Are you a #Python enthusiast? Here are the top 5 most useful scripts in Python that you should know!
💪🏽

1. Web Scraping: Python offers a powerful library called BeautifulSoup that allows you to extract data from HTML and XML files. With this library, you can easily scrape data from websites and use it for various purposes like data analysis and machine learning.
2. Data Visualization: #Python has several libraries like #Matplotlib, #Seaborn, and Plotly that make data visualization easy and effective. You can create beautiful and interactive graphs, charts, and maps with just a few lines of code.
I am a great fan of the @Medium platform and know its subscriber for almost a year now. It's part of my daily routine to go through its daily recommendations every morning. Here is my collection of bookmarked articles maybe someone will find it useful, so sharing the links 1/n
Happy to announce my new course Mapping and Data Visualization with #Python. This has been in the making for over a year and excited to be able to share it with the world! The full course is free for self-study and shared under an open license. An overview thread below 👇 1/n
We start with the overview of the Python data visualization landscape and zero in on the core libraries for mapping. Day 1 covers vector data visualization with #Maptplotlib, #Pandas, #GeoPandas, and #Contextily (2/n)
Day 2 starts with a deep dive into XArray and raster data visualization. We use #Xarray, #rioxarray and #CartoPy to visualize elevation and gridded climate datasets and learn some advanced #Matplotlib tricks. (3/n)
Interested in learning more about #DataScience, #MachineLearning or #AI? I’ve got a few places and resources for medics to start with. Anyone can do it with enough time and effort! Soon enough you’ll be making your own neural networks

2/16. Everyone has their preferences with programming languages. However if you’re starting from scratch, I highly recommend #Python. It is easy to learn, has a wide variety of applications and you will find it is much easier to perform even the most basic of statistics.
3/16. It also gives you access to multiple libraries that are used heavily by the machine learning community such as #Keras, #TensorFlow and #PyTorch.
[Data Analysis] 🧵
Exploratory data analysis is a fundamental step in any analysis work. You don't have to be a data scientist and be proficient at modeling to be a useful asset to your client if you can do great EDA.
Here's a template of a basic yet powerful EDA workflow👇

EDA is incredibly useful. Proper modeling CANNOT happen without it.
The truth:
Stakeholders NEED it far more than modeling.
EDA empowers the analyst with knowledge about the data, which then moderates the #machinelearning pipeline

While #pandas and #matplotlib are key to good EDA in #python, the real difference are the QUESTIONS you ask to your dataset.
As in all things, these tools are just tools. The real weapon is the analyst. You are in control, not the dataset.

If you want to learn about #bioimageanalysis I've written a free & open textbook that tries to help:

Thanks to the wonder of @ExecutableBooks & other modern magic it's not quite like a normal book... (thread)

First, the book tries to cover the main concepts, independently of any software, in a practical way.
This includes common pitfalls & problems, like data clipping, that can doom analysis from the start (2/n)

It also includes tricky stuff important for a lot of microscopy image analysis, like noise distributions & the signal-to-noise ratio... (3/n)

There are many correct answers.
But the most fascinating one is: << sines & cosines >>

*Any* image can be reconstructed from a series of sinusoidal gratings.
A sinusoidal grating looks like this…
#sinusoidal #grating
A sinusoidal grating looks like this…
#sinusoidal #grating
It’s called a sinusoidal grating because the grayscale values vary according to the sine function.
If you plot the values along a horizontal line of the grating, you’ll get a plot of a sine function

If you want to create great data visualizations, you need to understand color palettes.

For data that has a sequential ordering (i.e., low to high), you should use sequential color scales.

Sequential color scales incrementally change saturation or lightness.
For example, this is a red-sequential color palette:

Will Slovakia avoid „Czech scenario“?
Health minister #marekkrajčí 16.10. first time publicly compared the second wave COVID-19 trends in Slovakia and Czech republic in a chart showing that Slovakia is following the scenario in Czech republic with a delay of 2~3weeks.:
Health minister #marekkrajčí 16.10. first time publicly compared the second wave COVID-19 trends in Slovakia and Czech republic in a chart showing that Slovakia is following the scenario in Czech republic with a delay of 2~3weeks.:
Trend chart from few days ago (22.10.) was even worse and clearly showing that Slovakia is repeating the Czech scenario:
Somewhere here we should be looking for motivation of the government in Slovakia and prime minister #igormatovič to solve the problem of rising second wave of epidemics and dark vision of collapsing health care by unusual way - #masstesting in combination with limited lockdown.

If you are using matplotlib in your day to day coding activity and didn't no the crux of it, I want to you take a look at this below thread. I'm sure you will learn and apply it.
So, here is what all we need to know about matplotlib, an excellent visualization library in python

1. In this thread we will go through some basic patterns and practises to help you get started with the library
It will basically help us plot the data into the figures and can contain axes, i.e. an area where points can be specified in x/y/z co-ordinates
First let's import it

2. The simple way of creating axes is using pyplot.subplots and we can Axes.plot to draw some data on the axes.
Below is how we can do it.

I used Matlab for image processing for years. Tried to switch to Python 10 years ago but too many tools were still missing. Tried again 5 years ago and haven't touched Matlab ever since! The combination scikit-image + @ProjectJupyter was a real game-changer! A few more things:
On top of the great classics scientific stack (#numpy, #scipy, #pandas, #matplotlib) there's an entire ecosystem of new tools to handle all sorts of complex problems. E.g. #napari to visualize and annotate multi-dimensional data. @dask_dev to handle very large images.
Complex ML tools for image denoising like content-aware image restoration #CARE (github.com/csbdeep/csbdeep) or point-scanning super-resolution #PSSR (github.com/BPHO-Salk/PSSR) which are documented as Jupyter notebooks that really work "out of the box".
