Assertion Evidence Approach

The key ideas behind assertion-evidence are to:

1. Build your talks on messages, not topics

意思是:汇报不是按“话题”堆材料,而是按“你想让观众记住的信息”来组织。

普通做法:

Method
Results
Background

这种标题只是 topic,信息量很低。

更好的做法:

Our method reduces annotation cost by using reports as supervision
Model performance improves most on rare diseases
CT scans provide 3D anatomical information from X-ray projections

这种标题本身就是一个 message,观众看标题就知道这一页的核心结论。

2. Support messages with visual evidence, not long text

** It is important to carefully choose visuals that support the message and avoid those that might be distracting or irrelevant. **

有了 message 之后,slide 正文不要放大段文字,而要放能支撑这个 message 的视觉证据,比如:

  • 图像
  • 流程图
  • 实验结果图
  • 对比图
  • 简化表格
  • 模型结构图
  • 高亮后的关键区域

例如你的标题是:

CheXzero learns from radiology reports without manual labels

那么正文最好放一个训练流程图:
X-ray image + report → model training → pathology prediction

而不是写一大段解释模型怎么训练。

slide 的作用不是替你写讲稿,而是给观众一个“视觉锚点”。

3. Explain this evidence by fashioning words on the spot

这句话的意思是:具体解释由演讲者现场说,而不是全部写在 slide 上。

也就是说,slide 上只放:

  • 核心结论
  • 支撑结论的图
  • 少量关键词

然后你现场解释:

这张图左边是输入数据,中间是训练过程,右边是模型如何根据 positive prompt 和 negative prompt 输出 disease probability。

这样观众的注意力在你身上,而不是低头读满屏文字。

Example里面的script 对应的是good slide的script

Example 1

Script: “A CT (computed tomography) scanner is a specialized medical imaging device that uses x-ray technology to create detailed 3D images of the inside of the body. The CT machine consists of a large, donut-shaped x-ray machine that rotates around the body while the patient lies on a table that slides into the center of the machine. As the machine rotates, it emits a beam of x-rays through the body, which is then detected by detectors on the other side of the body. The data collected by the detectors is then used to create a 3D image of the inside of the body.”

Example 2

Script: “First, the CheXzero training pipeline involves using raw radiology reports as a natural source of supervision, allowing the model to learn features from them. Then, to predict pathologies in a chest X-ray image, we generated a positive and negative prompt for each pathology, such as 'consolidation' versus 'no consolidation’. By comparing the model output for the positive and negative prompts, the self-supervised method can compute a probability score for the pathology, which can then be used to classify its presence in the chest X-ray image.” ![](/assets/Pasted image 20260618005419.png)

Make Texts Telegraphic

核心思想:
Slides 上的文字应尽量简短,像“电报”一样只保留关键信息,避免完整长句和大段文字。

写法原则

  • 用短语,不用完整句子
  • 只保留关键词
  • 省略可由上下文推断的信息
  • 文字用于辅助视觉证据,而不是替代讲解
  • 保持简短,但不能含糊

示例

差:

The model is trained on raw radiology reports, which provide a natural source of supervision without requiring manual labels.

好:

Raw reports as supervision
No manual labels

Takeaway

Slide 文字不是论文正文,而是提示词。
少写文字,把详细解释留给演讲者。

Introduce Texts Sequentially

slide 文字与版式的小技巧

1. Serif 和 Sans-serif 字体搭配使用

Serif font 是有衬线字体,比如 Times New Roman,字母笔画末端有小装饰。
Sans-serif font 是无衬线字体,比如 Arial、Helvetica,字形更简洁现代。

常见用法:

  • 标题:sans-serif,简洁、醒目
  • 正文/说明:serif 或较轻的 sans-serif
  • 重点:用字体粗细或颜色区分

Serif fonts are typically used for body text because they are easier to read in large blocks of text due to the extra details on the letters. Sans-serif fonts are often used for headings and other large blocks of text because they are simpler and more modern-looking.

重点是:一套 slides 内保持统一。不要每页换字体,也不要混用太多字体。


2. 使用白色背景

白色背景适合学术 slides,原因主要有三个:

第一,可读性强
深色文字放在白底上,对比明显,远处也容易看清。

第二,显得专业
白底比较中性,不会抢内容的注意力。

第三,保持简洁
复杂背景容易干扰图表、文字和实验结果。

所以除非有特殊设计需求,学术汇报一般优先选择白色或接近白色的背景。


3. 文字颜色控制在两种左右

slides 上不要用太多颜色。颜色太多会让观众不知道哪里是重点。

推荐做法:

  • 黑色/深灰:普通文字

  • 一种强调色:关键词、重要数字、重点结论

例如:

Baseline accuracy: 72%
Our model: 86%

这里可以只把 86% 或 improvement 用强调色突出。

颜色的作用是建立层级,而不是装饰页面。


slide 底部可以放两个东西:

引用 citation

如果用了论文、数据集、图表或别人的方法,要在 footer 里标注来源。

这样做有两个好处:

  • 显得严谨可信

  • 避免来源不清

例如:

Rajpurkar et al., 2022
NIH ChestX-ray14 dataset

页码 page number

页码方便听众提问时定位:

我想问第 12 页那个结果……

也方便你自己控制进度和跳转。


在 presentation 开头放一页 outline slide(大纲页)

核心目的:先告诉听众这场汇报的结构,让他们知道接下来会听到什么,以及各部分之间是什么关系。

1. Outline slide

比如研究汇报可以这样组织:

## Outline

1. Motivation
2. Method
3. Experiments
4. Results
5. Discussion

更好的版本可以写得更有信息量:

## Outline

1. Why label-efficient medical AI matters
2. How reports provide natural supervision
3. Experiments on chest X-ray classification
4. Key findings and limitations

3. 使用建议

Outline slide 不要写得太细。
一般 3–5 个部分最合适。

不要这样:

1. Background
2. Related Work
3. Dataset
4. Preprocessing
5. Model
6. Training
7. Evaluation
8. Results
9. Ablation
10. Conclusion

太多条会让听众记不住。

更好的是合并成高层结构:

1. Problem and motivation
2. Method overview
3. Experimental evidence
4. Takeaways

Exercise 1

![](/assets/Pasted image 20260618012200.png)

Reasoning:

  • Eliminated unnecessary points that can be iterated on by the speaker
  • Created object representations of each concept with the key word bolded with the main idea

Exercise 2

![](/assets/Pasted image 20260618012221.png)

Reasoning:

  • More descriptive title
  • Less text
  • Essential components extracted from figure with color
  • Kept only orders of magnitude from the table
