Abstract: Provided is a lightweight model training method, an image processing method, a device and a medium. The lightweight model training method includes: acquiring first and second augmentation probabilities and a target weight adopted in an e-th iteration; performing data augmentation on a data set based on the first and second augmentation probabilities respectively, to obtain first and second data sets; obtaining a first output value of a student model and a second output value of a teacher model based on the first data set; obtaining a third output value and a fourth output value based on the second data set; determining a distillation loss function, a truth-value loss function and a target loss function; training the student model based on the target loss function; and determining a first augmentation probability or target weight to be adopted in an (e+1)-th iteration in a case of e is less than E.

Abstract: Multifunctional coatings and chemical additives, comprising of lubricant, micro/nano-textured particles, emulsifiers, hydrogel polymers, cross-linking agent to modify the hydrogel polymers, antimicrobial to preserve the bio-based materials, and water solvent, are useful in hydraulic fracturing operation either directly applied on the surface of proppants, or/and mixed with other friction reducer additives to totally or partially substitute the regular friction reducer chemicals, alternatively, as additive components blended or mixed into regular fracturing fluid for easily pumping proppants downhole and stabilizing the pumping pressure; beneficial to the well productivity, effectively suppress and mitigate the risk of respirable microcrystalline dust as the coated materials are transported and handled in the manufacturing plant, terminal, and oil application fields without a need for drying operation on the coating products.
