#码力全开·技术π对#reCAPTCHA Enterprise分数漂移如何动态调整验证阈值？

# 伪代码示例：基于历史分数分布的动态阈值计算
def calculate_dynamic_threshold(historical_scores, sensitivity=0.1):
    mean_score = sum(historical_scores) / len(historical_scores)
    std_dev = calculate_std_dev(historical_scores)
    # 根据历史分布动态调整阈值
    return mean_score - (sensitivity * std_dev)  # 可调整sensitivity参数
