Resource Constraints in Brain Models
- Biologically plausible brain models embrace limited resources, unlike artificial neural networks.
- This constraint leads to innovative solutions like Legendre Memory Units (LMUs) for efficient information encoding.
Continuous Processing in the Brain
- Brains operate in continuous time and state, unlike discretized artificial networks.
- Legendre Memory Units (LMUs) leverage continuity for optimal time series processing, outperforming LSTMs and transformers.
Benefits of Continuous Representation
- Continuous representation avoids premature assumptions about time resolution.
- It allows networks to discover optimal resolutions, unlike fixed time steps in discrete models.
