UnverifiedIC通常用Pearson相关系数计算，取值范围-1到1，日均IC稳定达到0.03-0.05即被认为具有统计意义，顶级因子也很少超过0.177% similarUnverified不同归一化方案对同一模型的IC影响可达0.01-0.03的量级75% similarUnverifiedAn IC_IR (Information Ratio) greater than 0.5 is considered the threshold for a factor to have stable predictive power.67% similarUnverifiedICIR是平均IC除以其波动，类似夏普比率逻辑，ICIR高于0.5通常被认为值得进一步研究66% similarUnverifiedCertain AI capabilities are nearly zero when model scale is below a specific threshold, then rise sharply once the threshold is crossed, exhibiting a nonlinear 'phase transition' characteristic.66% similar
