Abstract: Systems and methods are provided for implementing soft model assertions (SMA) system and techniques designed to monitor and improve Machine Learning (ML) model quality by to detecting errors within the one or more ML models. SMA techniques and systems are distinctly designed to leverage: 1) a user's ability to specify features over data; and 2) large, existing datasets of organizations, in a manner that can improve the accuracy and quality of predicting potential errors in Machine Learning (ML) models. A SMA system can include a controller device receiving predictions generated based on the ML models and output from the SMA system. The controller performs autonomous operations of the system in response to determining that the one or more detected errors within the one or more ML models yield a high certainty of errors in the predictions.

Abstract: A fiber optic ferrule has an entrance surface that is angled at an angle that other than perpendicular to the optical fiber axis. The optical fibers disposed within the fiber optic ferrule are preferably separated from the entrance surface. These features reduce the amount of reflection of the light back into the optical fiber and increase the performance of the fiber optic ferrule.
