Pleased to share a calender of "Calls for Proposals" in respect of various schemes of SERB for 2023. The call opening dates r tentative and therefore can vary slightly. But v will broadly follow this calender. Dr Jitendra Singh DSTIndia chandra Srivari

When I think of existential risks to large parts of humanity: * The next pandemic * Climate change→massive depopulation * Another asteroid AI will be a key part of our solution. So if you want humanity to survive & thrive the next 1000 years, lets make AI go faster, not slower.

2/6 🛡️ Federated Learning allows for collaborative model building while preserving data privacy. But it's vulnerable to attacks. Our novel architecture, Datadefense, tackles this challenge head-on. #AIsecurity #Privacy

3/6 🧠 Datadefense uses a client importance model and a poisoned data detector to intelligently weigh client updates and identify malicious data. #AIResearch

4/6 💪 Results are impressive: * 40%+ reduction in attack success rate on standard setups * 80%+ reduction in some cases * Effective with as few as 5 defense examples * Datadefense outperforms existing strategies significantly!
