We applied intrinsically motivated #AI to explore a chemical system in the lab: https://advances.sciencemag.org/content/6/5/eaay4237 … @ScienceAdvances
Results:
- 3x more varied observations than screening
- enabled new observation that we study in depth
- data show we improve rate of discoveries

The intrinsically motivated #AI algorithm generated more varied observations. (Left)
It made salient an underlying temperature effect that could not have been observed with a parameter screening procedure. (Right) 3/8pic.twitter.com/kRdoze7QVD

We obtained such results by using the simplest form of intrinsically motivated
#AI, random goal exploration. It works better at exploring a new system because it focuses on the observations rather than on the parameters. It does not need prior knowledge to get started. 4/8Prikaži ovu nit -
This comparative study was made directly on the droplets in the lab. NO SIMULATION. This was made possible thanks to our new high-throughput parallel robot called Dropfactory. Youtube: https://youtu.be/bY5OoRBJkf0 Github: https://github.com/croningp/dropfactory … 5/8pic.twitter.com/3NASLqEPl8

The process unveiled a sudden and highly specific response of droplets to slight temperature changes. Six modes of self-propelled droplet motion were identified and classified using a time-temperature phase diagram and probed using a variety of techniques including NMR. 6/8pic.twitter.com/zwi2AqTURw

This work took us 2 years to complete. I had the privilege to work with an amazing multidisciplinary team, able and willing to engage in constructive collaboration. Thanks to
@LauriePoints,@_sharmaabhi_ and@leecronin (and the all@CroninLab ) for making this possible! 7/8Prikaži ovu nit -

@pyoudeyer@Clement_MF_@FBenureau@CULLYAntoine@kenneth0stanley@DoctorJosh@joelbot3000 this might be of interest to you as one example of using intrinsic motivation / novelty search in a chemistry lab.Prikaži ovu nit
