🚨Anthropic just showed a 30-minute workshop on how actually to use prompts for Claude. Free. No registration. No paywall. I've seen $300 courses that don't cover what they teach in the first 8 minutes. Watch it and bookmark it now.

Instead of watching Netflix tonight, dedicate two hours to this comprehensive Claude AI course. It will teach you how to build and automate virtually anything. Those who invest the time will wake up tomorrow with a valuable new skill. Watch it now and bookmark for future reference.

A great paper on context engineering in LLMs. With Bayesian context inference, AI agents can update their beliefs of the contexts such as memory, previous conversations, user domain after encountering a new query. arxiv.org/pdf/2507.13334

The search journey is not linear but dynamic, contextual and uncertain. Users can not simply be plotted along the stages of awareness, consideration, conversion & advocacy. Human behavioural models that are intellectually robust are required to make sense of the search journey

There is more to a query than surface lexical clustering and oversimplified intent classifications.

Human behavior is not linear and search intent cannot be simplified into buckets of informational, navigational, commercial amd transactional. Search intent is dynamic, has temporal dependencies and should be modelled with degree of uncertainties

Topical authority helps you understand what people are searching for and how to throughly provide coverage. Semantic authority is beneficial in understanding the "why" behind searches and catering to the temporal & dynamic nature of search intents.

There's a lot of focus on Topical Authority. A great concept but has its limitations. Here is an introduction of the concept of semantic authority. An evolution of topical authority: semanticgeek.com/insight/int…

Insight isn't just about finding answers to questions it's about generating new questions and exploring why those questions arise in the first place. That's a key benefit of being a model-driven rather than purely a dsta-driven marketer.

Decrease the time between having an idea and getting it done. Money loves speed. Poverty loves waiting.

Underrated truth… first you just do it, then you do it well.

Keyword is fundamental to a detailed search analysis. Topics are important in grouping content around themes. Concepts have a place in search and can be applied in areas such as user intent mining, content gap analysis, keyword research, search volume forecasting e.t.c #SEO

State of the world at time t: s(t) Imagined action taken at time t: a(t) Causal prediction: s(t 1) = g(s(t),a(t)) where g() is the world model. Such a *causal* world models enables planning. There are other types, e.g. retrodiction: s(t-1) = g(s(t),a(t))

New paper: On the unreasonable effectiveness of LLMs for causal inference. GPT4 achieves new SoTA on a wide range of causal tasks: graph discovery (97%, 13 pts gain), counterfactual reasoning (92%, 20 pts gain) & actual causality. How is this possible?🧵 arxiv.org/abs/2305.00050

Goodness highness! Nature has discovered causality nature.com/articles/d41586-0… We should soon expect a flood of machine learning folks asking: What is it? BTW, I didn't tell them, but the book I'm holding in the picture is the first printing (1763) of Bayes paper on Bayes Rule.

The next book after #Bookofwhy would be Primer bayes.cs.ucla.edu/PRIMER/ Individual chapters can be accessed on the web page. And, if you seek an even more formal text, with the full power and beauty of the causal revolution, see CAUSALITY bayes.cs.ucla.edu/BOOK-2K/
