Clustering of Twitter data with Python, K-Means, and t-SNE — In the article “What People Write about Climate” I analyzed Twitter posts using natural language processing, vectorization, and clustering. Using this technique, it is possible to find distinct groups in unstructured text data, for example, to extract messages about ice melting or about electric transport from thousands of tweets about…

Clustering of Twitter data with K-Means, TF-IDF, Word2Vec, and Sentence-BERT — What do people think and write about the climate, pandemics, war, or any other burning issue? Questions like this are interesting from a sociological perspective; knowing the current trends in people’s opinions can also be interesting for scientists, journalists, or politicians. But how can we get answers? Collecting responses from…

Gettings statistical insights with Python, Pandas, and Bokeh — Germany is not only the largest economy in Europe, but it is also a country with beautiful landscapes and an interesting culture. Unsurprisingly, Germany is a popular destination for tourists and expats from all over the world. Exploratory data analysis of the German housing rental market can be interesting not…

Running UNIX BSD 2.11 on your PC — Even if you never heard about Linux or Unix, highly likely you were using it within the last 10 minutes: all Android smartphones are powered by Linux, and all Apple devices are using parts of the BSD kernel in their OS. And probably, there are several other Linux devices in…

Data analysis and visualization with Python, SQLAlchemy, and Bokeh — When was the first electric car registered? (Spoiler: it was much earlier than most people may think.) Which cars are more expensive, the electric Porcshe or Jaguar? Exploratory data analysis (EDA) is not only an important part of building every data pipeline, but it is also a pretty interesting process…

Nowadays millions of people are using Apple laptops, but how did this era actually start? I will test a PowerBook Duo laptop from Apple, released more than 30 years ago, in 1992. I will also show how to write programs for it, and I will test how different apps like…

A deep learning-based generative art is an active topic of research nowadays. And as usual, the best way to learn something is to try it on your own. Some models, like OpenAI’s DALL-E 2, require registration and can be used only online, but some others can be used locally, which…
