OLIVES Research


Welcome to OLIVES, the Omni Lab for Intelligent Visual Engineering and Sciences! At OLIVES, we conduct transformational research in Machine Learning with the motto of ameliorating the data-centric nature of learning systems to be human-centric. Our research is applied to image and video processing and understanding, seismic imaging, perception in visual data processing, healthcare intelligence, and video analytics. The primary applications of the research span autonomous vehicle perception, ophthalmology, seismic interpretation, and trustworthy neural networks.

Trust in AI

Humans in the Loop

Despite the remarkable performance of AI models in various fields, the viability of these models in consumer-facing applications remains a concern. Knowing when a model’s prediction can be trusted is critical for deployment. At OLIVES, we tackle trust in AI through a three-pronged approach.

•First, we directly garner trust by enhancing the interpretability of decision making.•Next, we employ indirect applications of robustness and generalizability to enhance the applicability of neural nets in multifarious scenarios.

•Finally, we target difficult real-world settings, including seismic and biomedical interpretations, that face application-specific challenges.

  • A central factor in trustworthy autonomous systems is the presence of humans in different stages of an AI system’s deployment cycle – from data curation, to model training, evaluation, and deployment. In real world applications, an AI system requires different experts in each of these stages. For instance, in medical applications, doctors evaluate the decisions made by AI systems but are not well versed with its training. ML engineers can select the best possible models but may not be able to curate unbiased data for these models. Existing human-in-the-loop systems do not account for this variety in the required expertise. At OLIVES, we leverage limited experts and move towards experts-in-the-loop framework
