Main Methods:

• An integrated deep learning architecture combining Convolutional Neural Networks (CNNs), Recurrent Neural Networks (RNNs), and Mixture Density Networks (MDNs) was developed.
• The proposed model leverages the strengths of CNNs for feature extraction, RNNs for sequential data, and MDNs for probabilistic output.

Main Results:

• The integrated convolutional mixture density recurrent neural network demonstrated superior performance compared to existing models.
• Extensive comparative analysis confirmed the model's significant outperformance in predicting drug-drug interaction scores.

Conclusions:

• The proposed integrated deep learning model offers a more effective solution for predicting drug-drug interaction scores.
