This is a recording of a local application run. It illustrates individual predictions and network activity; it is not a benchmark of overall model accuracy. https://zongo-is.me/media/neural-network/forward-pass.mp4 2026-10-01T13:52:59+02:00 https://zongo-is.me/watch/word-embedding-explorer/ Word arithmetic, neighborhoods and semantic paths https://zongo-is.me/media/word-embeddings/capabilities.webp A tour of three word-embedding tools: king minus man plus woman, a semantic neighborhood around greek, and a path from computer to internet. Edited from my application demonstrations. The spatial display is a projection; semantic similarity is computed in the original embedding space. https://zongo-is.me/media/word-embeddings/capabilities.mp4 2026-10-01T13:52:59+02:00 https://zongo-is.me/watch/dijkstra-pathfinding/ Dijkstra’s algorithm in a 3D world https://zongo-is.me/media/pathfinding.webp Follow a Dijkstra traversal through buildings and trees in a 3D pathfinding visualizer, from the search frontier to the recovered route. Recorded from the current application and played at 2.5× speed. This deterministic graph-search demonstration is separate from the learning replay. https://zongo-is.me/media/pathfinding.mp4 2026-10-01T11:21:42+02:00 https://zongo-is.me/watch/q-learning-pathfinding/ A learning agent: early failure to later routes https://zongo-is.me/media/pathfinding-learning.webp Compare episodes 1, 503 and 998 from an actual 1,000-episode learning run with seven clustered sink obstacles. An instrumented replay of the original application’s learning rule. It uses a scalar value table and is not a conventional state–action Q-table. The Field Note documents that distinction and the capture repairs. https://zongo-is.me/media/pathfinding-learning.mp4 2026-10-01T22:30:22+02:00 https://zongo-is.me/watch/java-waterflow/ Water moving across Java Swing terrain https://zongo-is.me/media/waterflow.webp See water propagate across grayscale terrain in a Java Swing simulation built around shared state, worker threads and layered rendering. A capture of the original renderer with isolated boundary and thread-visibility repairs. The project notes explain the shared-state limitations; this is not a fluid-dynamics benchmark. https://zongo-is.me/media/waterflow.mp4 2026-10-01T11:21:42+02:00 https://zongo-is.me/watch/cpp-image-segmentation/ C++ image segmentation across thresholds https://zongo-is.me/media/connected-components/films/portrait.webp Compare a grayscale portrait with actual C++ segmentation outputs as the threshold rises from 32 to 224. The input photograph is AI-generated. The segmentation images are actual C++ outputs. The project page includes more realistic specimens and a display-inversion control. https://zongo-is.me/media/connected-components/films/portrait.mp4 2026-10-01T13:52:59+02:00 https://zongo-is.me/watch/kmeans-double-helix/ K-means on a 3D double helix https://zongo-is.me/media/clustering.jpg Watch K-means partition a double helix in an interactive clustering laboratory with a spatial scene and live diagnostics. A recording of the original application. This film shows K-means; the live laboratory also includes Gaussian mixtures, DBSCAN and spectral clustering. https://zongo-is.me/media/clustering.mp4 2026-10-01T11:21:42+02:00 https://zongo-is.me/watch/java-udp-chat/ Direct and group messages over UDP https://zongo-is.me/media/udp-messenger/local-delivery.webp Two Java Swing clients exchange direct replies and a group message through a locally running UDP server. Recorded from actual Swing applications with verified local UDP delivery. The recording does not imply guaranteed packet delivery or encrypted transport. https://zongo-is.me/media/udp-messenger/local-delivery.mp4 2026-10-01T13:52:59+02:00 https://zongo-is.me/watch/python-grid-world/ A Python grid-world learning history https://zongo-is.me/media/q-learning.jpg Watch a recorded state history from a Python Q-learning grid-world experiment with rewards and obstacles. A historical repository animation shortened for playback. The associated Field Note distinguishes Q-learning from the separate value-iteration experiment. https://zongo-is.me/media/q-learning.mp4 2026-10-01T12:07:36+02:00 https://zongo-is.me/watch/semantic-word-path/ A semantic path from computer to internet https://zongo-is.me/media/word-embeddings/semantic-path.webp Follow computer → computers → software → ip → internet in the word-embedding explorer. Edited from my application demo recording. This is a route through word-vector relationships, not a claim that the words form a unique linguistic definition. https://zongo-is.me/media/word-embeddings/semantic-path.mp4 2026-10-01T13:52:59+02:00
