WebFeb 21, 2024 · 使用 PyTorch 中的 torch.topk 函数选择距离最近的 k 个训练数据,使用 torch.bincount 函数计算 k 个训练数据的标签的出现次数,使用 torch.argmax 函数选择出现次数最多的标签作为预测标签。 在测试阶段,使用测试数据计算预测标签,并计算模型的准 … WebThe problem is cross-entropy requires targets tensor to contain values b.w. 0 to C-1. And in dice loss, targets need to be one-hot encoded. So I chose to apply torch.argmax on targets (which is already one-hot encoded) to find cross-entropy loss. But I saw somewhere that torch.argmax is not differentiable, though I only use it on targets.
