Solving Hard Engineering Problems with Deep Learning

Date/Time: September 24, 3:40 pm
Location: B29 Atanasoff Hall


Over the last few years, Deep Learning models have outperformed all other state-of-the-art machine learning techniques for many detection, classification and prediction problems. With the capability of handling very large data sets, these very large models extract hierarchical features at different scales of data without the need of hand-crafting. While at the lower layers, more primitive features are extracted, composite features (features of features) are extracted at the upper layers that are more expressive and often semantic in nature. However, most of the studied applications have been in the domains of computer vision, speech processing and natural language processing. This talk will discuss a couple of recent success stories of Deep Learning (i.e., unsupervised and supervised models, deep belief nets and deep convolutional nets) for two engineering applications that are rather nontraditional in the context of machine learning. The first one involves designing microfluidic lab-on-chip devices in real-time to achieve user-defined flow shapes that has enormous potential applications ranging from manufacturing new classes of polymerized fibers with engineered interactions to detecting human diseases. The second application is about early detection of flame instability in combustion processes via deep feature extraction from hi-speed flame images in order to prevent catastrophic lean blow out in aircraft and other engines.
