Training
The model training process is essential in building a generative AI model. In this step, a significant amount of relevant data is used to train the model, which is done using various frameworks and tools such as:
- TensorFlow
- PyTorch
- Keras
Iteratively adjusting the model’s parameters is called backpropagation, a technique used in deep learning to optimize the model’s performance.
During training, the model’s parameters are updated based on the differences between the model’s predicted and actual outputs. This process continues iteratively until the model’s loss function, which measures the difference between the predicted outputs and the actual outputs, reaches a minimum.
Evaluating Model Performance: The Role of Validation Data in Machine Learning"
The model’s performance is evaluated using validation data, a separate dataset not used for training. This helps ensure the model does not overfit the training data and can generalize well to new, unseen data. The validation data is used to evaluate the model’s performance and determine if adjustments to the model’s architecture or hyperparameters are necessary.
The model training process can take time and requires a robust computing infrastructure to handle large datasets and complex models. The selection of appropriate frameworks, tools, and models depends on various factors, such as the data type, the complexity of the data, and the desired output.
