Talk 1 - 10:00am-11:00am

Andy Sun

Title
Electric Power System Operations and Planning in Transition to a Net-Zero Emissions System
Abstract

To combat global warming, the electric power system must go through a rapid and complete decarbonization to reach a net-zero emissions system by mid-century. In this talk, we will present recent research progress on the decarbonization of electric energy systems and discuss their impacts on industry practices. We will also share his vision in creating a more collaborative future for electric energy systems. In particular, we will present new decision-making frameworks for overcoming three key challenges in the future power grids: 1) deep renewable penetration, 2) distributed generation, and 3) the increasing risk of grid infrastructure failure. Then, we will discuss the implementations of these new decision tools in the power industry. Finally, we will briefly discuss some on-going research in multi-energy systems, such as gas-electricity coordination and electric transportation.

Title
Computer Vision for Global-Scale Biodiversity Monitoring
Abstract

Biodiversity is declining globally at unprecedented rates. We need to monitor species in real time and in greater detail to quickly understand which conservation efforts are most effective and take corrective action. Current ecological monitoring systems generate data far faster than researchers can analyze it, making scaling up impossible without automated data processing. However, ecological data collected in the field presents a number of challenges that current methods, like deep learning, are not designed to tackle. Biodiversity data is correlated in time and space, resulting in overfitting and poor generalization to new sensor deployments. Environmental monitoring sensors have limited intelligence, resulting in objects of interest that are often too close/far, blurry, or in clutter. Further, the distribution of species is long-tailed, which results in highly-imbalanced datasets. These challenges are not unique to the natural world, advances in any one of these areas will have far-reaching impact across domains. To address these challenges, we take inspiration from domain experts, and seek to incorporate structure from ecological domains into computer vision systems. Incorporating species distributions and temporal signal at inference time can improve generalization to new sensors, and deploying these models in accessible human-AI systems enables us to speed up and scale up ecological data processing while maintaining high accuracy.

Sara Beery is a final-year PhD Candidate in Computing and Mathematical Sciences at Caltech, advised by Pietro Perona. She has always loved the natural world and has seen a growing need for technology-based approaches to conservation and sustainability challenges. Her research focuses on building computer vision methods that enable efficient, accessible, and equitable global-scale biodiversity monitoring. She was honored to be awarded both the PIMCO Data Science Fellowship and the Amazon AI4Science Fellowship, which recognize senior graduate students that have had a remarkable impact in machine learning and data science, and in their application to fields beyond computer science. Her work is funded in part by an NSF Graduate Research Fellowship and the Caltech Resnick Sustainability Institute. She seeks to break down knowledge barriers between fields: she founded the successful AI for Conservation slack community (with over 650 members), and she is the founding director of the Caltech Summer School on Computer Vision Methods for Ecology. She works closely with Microsoft AI for Earth, Google Research, and Wildlife Insights where she helps turn her research into usable tools for the ecological community. Sara's experiences as a professional ballerina, a nontraditional student, and a queer woman have taught her the value of unique and diverse perspectives, both inside and outside of the research community. She is passionate about increasing diversity and inclusion in STEM through mentorship, teaching, and outreach.

Title
Improving Farmers’ Welfare via Digital Agricultural Platforms
Abstract

In order to improve the welfare of smallholder farmers, multiple countries (e.g., Ethiopia and India) have launched digital agricultural platforms to transform traditional markets. However, there is still mixed evidence regarding the impact of these platforms and more generally how they can be leveraged to enable more efficient agricultural supply chains and markets. In this talk, we describe a body of work that provides the first rigorous impact analysis of such a platform and highlights several important supply chain and logistics parameters that can inform its design and optimization. The work is focused on the Unified Market Platform (UMP) that connects all the agriculture markets in the state of Karnataka, India. Leveraging both public data and detailed bidding data from the platform, a difference-in-differences analysis demonstrates that the launch of the UMP has significantly increased the modal prices of certain commodities (2.6%-6.5%), while prices for other commodities have not changed. Furthermore, the analysis provides evidence that logistical challenges, bidding efficiency, market concentration, and price discovery processes are important factors explaining the variable impact of UMP on prices. These insights led to the design and field implementation of a new two-stage auction mechanism. The auction design aims to intensify anticipated regret of the traders to increase the farmers' revenue. To ensure implementability and protect farmers' revenue, the design process is guided by theory-informed, semi-structured interviews with a majority of the traders in the field and carefully accounts for operational constraints. The interviews suggest that both anticipated regret and anchoring would likely affect the traders' bidding strategies in a two-stage auction. A new behavioral auction model is thus developed to capture these factors and determine when the two-stage auction can generate a higher revenue for farmers than the traditional single-stage, first-price, sealed-bid auction. The new auction mechanism was implemented on the UMP for a major market of lentils in February 2019. By March 2020, commodities worth more than $19 million (USD) had been traded under the new auction. A difference-in-differences analysis demonstrates that the implementation has yielded a significant 3.6% price increase with an impact on farmer profitability ranging 55%--94%, affecting over 20,000 farmers who traded in the treatment market. This talk is based on joint work with Retsef Levi (MIT), Somya Singhvi (USC), Manoj Rajan (ReMS) and his team in Karnataka, India.
