Choice Modeling With Context Effects: Generalization for Observational Data Established procedures of analyzing the effect of context on choice consider simple, compact environments in laboratory settings. However, these approaches severely limit the study of context effects...

"Choice Modeling With Context Effects" is out (since Fall, I'm slow! 🐢). We apply context effects to real-world data.

Major props to Emil Mirzayev for the modeling work & Zak Babutsidze for the guidance.

A popular college major has one of the highest unemployment rates "Every kid with a laptop thinks they're the next Zuckerberg, but most can't debug their way out of a paper bag," one expert told Newsweek.

As a professor, I often get asked what major someone should choose in college. And I would always say that Computer Science was always a good choice. However, with the growth of generative AI coding recent graduates in CS have one of the highest unemployment rates.

DeepSeek R1’s bold bet on reinforcement learning: How it outpaced OpenAI at 3% of the cost DeepSeek R1’s Monday release has sent shockwaves through the AI community, disrupting assumptions about what’s required to achieve cutting-edge AI performance. This story focuses on exactly how DeepSeek managed this feat, and what it means for the vast number of users of AI models. For enterprises developing AI-driven solutions, DeepSeek’s breakthrough challenges assumptions of OpenAI's dominance -- and offers a blueprint for cost-efficient innovation.

If you want a slightly more technical description of how DeepSeek scared American AI investors, this Venture Beat article is pretty good, without being a full on academic paper.

Our need for privacy evolved from a need for physical security, which explains why we don't understand the danger of silicon valley. We don't have physical clues. Every time you are online just imagine some creepy guy in a trench coach standing right next to you.
