  • Ans. 

    Faster-RCNN and Yolo v3 are both object detection algorithms, but differ in their approach and performance.

    • Faster-RCNN uses a two-stage approach, first generating region proposals and then classifying them.

    • Yolo v3 uses a single-stage approach, directly predicting bounding boxes and class probabilities.

    • Faster-RCNN is generally more accurate but slower, while Yolo v3 is faster but less accurate.

  • Q2. How RNN handles exploding/vanishing Gradient?
  • Ans. 

    RNN uses techniques like gradient clipping, weight initialization, and LSTM/GRU cells to handle exploding/vanishing gradients.

    • Gradient clipping limits the magnitude of gradients during backpropagation.

    • Weight initialization techniques like Xavier initialization help in preventing vanishing gradients.

    • LSTM/GRU cells have gating mechanisms that allow the network to selectively remember or forget information.

    • Batch normaliza...
