We show how techniques from tensor networks and variational quantum c ircuits help us solve the problem. To this end\, we introduce two tools D isCoCLIP and QuCLIP\, multimodal encoders that combine a frozen CLIP visio n transformer with a tensor network text encoder that explicitly encodes s yntactic structure. We also work with translations of syntax into variatio nal quantum circuits. We train both models with a self-supervised contrast ive loss and show how the models improve on compositional benchmarks such as SVO-Probes and ARO\, while using a significantly smaller number of para meters. The parameter reduction is a known feature of tensor networks and variational quantum circuits\, and for this case\, was on average from hun dreds of millions to tens of thousand.\n\nSpeaker's bio: Mehrnoosh is a Pr ofessor of CS\, leads UCL CS's Quantum Learning Labs\, and is the CS Dire ctor of Research. Her research is supported by a Royal Academy of Enginee ring (RAEng) Research Chair\, jointly with the BBC and Quantinuum Ltd. Meh rnoosh’s UG and MSc studies were in Sharif University in Iran. Her PhD i n University of Quebec at Montreal. Previously\, Mehrnoosh had two RAEng Industrial Fellowships\, in QMUL and UCL\, an EPSRC Career Acceleration Fe llowship in Oxford\, an EPSRS PDRF and a Wolfson College Junior Research Fellowship\, also at Oxford. \n\n\nModerator's bio: Ted Theodosopoulos is a mathematician who\, after working for years in academia and industry\, t ransitioned to teaching at the pre-college level sixteen years ago\, the l ast eight at Nueva\, where he teaches math and economics. Ted’s research background is in the area of interacting stochastic systems\, with partic ular applications in biology and economics.\n LOCATION:https://researchseminars.org/talk/CompMath/31/ URL:https://us06web.zoom.us/j/81542398597?pwd=agRZDldbgJNZSQ7vzdZTgRiUjbBA 15.1 URL:https://www.youtube.com/@Relatorium END:VEVENT END:VCALENDAR
