Biologically-informed neural networks (BiNNs) show promise for biological data analysis. Dataset characteristics like sample size and feature sparsity significantly impact BiNN performance, guiding future model development.

Area of Science:

  • Computational biology
  • Bioinformatics
  • Machine learning

Background:

  • Biologically-informed neural networks (BiNNs) provide interpretable models for biological data.
  • Understanding dataset requirements for optimal BiNN performance is crucial but lacking.
  • Previous work utilized P-NET, a BiNN, for prostate cancer metastasis prediction using somatic data.

Purpose of the Study:

  • To develop simulation frameworks for evaluating factors influencing BiNN performance.
  • To assess the impact of integrating germline and somatic data on prostate cancer metastasis prediction.
  • To provide a principled framework for benchmarking BiNNs and understanding their data dependencies.

Main Methods:

  • Developed two simulation frameworks to test BiNN performance under varying conditions (signal type, strength, sparsity, sample size).

  • Empirically evaluated the P-NET model by integrating germline and somatic data for prostate cancer metastasis prediction.
  • Analyzed factors limiting BiNN performance, including sample size, signal strength, and feature sparsity.

    • Main Results:

    • BiNN performance is limited by small sample size, weak signal strength, and extreme feature sparsity.
    • Simulations suggest BiNNs may favor linear over nonlinear signals.
    • P-NET showed poor performance on sparse germline data; integration with somatic data did not improve prediction but enhanced interpretation.

    Conclusions:

    • Simulation frameworks enable systematic evaluation of dataset characteristics affecting BiNNs.
    • Germline data integration did not improve predictive accuracy but enhanced model interpretability.
    • These findings provide a foundation for developing and benchmarking BiNNs for biological data analysis.
