+量子概率分布过于集中（标准差仅0.052），88.8%的日期被判为"可交易"（prob>0.45），NOOP几乎不触发——模型在退化标签上缺乏区分能力。作为对比，经典LogReg的概率标准差为0.112（区分度更大），但NOOP后同样亏损（-39.8%），说明标签退化影响的是所有模型而非量子独有。 + +**假说2 — 训练数据不足（Insufficient Training Data）** +

+V4_EX1内置4层风控（BIAS13保险丝/EX1早清/DHU65上影线卖出/半卖机制），其中BIAS13本身就是一种市场择时NOOP（4年触发4天）。量子模型学到的市场择时信号可能被这些机制部分吸收。 + +**假说4 — 超参数未优化（Hyperparameter Sensitivity）** +

cross-strategy validation + results update MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add stock_level_filter.py: per-signal NOOP (individual stock filtering) - 3 GAP thresholds (2.0/2.5/3.0%) with threshold scans - GAP2.0 Q/L=2.52x (best quantum-vs-classical ratio) - Layer reversal pattern: dense signals → stock-level advantage; sparse signals → day-level advantage - Add WP stab6 cross-strategy validation (negative result) - V1/V2/V3 grid scan (2/4/6/8 qubits × C=0.1/1.0/10.0) - All 12 configs Q/L < 1.0 → classical outperforms quantum - Root cause: signal pool homogenized by triple pre-filter - Update results.json: +stock_level_filter +gap_threshold_day_level_scan +wp_stab6_validation - Update README: 5b section (stock-level + layer

stab6的三重过滤），量子核退化为经典方法的水平甚至更差。这一发现为量子核SVM的应用边界提供了明确的判据：**量子核适用于"广撒网"型策略的信号筛选，不适用于"精筛"型策略的二次过滤。** + +--- + ## 六、系统化优化方法论 为找到全局最优配置，我们对系统的四个维度进行了穷尽式扫描，每阶段独立验证后逐步锁定最优参数。 @@ -474,12 +576,13 @@ scale: π
