摘要:

评估机器学习模型中的难度和偏差已经变得非常重要,因为当前的模型正在应用于现实世界的情况。在本文中,我们提出了一种简单的方法,用于计算基于训练过程中每个样本的损失累积的难度分数。我们称之为行动得分。我们提出的方法不需要对模型进行任何修改,也不需要任何外部监督,因为它可以作为从训练过程中收集信息的回调来实现。我们在两种不同的设置中测试和分析我们的方法:图像分类和目标检测,我们表明,在这两种设置中,动作得分可以提供有关模型和数据集偏差的见解。

英文摘要:

Evaluating difficulty and biases in machine learning models has become of extreme importance as current models are now being applied in real-world situations. In this paper we present a simple method for calculating a difficulty score based on the accumulation of losses for each sample during training. We call this the action score. Our proposed method does not require any modification of the model neither any external supervision, as it can be implemented as callback that gathers information from the training process. We test and analyze our approach in two different settings: image classification, and object detection, and we show that in both settings the action score can provide insights about model and dataset biases.
