  • Publication number: 20240140107
    Abstract: A heat transfer roller apparatus is disclosed and configured for transferring an at least one design onto a substrate. In at least one embodiment, with the substrate sandwiched between a support frame and a support base of the apparatus, and a heat transfer compatible transfer sheet containing the at least one design positioned on the substrate within a frame boundary defined by the support frame, an at least one heat roller traverses across the transfer sheet—from a first end of the support frame to an opposing second end of the support frame—at a predetermined temperature, pressure and traversal time as set by a controller of the apparatus, so as to cause the at least one design on the transfer sheet to bond to the substrate, with a carrier of the apparatus subsequently separating the transfer sheet from the substrate while the transfer sheet is still hot.

  • Patent number: 11829496
    Abstract: One embodiment provides for a method for evaluation of an artificial intelligence (AI) service, the method includes partitioning, by a processor, data into in-domain data and out-of-domain data. The processor defines held-out data from both of the in-domain data and the out-of-domain data for evaluation by each of domain and sub-domain based on building a taxonomy of both domains and sub-domains for the AI service. The held-out data is excluded from training data used for training the AI service. The processor further determines distribution underlying performance metrics for the held-out data using bootstrap validation processing. The processor also determines performance guarantees for multiple settings conditioned on multiple characteristics of an application scenario for the held-out data of the taxonomy based on the underlying performance metrics.
