An interpretable imbalanced semi-supervised deep learning framework for improving differential diagnosis of skin diseases
Dermatological diseases are among the most common disorders worldwide. This
paper presents the first study of the interpretability and imbalanced
semi-supervised learning of the multiclass intelligent skin diagnosis framework
(ISDL) using 58,457 skin images with 10,857 unlabeled samples. Pseudo-labelled
samples from minority classes have a higher probability at each iteration of
class-rebalancing self-training, thereby promoting the utilization of unlabeled
samples to solve the class imbalance problem. Our ISDL achieved a promising
performance with an accuracy of 0.979, sensitivity of 0.975, specificity of
0.973, macro-F1 score of 0.974 and area under the receiver operating
characteristic curve (AUC) of 0.999 for multi-label skin disease
classification. The Shapley Additive explanation (SHAP) method is combined with
our ISDL to explain how the deep learning model makes predictions. This finding
is consistent with the clinical diagnosis. We also proposed a sampling
distribution optimisation strategy to select pseudo-labelled samples in a more
effective manner using ISDLplus. Furthermore, it has the potential to relieve
the pressure placed on professional doctors, as well as help with practical
issues associated with a shortage of such doctors in rural areas
A Study on Deep Learning Methods for Skin Disease Classification
Dermatological disorders are one among the foremost widespread diseases within the world. Despite being common its diagnosis is extremely difficult due to its complexities of skin tone, color, presence of hair. This paper provides an approach to use various computer vision-based techniques (deep learning) to automatically predict the varied sorts of skin diseases. The system makes use of deep learning technology to coach itself with the varied skin images. the most objective of this technique is to realize maximum accuracy of disease of the skin prediction. The people health quite the other diseases. Skin diseases are mostly caused by mycosis, bacteria, allergy, or viruses, etc. The lasers advancement and Photonics based medical technology is employed in diagnosis of the skin diseases quickly and accurately. The medical equipment for such diagnosis is restricted and costliest. So, Deep learning techniques helps in detection of disease of the skin at an initial stage. The feature extraction plays a key role in classification of skin diseases. The usage of Deep Learning algorithms has reduced the necessity for human labor, like manual feature extraction and data reconstruction for classification purpose
DermX: an end-to-end framework for explainable automated dermatological diagnosis
Dermatological diagnosis automation is essential in addressing the high
prevalence of skin diseases and critical shortage of dermatologists. Despite
approaching expert-level diagnosis performance, convolutional neural network
(ConvNet) adoption in clinical practice is impeded by their limited
explainability, and by subjective, expensive explainability validations. We
introduce DermX and DermX+, an end-to-end framework for explainable automated
dermatological diagnosis. DermX is a clinically-inspired explainable
dermatological diagnosis ConvNet, trained using DermXDB, a 554 image dataset
annotated by eight dermatologists with diagnoses, supporting explanations, and
explanation attention maps. DermX+ extends DermX with guided attention training
for explanation attention maps. Both methods achieve near-expert diagnosis
performance, with DermX, DermX+, and dermatologist F1 scores of 0.79, 0.79, and
0.87, respectively. We assess the explanation performance in terms of
identification and localization by comparing model-selected with
dermatologist-selected explanations, and gradient-weighted class-activation
maps with dermatologist explanation maps, respectively. DermX obtained an
identification F1 score of 0.77, while DermX+ obtained 0.79. The localization
F1 score is 0.39 for DermX and 0.35 for DermX+. These results show that
explainability does not necessarily come at the expense of predictive power, as
our high-performance models provide expert-inspired explanations for their
diagnoses without lowering their diagnosis performance
Artificial Intelligence in Skin Cancer: A Literature Review from Diagnosis to Prevention and Beyond
Artificial Intelligence (AI) in medicine is quickly expanding, offering significant potential benefits in diagnosis and prognostication. While concerns may exist regarding its implementation, it is important for dermatologists and dermatopathologists to collaborate with technical specialists to embrace AI as a tool for enhancing medical decision-making and improving healthcare accessibility. This is particularly relevant in melanocytic neoplasms, which continue to present challenges despite years of experience. Dermatology, with its extensive medical data and images, provides an ideal field for training AI algorithms to enhance patient care. Collaborative efforts between medical professionals and technical specialists are crucial in harnessing the power of AI while ensuring it complements and enhances the existing healthcare framework. By staying informed about AI concepts and ongoing research, dermatologists can remain at the forefront of this emerging field and leverage its potential to improve patient outcomes. In conclusion, AI holds great promise in dermatology, especially in the management and analysis of Skin cancer (SC).
In this review we strive to introduce the concepts of AI and its association with dermatology, providing an overview of recent studies in the field, such as existing applications and future potential in dermatology
Computer-Aided Diagnosis for Melanoma using Ontology and Deep Learning Approaches
The emergence of deep-learning algorithms provides great potential to enhance the prediction performance of computer-aided supporting diagnosis systems. Recent research efforts indicated that well-trained algorithms could achieve the accuracy level of experienced senior clinicians in the Dermatology field. However, the lack of interpretability and transparency hinders the algorithms’ utility in real-life. Physicians and patients require a certain level of interpretability for them to accept and trust the results. Another limitation of AI algorithms is the lack of consideration of other information related to the disease diagnosis, for example some typical dermoscopic features and diagnostic guidelines. Clinical guidelines for skin disease diagnosis are designed based on dermoscopic features. However, a structured and standard representation of the relevant knowledge in the skin disease domain is lacking.
To address the above challenges, this dissertation builds an ontology capable of formally representing the knowledge of dermoscopic features and develops an explainable deep learning model able to diagnose skin diseases and dermoscopic features. Additionally, large-scale, unlabeled datasets can learn from the trained model and automate the feature generation process. The computer vision aided feature extraction algorithms are combined with the deep learning model to improve the overall classification accuracy and save manual annotation efforts
Investigating the Quality of DermaMNIST and Fitzpatrick17k Dermatological Image Datasets
The remarkable progress of deep learning in dermatological tasks has brought
us closer to achieving diagnostic accuracies comparable to those of human
experts. However, while large datasets play a crucial role in the development
of reliable deep neural network models, the quality of data therein and their
correct usage are of paramount importance. Several factors can impact data
quality, such as the presence of duplicates, data leakage across train-test
partitions, mislabeled images, and the absence of a well-defined test
partition. In this paper, we conduct meticulous analyses of two popular
dermatological image datasets: DermaMNIST and Fitzpatrick17k, uncovering these
data quality issues, measure the effects of these problems on the benchmark
results, and propose corrections to the datasets. Besides ensuring the
reproducibility of our analysis, by making our analysis pipeline and the
accompanying code publicly available, we aim to encourage similar explorations
and to facilitate the identification and addressing of potential data quality
issues in other large datasets.Comment: 36 pages, 8 figures, 3 table
Facial Skin Disease Detection using Image Processing
Busy lifestyle, modernization, increasing pollution and unhealthy diet have led to problems which people are neglecting. Not drinking enough water, stress and hormonal changes are causing problems to skin. Causes may be situational or genetic. Few skin conditions are minor while others can be life-threatening. The skin is the largest organ of the body and is composed of water, proteins, fats and minerals. Problems appear on outer layer of the skin that is epidermis. Skin diseases are considered to be the fourth most common cause of human illness. Skin diseases are observed to increase with age and were seen frequently in both men and women. Skin disorders can be temporary or permanent. Skin diseases have an impact on individual, family and social life caused by inadequate self-treatment which may also induce psychological problems. In recent years, use of computer technologies is becoming practically universal for both personal and professional issues. Facial skin problem identification and recognition has evolved to a great extent over the years. Detection of skin diseases is done using Convolution Neural Network (CNN) and image processing methods. CNN yields better performance in terms of accuracy, precision and results than the existing conventional methods. Image processing uses digital computer to process the images through an algorithm. We focus on features like skin tone, skin texture and color. We present a brief review about various facial skin problems providing more insight about the effective models and algorithms used
