Model Development and Testing Define Use Cases Identify the specific problems or tasks the AI model will address, such as drug discovery, clinical trial optimization, or adverse event prediction. Set Up Development Environment Ensure the necessary infrastructure, tools, and libraries are in place to build, train, and test the AI model, such as cloud computing resources, data preprocessing pipelines, and model training frameworks. Gather and Prepare Data Collect and preprocess the relevant data for model training, including clinical trial data, medical literature, and chemical compound information, ensuring data quality and addressing any biases or imbalances. Design Model Architecture Determine the appropriate AI model architecture, such as neural networks, decision trees, or ensemble methods, based on the problem domain and the characteristics of the data. Train and Validate the Model Split the data into training, validation, and test sets, and train the AI model, monitoring for overfitting and adjusting hyperparameters as needed to optimize performance. Prepare for Model Testing Develop a comprehensive testing plan, including unit tests, integration tests, and end-to-end tests, to ensure the model's reliability, robustness, and compliance with regulatory requirements.
