Reprint: TransXNet: A new CNN-Transformer visual backbone that aggregates global and local information, with powerful performance!

Article address: https://arxiv.org/abs/2310.19380</code><code>Project address: https://github.com/LMMMEng/TransXNet 00 | Introduction Current situation: Recent research integrates convolutions into transformers to introduce inductive bias and improve generalization performance. (1) The static characteristics of traditional convolution make it unable to dynamically adapt to input changes, resulting in a representation difference between convolution and self-attention, because self-attention dynamically calculates the attention […]

Supports HTTP/2 and SPDY: OkHttp supports the latest HTTP protocol versions, including HTTP/2 and SPDY, to provide faster and more efficient network communication. Connection […]

[Server-side performance test] Performance test implementation process!

Performance testing uses automated testing tools to simulate a variety of normal, peak, and abnormal load conditions to test various performance indicators of the system. My definition of performance testing clearly describes the methods and processes of performance testing: Performance testing aims at system performance indicators, establishes performance testing models, formulates performance testing plans, develops […]

postgresql|database|materialized view analysis to improve query performance

Foreword: We generally think that the digital world is a virtual world, OK, but in fact some of our needs are exactly the same as those in the real world. For example, for databases, especially relational databases, we hope that the databases we use can be faster (query speed) , higher (higher performance limit), stronger […]

[c++] In-depth analysis of your favorite stringstream and snprintf performance

I recently wrote two similar modules in a program. One uses snprintf to output intermediate data, and the other uses stringstream lazily. And guess what? The frame is actually pressed! ! Who is holding back performance? Performance analysis experiment from Alibaba Cloud I searched online and found that someone had done a performance analysis experiment. […]
