🧵 Tropical Attention --> Softmax is out, Tropical max-plus is in 🦾.1/ 🔥Ever experinced softmax attention fade as sequences grow?.That blur is why many attention mechanisms stumble on algorithmic and reasoning tasks. Well, we have a Tropical solution 🌴

R2: timely study, extremely bold and ambitious, mentioning NO weaknesses at all, only one question of future directions, then 2: reject….WTH!!!.#NeurIPS2025.

It is still surprising to me how such a deep structure, Grothendieck-Riemann-Roch theorem, arises from merely a book-keeping dictionary, aka Divisors.

6/ We also show that each Tropical attention head can function as a tropical gate in a tropical circuit, simulating any max-plus circuit.

5/ We benchmarked on 11 canonical combinatorial tasks. Tropical attention beat vanilla & adaptive softmax attention on all three OOD axes, Length, value and Adversarial attack generalization:

4/ Tropical Attention runs each head natively in max-plus. Result: .Strong OOD length generalization with sharp attention maps even in several algorithmic tasks, including the notorious Quickselect algorithm (Another settlement for the challenge identified by @michael_galkin)

3/ In the Tropical (max + ) geometry, “addition” is max, “multiplication” is +. Many algorithms already live here, carving exact polyhedral decision boundaries --> so why force them through exponential probabilities?.Let's ditch softmax, embrace the tropical semiring 🤯🍹.

If one tries to observe below the Planck time, the very act of observation using any apparatus exeeds its own Schwazschild radius and triggers gravitational collapse and a black hole.
