Part 3 illustrates the variability of results that can occur when repeatedly unmixing the same data set, and presents approaches to addressing the resultant uncertainty.

Part 2 of this series on unmixing is now available:

https://dblog.vitumbre.tech/dart/unmixing-using-nmf-part-2-evaluating-the-number-of-end-members/

Part 2 addresses the challenge of deciding how many end members are in a data set, recommends algorithms for Python, Julia, and R, and illustrates how several factors affect that determination.

I just posted part 1 of a 3-part series on unmixing of data sets using non-negative matrix factorization.

https://dblog.vitumbre.tech/dart/unmixing-using-non-negative-matrix-factorization-nmf-part-1-introduction-and-implementation/

Part 1 contains implementations in Python, Julia, and R, and includes an assessment of the relative accuracy of these implementations.

Parts 2 and 3 will follow shortly, and will contain more detail on the identification of, and accurate characterization of, unmixing end members.

The mapdata.py data explorer now has two new ways of summarizing missing data. It can also now create a Zipf's Law plot for any categorical variable. Install, update, or download it from PyPI: https://pypi.org/project/mapdata/

🔍 Exploring groundwater chemistry — from ions to equilibrium

This ternary diagram shows how groundwater samples affected by mine water vary in anion composition. Each point represents one sample, colored by its calcite saturation index (SI) from PHREEQC calculations.

Such early-stage exploration helps reveal subtle geochemical trends — where equilibrium breaks down, reactions intensify, and contamination fronts begin to form.

I'm continuing to play with my music listening data, and i suspect that spotify (2017-2021) and plex (2022+) handle time zones differently and that I'm not properly accounting for that difference.

New features in the data explorer MapData.py (https://pypi.org/project/mapdata/):

1. Saturation, contrast, and brightness of basemap images can be customized.

2. Hovering over a point on a scatter plot will display the label for that point.

3. Data can be recoded to edit the values in an existing column or to add a column with new values to the data table.

When a spatial data set contains multiple values at a location (e.g., from different dates or depths/elevations), the number of data points at a location, and even the presence of multiple data points at a location, may not be apparent on a 2-D map. The latest version of MapData.py (https://pypi.org/project/mapdata/) addresses this situation in five ways:

I ran into issues with @geopandas explore today when the #geodataframe included datetime columns. Still have to check if this is a known issue and then create a reproducible example

#opensource #gischat #dataexploration #visualization

say one had a #database of books with 50k records in it. What would you use to explore / manipulate it?

Thinking more along the lines of a GUI rather than pandas, etc.

Extra points if it can take snapshots of the db on command and one can easily compare/merge (think git diffs) the snapshots.
