When it comes to machine learning with Golang, you are limited to training the existing models. Tutorials, references, and examples are constantly reviewed to avoid errors, but we cannot warrant full correctness of all content. Concurrency refers not only to CPU parallelism, but also to asynchrony: letting slow operations like a database or network read run while the program does other work, as is common in event-based servers.
