  • Publication number: 20180285957
    Abstract: A recommendation system associated with an online marketplace can generate recommendations pertaining to users and assets of the online marketplace by computing user-asset propensity scores. The recommendation system can compute a corresponding user-asset propensity score for each unique user-asset combination. Based on the scores, recommendations indicating predicted user behavior can be generated. To generate the user-asset propensity scores, the recommendation system can generate machine-learned models based on training data. The model can comprise a plurality of classifiers each being associated with user-asset attributes.

  • Patent number: 9198597
    Abstract: Kits and methods for the treatment of certain types of cancers, specifically various primary brain cancers. In some embodiments, treatment is directed toward the known areas of cancer cell infiltration and along pathways of likely migration ahead of established areas of cancer cell infiltration. In some embodiments, cancer cells are targeted where they have likely spread, but yet remain undetected. Some embodiments relate to a means of automatically directing radiological analysis along likely pathways of cancer cell migration to precisely determine the extent of detectable cancer spread. In some embodiments, treatments are directed to a predetermined distance along such pathways.

  • Publication number: 20070050216
    Abstract: The present invention provides systems and methods to realize the potential benefit of portable storage devices by taking advantage of standard PCs including an optical disk drive capable of reading an optical disk, such as a CD or a DVD, cost effective optical disks, and the Internet. In a preferred embodiment, an individual patient provides personal data to a healthcare service center. The healthcare service center then creates a portable optical disk for the patient to carry, if he/she so desires. The personal data that is written onto the portable optical disk is stored on a database management server database and is readable and updateable by the individual patient using his/her PC with an optical disk drive and connected to the Internet. The individual patient can choose to update his/her personal data on the portable optical disk and can receive a new portable optical disk that includes the update.

  • Patent number: 6900740
    Abstract: A vehicle safety and control system provides early warning and includes a network including a plurality of remotely located modules disposed along a vehicle pathway. Each module is communicably connected to at least one of the other modules. The modules include a measurement system including at least one sensor for obtaining sensor data. The sensor data provides position and velocity data for objects proximate thereto. The modules also include an illuminated display having a plurality of observable distinct states, the observable states including states relating to the sensor data.
