Het tijdperk van de modelleurs is wel voorbij na dit groteske echec van het afgelopen jaar.

Pak ze hun laptopje af, sluit ze op in hun academische zolderkamertjes en laat ze nooit meer los in de maatschappij.

"Just over one year ago, the epidemiology modeling of Neil Ferguson and Imperial College played a preeminent role in shutting down most of the world."
"The exaggerated forecasts of this modeling team are now impossible to downplay or deny, and extend to almost every country on earth. Indeed, they may well constitute one of the greatest scientific failures in modern human history."

The cost associated with training large models limits the #AIresearch community's ability to innovate, because a research project often needs a lot of experimentation.
Consider training a top-performing #LanguageModel on the Billion Word benchmark. A single experiment would take 384 GPU days (6 days*64 V100 #GPUs, or as much as $36,000 using AWS on-demand instances)

1/ Shortfall analysis

In #risk a powerful concept named #shortfall analysis works very well as for building financial models for #founders and #startups.

It's a bit of a mind bender the first time you read it but has interesting applications once you understand it.
2/ Imagine an important business metric.

Let's say customers order. Link that to an equally important performance measure. Profit & Loss (PnL).

The two are clearly linked.

How would you stress test or sensitivity test them? For an internal planning meeting? For a money pitch?
3/ There are 3 models you can pick for a stress test.

a) What could be our worst case loss if PnL turns negative?

b) What is the probability of a negative PnL?

c) How much do customers orders need to drop for us to hit the red zone?

1/ I ran a course on applied financial #modeling for #credit relationship managers last week.

In the day and age of #models, do #analysts still need to understand how models are put together and numbers projected.

Credit systems give us numbers. Do we need more?
#banking #risk
2/ To translate model figures into useful insights, an analyst must understand what drives a business and how those drivers would be impacted by future outlook.

A model is only as good as the input we plug in. Without relevant insight good models also produce garbage
3/ For instance, how would remote learning impact margins at school systems? Would enrollment numbers go up or down? How about non-core expenses?

When a senior #credit committee member asks a question or challenges an assumption, you can't hide behind the #model.
