Data structure and algorithm-One

右边界左边界 函数式编程 传统的实现方式通常是将具体的功能代码直接写在方法内部。这样的实现方式对于固定的功能来说可能是足够的,但它的灵活性和复用性较低。每当需要不同的功能时,您需要编写新的方法或修改原有方法,这可能会导致代码的冗余和不易维护。 而函数式编程的优点在于它将函数本身作为参数传递,使得调用 ......

【翻译】为什么我们需要极限和无穷小?(Why Do We Need Limits and Infinitesimals?)

那么多数学课,没有任何上下文,就跳到极限,无穷小,非常小的数(T)。但是我们为什么要在乎呢?数学帮助我们模拟世界。我们可以把一个复杂的想法(一条蜿蜒的曲线)分解成更简单的部分(矩形): ![image](https://img2023.cnblogs.com/blog/2469253/202308/ ......

Hybrid-SORT起飞 | 超过DeepSORT将近10个点的多目标跟踪香不香?

前言 多目标跟踪(MOT)旨在在帧间检测和关联所有所需的目标。大多数方法通过明确或隐式地利用强大的线索(即空间和外观信息)来完成任务,这些线索表现出强大的实例级别判别能力。然而,当出现目标遮挡和聚类时,由于目标之间的高度重叠,空间和外观信息同时变得模糊不清。在本文中,作者证明MOT中这个长期以来的挑 ......

hive 的order by ,sort by,distribute by,cluster by

order by order by会对输入做全局排序,因此只有一个Reducer(多个Reducer无法保证全局有序),然而只有一个Reducer,会导致当输入规模较大时,消耗较长的计算时间,在生产环境中遇到数据量较大的情况,一般无法成功。 sort by sort by不是全局排序,其在数据进入r ......
