How can you become a senior data scientist if there are no jobs for juniors
hello, i graduate soon with a computer engineering degree and im checking the specializations with the highest paying salaries (mainly in the uae,ksa and mea) and i stumbled upon data science but as i've read more and more it seems that there are almost no junior level jobs but a lot of senior level jobs, but how does that make any sense if i cant get a junior level job how can i become a senior? unless im mistaken dont u need years of experience to become a senior? and before anyone tells me i understand that i shouldn't choose a career based on money alone but i legit have 0 passion and i love nothing in the workfield atm so this is the most objective thing i can think of and i meant an msc in ds.

D Data cleaning techniques for PDF documents with semantically meaningful parts
I am seeking insights and best practices for data preprocessing and cleaning in PDF documents. I am interested in extracting only the body text content from a PDF and discarding everything else, such as page numbers, footnotes, headers, and footers (see attached image for an example of semantically meaningful sections).
I have noticed that in Microsoft Word, a user can simply drag in a PDF and Word seems to automatically understand which parts are headers, footnotes, etc. I am speculating that Word may be utilizing machine learning techniques to analyze the layout and formatting of the PDF and classify different sections accordingly. Alternatively, Word may be utilizing pre-defined rules or patterns to identify common elements such as headers and footnotes. I know of related techniques for example to extract layout information from receipts and the like (LayoutLM, Xu et al., https://arxiv.org/abs/1912.13318) and tabular data (TableNet, Paliwal et al., https://ieeexplore.ieee.org/document/8978013), but nothing to solve layout extraction in this particular domain.
I am curious to know if there are any techniques or algorithms that can replicate this behavior in Word. Any suggestions or recommendations for data cleaning in PDF documents, would be greatly appreciated.

E FYI: Statistical Rethinking (2023) by rmcelreath
The first pre-recorded lecture from of Statistical Rethinking (2023) by Richard McElreath (MPI EVA) is available now on his Youtube channel Richard McElreath - YouTube. Pre-recorded lectures will be uploaded twice a week. There is a chance to join weekly discussion, but it is already full at the moment.
The course will be about causal inference and Bayesian data analysis. You can find the course materials on GitHub - rmcelreath/stat\_rethinking\_2023: Statistical Rethinking Course for Jan-Mar 2023.

Astrophysics background for data science
Hello all, I have a PhD in Astrophysics and 5+ year of postdoc experience from one of the Ivy league University in the US. Have extensively used python and data statistics for my research. Been looking into data science as a career opportunity. Was wondering if someone from the similar backgrounds can share their experiences in this transition. Any advice? I don’t have any industry experience but can I use my academic experience to apply at mid-level data scientists positions? Any advice would be great.

Let's share some resources to improve out soft-skills
The beginning of the new year is a great time to learn something new (or to improve your knowledge). Soft skills are extremely important to our career, so I suggest sharing some resources (books, courses, blogposts, etc) to improve them.
Some links from me:
* [https://www.howtodeal.dev/](https://www.howtodeal.dev/) Any large project has a lot of people in different positions working on it. This website gives a broad categorization of them and gives suggestions on how to deal with them;
* [https://www.eviltester.com/post/online-presentation-speaking-tips/](https://www.eviltester.com/post/online-presentation-speaking-tips/) \- suggestions on how to make great online presentations (especially actual in post-COVID world)

Please suggest some cool mathematical models that I can 3d print.
I will be getting a 3d printer in the near future. What are some cool and crazy mathematical models that I could print. Link to an .stl file will be great, but I am also looking forward to creating my own models so links to formulas and pictures also appreciated.
I am going to start with platonic solids (nested wireframes maybe), fractal solids (Sierpiński pyramid, mandelbulb), Gömböc, Klein bottle, slide rule etc. But I am looking for more ideas.
Editing to add more ideas: solids of constant width, sphericons
