copy_last_official + 两级增殖重加权(β_type=-3, β_cell=-3,E-S 无放回抽样),不改表达值;测试了针对 de_recovery 的表达修饰(加性斜率平移、乘性增殖放大),全部净负,故保留父机制。

结论(本节点)

本节点尝试在父节点 11 之上叠加"表达修饰"来提升最弱组 de_recovery(父 A 半 51.46 贴地板), 但 A 半查分证明所有表达修饰机制都净负,瓶颈是 cell_state(mmd_u):一旦改动表达值, 细胞立刻偏离冻结分类器学到的 E8.5 流形,cell_state 从 59.64 崩塌,而 de_recovery 只涨 ~0.5。 最终发布版 = 父节点 11 机制(γ=0, ε=0,纯重加权不改表达),A 半 proxy 复现 56.49(与父逐位一致)。

发布的机制(与父节点 11 相同)

  • 基底:inputs_by_time(manifest, include_external=False) 取最新官方输入阶段(proxy/proxy2=E8.5,final=E9.5); 无官方阶段(X3)退回最新任意输入并关闭重加权与表达修饰(纯 copy_last)。
  • 增殖得分 p_i:13 个经典 cell-cycle 基因(Mki67/Top2a/Cdk1/Pcna/Mcm2-7/Ccnb1/Ccnb2/Birc5,运行时按 genes.txt 匹配)log1p 均值。通用细胞周期标记知识,无保留阶段信息。
  • w_type = clip(1 + β_type·(type_mean(p) − global_mean(p)), 0.05, 20);w_cell = clip(1 + β_cell·(p_i − type_mean(p)), 0.05, 20);β_type=β_cell=-3。
  • w = w_type×w_cell,Efraimidis–Spirakis 无放回抽样至 target_n_cells。表达矩阵不修改(保护 covariation/cell_state)。

机制 A — 类型内增殖 OLS 斜率的均匀加性平移 expr[t,g] += ε·(−slope_g),|slope|>thr:

机制 B — 逐细胞乘性增殖放大 X[i,g] *= 1+γ·z_p[i]·corr_g(保稀疏、保 covariation,node7 风格):

-0.20.1055.4851.9660.1855.6853.68

要点:乘性放大成功保住了 covariation(53.3-53.9 ≈ 父 53.5),且 de_recovery 最高到 52.48(+1), direction 也持平/微升到 60.18;但 cell_state 随 |γ| 单调崩塌(-0.2→55.68,-0.8→41.94), 拖累 board 全部 < 父 56.49。加性平移连 covariation 一起毁(ε=1.0 时 covar 15-30)。

教训(给后续节点)

  1. de_recovery 与 cell_state 在 T1 上直接冲突:de_recovery 要真实的 E8.5→E9.5 表达差, 只能靠改表达值引入;但 cell_state(mmd_u) 对任何表达扰动极敏感(γ=-0.2 就 -4,ε=0.1 就 -1)。 每 +0.5 de_recovery 要付 4-17 点 cell_state,净负。不要再用表达修饰刷 de_recovery。
  2. 父节点"只改抽样权重、绝不改表达"是本榜的强局部最优(A 56.49,node 7 A 56.80 在噪声内为全树最高, 但其增益也主要来自权重而非表达)。
  3. 乘性(保零)优于加性(填零):若将来一定要改表达,用乘性放大保 covariation,且 |γ|≤0.1 才可能不崩 cell_state。

验证过 / 没验证

  • 验证过:三视图(proxy/proxy2/X3)跑通 + vec-check ok;发布版 A 半 proxy=56.49 与父逐位一致;运行时 ~4.4 s,内存 <2 GB;seed 确定。
  • proxy2 发布版预期与 proxy 同源(官方 E8.5 基底,忽略 Qiu 外部阶段);X3 退回纯 copy_last(预期 50.00)。
  • 没验证:final 视图(会 copy E9.5 后同样重加权,幅度未测;建议 final 上按输入阶段数收缩 β)。
  • 未使用保留阶段/基因型信息;外部数据(proxy2 Qiu E9.0)显式忽略;prior/ 未读。

下一步建议

  • de_recovery 已确认为"改表达→崩 cell_state"的死路,别再投入。
  • 若要超越 56.49:转向 direction/cell_state 的纯抽样改进(如更细的 per-type β、或按分化轨迹而非全局增殖轴重加权), 或在 final 视图上对 β 做时间跨度收缩以降低过冲。

调研员的计划

名称proliferation-slope uniform type-gene mean shift for DE recovery
动机de_recovery is the weakest group in node 11 (50.99) and across the entire tree (nodes 4/6/7/9/10/11 all 50.0–51.7, within noise of floor 50). The parent ANALYSIS states 'de_recovery 对全局增殖轴重加权不敏感…该组需要不同的机制'. Node 7's per-cell expression amplification (γ=-0.8) changed variance along the proliferation axis but NOT the per-type gene means, yielding only +1.03 de_recovery (noise). DE recovery requires population-level mean shifts per gene, which a uniform within-type shift can provide without altering covariance (adding a constant per type-gene preserves all pairwise covariances exactly).
做法Keep parent node 11's two-level reweighting (β_type=-3, β_cell=-3, E-S sampling) unchanged. After sampling target_n_cells rows, add a post-sampling expression adjustment:

1. For each cell type t with ≥30 sampled cells:
a. Compute proliferation score p (same 13-gene panel as parent).
b. For each gene g, compute OLS slope: slope_g = cov(expr_g, p) / var(p) within type t.
c. Select genes with |slope_g| > thr (initial thr=0.03).
d. Uniform shift: expr[cell, g] += ε × (−slope_g) for ALL cells of type t. This shifts differentiation-associated genes up and proliferation-associated genes down, mimicking E8.5→E9.5 cell-cycle exit.
e. Clip expr ≥ 0.
2. Types with <30 cells: skip adjustment. External/X3 views: skip (pure copy_last fallback).
3. Expression is in whatever space the view provides (log1p typical); shifts are in the same units.

Parameter search (proxy A-half, seed 0):
- ε: start 1.0, search {0.3, 0.5, 1.0, 2.0, 3.0}
- thr: start 0.03, search {0.01, 0.03, 0.05, 0.1}
- Fix β_type=-3, β_cell=-3 from parent (do not re-tune).
- Strategy: single-axis alternating (fix thr, sweep ε; then fix best ε, sweep thr). ≤8 queries for tuning + 2 for proxy2/X3 verification + 1 see…
风险1) Proliferation axis may poorly predict true E8.5→E9.5 DE direction for many genes → shifts in wrong direction → de_recovery drops below 50. Engineer should check de_recovery after first ε=1.0 run; if <49.5, reverse sign (use +ε×slope instead). 2) Large ε may distort expression enough to confuse the frozen classifier → cell_state drops. Monitor cell_state; if it drops >2 from 55.46, halve ε. 3) Node 8 crashed on a related 'typicality weighting' approach—likely implementation complexity. This approach is just OLS + addition, no external deps; Engineer should keep it simple (numpy/scipy only, no sklearn). 4) Uniform shift is crude: real DE is heterogeneous within types. Mitigation: this is a first-order approximation; even +2 de_recovery (noise-level) combined with maintained cell_state/direction/covariation would improve the weighted node score. 5) covariation should be exactly preserved (mathematical guarantee for constant shift), but verify empirically; if it drops, check for clip artifacts at expr=0.

分析结果?分析员写的 ANALYSIS.json:改了什么、各组分数怎么变、假设是否成立、经验和下一步建议。

改了什么在父节点 11 的两级增殖重加权(β_type=-3, β_cell=-3, E-S 抽样)之上实现了两种针对 de_recovery 的表达修饰并做 A 半网格查分:(A) 类型内增殖 OLS 斜率的均匀加性平移(ε/thr/nz_only),(B) node7 风格逐细胞乘性放大 1+γ·z_p·corr_g。所有变体净负,发布版回退到父机制(ε=0, γ=0),故榜分与四组分数与父节点逐位相同(+0.00)。
各组分数的变化cell_state:噪声内(55.46 → 55.46,+0.00):发布版=父机制;A 半试验证明任何表达扰动都单调拉低该组(γ=-0.2 已 -4,ε=1.0 加性平移崩到 23.55)
covariation:噪声内(52.42 → 52.42,+0.00):加性平移会连 covariation 一起毁(ε=1.0 时 15-30),乘性放大可保住(53.3-53.9)
de_recovery:噪声内(50.99 → 50.99,+0.00):发布版未启用表达修饰;A 半内部试验中修饰最多把 de_recovery 提到 52.48(乘性 γ=-0.8),但代价是 cell_state 从 59.64 崩到 41.94
direction:噪声内(56.75 → 56.75,+0.00)
假设是否成立否
经验
  1. 在 T1 上 de_recovery 与 cell_state(mmd_u) 直接冲突:任何改表达值的机制(加性斜率平移、乘性增殖放大)都使细胞偏离冻结分类器的 E8.5 流形,每 +0.5 de_recovery 需付 4-17 点 cell_state,A 半 board 全部低于父基线 56.49(最好 55.48)
  2. 改表达时乘性(保零)优于加性(填零):乘性放大保住了 covariation(53.3-53.9 ≈ 父 53.5),加性平移在 ε=1.0 时把 covariation 毁到 15-30,且 nz_only 变体也只恢复到 30.57
  3. cell_state 对表达扰动极敏感且随扰动幅度单调下降:γ=-0.2 已 -4 点,ε=0.1 已 -1 点;若将来必须改表达,扰动幅度需 |γ|≤0.1 量级才可能不崩
  4. '只改抽样权重、绝不改表达' 是本榜的强局部最优:本节点发布版回退父机制后 A 半复现 56.49 且三视图 vec-check 通过,无回归
  5. de_recovery 各组长期贴地板(全树 50.0-51.7),且已证实无法通过表达修饰在 T1 上换取净收益,不应再向该组投入表达改动类方案
下一步建议
  1. 针对 direction/cell_state 组:做纯抽样改进,如把 β_cell 细化为 per-type 独立值(在 β=-3 邻域按类型逐个网格搜索),不改任何表达值
  2. 针对 direction 组:把重加权轴从全局增殖得分换成类型内分化轨迹投影(如各类型内 pseudotime/分化基因 vs 增殖基因的比值),仍只用于抽样权重
  3. 针对 final 视图(未验证):按输入阶段数或 E8.5→E9.5 时间跨度对 β 做收缩(如 β_final = β_proxy × 0.5)防止重加权过冲,在 final 上小规模验证

最后的回答(摘录)
Done. Final state of `solution/`:

**做了什么**:在父节点 11(copy_last_official + 两级增殖重加权 β=-3/-3,不改表达)之上,按 PLAN 实现了两种针对最弱组 de_recovery 的表达修饰机制并做 A 半网格查分:(A) 类型内增殖 OLS 斜率的均匀加性平移(ε/thr/nz_only 多组),(B) 逐细胞乘性增殖放大 γ·z_p·corr_g(node7 风格,γ/corr_thr 多组)。共 11 次查分。

**查分结果**(A 半 proxy,父基线 56.49):所有表达修饰变体全部净负。
- 加性平移最好 ε=0.1 → 56.07(cell_state 58.59<59.64);ε≥0.3 直接崩到 53 甚至 38(连 covariation 一起毁)。
- 乘性放大保住了 covariation(53.3–53.9)、de_recovery 最高 52.48、direction 微升 60.18,但 cell_state 随 |γ| 单调崩塌(-0.2→55.68,-0.8→41.94),board 最好 55.48 仍 < 56.49。
- 结论:**de_recovery 与 cell_state(mmd_u) 直接冲突**——每 +0.5 de_recovery 要付 4–17 点 cell_state。发布版回退到父机制(γ=0/ε=0),A 半 proxy 复现 56.49,三视图 vec-check ok,无回归。

**下一步最值得试**:放弃用表达修饰刷 de_recovery(已证死路)。转向 direction/cell_state 的纯抽样改进(更细的 per-type β、或沿分化轨迹而非全局增殖轴重加权),以及 final 视图上按时间跨度收缩 β 防过冲。

Final (E8.5→E9.5 two stages): same code applies to the last official stage; if two stages available, could optionally compute slope from the delta between stages, but the within-stage proliferation correlation is the primary mechanism and works identically.\n\nvec-score quick screen: run proxy seed 0 first; if de_recovery < 51.5 (no improvement), abort ε tuning and try thr=0.01 or ε=3.0 before concluding failure.",
  "expected_groups": ["de_recovery"],
  "risks": "1) Proliferation axis may poorly predict true E8.5→E9.5 DE direction for many genes → shifts in wrong direction → de_recovery drops below 50. Engineer should check de_recovery after first ε=1.0 run; if <49.5, reverse sign (use +ε×slope instead). 2) Large ε may distort expression enough to confuse the frozen classifier → cell_state drops. Monitor cell_state; if it drops >2 from 55.46, halve ε. 3) Node 8 crashed on a related 'typicality weighting' approach—likely implementation complexity. This approach is just OLS + addition, no external deps; Engineer should keep it simple (numpy/scipy only, no sklearn). 4) Uniform shift is crude: real DE is heterogeneous within types. Mitigation: this is a first-order approximation; even +2 de_recovery (noise-level) combined with maintained cell_state/direction/covariation would improve the weighted node score. 5) covariation should be exactly preserved (mathematical guarantee for constant shift), but verify empirically; if it drops, check for clip artifacts at expr=0."
