       | "Embodied" seems like a stretch. I would imagine "embodied" to
       | mean something involving feedback control using multimodal
       | sensory data. Otherwise it's no different from playing Atari Pong
       | with a larger state and action space. Moving around in a quasi-3D
       | environment, being essentially represented as a point with a
       | sprite wrapped around it, is not what distinguishes a "bodied"
       | agent from other kinds.

         | Agreed for the most part.
         | 
         | If we were to be extra generous, then the audio and visuals in
         | minecraft could be a toy case of training an agent with a
         | multimodal sensorium (can the agent avoid enemies sneaking up
         | on them using sound cues, find mobs based on sounds, know lava
         | is nearby by the bubbling etc.).
         | 
         | In this case though the agent is given just RGB pixels and some
         | structured data about their inventory, a small number of nearby
         | voxels, their health etc.
         | 
         | You'd have to be very generous to call structured data like
         | that and some RGB pixels a multi-modal embodied agent though.

       | should really do tests to see if a non-technical person can tell
       | them what their website represents in under 10 - 60 seconds, if
       | they can't you need to rework your homepage so the immediate
       | information fed to the end-user tells you what you are "selling"
       | otherwise, you'll typically get people like me who close the tab
       | and leave.

         | 
         | You're not the target audience, why should they appeal to you?
         | This is a website accompanying a paper about reinforcement
         | learning.
