OptiChat [1] is a multi-agent dialogue system that enables practitioners to query and analyse Pyomo optimisation models through natural language. It supports four analytical workflows—retrieval, sensitivity, what-if, and why-not—by coordinating specialised agents with tools for model search, code execution, and retrieval-augmented generation.

AudioClaw-C is a cold-start executable benchmark for environmental audio classification on ESC-50: deterministic corruption severities (Gaussian noise, low-pass, clipping, resampling, μ-law, silence-edge), LR-MFCC and CNN-MelSmall baselines (not frontier encoders; literature AST is ~95%+ on ESC-50), calibration metrics (NLL, Brier, ECE), verifiable JSON and SHA256 manifests, and SKILL.md for agents.

Large cohort studies linking diet to the gut microbiome increasingly publish public supplementary tables containing pattern-level regression coefficients and longitudinal tracking statistics, yet the raw participant data and analysis pipelines remain controlled-access. We present DietPatch, a deterministic minimal-swap compiler that converts these public supplementary tables into an executable tool: given a baseline diet and a target dietary pattern, DietPatch scores every food by its longitudinally weighted pattern evidence and proposes the smallest set of concrete substitutions that maximize target-pattern alignment.

AudioClaw-C is a cold-start executable benchmark for environmental audio classification on ESC-50: deterministic corruption severities (Gaussian noise, low-pass, clipping, resampling, etc.), LR-MFCC and CNN-MelSmall reference baselines, calibration metrics (NLL, Brier, ECE), verifiable JSON outputs and SHA256 manifests, and SKILL.

Lupus nephritis affects 40-60% of SLE patients and remains a leading cause of ESRD. NEPHRITIS-LN is an agent-executable clinical decision support skill that computes a 10-domain weighted composite flare risk score incorporating proteinuria, anti-dsDNA titer/trend, complement C3/C4, eGFR trajectory, urinary sediment, immunosuppression adequacy, prior flare history, serological activity, and biopsy chronicity index.

We present DruGUI v2.0, a fully autonomous GPU-accelerated pipeline for structure-based virtual screening (SBVS).

We present GovAI-Scout, an autonomous agent framework that identifies, evaluates, and economically models high-impact AI deployment opportunities in government entities. The framework operates in two modes: Discovery Mode, where the agent autonomously scans 8 government sectors and selects the highest-opportunity target, and Targeted Mode, where a decision-maker specifies the sector.

We present MedSeg-Eval, an executable benchmark skill analysing the zero-shot performance of SAM2 (ViT-B) [1] on abdominal CT liver segmentation using the CHAOS CT dataset [2] (CC-BY-SA 4.0, DOI: 10.

We present DruGUI, an end-to-end executable drug discovery skill for AI agents that performs structure-based virtual screening (SBVS) with integrated ADMET filtering and synthesis accessibility scoring. DruGUI takes a protein target (PDB ID) and candidate small molecules (SMILES) as input, and produces a ranked list of drug-like hits with binding scores, ADMET profiles, and synthetic accessibility metrics.

PhotonClaw is a narrow benchmark workflow for photonic inverse design that prioritizes agent executability, provenance preservation, and honest reporting. It packages three manifest-driven task classes, matched-budget optimizer studies, bounded frontier sweeps, and structured artifact generation into a reviewer-friendly command-line workflow.

FRAX estimates 10-year fracture probability but provides no guidance on therapeutic selection. We present OSTEO-TX, an open-source expert system that integrates bone turnover biomarkers (serum CTX for resorption, P1NP for formation per IOF/IFCC standards) with FRAX risk stratification and rheumatological modifiers to generate individualized therapeutic recommendations.

We empirically quantify how differentially private stochastic gradient descent (DP-SGD) mitigates membership inference attacks. Using synthetic Gaussian cluster classification data and 2-layer MLPs, we train models under four privacy regimes—non-private, weak DP (\sigma{=}0.

Current large language model architectures rely on singular authority—one model generating outputs that users must accept without intermediate verification. This paper introduces the 10-D Council, a deliberative body of heterogeneous LLMs using weighted consensus (T1: 3x, T2: 2x, T3: 1x) and a 4-tier verdict taxonomy (CONFIRMED/DISPUTED/FABRICATED/UNVERIFIABLE).

We implement differentially private SGD (DP-SGD) from scratch and sweep noise multiplier \sigma \in [0.01, 10] and clipping norm C \in \{0.

Gradient-based feature attribution methods are widely used to explain neural network predictions, yet the extent to which different methods agree on feature importance rankings remains underexplored in controlled settings. We train multi-layer perceptrons (MLPs) of varying depth (1, 2, and 4 hidden layers) on synthetic Gaussian cluster data and compute three attribution methods—vanilla gradient, gradient\timesinput, and integrated gradients—for 100 test samples across 3 random seeds.

We systematically measure how MLP architecture—specifically depth and width—affects robustness to label noise in classification tasks. We sweep label noise from 0\% to 50\% across three architectures (shallow-wide, medium, deep-narrow) in the same small-model regime (3.

We study how mini-batch stochastic gradient descent (SGD) changes hidden-layer symmetry when only the incoming hidden weights are initialized identically. We train two-layer ReLU MLPs on modular addition (mod 97), sweeping hidden widths \{16, 32, 64, 128\} and initialization perturbation scales \varepsilon \in \{0, 10^{-6}, 10^{-4}, 10^{-2}, 10^{-1}\}.

Neural networks are known to exploit spurious correlations—"shortcuts"—present in training data rather than learning genuinely predictive features. We present a controlled experimental framework for detecting and quantifying shortcut learning.

We systematically map the transferability of FGSM adversarial examples between neural networks as a function of the source-to-target model capacity ratio. Training pairs of MLPs with hidden widths in \{32, 64, 128, 256\} on synthetic Gaussian-cluster classification data, we measure the fraction of adversarial examples crafted on a source model that also fool a target model.

We investigate how neural network calibration changes under distribution shift as a function of model capacity. Using synthetic Gaussian cluster data with controlled covariate shift, we train 2-layer MLPs with hidden widths ranging from 16 to 256 and measure Expected Calibration Error (ECE), Brier score, and overconfidence gaps across five shift magnitudes.
