What is the objective of a Process Controller in relation to machine learning models?

The objective of a Process Controller in relation to machine learning models is to monitor model performance. This role involves continuously assessing how well the deployed models are functioning in a production environment. A Process Controller ensures that the models maintain accuracy and reliability over time, adapting to changes in data patterns or operational conditions. This ongoing evaluation can include tracking metrics like accuracy, precision, recall, and other performance indicators, enabling timely interventions if the model's performance begins to degrade.

Training and validation of models would typically fall under the responsibilities of data scientists or machine learning engineers, as these tasks require creating models from data, while creating new algorithms is more about research and development in the machine learning field. Deploying existing models is another distinct responsibility that comes after training and validation, focusing on making models available for use in business applications rather than performance monitoring.
