🕹 Technology AI Safety Models Alignment Protocol
  1. The most reasonable strategy to assess if AI models are deceptively aligned is to test their capability; incompetent models are less likely to be deceptively aligned.
  2. By using capability evaluations, models tend to fall into categories of untrusted smart models and trusted dumb models.
  3. Combining dumb trusted models with limited human oversight can help mitigate the risks posed by untrusted smart models.

🔬 Science Data science Machine Learning Wikipedia Models
  1. Wikipedia may not be the best place for beginners to learn Data Science and Machine Learning due to the unordered topics and high entry level.
  2. The concept of Likelihood function on Wikipedia made it difficult initially due to the absence of input variables, which is a crucial aspect to understand.
  3. Models in machine learning can vary from deterministic with input variables to non-deterministic like a coin flip, showing the wide range of possibilities for machine learning models.

🕹 Technology AI NLP Consciousness Computers Models
  1. There's talk about uploading human consciousness to computers soon, but it's uncertain if it's really possible. It sounds intriguing but we need to be cautious about such claims.
  2. Hope can drive media discussions, especially in tech, but it can also mislead people. It's important to balance optimism with skepticism.
  3. The idea of transferring consciousness raises many questions about identity and what it means to be human. We need to think deeply about the implications of such technology.

Peter Diamond’s Paradoxes

Something to Consider • 0 implied HN points • 30 Jul 24
💼 Business Economics Models Market Dynamics Behavioral Economics Price theory
  1. Peter Diamond shows that unrealistic economic models can help us understand real-world issues. By making certain assumptions, we can see how they lead to surprising outcomes.
  2. In his models, costs of searching for products can lead to prices behaving differently than expected. This means even in competitive markets, prices can be high if searching for the best deal is costly.
  3. Diamond’s examples suggest that different economic situations can lead to multiple levels of unemployment. People's expectations play a big role in how prices and unemployment behave in the market.

Models: some thoughts

🕹 Technology AI Models Data Innovation Trade
  1. Models are useful tools for gaining insights, but they depend heavily on the assumptions behind them. If the assumptions are wrong, the model won't be helpful.
  2. When you act on a model's predictions, you can actually change the market dynamics, which can impact the model's effectiveness.
  3. It's better to use models for exploration and creativity, rather than relying on them to make decisions for us in most cases. They can help us understand ourselves and our ideas better.

Refuting Five Myths About Large Language Models

The Future of Life • 0 implied HN points • 24 May 24
🕹 Technology AI Models Data Language Innovation
  1. Large language models (LLMs) are not just predicting the next word. They can create complex ideas and reasons, similar to how our brains work.
  2. LLMs can solve problems and generate content about new topics, even if they weren't specifically trained on them. They can understand and adapt quickly to various tasks.
  3. The development of LLM technology is still growing fast, with new discoveries happening all the time. This means we can expect even more advancements in artificial intelligence in the future.

LangSmith Hub By The Numbers

🕹 Technology AI NLP Chatbots Data Models
  1. LangSmith has four main parts: Projects, Data, Testing, and Hub. The first three are all about improving production, while Hub is for testing before launch.
  2. Chatbots are the most popular use case for using large language models, followed closely by summarization and questions and answers on documents.
  3. OpenAI leads the prompt count in the LangSmith Hub, followed by Anthropic and Google. This shows how important different models are when experimenting with prompts.

Alternatives to the CAPM: Part 4: Market-Implied cost of equity

💰 Finance Equity Investment Valuation Risk Models Investing Valuation Equity Risk management Market Theory
  1. You can calculate the market-implied cost of equity using a simple dividend discount model, which helps you understand if a stock is fairly priced. This method allows you to figure out the expected return on a stock based on its price and future dividends.
  2. Comparing the market-implied cost of equity to a conventional one can help you decide whether to invest in a stock. If the market-implied cost is much higher than your estimate, it might mean the stock is riskier or less attractive.
  3. You can use the market-implied cost of equity for an entire sector so that you have a uniform measure for evaluating companies in that sector. This approach can make it easier to compare different companies without getting lost in individual risks.

  1. Warren Buffett believes the Black-Scholes model gives bad values for long-term options, which is a viewpoint that some disagree with.
  2. Buffett's opinions on option valuation may not consider newer methods that adjust the Black-Scholes model for better accuracy.
  3. You can still be a successful investor without knowing how to value options, as long as you avoid investments that rely heavily on them.

A critique of successor representations as a model of learning in the hippocampus

Artificial General Ideas • 0 implied HN points • 14 Sep 24
🔬 Science Neuroscience Psychology Cognition Learning Models
  1. Successor representations (SR) does not explain how place cells in the hippocampus learn or form. It assumes inputs that are already perfect place fields, so it can't help in understanding their development.
  2. Many claims about SR's abilities, like making predictions or forming hierarchies, actually relate to simpler models like Markov chains. SR doesn't add much value to those features.
  3. Experiments often used to support SR in humans might actually show evidence for more general planning methods. Model-based reasoning seems to fit the observed behavior better than SR does.
