confusion matrix

### Example Code for Classification Task Here's an example of how you might evaluate a classification task using accuracy and F1 score in Python: ```python from sklearn.metrics import accuracy_score, f1_score, confusion_matrix # Predicti…

Ensure that the training data is clean, representative, and annotated correctly. Poor data quality can significantly impact model performance. - **Tools**: Use spaCy's `spacy lookups` to inspect and validate the training data. - **Techniqu…

3. **Tokenization**: - Tokenized the text data using the tokenizer from the pre-trained model. 4. **PyTorch Dataset**: - Created a custom PyTorch dataset to handle the tokenized data and labels. 5. **Training Arguments**: - Defin…

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…

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…

- **Feature Distribution**: Compare the distribution of features between the training and validation/test datasets. Significant differences in the distribution of key features can indicate skew. - **Label Distribution**: Check if the …
