The first model has an accuracy of 0.5, which is equivalent to random guessing, indicating that the model is not performing well.However, the high recall score also indicates that the model is producing a high number of false positives, which can be addressed by adjusting the model's threshold or using other evaluation metrics such as the area under the ROC curve (AUC-ROC).Both word2vec and AraVec vectors have their own advantages and disadvantages, and the performance of the ANN model depends on the quality of the pre-trained vectors and the complexity of the text data.It's worth noting that the precision score for the second model is affected by the UndefinedMetricWarning message, which indicates that precision is ill-defined and being set to 0.0 in labels with no predicted samples.both models have low accuracy, it could be due to the fact that the text data is very complex or noisy, and the pre-trained vectors are not able to capture the semantic meaning of the words.The precision is also higher at 0.55, indicating that the model is producing fewer false positives.In summary, the second model using AraVec representation has a better performance compared to the first model, as indicated by the higher accuracy, precision, recall, and F1 score.If the ANN model with AraVec representation has a higher training time than the ANN model with word2vec representation, it could be due to the fact that AraVec vectors are not as optimized as word2vec vectors.However, the low precision indicates that the model is also producing a high number of false positives.Therefore, loading and processing AraVec vectors might take more time.

The first model has an accuracy of 0.5, which is equivalent to random guessing, indicating that the model is not performing well. The precision is also very low at 0.25, meaning that only 25% of the positive predictions made by the model are actually true positives. The recall is 0.5, which means that the model is able to correctly identify half of the positive instances in the dataset. However, the low precision indicates that the model is also producing a high number of false positives. The F1 score, which is the harmonic mean of precision and recall, is also low at 0.33.

On the other hand, the second model using AraVec representation has a higher accuracy of 0.55, which is still not very high, but it is an improvement over the first model. The precision is also higher at 0.55, indicating that the model is producing fewer false positives. The recall is 1.0, which means that the model is able to correctly identify all of the positive instances in the dataset. However, this also means that the model is producing a high number of false positives, which is reflected in the lower precision score. The F1 score is also higher at 0.71, indicating that the model is achieving a better balance between precision and recall.

It's worth noting that the precision score for the second model is affected by the UndefinedMetricWarning message, which indicates that precision is ill-defined and being set to 0.0 in labels with no predicted samples. This can happen when there are no true positive predictions for a particular class, resulting in a division by zero error when calculating precision. To address this issue, we can use the zero_division parameter in the precision_score function to control this behavior.

In summary, the second model using AraVec representation has a better performance compared to the first model, as indicated by the higher accuracy, precision, recall, and F1 score. However, the high recall score also indicates that the model is producing a high number of false positives, which can be addressed by adjusting the model's threshold or using other evaluation metrics such as the area under the ROC curve (AUC-ROC). both models have low accuracy, it could be due to the fact that the text data is very complex or noisy, and the pre-trained vectors are not able to capture the semantic meaning of the words. In this case, fine-tuning the pre-trained vectors or using a more complex model might be necessary.
If the ANN model with AraVec representation has a higher training time than the ANN model with word2vec representation, it could be due to the fact that AraVec vectors are not as optimized as word2vec vectors. Therefore, loading and processing AraVec vectors might take more time.
If the ANN model with word2vec representation has a higher training time than the ANN model with AraVec representation, it could be due to the fact that word2vec vectors have a higher dimensionality than AraVec vectors. Therefore, processing word2vec vectors might take more time.
In general, the choice of pre-trained vectors depends on the specific task and the availability of pre-trained vectors for the language of interest. Both word2vec and AraVec vectors have their own advantages and disadvantages, and the performance of the ANN model depends on the quality of the pre-trained vectors and the complexity of the text data.
