Talk Zero: Ethical, Responsible, and Safe Requirements for AI
Abstract: In a world increasingly shaped by AI technologies, including influential models like GPT-4, LLaMA, Stable Diffusion, and DALL.E, common applications of AI in natural language understanding, image generation, and more are prominent. There is an increased use of AI models in various applications, from enhancing customer service interactions to enabling creative image generation and autonomous vehicles. One can now use specialized GPTs for a variety of use cases through a AppStore-like AI marketplace, straight out-of-the-box. However, with great power comes great responsibility, and it’s imperative to acknowledge the technical, ethical, responsible, and fairness issues that accompany these powerful systems. Zooming out to the bigger picture, the talk will address the criticality of identifying ethical, responsible, and safe requirements for AI systems. Will cover some super exciting ongoing research projects at Precog Lab – methods to improve interpretability [ICML 2024], consistency [LREC-COLING 2024], Continual learning [NeurIPS 2024], detecting AI generated Hindi text [EMNLP 2024] and the removal of harmful labels and knowledge from these models [ICML 2024].

Talk one: Data Science for Social Good
Abstract: With increase in sage of the Internet, social media platforms, huge amount of data is getting generated at various level; one of the dire need of the hour is to see how we can use this data to have societal impact. I will briefly mention some super cool projects that we have worked on and that have made some visible contributions to the world outside academia. All work presented in the talk (including datasets, code, slides, recorded videos) has related publications at https://precog.iiit.ac.in/ Projects that I will touch upon are — Selfie deaths / KillFie http://labs.precog.iiitd.edu.in/killfie/ #GeneralElections2019 http://bit.ly/elections19(Mis)Information / Fake content on Twitter, Facebook, and WhatsApp, and Computing for Medicine. We all understand, many real world problems cannot be addressed by a single domain faculty / researcher, we need more students & faculty to come together, hoping to generate some interest to join hands to have an impact and make a difference. Many of our research work is made available for public use through tools or online services at https://precog.iiit.ac.in/ including datasets that we have used in our research work. Our work derives techniques from Computational Social Science, Data Science, Statistics, and Network Science. I will be more than happy to clarify, discuss, any of our work in detail, as required, after the talk.

Talk two: “Privacy and Security in Online Social Media (PSOSM)”
Abstract: With increase in usage of the Internet, there has been an exponential increase in the use of online social media on the Internet. Websites like Facebook, Instagram, Twitter, Tinder, YouTube, and many others have changed the way the Internet is being used. There is a dire need to investigate, measure, and understand privacy and security on online social media from various perspectives (computational, cultural, psychological). Real world scalable systems need to be built to detect and defend security and privacy issues on online social media. I will describe briefly some cool projects that we work on: (Mis)Information / Fake content on Twitter, Facebook, and WhatsApp; Linking profiles across different social networks; Selfie deaths and KillFies; and Manipulated followers. Many of our research work is made available for public use through tools or online services at precog.iiit.ac.in including datasets that we have used in our research work. Our work derives techniques from Computational Social Science, Data Science, Statistics, and Network Science. I will be more than happy to clarify, discuss, any of our work in detail, as required, after the talk.

Talk three: Social Computing for Medicine
Abstract: With increase in importance of computing in healthcare, there has been an exponential increase in use of computing methodologies to develop better understanding of health care systems. In the history of human lives, Health and Medicine have never seen the importance as it has in the current scenario. Perhaps for the first time in the history of democratic India, healthcare is predicted to play an important role in future election manifestos as well. I will briefly describe some cool projects that we are currently working on - WASHKaro http://precog.iiitd.edu.in/research/c4m to provide right information at the right time during pandemic situations like #COVID19; use social media as a source to study mental health & early understanding of psychological patterns of users http://covibes.tavlab.iiitd.edu.in/; build transparent Agent Based Models, classical compartmental models to allow interactions with the assumptions like lockdown, testing, & social interventions. covision http://covision.tavlab.iiitd.edu.in/ a system that we build to showcase these models. The talk will end with showcasing some grand challenges that I see in this space which can be a great starting point for students interested in pursuing research and solving some real world problems. Many of our research work is made available for public use through tools or online services at precog.iiit.ac.in including datasets that we use for research. Our work derives techniques from Social Computing, Computational Social Science, Machine Learning, Statistics, and Network Science. I will be more than happy to clarify, discuss, any of our work in detail, as required, after the talk.
