  • Patent number: 12218957
    Abstract: In an approach, a processor receives a set of normal domains, a set of suspicious domains, and a set of malicious domains; labels each domain of the set of normal domains as normal producing a labelled set of normal domains and each domain of the set of suspicious domains and the set of malicious domains as malicious producing a labelled set of malicious domains; samples a preset percentage of the labelled set of normal domains producing a sampled set of normal domains; aggregates the sampled set of normal domains and the labelled set of malicious domains producing a set of aggregated domains; filters the set of aggregated domains using hit size, inter-arrival-time, and univariate volumetric filters producing a set of filtered domains; and determines a cluster of a set of clusters to which each of the set of filtered domains is to be assigned using a trained K-shape model.

  • Publication number: 20240420470
    Abstract: Techniques are described with regard to automatic machine configuration in a workspace environment. An associated computer-implemented method includes collecting workspace activity data in a workspace environment including at least one machine, wherein the workspace activity data is collected at least in part via a plurality of video frames captured by a plurality of video cameras and via a plurality of audio segments captured by at least one microphone. The method further includes configuring at least one workspace positioning artificial neural network based upon analysis of the workspace activity data, applying the at least one workspace positioning artificial neural network to derive at least one human activity datapoint in the workspace environment, and automatically configuring the at least one machine based upon the at least one human activity datapoint.

  • Publication number: 20240148818
    Abstract: The invention relates to an ophthalmic pharmaceutical composition and its preparation methods and applications, wherein the pharmaceutical composition comprises of L-Alanyl-L-Glutamine suspended or dissolved in an isoosmotic solution suitable for human eyes, and has the advantages causing minimal irritation, with high stability and a good safety profile, and which can be used for relieving dry eye disease (DED) symptoms and/or improving and/or treating DED.
