YOLOV3的损失函数在YOLOV2的基础上,用多个独立的逻辑回归损失代替了YOLOV2里面的softmax损失,然后去掉了对Anchor在前12800次训练轮次中的回归损失,也即是YOLOV2损失函数的第二项。另外新增了一个ignore_thresh参数来忽略一些和GT box的IOU大于ignore_thresh的预测框的objectness损失。除了以上细节,其它部分和YOLOV2的处理...
Timsort - A templated stable sorting function which outperforms quicksort-based algorithms including std::sort, for reversed or semi-sorted data. [MIT] Indiesort - A sort wrapper which enables the use of std::sort (& other random-access sort functions) with non-random-access containers, and...
F Features removed when the /std:c++17 or later compiler option is specified. To re-enable these features (to ease the transition to newer language modes), use these macros: _HAS_AUTO_PTR_ETC, _HAS_FUNCTION_ALLOCATOR_SUPPORT, _HAS_OLD_IOSTREAMS_MEMBERS, and _HAS_UNEXPECTED. G C++17's ...

3.CAS(Compare-and-Swap)操作 为了进一步提高并发性能,ConcurrentHashMap在插入元素、更新数据时,采用了CAS操作。这是一个原子性操作,能够确保在多个线程同时访问相同元素时,只有一个线程能够成功更新数据。 具体来说,ConcurrentHashMap在进行插入、更新时,会通过CAS检查当前值是否被其他线程修改过。如果没有被修改,它会...
