Bayesian Statistics: The three cultures

6 hour(s) ago

The article discusses different approaches to Bayesian data analysis and the decision to focus on practical aspects rather than philosophical debates in the book "Bayesian Data Analysis". It also touches on the use of Bayesian and frequentist statistics in different fields, the role of informative priors, and the limitations of probability models in accurately representing the world. The author also mentions the controversial idea of parents voting for their children and the views of Niall Ferguson and JD Vance on the topic.

### The author of the comment is discussing a model proposed by another individual that categorizes Bayesians into four groups based on their approach to using prior knowledge and their willingness to iterate on their models. The commenter disagrees with this model, particularly the idea that Bayesians do not typically iterate on their models. They argue that in their experience, iteration is seen as necessary and that priors are often uninformative due to the abundance of data. The commenter also mentions that the author, who has

Europe is in danger of regulating its tech market out of existence

5 hour(s) ago

Apple's decision to not release their new product in Europe due to strict regulatory requirements highlights the trend of tech companies choosing to exit unfavorable regulatory environments. This could lead to a "splinternet" where international tech giants may withdraw from the European market, potentially driving away innovation and access to cutting-edge technology. The EU's regulatory system is seen as arbitrary and poorly designed, and they must work towards more rational regulations to prevent companies from leaving and losing their geopolitical power.

### The EU has the power to pass laws that prevent gatekeepers and require interoperability, and Apple has the right to not comply and not offer their products in the EU. This does not mean that the EU will not have a tech market, just one without Apple products. It is seen as a victory for the EU, and since Apple is choosing to remove their products instead of following the law, they cannot complain. It is a win-win situation.

Monumental proof settles geometric Langlands conjecture

6 hour(s) ago

A team of mathematicians, led by Dennis Gaitsgory and Sam Raskin, has successfully proven the geometric Langlands conjecture, a key part of the Langlands program which connects number theory, geometry, and function fields. This monumental proof, which took 30 years to develop and spans over 800 pages, has opened up new possibilities for further research and has been compared to a "rising sea" of ideas. While challenges remain in translating the proof to other mathematical domains, researchers are optimistic about the potential impact of this breakthrough.

Top three comments:

### The commenter is excited about recent news, but points out that there are other challenges beyond just the math involved. They mention the need for a concise language to connect with modern conformal field theory, understanding the computability of models, and the human factor of convincing existing theorists to adopt this paradigm. This will require a significant effort.

Zen 5's 2-ahead branch predictor: how a 30 year old idea allows for new tricks

5 hour(s) ago

The article discusses the significance of branch prediction in modern microprocessor cores, specifically in AMD's Zen 5 architecture. The new 2-Ahead Branch Predictor Unit is a major enhancement to the core design, allowing for better performance and increased operations in the same amount of time. This method, proposed in the 1990s, has resurfaced as companies strive for higher single core performance, and AMD has successfully implemented it in their architecture. The paper "Multiple-block ahead branch predictors" by Seznec et al. explains the reasoning and implementation of this method, which involves dual-porting the instruction fetch, op cache, and Branch Target Buffer (BTB). This new predictor is a significant shift for the Zen family and will likely be
