Natural Language Autoencoders

Overview

Natural Language Autoencoders (NLAs) are encoder-decoder architectures that compress, reconstruct, and decode LLM Activations or textual representations into structured latent spaces. Operating without labeled supervision, NLAs minimize reconstruction loss to learn compact representations that preserve the semantic and mechanistic structure of underlying Transformer Circuits, enabling direct, unsupervised interpretability of model internals.

Core Mechanisms

• Unsupervised Latent Mapping: Learns compressed representations from raw activation distributions, aligning bottleneck dimensions with emergent computational features.
• Activation Decoding: Maps high-dimensional hidden states to human-readable linguistic or mechanistic explanations, revealing feature routing and causal pathways.
• Reconstruction Fidelity: Optimizes capacity constraints to balance compression ratio with information retention across attention heads, MLP layers, and residual streams.
• Interpretability Alignment: Latent factors frequently correlate with discrete syntactic constructs, semantic concepts, or task-specific computational motifs without human annotation.
