Comparing Models of Medical Image Classification with Segmentation

REU student: Anika Arifin

Project description: Image segmentation provides a vital method for image analysis in various fields and applications, and different models have been designed over time to optimize this process. General testing measures along with specific image segmentation statistic tests are applied to different architectures and classifiers to gauge similarities and differences. In this poster, we compare models of image segmentation (UNet and FCN) and classifiers (SVM and Naïve Bayes’) to measure the statistical significance of each model. The goal is to analyze the resulting statistical data to find which model provides the best application of image segmentation in the medical field. Finding this result will help improve the accuracy of medical diagnosis through image segmentation.

Parallel Glowworm Swarm Optimization Classification Algorithm Implemented with Apache Spark

REU student: Bren Hutchinson

Project description: With the ever-growing relevance of big data due to the growth of the internet and technology, there is large demand for large-scale data management and classification. In this paper, we proposed an implementation of the glowworm swarm optimization classification algorithm (SCGSO) that is parallelized using the Apache Spark framework. The main idea of SCGSO is to use the capabilities of the standardized GSO algorithm in finding multi-modal solutions and apply it to to severaltarget centroid labels, and assigning any unlabeled data points to the nearest centroid. For the experimentation, four datasets were used to evaluate the SCGSO algorithm with varying dimensionality and number of data points. The experimental results show that the algorithm performs better for lower dimensionality data sets, and scales nicely with size of dataset.

Exploring Generative Adversarial Networks for Diabetic Foot Ulcer Image Segmentation

REU student: David Roth

Project description: The early and accurate diagnosis of diabetic foot ulcers (DFUs) is crucial for effective patient care. However, the conventional approach of visual inspection and manual measurements by medical experts can be subject to human error, leading to limited precision in ulcer assessment. To overcome these limitations and enhance the diagnostic process, this research focuses on leveraging advanced image segmentation techniques. While certain convolutional neural network architectures, such as U-Net and SegNet, have been applied for image segmentation, this paper delves into exploring the untapped potential of Generative Adversarial Networks (GANs) in this domain. GANs have shown remarkable success in various computer vision tasks, including image generation and image-to-image translation. We aim to investigate the effectiveness of GAN-based image segmentation methods, particularly Pix2Pix and SegAN, in accurately identifying and segmenting DFU medical images. To accomplish this, we propose the use of performance measures such as the Dice Coefficient and the Jaccard Index, among others. By identifying the most effective GAN-based approach for DFU segmentation, this research seeks to contribute to the development of more reliable and automated diagnostic tools, leading to improved patient outcomes and reduced workload for healthcare professionals.

Firefly Spark Classification Optimization

REU student: Jacob Olinger

Project description: Classification is a problem at the forefront of computer science. However, models for classification remain extremely computationally expensive. Therefore, stochastic  algorithms provide a more efficient manner of model training. Furthermore, the Apache Spark context provides parallel processing capabilities in order to further improve classifier efficiency through increasing concurrency.

Using Chemiresistive Nanomaterials to Develop a Rapid Diabetes Sensor and Derive a Resistance-Acetone Relationship

REU student: Jonah Sachs

Project description: Specific nanomaterials have been shown to possess a functionalizable resistance when placed in contact with acetone, which is severely overrepresented in the breath product of patients with medical diabetes. The sensor created will take a form similar to that of an alcohol-based breathalyzer commonly used by Police for detecting DUIs. It will utilize the chemiresistive property of a unique nanomaterial mixture, tracking resistance changes based upon the presence of acetone. Different Regression Models will be utilized to attempt to quantify Acetone levels (ppm) when given a resistance-based time series, and also in exposure to other extraneous variables. In addition, Fourier analysis and other physical techniques will be utilized. The end goal is the creation of either a threshold or model which can accurately quantify acetone based on resistance over time.

Cell Culture Image Classification Using Deep Learning

REU student: Talia Gafrick

Project description: The emergence of deep learning has highlighted the cruciality of transfer learning in numerous fields, particularly in medical imaging. However, the availability of this data is scarce due to quality standards, patient privacy, monetary incentive,etc. Transfer learning has provided a solution to this challenge. This process modifies a pre-trained image neural network architecture by fine-tuning output layers with the smaller target dataset. This poster focuses on the examination of transfer learning with breast and prostate cancer cell culture imaging. The performance of three established deep neural networks- ResNet50, VGG19, and InceptionV3- on a target dataset with various fine-tuning configurations is evaluated.
