在pointwise中,采样的数据当做label为0的数据,同样,在pairwise中,采样的数据当做不太感兴趣的item来优化,数据集格式为(u,itrue,isample),如果采用bpr loss来优化,则D优化的是max(pos_score-neg_score),而G优化的max(neg_score-pos_score) , 其实这种GAN就是RSGAN,采用pairwise思想优化的GAN。 3. 如何训练G...

我在看amp for hardware这个repo的时候萌生了一个念头,对于motion piror作为reward这个事情上,对抗本身是必要的组件吗?如果我用别的loss替代它训练discriminator呢?现在我换成了RLHF的pairwise loss 好像也可以呢?或许再调调会更好,欢迎大家讨论(我觉得我越来越民科味道了)...
Efficient online learning with pairwise loss functions is a crucial component in building large-scale learning system that maximizes the area under the Receiver Operator Characteristic (ROC) curve. In this paper we investigate the generalization performance of online learning algorithms with pairwise loss...

To address this problem, we propose a novel loss paradigm termed Sparse Pairwise (SP) loss that only leverages few appropriate pairs for each class in a mini-batch, and empirically demonstrate that it is sufficient for the ReID tasks. Based on the proposed loss framework, we propose an ...
This paper proposes a new ensemble training using a Pairwise Adversarially Robust Loss (PARL) that by construction produces an ensemble of classifiers with diverse decision boundaries. PARL utilizes outputs and gradients of each layer with respect to network parameters in every classifier within the ...
Pairwise Cringe Loss is straightforward to implement and efficient to train, and we find it outperforms state-of-the-art preference optimization algorithms such as PPO and DPO on the AlpacaFarm benchmark. We show that iterations of training of our model are important for improved results, and ...
