A reasoning method applied to a server, comprising: receiving a first request from a client; selecting a first sub-pool from a pool based on a similarity between the first request and at least one sub-pool in the pool, wherein the sub-pools in the pool are obtained by clustering historical requests, and at least one inference result of a historical request is contained in a sub-pool; and decoding the first request based on the first sub-pool to obtain a first inference result. In this way, by dividing the pool into multiple sub-pools and considering the association relationship between the subsequent request and the sub-pool, the subsequent request can use more accurate data to improve the reasoning quality. Meanwhile, by using the historical request to create the pool, the subsequent request does not need to re-construct the pool in the cold start stage, which improves the quality of the candidate word generated in the initial stage of the subsequent request, and the pool can be independent of the offline database.

An inference method, applied to a server, and comprising: receiving a first request from a client; on the basis of the similarity between the first request and at least one sub-pool comprised in a pool, selecting a first sub-pool from the pool, wherein the sub-pools in the pool are obtained by clustering historical requests, and one sub-pool comprises at least an inference result of one historical request; and on the basis of the first sub-pool, decoding the first request to obtain a first inference result. In this way, by dividing a pool into a plurality of sub-pools, and considering association relationships between subsequent requests and the sub-pools, the subsequent requests can use more accurate data, thereby improving inference quality. In addition, the pool is created by using historical requests, so that there is no need to recreate a pool for the subsequent requests in a cold start phase, thereby improving the quality of candidate tokens generated in an initial phase of the subsequent requests; and the pool may not depend on an offline database.

The invention relates to a clock synchronization method and device, computer equipment, a storage medium and a program product. The method comprises the following steps: acquiring a first counting result of a reference timer of a pulse per second signal at a first rising edge of the pulse per second signal and a second counting result of the reference timer at a first zero-crossing moment of a synchronous timer; determining a standard counting period of the second pulse signal according to the first counting result; and according to the initial phase difference between the second counting result and the first counting result and the standard counting period, performing clock synchronization on the synchronous counting period of the synchronous timer. According to the embodiment of the invention, the period value of the synchronous timer can be dynamically adjusted through the phase difference between the synchronous timer and the reference timer, so that the zero-crossing time of the synchronous timer is completely overlapped with the rising edge of the Beidou second pulse signal, and the accuracy of clock synchronization is improved.

The application belongs to the field of laser technology and application, and discloses an improved SPGD algorithm for a laser coherent synthesis system, which is used for solving the problem that the traditional SPGD algorithm cannot meet the bandwidth requirement of large-scale laser beam phase control. The operation mode of the algorithm is as follows: setting an initial phase control voltage and an initial gain coefficient; calculating the random disturbance voltage amplitude of this iteration; applying positive and negative random disturbance voltages satisfying Bernoulli distribution; according to the evaluation function value, dividing two cases, and performing corresponding segmented value on the gain coefficient; calculating the phase control voltage of each iteration; obtaining the updated system performance evaluation function value, and judging whether it converges or not, and if not, repeating the above steps until the algorithm converges. The improved SPGD algorithm can ensure the stability of the convergence process while improving the convergence speed of the laser beam phase tending to be consistent, and can be extended to coherent synthesis systems with different beam numbers without modifying any parameters, and is simple to operate and has strong universality.
