摘要:

目前,每54名儿童中就有1名被诊断患有自闭症谱系障碍(ASD),比2000年高出178%。早期诊断和治疗可以显着增加脱离频谱和完全康复的机会。由于有许多针对神经和沟通技能的身体和行为测试,诊断ASD非常复杂,主观,耗时且昂贵。我们假设使用机器学习分析面部特征和社会行为可以加快ASD的诊断,而不会影响现实世界的表现。我们建议开发一种混合架构,使用分类数据和图像数据来自动化传统的ASD预筛选,这使得诊断更快,更容易。我们为模块1创建并测试了Logistic回归模型和线性支持向量机,该模型对ADOS分类数据进行分类。卷积神经网络和DenseNet网络用于模块2,其对视频数据进行分类。最后,我们使用三种数据平均策略组合了性能最好的模型,线性SVM和DenseNet。我们使用标准平均值,基于训练数据的数量加权,并基于训练数据中ASD患者的数量加权,以平均结果,从而提高临床应用的准确性。我们得到的结果支持我们的假设。我们的新架构能够有效地自动化ASD预筛选,最大加权准确率为84%。

英文摘要:

Currently, every 1 in 54 children have been diagnosed with Autism Spectrum Disorder (ASD), which is 178% higher than it was in 2000. An early diagnosis and treatment can significantly increase the chances of going off the spectrum and making a full recovery. With a multitude of physical and behavioral tests for neurological and communication skills, diagnosing ASD is very complex, subjective, time-consuming, and expensive. We hypothesize that the use of machine learning analysis on facial features and social behavior can speed up the diagnosis of ASD without compromising real-world performance. We propose to develop a hybrid architecture using both categorical data and image data to automate traditional ASD pre-screening, which makes diagnosis a quicker and easier process. We created and tested a Logistic Regression model and a Linear Support Vector Machine for Module 1, which classifies ADOS categorical data. A Convolutional Neural Network and a DenseNet network are used for module 2, which classifies video data. Finally, we combined the best performing models, a Linear SVM and DenseNet, using three data averaging strategies. We used a standard average, weighted based on number of training data, and weighted based on the number of ASD patients in the training data to average the results, thereby increasing accuracy in clinical applications. The results we obtained support our hypothesis. Our novel architecture is able to effectively automate ASD pre-screening with a maximum weighted accuracy of 84%.
