The anti-Bayesian is standing at the back window with a shotgun, scanning for priors coming over the hill, while a million assumptions just walk right into his house through the front door. (also, an interesting point by Yann LeCun in 2012 about human language)

Summary

An editorial analyst highlights a 2012 blog post discussing Bayesian statistics and an exchange with computer scientist Yann LeCun regarding human language acquisition. The original post suggested that the brain's pre-existing structure for human language acts as prior information, enabling decoding. LeCun countered that human language evolved to be easily decodable by the human brain, rather than the brain being pre-tuned for specific languages. He also argued that language is not an exceptionally complicated task, noting its relatively short evolutionary history (around 300,000 years) and the small brain region it occupies, contrasting it with vision, which he considers far more complex due to its hundreds of millions of years of evolution and extensive brain allocation.

Key takeaway

For cognitive scientists and AI researchers modeling human intelligence, consider LeCun's perspective that language's "simplicity" stems from co-evolution with the brain. This challenges assumptions about language as a uniquely complex task and suggests focusing on vision's profound complexity for deeper insights into advanced neural processing. Your research might benefit from re-evaluating the relative difficulty of these cognitive domains.

Key insights

Human language evolved for brain decodability, and vision is a more complex cognitive task than language.
