Introduction: By studying Professor Andrew Ng's courses, the following three aspects are summarized: first, the systematic method of reading a series of documents to increase knowledge in a certain field; Second, how to read a research paper correctly; Third, visit online resources to help search for papers and key information.

"Wisdom is not something you can learn, but something you need to pursue all your life."

-Albert Einstein

One will naturally learn the skills and habits displayed by the people around him, which is why most doctoral students can acquire the skills to effectively understand the contents of research papers. But most people are not doctoral students, so how can ordinary people gain the ability to read research papers and understand all aspects?

Read research papers

If some practitioners are talented in the specialization of machine learning, it is very beneficial to them. For example, having general knowledge in the field of computer vision is commendable, but having professional knowledge and skills in key technologies (such as attitude estimation) will attract companies and organizations looking for employees in this field.

Take the topic of attitude estimation as an example to guide how to read research papers related to the topic.

1. Collect the resource set of the topic. Resource forms can include: research papers, media articles, blog posts, videos, GitHub libraries, etc.

? Google's search for "attitude estimation" will display first-level resources containing topic-related information. The goal of the first step is to organize all related resources, such as YouTube videos, implementation documents and research papers. At this stage, you think there is no limit to the number of important resources, but please make sure to create a "candidate list" for useful papers, videos and articles.

2. Dig up the resources that you think are related to the topic. It is very important to record your understanding of each candidate resource. Andrew Ng suggested drawing a table according to his understanding of resources, as shown below.

Every article added to the list should browse at least 10-20% of the content, so as to ensure that enough introductory content is known in the identified resources and its relevance can be accurately evaluated.

? For papers/resources that have been determined to be highly relevant, it is recommended to have a deep understanding. Finally, I got some suitable resources that I fully understand.

? You may ask yourself, "How many papers/resources are enough to read? I don't know the answer, but Andrew Ng does. According to Andrew Ng, understanding 5-20 papers can show a basic understanding of the topic, which may be enough to promote the implementation of technology. Reading 50- 100 papers can give you a good understanding of this field. After browsing resources and extracting important information, the table may look like the following:

3. This is a quick skill observed by the author, which is very useful for understanding research papers. This step is to make structural comments and summarize the key findings, achievements and technologies in the paper in your own words.

? The following steps will focus on how to read a research paper.

Reading a research paper only once can't achieve the purpose of understanding. Andrew Ng believes that reading a paper word for word at a time is not the best way to form an understanding. If you want to understand the content well, you should read the paper at least three times.

4. Read the following parts of the text for the first time: title, abstract and pictures.

5. For the second time, read the following parts first: introduction, conclusion, pictures (read it again), and then browse the rest of the paper.

The introduction and conclusion of the paper include a brief introduction to the overall content of the article and a summary of the research results. These sections usually only provide key information, without supplementary information. As a reader, this is beneficial because it can grasp the key information needed to read other parts of the paper.

6. For the third time, read through the full text, but skip all unfamiliar and complicated mathematical calculations or technical formulas. You can also skip unfamiliar terms and techniques.

7. You can read several papers with in-depth research in a certain field. These extra points will mainly focus on the understanding of mathematics, technology and unfamiliar terms in the text.

? For those who usually read information and engineering research papers, in-depth research can be very time-consuming, especially when there are still 20 papers to read.

? The author introduces the original paper of LeNet convolutional neural network to start the introduction process of this paper, and summarizes the key contents in the notes, and then transforms them into a series of medium-sized articles.

"The process of learning is gradual, not overnight."

Andrew Ng

In the field of machine learning and computer vision, the author is still a novice and has a lot of unexplored knowledge (conservative statement). However, the author believes that no matter in which field, as long as we persist in exploring knowledge, we can gain understanding and professional skills beyond ordinary people.

? Judging from the skills introduced by Andrew Ng, the author should read at least four papers every month and understand them. To tell the truth, it took the author 1 week and a half to finish reading LeNet's paper. But the more times you read, the faster and better you can read and understand research papers.

? Andrew Ng said that he always read with a batch of research papers. Andrew Ng is an outstanding talent in the field of machine learning. Therefore, the author believes that imitating his habits and learning skills will be very beneficial to his study trip.
