Deep learning system have drawback that their output is not accompanied with ex-planation. In a domain such as forensic handwriting verification it is essential to provideexplanation to jurors. The goal of handwriting verification is to find a measure of confi-dence whether the given handwritten samples are written by the same or different writer.We propose a method to generate explanations for the confidence provided by convolu-tional neural network (CNN) which maps the input image to 15 annotations (features)provided by experts. Our system comprises of: (1) Feature learning network (FLN),a differentiable system, (2) Inference module for providing explanations. Furthermore,inference module provides two types of explanations: (a) Based on cosine similaritybetween categorical probabilities of each feature, (b) Based on Log-Likelihood Ratio(LLR) using directed probabilistic graphical model. We perform experiments using acombination of feature learning network (FLN) and each inference module. We evaluateour system using XAI-AND dataset, containing 13700 handwritten samples and 15 cor-responding expert examined features for each sample. The dataset is released for publicuse and the methods can be extended to provide explanations on other verification taskslike face verification and bio-medical comparison. This dataset can serve as the basis and benchmark for future research in explanation based handwriting verification. The code is available on github.
MSDS: A Large-Scale Chinese Signature and Token Digit String Dataset for Handwriting Verification

尽管在线手写识别技术近年来取得了很大的进展,但由于数据集规模小,生物识别介质有限,其识别性能与实际应用相比仍有很大差距。因此,本文提出了一个新的手写验证基准数据集--多模态签名和数字串数据集(Multimodal Signature and Digit String,MSDS),该数据集由402个用户提供的两个子集组成:中文签名(MSDS-ChS)和令牌数字串(MSDS-TDS),每个子集包含20个真实样本和20个熟练的专家。MSDS-ChS由手写的中文签名组成,据我们所知,这是最大的公开可用的手写验证中文签名数据集,至少是现有在线数据集的八倍。同时,MSDS-TDS由手写的令牌数字串组成,即用户的实际电话号码,尚未被探索。分别对MSDS-ChS和MSDS-TDS进行了不同基线的广泛实验。令人惊讶的是,最先进的方法在MSDS-TDS上的验证性能通常优于MSDS-ChS,这表明手写令牌数字串可能是一种比手写中文签名更有效的生物特征。这是一个很有希望的发现,可以激励我们探索新的生物特征。MSDS数据集可在https://github.com/HCIILAB/MSDS上获得。
