An Ode to Dyna
As Polo measured out his term in China
By itemizing bales his factors shipped,
Deriving all his millions, till he slipped
South to the sun, charting almost to the Line a
Fair passage through the straights; as down the mine a
Bent digger waits until the bellman's tripped
The switch and smiths the annealing steel have dipped
In sump; so have we coded until Dyna
Could outclass all our programmers' array
Of tricks and like a dynast's legions hashed
Them up. The forests we wandered now give way
To fields. The cells are open where we thrashed
About. In time our terms with terms combine a
Goal to reach, with all our thanks to Dyna.
- David A. Smith

When will DynaMITE be available?

DynaMITE (the Dyna Module for Iterative Training and Estimation) is coming in the near future. We want to make sure the interface is clean and not too hard to understand, and relatively stable. We also want to make sure that the things it relies on Dyna code for (like gradients) work properly.

Where do Dyna developers eat lunch?

See this page.
