Decision tree ensembles are widely used in critical domains, making robustness and sensitivity analysis essential to their trustworthiness. We study the feature sensitivity problem, which asks whether an ensemble is sensitive to a specified subset of features -- such as protected attributes -- whose manipulation can alter model predictions. Existing approaches often yield examples of sensitivity that lie far from the training distribution, limiting their interpretability and practical value. We propose a data-aware sensitivity framework that constrains the sensitive examples to remain close to the dataset, thereby producing realistic and interpretable evidence of model weaknesses. To this end, we develop novel techniques for data-aware search using a combination of mixed-integer linear programming (MILP) and satisfiability modulo theories (SMT) encodings. Our contributions are fourfold. First, we strengthen the NP-hardness result for sensitivity verification, showing it holds even for trees of depth 1. Second, we develop MILP-optimizations that significantly speed up sensitivity verification for single ensembles and for the first time can also handle multiclass tree ensembles. Third, we introduce a data-aware framework generating realistic examples close to the training distribution. Finally, we conduct an extensive experimental evaluation on large tree ensembles, demonstrating scalability to ensembles with up to 800 trees of depth 8, achieving substantial improvements over the state of the art. This framework provides a practical foundation for analyzing the reliability and fairness of tree-based models in high-stakes applications.

Who cares about kids when adult collectors are willing to pay top dollar? From the moment a pixelated Gengar and Nidorino faced off in the opening animation of the first games on the original Game Boy back in 1996, the franchise has been a perennial favorite of kids and adults alike. With 2026 marking 30th anniversary, Lego's first-ever collaboration with the enduringly popular monster-catching megahit is perfectly timed--a crossover of pop culture titans with just one problem: Anyone who isn't an ultra-fan with cavernously deep pockets isn't invited. The recent announcement of a line of Lego Pokémon wasn't a surprise--the Danish brick brand first revealed it had entered into a "multi-year partnership" with The Pokémon Company back in March 2025 --but the makeup of the range itself was. Despite the mass appeal, Lego is launching with just three sets, and every single one is age-rated 18+.

Lego's Smart Brick Gives the Iconic Analog Toy a New Digital Brain The new sensor-packed Smart Play Brick will land this spring as part of a special Star Wars collection. The update adds interactive lights and sound to the Lego experience--including the minifigs. At CES in Las Vegas today, Lego has unveiled its new Smart Play platform, aimed at taking its distinctly analog plastic blocks and figures into a new world of tech-powered interactive play--but crucially one without any reliance on screens. Smart Play revolves around Lego's patented sensor-and tech-packed brick. It's the same size as a standard 2 x 4 Lego brick, but it is capable of connecting to compatible Smart Minifigures and Smart Tags and interacting with them in real time.

Consider two sets of entities and their members' mutual affinity values, say drug-target affinities (DTA). Drugs and targets are said to interact in their effects on DTAs if drug's effect on it depends on the target. Presence of interaction implies that assigning a drug to a target and another drug to another target does not provide the same aggregate DTA as the reversed assignment would provide. Accordingly, correctly capturing interactions enables better decision-making, for example, in allocation of limited numbers of drug doses to their best matching targets. Learning to predict DTAs is popularly done from either solely from known DTAs or together with side information on the entities, such as chemical structures of drugs and targets. In this paper, we introduce interaction directions' prediction performance estimator we call interaction concordance index (IC-index), for both fixed predictors and machine learning algorithms aimed for inferring them. IC-index complements the popularly used DTA prediction performance estimators by evaluating the ratio of correctly predicted directions of interaction effects in data. First, we show the invariance of IC-index on predictors unable to capture interactions. Secondly, we show that learning algorithm's permutation equivariance regarding drug and target identities implies its inability to capture interactions when either drug, target or both are unseen during training. In practical applications, this equivariance is remedied via incorporation of appropriate side information on drugs and targets. We make a comprehensive empirical evaluation over several biomedical interaction data sets with various state-of-the-art machine learning algorithms. The experiments demonstrate how different types of affinity strength prediction methods perform in terms of IC-index complementing existing prediction performance estimators.

However, this is not the case for multilingual text embeddings due to a lack of available benchmarks.
