This is a web site on some Data Science topics.
It includes content that I taught during an academic course on ‘Data science in Python’ in 2022 and 2023 leading to a bachelor degree.
The value proposition of this page is to show how the various techniques are applied to get to a meaningful analysis of data. For each detail, I recommend to look it up on the respective page or forum.
At this start of 2024, I am preparing for the repetition of this course on ‘Data Science in Python’.
Setup and Coding
Okay, let’s get started with the Setup 2024 for Pandas and Plotly on Ubuntu
Mostly, I use Python, Pandas and Plotly here.
- Python - Some Python for use with Pandas - Lists, dictionaries, comprehensions, …
- Pandas - Overview - Create, work on columns, …
- Plotly - Configurations - Configure graphs, …
Special topic of interest:
- Pandas - Rows - How to delete the last row of a Pandas dataframe? Special topic of interest:
- Pandas running in a Docker container - How run a Python program using Pandas in a Docker container?
Results
First Names
Let’s start with a data set that is straightforward to consume and to visualize.
The statistics department in Scotland has a great website from which a lot of interesting data can be downloaded, e.g. Birth names
How does my first name compare to the currently most popular male first name?
Well, my first name has some potential for growth. However, considering the increasing diversity of names and hence the lower maximum values for the top names, the difference to the top names is getting smaller.
More on the technical part of this analysis and more on first names can be found here: Pandas - Analysis first names
Modelling - Time series
- Time Series - How to work with time-dependent data?.
Modelling - Categorizations
- Categorization - How to cluster and categorize?
Continue on Categorization …
Machine Learning (i.e. no neuronal networks) concludes the part on Python. (No PyTorch here.)
Julia
In 2022 and 2023, Python was sufficient for all my requirements. No updates hence on my pages on Julia dataframes. The content on Julia reflects my version and my knowledge of Julia as of 2021.
Here are the pages on Julia dataframes you were interested in 2023.
- Julia Dataframes - Columns - How to work on columns of a Julia dataframe?
- Julia Dataframes - Rows - How to work on rows of a Julia dataframes?
- Julia Dataframes - Transpose - How to transpose a Julia dataframe?
- Julia Dataframes - Operations - How to operate on a Julia dataframes?
- Julia Dataframes - Dataframe - How to work on the complete Julia dataframe?
- Julia Dataframes - Visualization - How to visualize a Julia dataframe?
