FISH is the MIT Earth Resource Laboratory's Friday Informal Seminar Hour. Held most Fridays during the academic year in 54-209, the series features talks in our lab's areas of interest: geophysics, seismology, rock physics, imaging, inversion/inference, and machine learning.

Dr. Yunyue Elita Li, an Assistant Professor at the National U. of Singapore and Research Affiliate in the MIT Earth Resources Laboratory, presents "Waveform inversion with gradient sampling - new understanding of the spatial shifts" at ERL.

Dr. Hongfu Liu, Assistant Professor at Brandeis U., presents "From Consensus Clustering to K-means Clustering" at the MIT Earth Resources Laboratory.

ERL Special Talk: Ping Wang (CGGVeritas): Full Waveform Inversion for Subsalt Imaging 

FWI is considered the most promising data-driven tool to automatically build velocity models by iteratively minimizing the difference between recorded data and modeled synthetic data. However, its impact on subsalt imaging had been long missing until the recent emergence of reflection FWI and advancement of diving-wave FWI. We present a few FWI approaches that we observed are able to update either the salt body or subsalt velocity or both and thus improve the subsalt imaging.
