Abstract: The disclosure herein describes training a document recommendation model using loss data generated from a linear score difference vector. A training data entry is provided including a query and a set of candidate documents. A document recommendation model generates a set of document prediction scores indicative of a likelihood that the candidate documents are responses to the query and a pairwise score difference matrix is generated using the set of document prediction scores. The pairwise score difference matrix is transformed into a score difference vector using a correct document vector that indicates a correct document among the set of candidate documents. Loss data of the document recommendation model is generated using the score difference vector and the document recommendation model is adjusted using the calculated loss data. Training the document recommendation model based on the linear score difference vector reduces resource usage when compared to training with a difference matrix.

Abstract: A telescopic tube assembly includes a first tube and a second tube penetrated in the first tube. A handle is pivoted to a base sleeved on the first tube and pressed against the second tube when the handle is locked. Further, a pin is provided between the base and a cover mounted to the base, and a button is horizontally disposed in the base. When the button is pressed, the pin is pushed by the button to be disengaged from the second tube, such that the length of the second tube can be adjusted. When the button is released, the pin is pushed by an elastic member to be engaged with the second tube for locking the second tube in a desired length. By means of the dual lock design, the telescopic tube assembly of the present invention provides good positioning effect to reduce operational risk.

Abstract: A booster additive concentrate may advantageously contain: (a) an anti-wear mixture of two or more phosphite/phosphate compounds and one or more ether/thioether compounds; (b) an ashless dispersant; (c) a calcium-containing detergent, such as an overbased calcium phenate; (d) ?2 friction modifiers, at least one of which comprises a polyalkylene polyamine succinimide derivative; (e) optionally a corrosion inhibitor; and (f) a lubricating oil basestock. Based on these additive components, the booster additive concentrate may exhibit specific contents of B/Ca/P and may contain minimal or substantially no additional antioxidants. Lubricant compositions can be made from the booster additive concentrates and a fresh/used lubricant oil composition “diluent,” which can rejuvenate the diluent. Such lubricant compositions can have advantageous anti-shudder durability (ASD) lifetimes and other frictional properties.
