“More than 60% of dogs assessed do not meet the testing requirements,” ... but if the ones who do meet the standards are bringing in $1.8 million a year then maybe you should lower the standards?

Or maybe ... this is a superstar economy, the top dogs are bringing in $20 million a year, and the marginal dog is barely breaking even after deducting the handler’s salary and the cost of kibble. ... I guess they can’t really quit to go work for Zimbabwe.

The Oxford Research Encyclopedia of Economics & Finance has just published my article on explainability and interpretability in AI & ML:

Those of you in Tokyo may have seen me present versions of this.

Comments very welcome!

<MattLevine> This is pretty stupid, but on the other hand I bet there will be an absolutely straight-faced launch of a prediction markets index in like two weeks. I really like the idea of television commentators saying “prediction markets were up today.” </MattLevine>

what parameter values generate Figure 1 in Nordhaus' 1992 (Lethal Model 2)?

Figure 1 in Nordhaus (1992) depends on $\theta_1, \theta_2, \xi_0, \xi_1$ and initial values $Y_0$ and $L_0$. It displays the values used for $\theta_1$ and $\theta_2$, but not the others. I have...

#60minutes was responsible for one of the most important political interviews of my life, when #LesleyStahl asked US Secretary of State Madeleine Albright about estimates that the US #sanctions on #Iraq had contributed to a half million extra deaths of children under five years old. Albright replied, "we think the price is worth it".

Offer AgentGPT as a premium service, charging more - it makes the (random) shufle trades for them automatically, generating `--verbose` logs for .md file@ 'execution' rather than TradeGPT's 'advisory'. Add dashboards, analytics, bells, whistles to both.
TradeGPT pitch deck: sign up customers, offering free LLM credits to support trades. Ask them what their risk/return preferences are. Use their funds to buy inexpensive market trackers. Randomly propose shuffles of market portfolio around between their accounts: no actual trades, to save the TCs. If they sell out of a rise, cheap LLM tells take profit story; when out of a fall, a stop loss story. Give them the vol they want, stories galore, cheap GPT calls, and 1% less than the market return.
