Abstract: An exemplary system and method are provided for monitoring concept drift in a trained model, such as a chatbot. The system is configured to perform a method including receiving a first dataset representing model operations executed by the trained model; applying a data processing operation to the first dataset to determine a first result data of the first dataset; determining, based on the first result data, a difference between the first result data and a second result data; determining, based on the difference, whether concept drift has occurred; and in accordance with a determination that concept drift has occurred, transmitting an instruction to update training of the trained model. The exemplary system may be implemented as a drift detection system in communication with the trained model.

Abstract: A shaft assembly has a shaft and a journal bearing that is fixedly coupled to the shaft so that rotation of the shaft causes corresponding rotation of the journal bearing. A bearing race has an inner surface that defines a cylindrical bore and a lubrication groove that extends radially outward from the cylindrical bore. The journal bearing is rotatably disposed within the cylindrical bore of the bearing race.

Abstract: A shifter adjustment assembly can be configured to couple to a shifter of a tufting apparatus, the shifter having first, second, third, and fourth shaft segments. The shifter adjustment assembly comprises a first body that is configured to couple to respective first ends of the first and third shaft segments. A second body is configured to couple to respective first ends of the second and fourth shaft segments. The shifter assembly comprises a coupling between the first body and the second body. The coupling is configured to releasably secure an axial position of the first body with respect to the second body along the longitudinal dimension. The first body and second body define respective complementary surfaces that are configured for sliding engagement so that movement between the first body and the second body in the transverse dimension is restricted and movement between the first body and the second body in the longitudinal dimension is permitted.

Abstract: Systems and methods for generating and utilizing an interactive causal loop diagram using a causal loop designer are provided. In one or more examples, a computer-implemented method for creating a causal loop diagram comprising visually emphasized elements can comprise displaying a first element and a second element, wherein the first element and the second element comprise visually emphasizable elements. In response to receiving a user command to connect the first element to the second element, the method can comprise displaying a connection between the first element and the second element, wherein the connection comprises a visually emphasizable element. In one or more examples, the method comprises displaying a causal loop diagram comprising the first element, the second element, and the connection. In response to a user activating a visual emphasis tool, the method can comprise visually emphasizing one or more of the visually emphasizable elements.

Abstract: The present disclosure relates generally to storing computer models, and more specifically to a platform for achieving replicability of a computer model (e.g., a trained machine-learning algorithm) by storing and providing access to data associated with the computer model using an immutable and decentralized ledger system (e.g., a blockchain ledger) and a distributed database. An exemplary computer-enabled method for storing a computer model, the method comprises: receiving data associated with the computer model; generating one or more asset files based on the data associated with the computer model; generating one or more hash values corresponding to the one or more asset files; generating one or more of location trackers corresponding to the one or more asset files; generating a ledger entry comprising the one or more hash values and the one or more location trackers; and adding the ledger entry to a blockchain ledger.
