Abstract: Disclosed in the present disclosure is a low-cost and zero-shot online log parsing method based on a large language model, including: firstly, extracting content of a log in a log message using regular expressions, then, performing regular expression matching with a log template in a database; if the matching is successful, updating a log sample corresponding to the log template; if the matching fails, conducting a dialogue with the large language model to obtain a new log template; performing template correction to prevent the log template generated by the large language model from being incapable of performing regular expression matching with the log message; performing template merging when a new template is generated; performing template splitting when the log sample is updated; and for all log templates to be added to the database, firstly, normalizing the log templates by post-processing, and then storing the log templates to the database.

Abstract: The present application discloses a method for detecting cigarette appearance defects based on variational Bayesian inference. In a cigarette appearance defect detection scenario, in order to solve the problem that a current point estimation-based machine learning algorithm leads to an overconfidence decision in a data scarcity area, the present application proposes a variational inference-based Bayesian method to improve a SSD backbone network, preferably including calculating a real posterior probability by the variational inference method, replacing a point estimation mechanism of a convolution layer weight in the original backbone network by using a form of probability distribution, then detecting the improved extracted features by an SSD target detection algorithm, and furthermore, accurately determining whether the appearance of the cigarette is defective and the type and location of the defect.

Abstract: In a method of making an electrode, a binder is dissolved in a solvent to form a solution. An Nb2O5 hydrate-based electrode material powder is suspended in the solution to form a slurry.
