Abstract: In one embodiment, a supervisory service for a software-defined wide area network (SD-WAN) uses a plurality of different decision thresholds for a machine learning-based classifier, to predict tunnel failures of a tunnel in the SD-WAN. The supervisory service captures performance data indicative of performance of the classifier when using the different decision thresholds. The supervisory service selects, based on the captured performance data, a particular decision threshold for the classifier, in an attempt to optimize the performance of the classifier. The supervisory service uses the selected decision threshold for the classifier, to predict a tunnel failure of the tunnel.

Abstract: Disclosed are example machine-learning approaches for determining maturity metrics of chatbot users. One or more datasets with words used during past conversations between a chatbot and a set of users with known maturity metrics are generated. A machine learning model is trained by applying machine learning to the one or more datasets such that the machine learning model is trained to output maturity metrics based on words received as inputs. A set of words or phrases spoken or written by the user during a conversation is fed to the machine learning model to determine a maturity metric of the user. A response is identified based on the determined maturity metric, and the response is presented during the conversation with the user. Words and phrases of a user conversing with a chatbot are used to determine the user's age or another maturity metric to generate responses that enhance the user experience.

Abstract: A computer-implemented method for seamlessly performing a maintenance operation on a stateful system includes mapping a network address of the stateful system to a primary server that uses a primary database to respond to incoming data requests. In response to receiving a maintenance request, the primary database is replicated to a secondary database of a secondary server. The secondary server is updated according to the maintenance request. The method further includes caching, in a replay buffer of the primary server, incoming data requests during the replicating. After the replicating, the data requests from the replay buffer are executed by the secondary server. Write operations to the primary server are disabled during the replicating, and the network address of the stateful system is mapped to the secondary server. Subsequently, the primary server is updated and reinstated by mapping the network address, and enabling the write operations.
