🚀 Usage

from aqea import AQEACompressor

# Load pre-trained compressor
compressor = AQEACompressor.from_pretrained("nextxag/aqea-wav2vec2-base-960h-29x")

# Compress embeddings
embeddings = model.encode(texts)  # 768D
compressed = compressor.compress(embeddings)  # 26D

# Decompress for retrieval
reconstructed = compressor.decompress(compressed)  # 768D

🔬 How It Works

AQEA (Adaptive Quantized Embedding Architecture) uses learned linear projections with Pre-Quantify rotation to compress embeddings while maximally preserving pairwise similarity rankings (measured by Spearman correlation).
