- Precision: The proportion of true positive predictions out of all positive predictions made by the model.
- Recall: The ratio of true positive predictions to actual positives present in the dataset.
- F1 Score: A harmonic mean between precision and recall that provides a balanced measure of a model’s performance.
|Accuracy||Percentage of correct predictions made by the model.|
|Precision||Proportion of true positive predictions among all positive predictions made by the model.|
|Recall||Ratio of true positive predictions to actual positives present in the dataset.|
|F1 Score||Harmonic mean between precision and recall, providing a balanced measure of performance. It considers both false negatives (missed instances) and false positives (incorrectly classified instances).|
Evaluating an NLP model allows us to assess its strengths and weaknesses objectively. By considering metrics such as accuracy, precision, recall, and F1 score, we gain insight into how well our model performs on specific NLP tasks. With this information, we can make informed decisions about fine-tuning the model to improve its performance.
In the subsequent section, “Evaluating and Fine-tuning NLP Models,” we will delve deeper into various evaluation techniques and explore methods for optimizing models based on their performance metrics.
