Phlotonics – Big-Data Approaches to Wafer-Scale Analysis of Silicon Biosensor Yield and Prediction of Function

PI Researcher: Ben Miller

Digital health and healthcare analytics are rapidly growing fields in data science that are paving the way to personalized medicine. Democratization of healthcare analytics will be driven by the development of new point-of-care (POC) diagnostic tools that integrate seamlessly with electronic health record systems to facilitate data aggregation for analysis with machine learning methods thus improving patient outcomes. Critical to the availability and low-cost of diagnostic tools is the scale-up of manufacturing from hundreds to hundreds of thousands and beyond. However, fabrication at this scale requires fabrication quality and yield methods that scale as well. The aims of this proposal will advance the scale-up of POC diagnostic fabrication by 1) implementing new methods for data scrubbing as well as identifying opportunities to improve the quality of raw data, and 2) mapping the relationship between inline wafer-scale refractive index data and localized sensor performance. The proposed work will stimulate economic growth in Upstate New York by promoting technology transfer from the University of Rochester to Phlotonics, a U of R spin-out company.

Kitware – Towards Robust and Fair AI Algorithms against Multiple Shortcuts

PI Researcher: Chenliang Xu

Machine learning often achieves good average performance by exploiting unintended cues in the data. For instance, when backgrounds are spuriously correlated with objects, image classifiers learn background as a rule for object recognition. This phenomenon—called “shortcut learning”—undermines the robustness and fairness of AI algorithms. The objective of this proposal is to build robust and fair AI algorithms against multiple shortcuts. In contrast to prior arts holding the single-shortcut assumption, we propose a new framework to identify and mitigate multiple shortcuts. Our work can broadly benefit many research fields, e.g., algorithmic fairness and robustness, data-centric AI, and representation learning.

Kitware – Domain Adaptation using Vision Transformers

Andreas Savakis Headshot PI Researcher: Andreas Savakis

Domain Adaptation using Vision Transformers: Domain adaptation aims to overcome the distribution shift between the target domain used for testing and the source domain used for training. We propose to utilize Vision Transformers as an alternative to convolutional features for fine-grained domain adaptation. Vision transformers, inspired by natural language processing, offer excellent performance due to their attention mechanism, and are promising for fine-grained classification. We propose to incorporate vision transformers in the source hypothesis transfer framework and apply our fine-grained adaptation method on the rare planes dataset, which includes synthetic data for training and measured data for testing.

ADVIS – Development of a Low-Cost, Low-Power Integrated Machine Health Monitoring Sensor

PI Researcher: Michael Heilemann

Development of a Low-Cost, Low-Power Integrated Machine Health Monitoring Sensor: We seek to develop a device to cost-effectively bring machine health monitoring (MHM) to a broad spectrum of DoD assets (vehicles, pumps, rotating machinery), where the implementation of conventional monitoring systems is cost prohibitive. The design objective is to provide a low-cost, general-purpose hardware platform to support a range of vibro-acoustic MHM and condition-based maintenance applications. The proposed platform will implement a novelty detection autoencoding neural network, but also will support other user-defined machine learning architectures and algorithms consistent with available memory. Availability of this inexpensive and flexible platform enables a wider adoption of MHM for both DoD and commercial applications.

Kitware – Identify Hidden Biases of AI Algorithms via Human-Machine Collaboration

AI algorithms, especially deep learning, learn biases from data; thus, it is urgent and vital to identify and mitigate biases in these algorithms. However, previous bias identification pipelines rely on human experts to conjecture potential biases (e.g., gender, color, etc.). This approach might work for limited domains and problems but have no chance to scale when considering general AI deployment; humans alone cannot realize all the biased attributes, e.g., identifying biases for a bridge classifier trained on ImageNet. Kitware, Inc. has contacted Chenliang Xu, Associate Professor in the Department of Computer Science and Wilmot Distingshied Professor 2021-2023 at the University of Rochester, to develop novel, scalable human-machine collaborative systems to assist humans in discovering hidden biases in any image classifiers.

IBM – Learning to Localize Sources of Network Diffusion

PI Researcher: Gonzalo Mateos Buckstein

Learning to Localize Sources of Network Diffusion: We propose a deep learning solution to the inverse problem of localizing sources of network diffusion. Invoking graph signal processing (GSP) fundamentals, the problem boils down to blind estimation of a diffusion filter and its sparse input signal encoding thesource locations. While the observations are bilinear functions of the unknowns, a mild requirement on invertibility of the filter enables a convex reformulation that we solve via the alternating-direction method of multipliers (ADMM). We unroll and truncate the novel ADMM iterations, to arrive at a parameterized neural network architecture for Source Localization on Graphs (SLoG-Net), that we train in an end-to-end fashion using labeled data. This way we leverage inductive biases of a GSP model-based solution in a data-driven trainable parametric architecture, which is interpretable, parameter efficient, and offers controllable complexity during inference. By advancing innovative machine learning technologies to tackle data science problems encountered with sensor, information, social, and brain networks, this university-industry collaboration is primed to generate economic and broader societal impacts.

Flaum Eye Institute – 3D eye imaging and machine learning strategies to improve cataract surgery

Cataract surgery is the most often performed surgery in any hospital of the world (28 million/year). However, the process by which the intraocular lens to replace crystalline lens is selected relies on limited anatomical information and rudimentary formulas. Susana Marcos worked with the Flaum Eye Institute at the University of Rochester will attempt to propose the use of 3-D quantitative optical coherence tomography images and machine learning approaches to obtain an accurate expression of the estimated lens position based on the pre-operative anterior segment anatomy and full crystalline lens shape. This method will improve the refractive outcomes of cataract surgery, increasing patient satisfaction and reducing the burden of refractive error correction.
