- Q1. What is Transformers and how they work
- Ans.
Transformers are models used in natural language processing tasks, known for their ability to handle long-range dependencies.
Transformers use self-attention mechanism to weigh the importance of different words in a sentence.
They consist of encoder and decoder layers, with each layer containing multi-head attention and feed-forward neural network.
Examples of transformer models include BERT, GPT-3, and TransformerXL.
- Q2. How to train a model with imbalance data
- Ans.
Use techniques like oversampling, undersampling, SMOTE, or ensemble methods to train a model with imbalanced data.
Use oversampling to increase the number of minority class samples.
Use undersampling to decrease the number of majority class samples.
Use Synthetic Minority Over-sampling Technique (SMOTE) to generate synthetic samples for the minority class.
Utilize ensemble methods like Random Forest or Gradient Boosting to
