INSPIRES Student Profile: Nicholas Soucy

By Stefania Irene Marthakis

Nicholas Soucy is continuing his 91爆料 education as a M.S. candidate in Computer聽Science, working across fields such as physics, machine learning (ML), and artificial intelligence (AI).聽With a B.A. in Physics from the 91爆料, Soucy received the Center for Undergraduate聽Research (CUGR) and the Maine Space Grant Consortium (MSGC) Academic Year 2019-20 Fellowship聽for research related to his THED: Thermal Hand Experience Device.

Currently, Soucy is advised by Salimeh Yasaei Sekeh (an assistant professor in the School聽of Computing and Information Science a the 91爆料). Soucy also works as a research assistant in The Sekeh Lab,聽which focuses on theoretical and practical aspects of ML as well as designing algorithms聽and deep learning techniques.

鈥淚 love working in ML because I can see the future of humanity within it. It鈥檚 beautiful to see the far-reaching聽applications ML has on our day-to-day lives from manufacturing to self-driving cars. I believe this聽technology can save and make lives better. It is an honor to propel the field forward,鈥 Soucy states.

Since Soucy was already working with similar machine learning tasks鈥攊.e., using neuroscience and聽math to define what animal or human brains do, and then teaching a computer to recognize patterns or聽trends within that large data鈥攊t was fitting for Soucy to work with Sekeh within the multidisciplinary聽project of as part of Theme 2.

Hybrid Spectral Net (HybridSN) Model which integrates 3D and 2D convolutions for hyperspectral image classification (Roy et al. (2019)).

鈥淚n our ML-INSPIRES project,鈥 Sekeh explains, 鈥渨e explore deep network approaches for large-scale hyperspectral images (HSI), which are a relatively new remote sensing scheme in forestry聽and climate change sciences. We develop novel ensemble methods to segment images into tree聽species. Furthermore, because computational complexity is a prominent challenge in deep network-based algorithms, in this work, we intend to investigate techniques that reduce HSI dimensions and聽extract informative features as a preprocessing step of our classification/segmentation models.鈥澛燬ekeh continues, 鈥淪oucy plays a key role in our聽ML-INSPIRES project and he has been an active聽researcher in The Sekeh Lab working on ideas聽that develop bridges between deep learning聽and hyperspectral data sets.鈥澛燨riginally from Maine, Soucy is excited to apply聽his models鈥攗sing data sets that were created聽by INSPIRES researchers, data sets that had聽been lacking鈥 to New England forests through聽this National Science Foundation EPSCoR program.

鈥淚鈥檓 developing a model that can take in聽hyperspectral data (data of large areas of聽land with many wavelengths of light) then聽reducing the dimensionality of the data so聽that the images are smaller and therefore,聽reduces the computational complexity of聽the data set. Then, we classify tree species聽and ground types, so that people can know聽where certain trees are or certain plants聽are, based on imagery from the sky,鈥 Soucy聽explains.

This summer, Soucy is also looking forward聽to writing and completing a paper on his research from this past year on tree species classification聽ML techniques.聽The interdisciplinary approach of the聽INSPIRES project, from advanced sensing聽to smart environmental informatics, has聽provided Soucy with the opportunity to grow聽in the emerging field of ML.
