In each epoch of an RDS study\ , the current wave of study participants are incentivized to recruit the n ext wave through their social connections. The success and efficiency of R DS can depend critically on attributes of incentives and the underlying (l atent) network structure. We propose a reinforcement learning-based adapti ve RDS design to optimize some measure of study utility\, e.g.\, efficienc y\, treatment dissemination\, reach\, etc. Our design is based on a branch ing process approximation to the RDS process\, however\, our proposed post -study inferential procedures apply to general network models even when th e network is not fully identified. Simulation experiments show that the pr oposed design provides substantial gains in efficiency over static and two -step RDS procedures.\n\nSpeaker bio\n\nPlease visit: https://laber-labs.c om\n\n \n DTSTART:20240327T193000Z DTEND:20240327T203000Z SUMMARY:Reinforcement Learning for Respondent-Driven Sampling URL:/epi-biostat-occh/channels/event/reinforcement-lea rning-respondent-driven-sampling-356192 END:VEVENT END:VCALENDAR
