肽-蛋白亲和力模型在不同数据移位下进行基准测试

研究人员对各种肽表示法和回归器在预测肽-蛋白亲和力方面的性能进行了基准测试,结果表明,根据评估是否涉及肽相似性移位、靶点内预测或留靶点出场景,模型性能差异很大。在 60 种配置中,平均 Spearman 相关系数在 0.462 到 0.669 之间。研究发现,ECFP-16 指纹与随机森林回归器在插值和靶点内预测方面表现最佳,而在排除靶点序列时,HELM-BERT 嵌入与 Extra Trees 表现最佳。研究结果表明,肽-蛋白亲和力基准测试应将数据分区与预期用例对齐,并联合考虑数据规模、分子表示和下游学习器。 AI

影响 强调了在科学研究中,尤其是在药物发现和生物信息学领域,对人工智能模型进行稳健评估方法的重要性。

    跨肽和靶点移位肽-蛋白亲和力预测的基准测试

    arXiv:2608.30175v1 Announce Type: new Abstract: Peptide-protein affinity models are often evaluated with a single data split, obscuring whether they interpolate among measurements for observed targets or generalize across peptide or target shifts. We integrated three sources of q…
