## Planning under Uncertainty ## Planning under Uncertainty
During my PhD I have been primarily focused on investigating planning and sequential decision During my PhD I have been primarily focused on investigating planning and sequential decision
making under uncertainty through integrative methods: making under uncertainty:
- With [Selmer Bringsjord](https://homepages.rpi.edu/~brings/) in the [RAIR Lab](https://rair.cogsci.rpi.edu/) I have looked at planning through automated reasoning. - I created a new framework which allows agents to make plans under *qualitative uncertainty*.
This helps in settings where the user doesn't have exact probabilities that various
facts holds, but can instead bucket them into different likelihood values.
This work is supervised under [Selmer Bringsjord](https://homepages.rpi.edu/~brings/).
- Additionally with Selmer Bringsjord in the [RAIR Lab](https://rair.cogsci.rpi.edu/), I have looked at planning through automated reasoning.
I further developed [Spectra](https://github.com/rairlab/spectra) and the underlying I further developed [Spectra](https://github.com/rairlab/spectra) and the underlying

can be encoded for characterizing discovery of unknown predicates. This techinque can be encoded for characterizing discovery of unknown predicates.
uses a fully-observable non-deterministic planner to generate a high-level policy
where each high-level action is an option that a reinforcement learning agent
needs to learn.
