Frameworks (1)

framework

Bowtie Architecture
supports
A compression-based architectural pattern in which complex, high-dimensional information passes through a low-dimensional bottleneck hub, requiring creative reinterpretation or reconstruction during decompression. The framework appears across biological signaling, neural development, evolution, and machine learning (particularly autoencoders), formalizing how systems achieve memory generalization and information efficiency through constrained information flow.
