A 14-Year View of Poland’s Cybersecurity Landscape Through SOM Clustering Self-Organising Map (SOM) generated from 14 years of CERT Polska annual reports. Each dot represents a keyword extracted from the reports, and the clusters reveal how the focus of cybersecurity topics evolved over more than a decade.
1. Collecting 14 Years of CERT Polska Reports 2. Extracting Text and Cleaning the Data 3. Building a Keyword Frequency Matrix 4. Training the Self-Organising Map (SOM) 5. Visualising Each Year’s Landscape 6. Identifying Long-Term Patterns

I created a data-driven visualization that maps the development of major weapon systems from 1500 to today, revealing how global conflicts and national innovation shaped the tools of war. As the following criteria: - A timeline of weapons through history - Arcs showing technological evolution - Country based innovation patterns - Weapon performance: range vs. firepower 👆Warfare techniques OneDrive link

Methodology – Self-Organising Map (SOM) Analysis of UNESCO Defensive Sites
Key SOM parameters:
Neighbouring function: Gaussian Learning rate: 0.5 Sigma: 1.0 Training iterations: 3000 randomised updates Initialisation: Random weight initialisation with normalisation
Cluster assignment: Each site was assigned a cluster ID based on its Best Matching Unit (BMU) coordinates. Clusters were analysed for common patterns, such as historical periods, dominant criteria, or geographic concentration.
U-Matrix (Unified Distance Matrix): Shows the distances between neighbouring neurons. Light regions represent homogeneous clusters, whereas dark boundaries indicate sharp changes in site characteristics.
Hit Map: Displays how many sites map to each SOM neuron, revealing dense cluster areas and sparsely populated regions.
Component planes: Individual feature maps for each variable (e.g., century, criteria v), highlighting how attributes contribute to cluster formation.
Geographical visualisation: Cluster groups were projected onto a world map to examine spatial coherence and identify regional defensive traditions.

Youtube video showing how Bation Design ended the Middle Ages:
The Technology that Ended the Middle Ages As cannons and gunpowder weapons became stronger, high medieval walls were easily destroyed. This forced fort designs to change into low, thick, angled bastions that could absorb cannon fire and allow defenders to fire back effectively.
Image classification:
next: I will analyze and compare the proportions of buildings, roads, water, and landscape areas on a historical map (1735) versus a modern map of Gdansk to see how land use has changed over time.
Warfare techniques :
Scrape a timeline of weapons from: https://worldostats.com/timelines/evolution-of-warfare/#google_vignette
Visualise weapon evolution over time using Plotly scatter plots.
Interactive chart:
Then, I improved the chart dividing the Y axis by weapon type to get better data set and improve the outcome:
