataset is used to create a model, leading to unrealistic performance.

    • Occurs when information that would not be available in a real-world scenario is used in the model training process

    • Can result in overly optimistic performance metrics for the model

    • Examples include using future data, target leakage, and data preprocessing errors

  • Answered by AI
  • Q3. What is Encoder Decoder? What is a Transformer model and explain its architecture?
  • Ans. 

    Encoder Decoder is a neural network architecture used for sequence-to-sequence tasks. Transformer model is a type of neural network architecture that relies entirely on self-attention mechanisms.

    • Encoder Decoder is commonly used in machine translation tasks where the input sequence is encoded into a fixed-length vector representation by the encoder and then decoded into the target sequence by the decoder.

  • Answered by AI
  • Q4. Name some Deep learning models?
  • Ans. 

    Deep learning models include CNN, RNN, LSTM, GAN, and Transformer.

    • Convolutional Neural Networks (CNN) - used for image recognition tasks

    • Recurrent Neural Networks (RNN) - used for sequential data like time series

    • Long Short-Term Memory (LSTM) - a type of RNN with memory cells

    • Generative Adversarial Networks (GAN) - used for generating new data samples

    • Transformer - used for natural language processing tasks

  • Answered by AI
  • Q5. What is Regularization in machine learning?
  • Ans. 

    Regularization is a technique used in machine learning to prevent overfitting by adding a penalty term to the model's loss function.

    • Regularization helps to reduce the complexity of the model by penalizing large coefficients.

    • It adds a penalty term to the loss function, which discourages the model from fitting the training data too closely.

    • Common types of regularization include L1 (Lasso) and L2 (Ridge) regularization.

    • Re...

  • Answered by AI
  • Q6. What is Model Quantization?
  • Ans. 

    Model quantization is the process of reducing the precision of the weights and activations of a neural network model to improve efficiency.

    • Reduces memory usage and speeds up inference by using fewer bits to represent numbers

    • Can be applied to both weights and activations in a neural network model

    • Examples include converting 32-bit floating point numbers to 8-bit integers
