Abstract: In one embodiment, a device trains, using feedback from a reference cohort of users of an online application, a prediction model to predict a quality of experience metric for the online application based on network telemetry. The device uses the prediction model to predict quality of experience metrics for different cohorts of users of the online application. The device makes one or more comparisons between performance metrics for the prediction model for the different cohorts of users, based on the quality of experience metrics predicted for the different cohorts of users. The device retrains, based on the one or more comparisons, the prediction model using feedback from the reference cohort and a particular cohort from among the different cohorts of users.

Abstract: In various embodiments, a device obtains a set of device classification rules. Each device classification rule specifies one or more attributes from a set of attributes and being configured to assign a device type to an endpoint in a network when the endpoint exhibits the one or more attributes specified by that rule. The device forms a graphical representation of the set of attributes. The device performs an analysis of the graphical representation of the set of attributes. The device provides a result of the analysis to a user interface.

Abstract: In one embodiment, a device associates one or more performance metrics with a particular session of an online application. The device makes a determination that a user of the online application associated with the particular session should be queried for feedback regarding their application experience. The device obtains, based on the determination, feedback from the user regarding their application experience, by causing a chatbot to be presented to the user and query the user for feedback regarding their application experience. The device associates the feedback from the user regarding their application experience with the one or more performance metrics.

Abstract: In one embodiment, a device obtains a first set of measurements of a path metric for a path in a network that are measured using periodic probing of the path. The device obtains a second set of measurements of the path metric for the path that are measured using fine-grained probing of the path at a higher frequency than that of the periodic probing. The device generates a predictive model that predicts values of the path metric, based on the first set of measurements and on the second set of measurements. The device causes, based on a value of the path metric predicted by the predictive model, traffic to be rerouted from the path to another path in the network.

Abstract: In one embodiment, a device obtains an indication of a network event predicted by a routing engine for a network. The device initiates monitoring of one or more network paths associated with the network event, to determine one or more states of the network. The device makes a comparison between the one or more states of the network and a set of one or more constraints. The device provides a prediction cancelation notification to the routing engine, based on the comparison.

Abstract: A dispenser for cosmetic, cleansing or pharmaceutical composition including a tubular sleeve for housing the whole of a movable sub-assembly in the storage position thereof in such a way that the head of the movable sub-assembly is not accessible. A locking mechanism prevents outward movement of the movable sub-assembly in the storage position relative to the sleeve. When a user axially depresses the head in the opposite direction to the outward direction, the locking mechanism releases the movable sub-assembly, which is urged outward by a spring at least as a position I which the head projects outward from the sleeve.

Abstract: The invention concerns a method for making adherent relief coating surface simulating the appearance of liquid droplets, comprising direct transfer application (and preferably by screen-printing) of a curable liquid material on the surface so as to form on the surface projecting discrete drops which are then cured: Drops of different sizes are applied, preferably in ordered manner.
