~lagrev-nocfep and ~mopfel-winrux have been hard at work implementing numerical computing on Urbit. The end goal that they are driving towards is Urbit-native machine learning. They seek a qualified grantee to assist with this project.
Currently, they have completed significant work on the following:
- lib/math↗ enables mathematical functions for single atoms, from 
add,sub,mul, up to more complex functions such asexp,sin,cos,log, and so on. - Lagoon↗ (Linear AlGebra in hOON) enables matrix mathematics in the vein of BLAS or LAPACK (like NumPy's pure matrix operations).
 - Saloon↗ (Scientific ALgorithms in hOON) enables complex mathematical functions over matrices.
 - Maroon↗ (MAchine LeaRning in hOON) implements machine learning algorithms as a sidecar to Urbit. Primarily, this is an interpretation of the Tinygrad framework.
 
However, much work remains to be done. Areas of work include:
- Implementing a complex number type and associated algorithms.
 - Implementing a rational number type and associated algorithms.
 - Implement a stack based on posit numbers (an alternative to floating point) for Lagoon/Saloon.
 - Finish implementing fixed-precision numbers.
 - Write deterministic jets for Saloon (in C)
 - Implement APL or other numerics languages on top of Lagoon/Saloon.
 - Completing various needed tasks in the above 4 libraries.
 
There are many opportunities here and high rewards for the motivated and capable grantee. Help us make Urbit-native machine learning a reality. Reach out to us at grants@urbit.org↗ if you're curious.
