It is not news that developing Machine Learning algorithms requires data, often a lot of data. Collecting this data is not trivial, in fact, it is one of the most relevant and difficult parts of the entire workflow. When the data is not good, the algorithms trained on it will not be good either.

For example, recently, I started working on developing a model in an open-science manner for the European Space Agency for fine-tuning an LLM on data concerning earth observation and earth science. The whole thing is very exciting, but where do I get the data from?

In this article, we will look at some data engineering basics for developing a so-called ETL pipeline.

I run the scripts of this article using Deepnote: a cloud-based notebook that’s great for collaborative data science projects and prototyping.

In data engineering, when we talk about pipelines, we basically talk about moving data from one place to another. In the case of training an LLM, we probably want to scrap text from various sources, such as Wikipedia, open books, datasets on hugging-face, etc. All these data, though are in different places and all have different formats, so the task starts to… Read the full blog for free on Medium.
