They Did It - Meta Just Announced an AI That Reads Thoughts—The World Will Never Be the Same!
AI Summary
Summary of AI Technology for Translating Brain Scans into Text
- Breakthrough in AI: Meta has announced an AI that can translate brain activity into text, offering new possibilities for individuals with neurological conditions.
- Non-Invasive Technology: Meta’s approach is non-invasive, using brain activity to understand sentence formation without surgery.
- Brain to Text System: The system, called Brain2Qwerty, decodes sentences from brain activity while participants type memorized sentences on a QWERTY keyboard.
- Study Details:
- Conducted with 35 healthy volunteers.
- Utilizes electroencephalography (EEG) and magnetoencephalography (MEG).
- Demonstrated a character error rate (CER) of 32% with MEG, superior to EEG’s 67%.
- The best instances of the model reduced CER to 19%.
- Generalization Capability: The AI can decode sentences not included in the training data, indicating a broader understanding of language.
- Collaborative Research: Meta collaborated with international researchers for two significant studies on AI’s ability to interpret brain signals and understand reasoning in language production.
- Research Components:
- Image encoder: Creates visual frameworks.
- Brain encoder: Correlates MEG signals with image representations.
- Image decoder: Translates processed brain signals into images.
- Accuracy and Implications:
- AI model decodes approximately 80% of characters with MEG.
- Could lead to non-invasive brain-computer interfaces, enhancing communication for those unable to speak.
- Challenges and Solutions:
- Decoding accuracy needs improvement.
- Patients must remain still in magnetically shielded rooms.
- MEG machines are large and expensive.
- Meta is working on more practical brain imaging methods and improving AI models for signal interpretation.
- Broader Research Goals: Meta aims to explore cognitive processes for applications in healthcare, education, and human-computer interaction.
- Competition from Neuralink:
- Neuralink is developing a surgically implanted brain chip to help disabled individuals control digital devices with their thoughts.
- Clinical trials are underway, with a patient already using the device to play video games and create 3D objects.
