Definition: In the context of artificial intelligence and machine learning, "retrained" refers to a process where an existing model or algorithm is modified or updated in some way to improve its performance. This can include changes in the model's architecture, training data usage, hyperparameters, or even modifications to the algorithm's behavior. Retraining typically involves using new data that was not previously used during training to improve the model's accuracy and generalization ability. It could also involve fine-tuning the model for a specific
