NBBO is the composite best bid/ask nationally, across all of the exchanges.

It allows the average person on the street to get a price for the asset. The government system is actually SLOWER from the fastest exchange: you can know, within microseconds, the difference.

nearest neighbor method

Last edited: August 8, 2025

A very simple machine learning method.

For some input \(\qty (\hat{x}, \hat{y})\), find the closest training data point \(\qty (x_{i}, y_{i})\) and return its associated \(z_{i}\), with error \(\mid z_{i} - \hat{z}\mid\). Consider a Voronoi Diagram!

This surface is piecewise constant.

Framework for subsurface exploration: a DARPA challenge that explores unknown underground environments.

Main Problem: there is a high degree of uncertainty that comes from multiple different systems interacting:

  • sensing
  • environment
  • command execution
  • communication
  • mission state
  • health of systems and subsystems

NeBula treats uncertainty between systems via a POMDP:

NeBula autonomy framework extrapolation on an active source seeking. For instance, combining with semantic understanding, we want to “find the red backpack”.

needfinding as a process of finding need.

needfinding with Rick Wallace. You don’t find out what they need, but you find what they need and how to fix it. (duh?)

needfinding with Cynthia Lee

“Any time your curse, write down what just went wrong. How to fix it is the path to your next startup idea.”
