Managing untraining of inference models with respect to portions of training data

Methods and systems for providing computer-implemented services using inference models are disclosed. To provide the computer-implemented services, a prototype inference model may be untrained with respect to a portion of training data that has sensitive and / or poisoned information content. To do so, a first partial untraining procedure may be performed to obtain a partially untrained prototype inference model. A testing procedure may be performed using a trusted inference model to determine whether the partially untrained prototype inference model has been sufficiently untrained with respect to the portion of training data and is sufficiently trained with respect to other training data that has an information content that is to be retained. If these conditions are met, the partially untrained prototype inference model may be promoted to a production ready inference model and used to provide the computer-implemented services.
