Great work showing how intrinsically motivated goal exploration can be used to automate discovery of novel patterns in wet chemical systems !!!
Congratulations @jgrizou and team!

Given these results, and having spent time in a chemistry lab, I can see a huge potential in bringing automated discovery in the labs.
A useful direction of research is how to forge the feature space from raw observations. See arxiv.org/abs/1803.00781.

Thanks Antoine! I aimed to show how goal based exploration algorithms can assist scientists in their lab to generate new observations.
I used a simple algorithm, easy to explain across the board. The aim is to change researchers search strategies from parameters to observations.

@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.

If interested in bringing automation in your lab, we made our software and hardware tools open-source online:

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! 7/8

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. 6/8 pic.twitter.com/zwi2AqTURw

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.

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. 4/8

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) 3/8 pic.twitter.com/kRdoze7QVD

We studied oil-in-water droplets. They can exhibit a range of dynamic movement depending on their composition.

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

Emtremely excited to finally share a side-project I've been working on for the past few months: Neural Synesthesia, visualizing music with #GANs!
So many ideas left to explore, this journey is just getting started..

Ever played pong with sheeps?
Check these guys out: youtu.be/qniwI2hNhDs doing some extreme sheep herding. The fun starts at 36s.

If only some group somewhere had built an affordable & accessible DIY closed loop real-time materials discovery robot that programmes the morphology of nanoparticles using Darwinian evolution. @CroninLab chemrxiv.org/articles/A_Nan…

What journal would be best suited for our work on the exploration of chemical droplets using a curiosity driven robotic assistant: arxiv.org/abs/1904.12635 ?

Just moved my coding environment to JupyterLab. Be sure to check it out: jupyterlab.readthedocs.io. Thanks @RemyKusters for the tip.
