Introduction
In a world where mobile typing has become essential, FUTO Swipe stands out as an innovative swipe typing model. Designed to offer speed and accuracy, it is integrated into the FUTO Keyboard app, which operates entirely offline. Unlike many keyboards that compromise user privacy, FUTO Swipe offers an open-source alternative, making this technology accessible while respecting personal data.
Why FUTO Swipe?
Swipe typing has become popular due to its ability to accelerate communication. However, many existing solutions rely on apps that collect personal data or use unlicensed private libraries. FUTO Swipe was developed to fill this gap by providing an open-source model, allowing users and developers to adopt it without compromising privacy.
The Models Behind FUTO Swipe
FUTO Swipe's architecture relies on three key models:
- The Encoder Model: Universal and layout-agnostic, it offers general predictions for swipe typing. While not the most accurate, it forms the backbone of the system.
- The ContextLM Model: A small language model, trained for a single language, that enhances prediction quality by eliminating improbable words in the given context.
- The Decoder Model: Language and layout-specific, it learns layout peculiarities to offer cutting-edge accuracy.
With these three models and a beam width of 300, FUTO Swipe achieves an error rate of just 4% on its test set, with an error rate below 1% ignoring out-of-vocabulary cases.
A Lightweight and Efficient Model
The encoder model counts only 635,140 parameters, with the decoder adding 304,155 more. The heaviest model, ContextLM, reaches 1.5 million parameters, but 1.1 million of these are embeddings. This allows FUTO Swipe to maintain a minimal footprint, enabling the app to run efficiently even on devices with limited resources.
Open Source Dataset
FUTO Swipe was trained on a dataset of 1 million swipe gestures, available under the MIT license on HuggingFace. This open-source approach invites contributors to continuously improve the model, ensuring scalable and collaborative technology.
Industry Impact and Future Prospects
With its accessible and privacy-respecting technology, FUTO Swipe could redefine the standards of mobile typing. By enabling developers to create innovative applications without compromising user confidentiality, FUTO Swipe lays the foundation for a new era in swipe typing technology.
Conclusion
FUTO Swipe is not just a swipe typing model; it's a new way of thinking about mobile typing, centered on the user. With its compact models and open-source approach, it offers a high-performance and respectful solution. Let's discuss your project in 15 minutes.
