Positioned as a paradigm shift in neural computation, Liquid Neural Networks integrate continuous-time ordinary differential equations into each neuron, enabling dynamic adaptation to incoming data streams without explicit retraining. The paper details architectural foundations such as liquid time constants, conductance-based synapses, and sparse connectivity, all contributing to efficiency and interpretability. Comparative analysis underscores LNNs’ advantages in adaptability, energy efficiency and distributed memory, alongside limitations like architectural complexity, computational overhead, and limited tooling.
