Abstract: Machine learning models may be generated that are compatible with another machine learning model and satisfy a resource constraint. Techniques that ensure weight compatibility and architectural compatibility between a machine learning model being created to be compatible with another machine learning model are applied. The resource constraint is enforced so that the generated machine learning model also fits within the resource constraint.

Abstract: Techniques for generating recommendations for redistributing product inventories are disclosed. A product redistribution system applies hierarchal prioritization of product locations to generate a plan for redistributing products among the product locations. A system identified product repositories organized into clusters. A product redistribution plan first redistributes products among repositories within a cluster. Then the system redistributes products between different clusters. A system predicts whether repositories have excess products or product shortages by applying product excess windows and product shortage windows to inventory data. The system predicts supply and demand of a product over a period of time including the product supply window and the product shortage window. The system generates the product redistribution plan based on the predicted product excess predictions and product shortage predictions.

Abstract: A pickleball paddle having a replaceable face sheet includes a paddle body. The paddle body has a paddle face portion, a handle portion connected to the paddle face portion, and a paddle core inside the paddle face portion. In practical applications, the user may select different face sheets with different hitting effects to be attached to two accommodation cavities of the paddle body according to his/her needs. The user may choose to replace a desired face sheet, thereby realizing the replacement of the face sheet of the pickleball paddle. This improves the flexibility of the pickleball paddle and is environmentally friendly and cost-effective.

Abstract: The disclosure discloses the preparation of thermophilic ?-glucosidase and the application thereof, which belongs to the technical field of genetic engineering and fermentation engineering. The present disclosure heterologously expresses the ?-glucosidase TpBgl3A derived from thermophilic fungus Talaromyces piceae by constructing a recombinant bacteria. The enzyme production of recombinant bacteria can reach 2324 U/mL in a 3.6 L fermenter. The resulting ?-glucosidase TpBgl3A can produce gentioligosaccharides with a high conversion rate using glucose as a substrate at a lower enzyme amount added, which significantly reduces production costs. In the reaction system using glucose and cellobiose as substrates, the conversion rate of gentioligosaccharide reaches 26.2%, which has the potential for industrial production of gentioligosaccharide.
