Professor Paul Goldsmith-Pinkham uses machine learning to study the impact of changing credit models on cross-group disparities in the mortgage market.
Professor Bryan Kelly uses machine learning methods to study financial markets and macroeconomic fluctuations. As part of this research, he develops advanced tools for modeling the information content of textual data and its association with markets and the economy.
Professor Balazs Kovacs uses machine learning and AI methods to study the effect of category-spanning and atypicality. He used deep learning to analyze the text of patents and menus of restaurants and found that patents will receive lower citations if they are assigned to a category to which they are atypical and restaurants receive lower online ratings if their menus are atypical to the cuisine(s) the restaurant claims (e.g., French restaurant selling pizza).
Professor Vineet Kumar uses machine learning to study economic and social value drivers using unstructured data.
Professor Song Ma uses machine learning methods to study the link between human interactions and economic decision-making by analyzing ultra-high dimensional video data. He also studies the evolution of scientific discoveries and technological innovation by analyzing large set of textual information.
Professor Vahideh Manshadi's research partly focuses on the design and operation of online shopping platforms. She uses machine learning methods to study various challenges that such platforms face. For example, click farms—which employ fake consumers to click on certain products in order to trick the platform to overestimate the popularity of those products and thus rank them higher—hurt the consumer’s welfare as well as the platform's profit. In collaboration with researchers from MIT, Harvard, and Google, she aims to find solutions for product ranking on online platforms that are robust to such fraudulent clicks.
Professor K. Sudhir uses and develops machine learning and AI methods for using text and images as new data sources to investigate customer sentiment and emotion based persuasion. He has used online text reviews to study customer sentiment and image and text data in project descriptions on crowdfunding sites to study their persuasive effectiveness.
Professor Kosuke Uetake uses machine learning methods to study the effectiveness of pricing strategies in online credit markets and personalization of goals for members of a weight management application.
Professor Tauhid Zaman uses machine learning methods to study how to shift opinions in social networks. He has built multiple deep neural networks which measure the opinion of content generated in social networks with respect to several polarizing political topics in U.S., UK, and France. He is also using deep reinforcement learning to develop automated social media agents which learn how to interact with users in a social network in order to shift their opinions in a certain direction. These agents learn policies for who to target, what to say, and when to say it.
