Multi-Stage Classification of Retinal OCT Using Multi-Scale Ensemble Deep Architecture

چکیده

Accurate noninvasive diagnosis of retinal disorders is required for appropriate treatment or precision medicine. This work proposes a multi-stage classification network built on multi-scale (pyramidal) feature ensemble architecture image using optical coherence tomography (OCT) images. First, scale-adaptive neural developed to produce inputs extraction and learning. The larger input sizes yield more global information, while the smaller focus local details. Then, feature-rich pyramidal designed extract features as DenseNet backbone. advantage hierarchical structure that it allows system multi-scale, information-rich accurate disorders. Evaluation two public OCT datasets containing normal abnormal retinas (e.g., diabetic macular edema (DME), choroidal neovascularization (CNV), age-related degeneration (AMD), Drusen) comparison against recent networks demonstrates advantages proposed architecture’s ability with average accuracy 97.78%, 96.83%, 94.26% first (binary) stage, second (three-class) all-at-once (four-class) classification, respectively, cross-validation experiments dataset. In dataset, our showed an overall accuracy, sensitivity, specificity 99.69%, 99.71%, 99.87%, respectively. Overall, tangible enhanced learning might be used in various medical tasks where scale-invariant are crucial precise diagnosis.

Skin Lesion Classification Using Deep Multi-scale Convolutional Neural Networks

Melanoma is a malignant tumour originating from melanocytes cells skin cells responsible for the production of melanin. The American Cancer Society estimates that in the United States alone for 2017, more than 87,000 new melanoma cases will be diagnosed and around 9,300 persons are expected to die[1]. Skin melanoma lesions are very challenging to visually diagnose due to their similarity in vis...

Identification of Houseplants Using Neuro-vision Based Multi-stage Classification System

In this paper, we present a machine vision system that was developed on the basis of neural networks to identify twelve houseplants. Image processing system was used to extract 41 features of color, texture and shape from the images taken from front and back of the leaves. The features were fed into the neural network system as the recognition criteria and inputs. Multilayer perceptron (MLP) ne...

Bodypart Recognition Using Multi-stage Deep Learning

Automatic medical image analysis systems often start from identifying the human body part contained in the image; Specifically, given a transversal slice, it is important to know which body part it comes from, namely "slice-based bodypart recognition". This problem has its unique characteristic--the body part of a slice is usually identified by local discriminative regions instead of global ima...

Development of an Ensemble Multi-stage Machine for Prediction of Breast Cancer Survivability

Prediction of cancer survivability using machine learning techniques has become a popular approach in recent years. ‎In this regard, an important issue is that preparation of some features may need conducting difficult and costly experiments while these features have less significant impacts on the final decision and can be ignored from the feature set‎. ‎Therefore‎, ‎developing a machine for p...

Twitter Demographic Classification Using Deep Multi-modal Multi-task Learning

Twitter should be an ideal place to get a fresh read on how different issues are playing with the public, one that’s potentially more reflective of democracy in this new media age than traditional polls. Pollsters typically ask people a fixed set of questions, while in social media people use their own voices to speak about whatever is on their minds. However, the demographic distribution of us...
