Patent number: 11699434Abstract: Embodiments provide for improved data sequence validity processing, for example to determine validity of sentences or other language within a particular language domain. Such improved processing is useful at least for arranging data sequences based on determined validity, and/or making determinations and/or performing actions based on the determined validity. A determined probability (e.g., transformed into the perplexity space) of each token appearing in a data sequence is used in any of a myriad of manners to perform such data sequence validity processing. Example embodiments provide for generating a perplexity value set for each data sequence in a plurality of data sequences, generating a probabilistic ranking set for the plurality of data sequences based on the perplexity value sets and at least one sequence ranking metric, and generating an arrangement of the plurality of data sequences based on the probabilistic ranking set.Type: GrantFiled: December 4, 2020Date of Patent: July 11, 2023Assignee: ARRIA DATA2TEXT LIMITEDInventors: Daniel da Silva De Paiva, Gowri Somayajulu Sripada, Craig Thomson

The second conduit extends between a gas inlet (56) and a gas outlet (57), the gas outlet being located in proximity to the powder outlet such that a gas flowing through the second conduit and out of the gas outlet produces a suction force at the powder outlet to promote flow of a dry powder through the first conduit and out of the powder outlet and the nozzle outlet. The powder outlet and the gas outlet are orientated to promote mixing of the gas with the dry powder. The first conduit (52) is a straight conduit between the powder inlet (54) and the powder outlet (55).Type: ApplicationFiled: February 2, 2022Publication date: August 18, 2022Inventors: Sabina BURMESTER, Thomas HOTCHKISS, David MARVELL, Craig THOMSON
