During a security architecture review, the team must select the most precise concept. The controlling description is: Model training performed on a client using only that client's local data. It does not primarily describe collaborative training in which clients keep raw data locally and send model updates to a central coordinator. Which answer BEST fits all of the evidence?

A reviewer is comparing two plausible interpretations. The required concept is defined by this characteristic: Learned weights or gradients returned by a client instead of its raw records. The nearest alternative instead concerns bad weights or gradients submitted to corrupt the global model. Which concept should the reviewer select?

Analysts must distinguish between closely related AI security concepts. The decisive characteristic is: A value indicating how model parameters should change to reduce error. A competing interpretation would instead involve model training performed on a client using only that client's local data. Which concept is the BEST classification?

During a security architecture review, the team must select the most precise concept. The controlling description is: Aggregation that commonly averages client updates before applying them to the global model. It does not primarily describe the shared model initialized, distributed, and updated by a central federated-learning server. Which answer BEST fits all of the evidence?

A reviewer is comparing two plausible interpretations. The required concept is defined by this characteristic: Repeated distribution, local training, aggregation, and redistribution until desired convergence. The nearest alternative instead concerns model training performed on a client using only that client's local data. Which concept should the reviewer select?
