Bridging the Gap: How AI Translates Sign Language into Speech

Exploring how AI-powered models transform sign language into natural-sounding spoken words At Cmotions, we enjoy leveraging AI to solve business or societal challenges. One of the challenges we set out to address is communication accessibility for individuals who rely on sign language. What if AI could bridge the gap between sign language and spoken language, making […]

Fine-Tuning a Video Classification Model for Hand Sign Recognition in Python

Data Science is an ever-evolving field, and we at Cmotions are always ready to evolve with it. Each year, we select a project that pushes our boundaries—preferably by exploring a new skill, addressing a relevant societal issue, and simply engaging in a fun team challenge. This year, we set out to tackle AI video models, […]

Princess Peach rescued from the claws of Bowser at our Super Mario Hackathon

At 21 april 2023, we held an epic hackathon where 10 teams from KPN, Rabobank, DPG, Athora, ANWB, UWV, Lifetri, and Eneco joined forces to rescue our beloved Princess Peach from the claws of Bowser. It was a fierce battle, but in the end, only one team emerged victorious. And who was that, you may […]

Let’s get balanced! A simple guide on how to deal with class imbalance in your binary data

At Cmotions we’ve always had a lot of discussion amongst colleagues whether or not to balance our datasets when building a predictive model. Everyone has their own personal preference and way of working, but which approach is “the best”? We simply didn’t know until we stumbled upon this paper written by Jacques Wainer and Rodrigo […]

Reinforcement Learning in Python to play Snake

Use Reinforcement Learning to teach the computer to play Snake

At Cmotions we love to learn from each other and that is why we regularly collaborate on internal projects, in which we can express our creativity, curiosity and eagerness to learn. In this article we want to share what we did in the ‘Snake’ project, where we learned the computer to play snake using Reinforcement […]
