目前还回答不了的一些问题Questions I am currently unable to answerQuestions I am currently unable to answer目前还回答不了的一些问题

一份研究陈述只有在它承认哪些还没解决的时候才有用。下面三个项目按「我敢在公开场合为其中多少辩护」排序。

A research statement is only useful if it admits what is still open. The three projects below are ordered by how much of them I would defend in public.

01 / 研究方向INTERESTS
是领域,不是主张subject areas, not claims

研究方向InterestsInterests研究方向

  • 作物表型Crop Phenotyping

    把原本只能手工量的东西从田里取出来——根系、冠层、一个生长季里的变化——而不是让一个人坐下来一株株数。

    Getting measurements out of a field that would otherwise be taken by hand — root systems, canopy, growth over a season — without asking a person to sit and count.

  • 农业图像Agricultural Imaging

    在田间真实存在的条件下做检测与分割:叶片互相遮挡、光照一直在变,照片也永远不会像基准数据集那样干净。

    Detection and segmentation under the conditions a field actually has: overlapping leaves, changing light, and photographs that will never be as clean as a benchmark.

  • 统计学习Statistical Learning

    一个被报告出来的提升,在固定评估协议之后还能剩下多少;以及一个小而吵的样本能诚实支撑多少信心。

    How much of a reported improvement survives a fixed evaluation protocol, and how much confidence a small, noisy sample can honestly support.

  • 有限群论Group Theory

    从消失元的结构反过来刻画有限群;以及追问一个融合系统在什么条件下会从它的来源群继承超可解性。

    Characterising finite groups from the structure of their vanishing elements, and asking when a fusion system inherits supersolvability from the group it came from.

  • 科研工具Research Tooling

    让别人能真的把方法跑起来的界面与流程。一个除了自己没人跑得起来的方法,还不算产出了结果。

    Interfaces and pipelines that let the next person run the method. A method nobody else can run has not produced a result yet.

R.01 / 2025 — presentongoing

从图像序列中恢复根系结构Root structure recovery from image sequences

问题Question

在不逐帧人工标注的前提下,低成本采集的图像里能还原出多少细根结构?

How much fine-root structure can be recovered from low-cost captures without manual annotation of every frame?

做法Approach

带显式遮挡模型的多帧融合,以标注方差为基线来评估,而不是拿一份手工标注当标准答案。

Multi-frame fusion with an explicit occlusion model, evaluated against an annotation-variance baseline rather than a single hand-labelled set.

R.02 / 2025writing

融合系统与超可解性Fusion systems and supersolvability

问题Question

在 F_S(G)-融合系统中,哪些结构性条件会强制超可解性?

Which structural conditions force supersolvability in F_S(G)-fusion systems?

做法Approach

群论论证;当前这一版在尝试削弱主定理的假设条件。

Group-theoretic arguments; the working revision is an attempt to weaken the hypotheses of the main theorem.

R.03 / 2025complete

植物病害分割中的基准稳定性Benchmark stability in plant disease segmentation

问题Question

固定评估协议之后,已发表的提升还能剩下多少?

How much of a reported gain survives a fixed evaluation protocol?

做法Approach

把一批已发表的配置放到同一套划分和同一套预处理下重跑,报告前后的相对排名。

Re-ran a set of published configurations under one split and one preprocessing pipeline; reported the relative ranking before and after.

03 / 方法THE METHOD
决定其余一切的那一部分the part that decides everything else

方法The MethodThe Method方法

这里每个项目最后都会汇到同一个第一步:先确定测量本身给误差贡献了多少。这个数字出来之前,方法之间的比较只是噪声之间的比较。

Every project here converges on the same first step: establish what the measurement itself contributes to the error. Until that number exists, comparisons between methods are comparisons between noise.

A reminder that increasing n does not reduce a shared measurement bias.
