论文摘要
黑色素瘤被认为是所有皮肤癌中最威胁性的。迫切需要建立可以帮助早期发现黑色素瘤并及时治疗患者的系统。最近的方法针对基于机器学习的系统,该系统将任务作为图像识别,将皮肤病变的皮肤镜图像标记为黑色素瘤或非黑色素瘤。即使这些方法在准确性方面显示出令人鼓舞的结果,但它们在训练上的计算非常昂贵,但质疑这些模型可在临床环境或内存约束设备中部署的能力。为了解决这个问题,我们专注于构建几乎没有层的简单和表现模型,而不到十个。以及更少的可学习参数,有206万(M),而使用知识蒸馏的425万(M)则具有从皮肤镜图像中检测黑色素瘤的目标。首先,我们使用Resnet-50训练教师模型来检测黑色素瘤。使用教师模型,我们训练称为蒸馏学生网络(DSNET)的学生模型,该模型使用知识蒸馏的参数约为0.26亿,其精度达到91.7%。我们将比较ImabiLeNet,VGG-16,Inception-V3,EdgitionNet-B0,Resnet-50和Resnet-101(Resnet-101)进行比较。我们发现,与其他预训练的模型相比,我们的方法在推理运行时效果很好,而2.57秒为14.55秒。我们发现,在黑色素瘤和非精度,召回和F1分数中,DSNET(0.26m参数)的表现较小15倍,始终如一地表现优于EfficityNet-B0(4M参数)(4M参数)。
Melanoma is regarded as the most threatening among all skin cancers. There is a pressing need to build systems which can aid in the early detection of melanoma and enable timely treatment to patients. Recent methods are geared towards machine learning based systems where the task is posed as image recognition, tag dermoscopic images of skin lesions as melanoma or non-melanoma. Even though these methods show promising results in terms of accuracy, they are computationally quite expensive to train, that questions the ability of these models to be deployable in a clinical setting or memory constraint devices. To address this issue, we focus on building simple and performant models having few layers, less than ten compared to hundreds. As well as with fewer learnable parameters, 0.26 million (M) compared to 42.5M using knowledge distillation with the goal to detect melanoma from dermoscopic images. First, we train a teacher model using a ResNet-50 to detect melanoma. Using the teacher model, we train the student model known as Distilled Student Network (DSNet) which has around 0.26M parameters using knowledge distillation achieving an accuracy of 91.7%. We compare against ImageNet pre-trained models such MobileNet, VGG-16, Inception-V3, EfficientNet-B0, ResNet-50 and ResNet-101. We find that our approach works well in terms of inference runtime compared to other pre-trained models, 2.57 seconds compared to 14.55 seconds. We find that DSNet (0.26M parameters), which is 15 times smaller, consistently performs better than EfficientNet-B0 (4M parameters) in both melanoma and non-melanoma detection across Precision, Recall and F1 scores
