When Do Discrete Actions Make Good Continuous Controllers?

Zeji Yi, Soham Dasgupta, Xinyang Zhang +5

Though modern AI models like LLMs predict discrete tokens, today's robotic foundation models represent actions as continuous vectors. In this paper, we challenge this common consen…

Wavelength Calibration Accuracy Across the STIS CCD: Pipeline Update and User Guidance

Matilde Mingozzi, Robert Jedrzejewski, Matthew Siebert +3

We investigate the wavelength calibration accuracy of STIS CCD spectra as a function of detector position, focusing on the E1/E2 pseudo-apertures. Comparison between measured lamp…
