#clustering — Public Fediverse posts

@junesim63
Having been a bit-part player in the #SiliconRoundabout ambition myself, I can say that it was about #digital #entrepreneurs and #startups, #innovation, shared #workspaces and the benefits of multiple companies #clustering in an area rich with #coffee shops, #culture and food.
It was emphatically not about bulldozing communities to build power-hungry, inhuman industrial monoliths with no connection to their surroundings or to the economic prosperity of the #community.

Don’t use Silicon Roundabout as an excuse for this vandalism.

Ah, the pinnacle of #AI #advancement is upon us: GPT-5.5, now with 50% more #token #clustering confusion 🧩🤖. Apparently, this latest marvel of technology can't tell its reasoning tokens from a hole in the ground, leading to the groundbreaking discovery that more gibberish ≠ better performance. Kudos to #GitHub for hosting the digital equivalent of a toddler trying to assemble a nuclear reactor ⚛️👶.

Data-driven empathy is the future of UX. Moving beyond the limitations of subjective persona creation, we now utilize clustering algorithms to uncover latent user patterns. This methodological shift ensures design decisions are rooted in empirical evidence rather than intuition. This guide at WebHeads United explores the technical frameworks for this synthesis. Refine your audience insights with algorithmic rigour.

GaMAC: Открытая библиотека для автоматической кластеризации мультимодальных данных под GPU

На сегодняшний день не существует полноценного инструментария для кластеризации на графическом процессоре, что стало основным стимулом для создания универсальной библиотеки, способной автоматически решать задачи кластеризации данных различных представлений. Мы представляем GaMAC - библиотека автоматической оптимизации кластеризации с поддержкой с GPU.

Behind the scenes of “beautiful scientific graphics”

If you think that clean, elegant visuals in scientific reports are produced in a couple of clicks — I’m here to disappoint you. 🙂

Here’s one of many failed attempts to visualize results based on thermodynamic modeling of geochemical processes.

Turning raw multidimensional data into something that a human reader can intuitively grasp is a separate challenge — with dozens of input parameters and only a few truly useful outcomes.

Good science is not only about computation, but also about communication.

🚀 TopicWatchdog – Week 3: Stable Topics with BERTopic

KMeans worked, but cluster IDs kept jumping across retrains. This week I added a Python BERTopic stage with a BigQuery registry → stable topic IDs!

🟢 UMAP + HDBSCAN
🟢 Stable IDs via registry
🟢 Auto-labels with Gemini
🟢 Looker Studio dashboards

📊 3,802 topics → 2,472 mapped, top clusters: migration, economy, climate, politics.

Summer ☀️ read: a new paper on model-based clustering just appeared in Computo!

Julien Jacques and Brendan Thomas Murphy publish a new method for clustering multivariate count data. The method combines feature selection and clustering, and is based on conditionally independent Poisson mixture models and Poisson generalized linear models.

On simulations, the Adjusted Rand Index (ARI) of the model with selected variables is close to the optimal ARI obtained with the true clustering variables.

The paper and accompanying R code are available at https://computo-journal.org/published-202507-jacques-count-data/

Don't pass by the new insightful lecture from Dr. Alejandro Rodriguez Garcia, Abdus Salam International Centre for Theoretical Physics (ICTP)!

In this one, Alex provides a comprehensive overview of various clustering methods, including flat, fuzzy, and hierarchical approaches. His lecture not only discusses the mathematical foundations of techniques like k-means and k-medoids but also highlights their practical applications across fields such as image recognition and data classification.

This lecture is an excellent opportunity to deepen your understanding of unsupervised learning and engage critically with advanced clustering methods.

#30DayChartChallenge Día 14: Kinship! 🌿 Hoy toca visualizar "parentescos" animales, pero basados en ¡similitud de rasgos! #RelationshipsWeek #Animals

Este dendrograma horizontal es el resultado de un clustering jerárquico (hclust Ward.D2) sobre ~170 especies, usando su Masa Corporal y Longevidad Máxima (log-transformadas y escaladas). ¡Muestra quién se agrupa con quién según su estrategia de vida!

Las ramas unen las especies más similares. La longitud horizontal hasta la unión indica cuán diferentes son. Se ven grandes grupos que separan, por ejemplo, animales muy grandes/longevos de otros más pequeños/rápidos. Es una forma de ver la estructura oculta en los datos de rasgos.

(Solo se muestra 1/3 de las etiquetas para no saturar!)
