Recently, standard benchmark databases and evaluation campaigns have been created allowing a quantitative comparison of CB IR systems. These benchmarks allow the comparison of image retrieval systems under different aspects:usability and user interfaces, C Ombination with text retrieval, or overall performance of a system. 1.

First, design and planning1. The first step in planning a benchmark is to ask questions, clear the document, and then decide whether to use standard benchmarks or design specific tests.2. Even if you do not need to create a dedicated benchmark test, it is also necessary to write down the test plan in detail.3. Specifications should be established to document the parameters and results, and each test must be

Recently, in a colleague's question: when iterating over a slice, it would be better to move the loop condition out of the loop for len than the Golang compiler's optimization results.
That
func G0(a []int) int { L := Len(a) for I := 0; I L; I++ { } return 1}
Whether it will be better than
