本文主要讨论了scala中Function和Method的主要异同点,当然Function做为Scala的重要概念,还有很多高阶用法,可以留待我们以后探讨学习。 Function和Method都是Scala中一段可以接收参数,进行计算并返回结果的可重用的代码块。 如果你想把这段代码块赋值给变量,亦或当作参数或者返回值传递的话,那就去用Function, 如果仅仅是为...

Whereas those one are the results for map (addColumnsViaMap method): When the number of columns increases, foldLeft is taking considerably more time. If we take the number of columns to 500 the result is similar (and more dramatic) Once again, for foldLeft : And for map: With 1000 column...
This talk will present a type-safe method for structuring LLM interactions based on Kyo effects, introducing an algebra of thoughts that simplifies complex AI workflows. We’ll demonstrate how this approach enables explicit modeling of AI capabilities, simpler management of LLM context, proper resource...
