The application of large language models in server environments during the AI era, especially in the inference phase, presents numerous opportunities. AI can be divided into two main stages: training and inference. From pre-training to fine-tuning and reinforcement, a general large model is developed, which is then used to generate application models; the inference side … Read more
1. Choose Appropriate Algorithms and Data Structures Selecting a suitable data structure is crucial. If there are many insertions and deletions in a collection of randomly stored numbers, using a linked list is much faster. Arrays and pointer statements are closely related; generally, pointers are more flexible and concise, while arrays are more intuitive and … Read more
