Brainwave: A Production-Grade Model for Decoding EEG and Brain Signals

Abstract

Brainwave is a state-of-the-art neural decoder that transforms electroencephalogram (EEG) and brain signals into multimodal outputs including images, videos, and text. Built on the efficient Mamba architecture and advanced diffusion techniques, this model establishes a new paradigm for brain-computer interfaces with robust decoding capabilities.

Architecture

The model integrates several cutting-edge components:

1. Selective State Space Models (SSM) - Leverages the Mamba architecture's efficient sequence modeling capabilities for processing temporal EEG data
2. Multi-stage EEG Encoder - Specialized convolutional neural network for extracting meaningful features from raw brain signals
3. Diffusion-based Decoder - State-of-the-art diffusion probabilistic model for generating high-fidelity outputs across modalities
4. Modality-specific Generation - Optimized output generation for images, videos, and text from latent neural representations

Key Features

• Multimodal decoding: Translate brain signals into images, videos, or text with a single model
• Production-ready: Optimized for reliability, throughput, and deployment in real-world applications
• State-of-the-art performance: Achieves superior decoding accuracy compared to traditional methods
• Scalable architecture: Configurable for various deployment scenarios from edge devices to cloud infrastructure
• Extensive configuration: Customizable parameters for different EEG acquisition systems and output requirements
