  • Patent number: 10713598
    Abstract: A server of a transportation network determines characteristics of trips provided to users, as well as the usage of the services by users. Using the determined characteristics, the server trains a model that, for a given set of trips for a user, estimates a degree of likely user dissatisfaction with the trips. Based on the estimated degree of user dissatisfaction, the system can estimate user dissatisfaction in real time, directly after completion of a trip, and can take remedial actions should the user be estimated to be likely dissatisfied.

  • Publication number: 20200065126
    Abstract: Disclosed are various embodiments for distributing the load of a plurality of virtual machines across a plurality of hosts. A potential new host for a virtual machine executing on a current host is identified. A gain rate associated with migration of the virtual machine from the current host to the potential new host is calculated. A gain duration associated with migration of the virtual machine from the current host to the potential new host is also calculated. A migration cost for migration of the virtual machine from the current host to the potential new host, the migration cost being based on the gain rate and the gain duration is determined. It is then determined whether the migration cost is below a predefined threshold cost. Migration of the virtual machine from the current host to the optimal host is initiated in response to a determination that the migration cost is below the predefined threshold.

    Abstract: In one embodiment, a method includes accessing user-concept scores for a first set of users, wherein each user-concept score is associated with a user-concept pair; calculating recommended user-concept scores for a subset of user-concept pairs in a second set of users. The first set of users may be discrete from the second set of users. A recommendation-algorithm may compute the recommended user-concept scores for a user-concept pair by optimizing an objective function comprising a plurality of predicted rating functions. Each predicted rating function may be determined using a user score, a concept score, a user-bias value associated with the user, as well as a concept-bias value associated with the concept. Finally, the method may include sending recommendations for one or more concepts based on the recommended user-concept scores for the second set of users.

  • Patent number: 10355661
    Abstract: A power delivery network, circuit, and method reduce die package resonance of an integrated circuit (IC) die. Decoupling capacitors interact with equivalent series inductances (ESLs) of power conductors within a package carrier substrate create the die package resonance characteristic. In one form, an anti-resonance tuning circuit has a first node conductively coupled to one of the IC die's positive or negative power supply conductors, and a second node conductively coupled directly to a selected conductive structure on the carrier substrate. The anti-resonance tuning circuit includes a tuning capacitor, a tuning inductor, and optionally a dampening resistor coupled in series and having values sufficient to mitigate the die package resonance. In another form, impedance adjustment techniques are provided to connect and tune the anti-resonance tuning circuit to lower an impedance peak.
