Robin Kothari, Senior Researcher, Microsoft Quantum
Wednesday, November 25, 3:00 PM (Pacific Time)
Gradient descent is a popular algorithm in machine learning and optimization and finds many applications in theory and in practice. Robin Kothari asks, “Can quantum computers speed up this algorithm?” During this seminar, Kothari will discuss the meaning of the question, formalize the question in the context of first-order convex optimization and looks at prior work in this setting. Finally, he will answer the question posed in this context.
Robin Kothari is a Senior Researcher at Microsoft Quantum. His primary area of research is quantum algorithms and complexity theory. Broadly, he studies the following question: What problems can and cannot be solved faster on an ideal (i.e., scalable fault-tolerant) quantum computer? Quantum computers only solve some problems faster than traditional computers, and it is important to identify these problems. Conversely, it is important to understand where quantum computers offer no advantage, both to avoid wasting time looking for quantum advantage for these problems and to understand the fundamental limitations of quantum computers.
This talk is based on joint work with Ankit Garg, Praneeth Netrapalli, and a preprint of this work can be found on the arXiv.
