I am Pepijn van Wijk, currently doing a master's in Artificial Intelligence at the University of
Amsterdam.
Besides studying full time, I have a parttime job as a software engineer at a startup called Kexxu. At
Kexxu, I
have a number of tasks. Some notable ones from the last year have been working on the development of a
AI-powered
delta robot system, used for pick and place tasks in a factory. When not working on this project, I have
been working
on designing the architecture and implementation of a multi modal data lake for the Kexxu cloud
editor.
When I am not working or studying, I like to work on personal coding project. some projects can be found
in the section
below, however most projects can be found on my Github.
Besides programming, some of my interests include fitness, travel, history and geopolitics.
Currently, I am especially interested in learning about different DL frameworks, namely MLX, which is optimized for Apple's sillicon chips, and
tinygrad, a minimal, cross-platform DL framework. To
learn more
about these frameworks, I read papers and implementations and try to translate them to the new
framework. Some of these
projects can be found below.
Alpha-Gomoku & Connect Four puzzle apps
Writing a AlphaZero like framework to train a Gomoku- and Connect Four agent, used to find puzzles made
into two IOS apps.
MediaBuzzWords.com
Daily scraping of media headlines & using TFIDF to plot media buzz word statistics.
GeoClassiffr
Building a simple convnet to predict the country an image was taken in.
MLX optimizer collection
MLX implementation of Amsgrad and ADOPT optimizer. Also an MLX optimizer test suite.
Llama facts
Llama3.1 finetuned on 300.000 twitter facts
Llama conspiracy
Llama3.1 finetuned on a couple thousand Reddit r/conspiracy posts
MLX DeepDream
Google's DeepDream algorithm ported to Apple's mlx framework
Subber
Transcribe, translate and embed videos from different languages easily using the Apple mlx framework
PDFgpt
Chat with any PDF file using vector search, document embeddings and large language models. This project
was made a couple months before large scale releases of similar tools by e.g. OpenAI
Videotulen
A search engine built for thousands of hours of Dutch Municipality video meetings. This project was my
bachelor's thesis project.
GymVis
First ever app made. A simple webapp showing what muscle groups get activated by a large variety of
exercises
