  • Source-Bounded Exact Recovery over Docker's Logs API

    Kelvin Amoaba

    Preprint 2026

    Abstract

    Defines source-bounded exactness — every retained, distinguishable Docker source record eventually appears exactly once in durable collector output — with a generation-aware multiset oracle that separates source truncation from collector omission. Across 120 collector-runs, a fixed LogDeck revision was exact in 60/60 trials while unmodified Grafana Alloy 1.18.0 was exact in 20/60, showing that lifecycle reacquisition, not a persisted read position alone, determines exact recovery within the retained-source horizon.

  • CoFEE: Reasoning Control for LLM-Based Feature Discovery

    Maximilian Westermann, Ben Griffin, Aaron Ontoyin Yin, Zakari Salifu, Yagiz Ihlamur, Kelvin Amoaba, Joseph Ternasky, Fuat Alican, Yigit Ihlamur

    arXiv 2026

    Abstract

    A framework for automating feature discovery from unstructured data using LLMs with cognitive constraints, inducing reasoning behaviors like backward chaining from outcomes and verification against data leakage criteria. Achieves 15.2% higher success rate, 29% fewer features generated, and 53.3% cost reduction over vanilla LLM approaches.

  • VCBench: Benchmarking LLMs in Venture Capital

    Rick Chen, Joseph Ternasky, Afriyie Samuel Kwesi, Ben Griffin, Aaron Ontoyin Yin, Zakari Salifu, Kelvin Amoaba, Xianling Mu, Fuat Alican, Yigit Ihlamur

    Computing Conference, Springer LNNS 2026

    Abstract

    The first benchmark for predicting founder success in venture capital, providing 9,000 anonymized founder profiles. State-of-the-art LLMs like DeepSeek-V3 deliver over 6x baseline precision, with most models surpassing human benchmarks.

  • From Limited Data to Rare-event Prediction: LLM-powered Feature Engineering and Multi-model Learning in Venture Capital

    Mihir Kumar, Aaron Ontoyin Yin, Zakari Salifu, Kelvin Amoaba, Afriyie Kwesi Samuel, Fuat Alican, Yigit Ihlamur

    arXiv 2025

    Abstract

    A framework for predicting rare, high-impact outcomes from limited, noisy early-stage data. LLMs turn unstructured founder profiles into 63 trainable features (skill relevance, domain expertise, education level, text embeddings); a layered ensemble of XGBoost, Random Forest, and a Linear Regression meta-model predicts total funding, which a thresholded logistic regression maps to a binary success call. On 10,825 founders with an 8.5% success rate, the pipeline reaches 9.8x-11.1x the random-baseline precision across three held-out subsets at 36% recall, with funding MAPE under 4%. Ablations show LLM-derived features matter most: removing them drops precision from 10.4x to 4.6x. Feature sensitivity puts the startup category list (15.6%) and number of founders as the strongest drivers.
