    Random forest algorithm identifies miRNA signatures for breast cancer detection and classification from patient urine samples by Jochen Maurer, Matthias Rübner, Chao-Chung Kuo, Birgit Klein, Julia Franzen, Julia Wittenborn, Tomas Kupec, Laila Najjari, Peter Fasching, Elmar Stickeler

    Published 2024-12-01
    “…Design and methods: Here, we present the first proof-of-concept approach for sequencing miRNAs in female urine to detect breast cancer and, subsequently, intrinsic subtype-specific miRNA patterns and implement in this regard a novel random forest algorithm. To this end, we performed miRNA sequencing on 82 urine samples, 32 samples from breast cancer patients (9× luminal A, 8× luminal B, 9× triple-negative, and 6× HER2) and 50 healthy control samples. …”

    Impact of NWP Model Configuration and Training Sample Characteristics on Random Forest‐Based Day‐1 Convective Outlook Guidance by Aaron Johnson, Xuguang Wang

    Published 2025-02-01
    “…However, within the 2019/2021 data set, training on cases from a different year than the year being forecast also leads to statistically significant degradations of skill, apparently at least in part due to the different sample climate between 2019 and 2021. For this particular NWP (Numerical Weather Prediction) model configuration change, the consistency in sample climate between training and forecast cases is at least as important as consistency in model configuration. …”
