- **Try Different Models**: Experiment with other models like SVM, RandomForest, or GradientBoosting. - **Feature Engineering**: Consider additional feature engineering techniques to improve model performance. - **Class Imbalance**: If your…

SVMs can be effective, especially with the right kernel and parameter tuning. ### 4. **Decision Tree Classifier** Decision Trees are simple yet effective for certain types of data and can be used as a baseline. ### 5. **Naive Bayes Classi…

By trying multiple models and performing hyperparameter tuning, you can identify the best model for your dataset and improve the recall score. This approach allows you to leverage the strengths of different algorithms and find the one that …

Decision Trees are relatively fast to train and can handle sparse data well. They are particularly useful as a baseline model. ### 4. **Linear Support Vector Machine (SVM)** A linear SVM can be quite fast to train, especially with sparse d…
