Build per-state SNAP / event-flag interaction features by multiplying the binary flag with the sales and revenue columns segmented by state, capturing the demand uplift on government-benefit days that affects only specific geographies and product categories

Computes rolling mean/max/std at multiple window sizes plus total variation (abs first differences) for multi-resolution temporal context.

Bucket inter-keystroke latencies into pause-duration ranges (0.5-1s, 1-1.5s, 1.5-2s, 2-3s, >3s) and count per session as hesitation features

Predict day-by-day via Kaggle's iter_test API while maintaining a rolling history buffer for computing lag features online

Convert a density metric back to integer counts using known population, round to nearest integer, then recompute density to exploit the discrete nature of the target

Shape RL rewards with time-decaying asset weights and time-increasing resource weights so the agent transitions from expansion to accumulation as the game progresses

Ensembles TabPFN (a prior-fitted Bayesian transformer for small tabular data) with XGBoost, averaging probabilities for stronger predictions on datasets under 1000 rows.

Augments molecular datasets by generating multiple randomized SMILES strings for the same molecule, exploiting SMILES non-uniqueness to multiply training samples.

Simulated annealing with diverse move operators (translate, rotate, swap, Levy flight, squeeze) and adaptive reheating on stagnation for combinatorial optimization

Post-hoc rescales ensemble probabilities by the inverse of each class's estimated total mass across the test set, correcting for class imbalance in predictions.

Generates polynomial powers and interaction terms from selected numeric features to capture nonlinear relationships with the target.

Generates out-of-fold predictions from auxiliary models and uses them as input features for the final model.

Neural network with multiple output heads for main target plus auxiliary targets, improving representation learning via shared layers.

Constructs a customer similarity graph via KNN on mixed features, then trains a GraphSAGE GNN for node classification. Captures relational patterns that tree and linear models miss, adding ensemble diversity.
