mlr3benchmark
A small mlr3 add-on for comparing learners, spending most releases making its statistics honest.
A side-by-side editorial comparison of Alhena AI and pomdp — release velocity, themes, recent moves, and the top alternatives to consider.
Alhena is building the scoreboard for shopping agents it also competes in.
Alhena's feed carries original benchmark research rather than release notes. The August work centres on a stress test of 15 live AI shopping agents run through real storefronts: all 15 could answer questions, 9 could sell, 4 could complete a return, and 1 recognised a returning shopper. The newest post drills into the widest of those gaps — the distance between an agent explaining a return policy and actually executing the return.
A POMDP solver that quietly grew into a full reinforcement-learning toolkit.
pomdp is an R interface to the pomdp-solve engine for partially observable Markov decision processes, now carrying its own MDP solvers, gridworld environments and simulation code. The 2024 releases moved the heavy accessor and simulation paths into C++ with sparse-matrix support. Recent activity is maintenance-grade: the latest release only adds source data and a journal citation.

The publishing arc moves from vertical guides toward measurement and public scorekeeping. Earlier posts were operator playbooks for wellness brands; the recent ones define a capability ladder — answer, sell, act, remember — and grade named competitors against it. Alhena also appears in its own comparison tables alongside Profound, Peec AI and Scrunch, so the research doubles as positioning. None of this reports a change to Alhena's product.
Expect the answer-to-act gap to become a repeated benchmark with fresh vertical cuts, since the census format has already been reused across health and wellness retail. Whether Alhena ships agent capabilities matching the ladder it publishes is not visible in this feed, which carries no release notes.
pomdp is an R interface to the pomdp-solve engine for partially observable Markov decision processes, now carrying its own MDP solvers, gridworld environments and simulation code. The 2024 releases moved the heavy accessor and simulation paths into C++ with sparse-matrix support. Recent activity is maintenance-grade: the latest release only adds source data and a journal citation.
The arc runs from POMDP file parsing toward being a general teaching and research toolkit for sequential decision problems, with Q-learning, Sarsa and expected Sarsa sitting beside the exact solvers. Each cycle has widened the MDP side while normalising the POMDP side into a single model representation. The cadence has slowed markedly since the 1.2.0 push, and the newest entry is documentation rather than code.
With the R Journal reference now landed, the near-term work is most likely consolidation — more datasets and gridworld environments rather than new solver classes.
