Hello my name is Libana Roscher
2
and I want to present our paper Controlled multimodal image generation for plant growth modeling
3
which was presented at the international conference on pattern recognition last summer.
4
So when we have a look at such an aquaculture field
5
and we work with robotics and with machine learning methods for phenotyping
6
we can ask ourselves different questions
7
so for example we can ask what is on the field
8
which is a typical classification task
9
or we can ask what is the yield in a specific area
10
which is a typical regression task
11
or we can ask ourselves what will a plant look like in the future
12
and this is a forecasting tasks
13
and this is exactly the question we addressed in our paper
14
so imagine the following scenario you already know that
15
when plants grow closely together this can be very beneficial
16
so for example it can increase the biomass the crucial question is now what is actually a good mixture
17
and so what you can do is you can test different mixtures then you can collect data
18
and then you can learn a model from this information
19
and this model relates the information from what we have measured to a parameter like the biomass
20
so you have a relationship between the mixtures and the biomass
21
and then the good thing is this model can be applied to new mixtures
22
and these new mixtures were not tested yet in the field before
23
so you get an idea what potential good mixtures are
24
And one problem is now that one might be interested in the biomass
25
and the other might be interested in the spread of diseases.
26
So it would be good to combine this and to get complete information.
27
And this can be done if you model the whole appearance with plants, that means if you generate images.
28
And with this you are flexible in what you do with the result
29
because it can be treated such as an artificial sensor measurement.
30
So in order to generate such images we used
31
so -called generative adversarial networks illustrated here and this is a neural network consisting of two parts.
32
So one part is the generator G and this generator is responsible to generate images.
33
The other part is the discriminator, and the discriminator helps to train the generator to generate really good images.
34
The discriminator does it by trying to distinguish between real images and images which were generated by the generator.
35
So in the best case, the generator generates such good images
36
that the discriminator can no longer distinguish between a real image
37
and an image which was generated but there's one crucial thing
38
which is important for our application
39
so we do not want only want to generate an arbitrary
40
nice -looking image we want to condition on specific factors on specific things
41
and one important thing is we want to condition on the appearance of an of an additional input image
42
which is from an earlier point in time
43
and the second important thing is we want to condition on
44
so -called factors of variation and these factors of variation are factors
45
which influence the appearance of the of the plants
46
and the novelty of our paper is exactly this part
47
because on the one hand we learned the representation
48
which is useful for the machine learning model but on the other side it was
49
Because we can also easily and intuitively change these factors of variation so that we can produce different scenarios, different outcomes.
50
And so here you can see results of
51
which we presented in our paper where we generated images with chain factors of variation.
52
So our dataset contains UAV images, which were captures in Kampus -Klein -Altendorf,
53
where we have different mixtures of spring wheat and faba bean.
54
And we also collected different factors of variation, which belong to these mixtures.
55
And they are illustrated in green and light blue and in dark blue.
56
And on the left, you can see the input image, which is from an early growth stage.
57
And this is the real scene from a later growth stage and the measured factors of variation.
58
And these images are all generated images.
59
So here we change the factors of variation.
60
So for example, on the very right image, you can see we set all factors of variation for Faba bean to zero.
61
And actually there are no Faba bean plants in the generated image.
62
So we can clearly control and manipulate how the images can be generated it
63
and from these images we can now derive specific parameters pointing
64
us to potential promising mixtures we can later test in the
65
field with this thank you very much for listening you can find the paper by scanning the qr code
66
and if you are more interested in this research direction you can go to our website
67
or you can have a look in my YouTube channel.

Thanks a lot!
本节课学习内容
通过观看这段关于植物生长建模的科技视频,你将练习听懂学术演讲中的英语表达,同时提升影子跟读法(shadow speak)的技巧。视频语速适中,用词专业但清晰,非常适合训练听力和口语的同步性。跟着视频模仿发音、语调,还能积累科技领域的实用词汇,一举多得!
核心词汇与短语
- generative adversarial networks:生成对抗网络(AI领域术语,注意连读发音)
- factors of variation:变异因素(学术讨论中常用,重音在“variation”)
- phenotyping:表型分析(生物学词汇,练习咬字清晰)
- condition on:以……为条件(科技英语中表“基于”,注意介词搭配)
- forecasting task:预测任务(实用短语,适用于各类场景)
练习技巧
视频中演讲者语气平稳,语速中等,很适合影子跟读法(shadowspeak)练习。建议先完整听一遍,熟悉内容后,逐句暂停模仿:注意模仿重音和停顿,比如“the generator is responsible to generate images”中,“responsible”和“generate”要重读。遇到长句(如介绍模型的部分),可拆分练习,先跟后半句,再连起来。每天坚持10分钟,既能提高英语发音,又能熟练掌握学术英语的表达节奏。记住,犯错是进步的开始,大胆开口,你会越练越棒!
看视频学英语就是这么简单,利用好这段素材,让影子跟读法成为你的口语提升利器吧!
什么是跟读法?
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧,最初开发用于专业口译员的培训,并由多语言者Alexander Arguelles博士普及。这个方法简单而强大:您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同,跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性,语调,节奏,连读,听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
