Only One Thing is needed.

The #1 skill for anyone doing anything.

I believe the most important skill, for anyone, is the quick intuitive assessment of the significance of things: how big the issue is, what the scale of the problem, what’s the scope of impact of it, the strategic significance of it.

It is this assessment that drive the next move: the level of attention and the amount of resource allocated to it; and without the right level of attention and the right amount of resource allocated to it, you can hardly get treat it with the right strategy.

The more complex the decision context is, the less rountine and predictable the incoming situation is, the more important this skill is. When facing this situation, the best strategy is to put your frontline with people with the best above skill. This is hard to do since those people also tend to be the most skilled in doing many things as well.

One justification of it comes from the optimal allocation of attention/resources in decision theory; which says that your first meta-decision before any decision is the decision for how much attention/resources you are going to allocate for RESEARCHING the issue. And normally, it is based on your skill #1.

This skill is difficult to cultivate.

Rakesh’s Data Mining Definition

An Expansive Definition of Data Mining (Rekesh Agrawal, KDD06):
Deriving value from a data collection by studying and understanding the structure of the constituent data.

This is the closest in meaning to what I have in mind for “Datarology”. I particular like the part of the definition where he used “understanding …” instead of “analyzing …”, because I believe Synthesizing is an equally important activity for Datarology as analyzing.

On Bullshit

Filed under: Business, Random Thoughts, reading — Tags: — Huayin Wang @ 3:55 pm

I read On Bullshit by Harry Frankfurt some time ago. It was a Sunday afternoon, at a Borders bookstore, and I was attracted to it by the very first sentence of it:

“One of the most salient features of our culture is that there is so much bulklshit.”

The second sentence is “Everyone know this.”

The book then tours me with its interesting mix of academic and satire style prose. The apparent seriousness has an undertone of absurdism.

A few pages from the back:

“Bullshit is unavoidable whenever circumstances require someone to talk without knowing what he is talking about. Thus the production of bullshit is stimulated whenever a person’s obligations or opportunities to speak about some topic are more excessive than his knowledge of the facts that are relevant to that topic. This discrepancy is common in public life, where people are frequently impelled — whether by their own propensities or by the demands of others — to speak extensively about matters of which they are to some degree ignorant. Closely related instances arise from the widespread conviction that it is the responsibility of a citizen in a democracy to have opinions about everything, or at least everything that pertains to the conduct of his country’s affairs. The lack of any significant connection between a person’s opinions and his apprehension of reality will be even more severe, needless to say, for someone who believes it his responsibility, as a conscientious moral agent, to evaluate events and conditions in all parts of the world.”

“The contemporary proliferation of bullshit also has deeper sources, in various forms of skepticism which deny that we can have any reliable access to an objective reality and which therefore reject the possibility of knowing how things truly are. These “anti-realist” doctrines undermine confidence in the value of disinterested efforts to determine what is true and what is false, and even in the intelligibility of the notion of objective inquiry. One response to this loss of confidence has been a retreat from the discipline required by dedication to the ideal of correctness to a quite different sort of discipline, which is imposed by pursuit of an alternative ideal of sincerity. Rather than seeking primarily to arrive at accurate representations of a common world, the individual turns toward trying to provide honest representations of himself. Convinced that reality has no inherent nature, which he might hope to identify as the truth about things, he devotes himself to being true to his own nature. It is as though he decides that since it makes no sense to try to be true to the facts, he must therefore try instead to be true to himself.”

So what’s the philosophical arguement he made in the book? Ask and you lost it.

books are too thick these days

Filed under: misc, Random Thoughts, reading — Tags: — Huayin Wang @ 1:53 pm

hint:

– Dao De Jing has about 5000 words

– (granted, there is bible, but there is only one bible )
other evidence?

– what % of books are never finished reading? and
– what % of people still reading books these days?

– what % of people reading books for the sake of writing books?

reasons?

– unconscious writers’ compulsive monologing syndrome
– trapped in the language maze

– feeding the appetize of auto-pilot readers

Great action

great actions are rare.  When closely witnessed, a great action is found to consist of numerous nimble actions each with graceful precision.

No free lunch theorem

Filed under: business strategy, Datarology, Random Thoughts, Uncategorized — Tags: , — Huayin Wang @ 2:06 pm

There are many forms of NFL theorem. I particularly like the one when applied to optimization/search algorithm. In one version, it can be stated as ” all algorithms that search for an extremum of a cost function perform exactly the same, when averaged over all possible cost functions. In particular, if algorithm A outperforms algorithm B on some cost functions, then loosely speaking there must exist exactly as many other functions where B outperforms A.” [Wolpert and Macready (1995)], see also No Free Lunch Theorem

It is a humbling experience when meditating on it, to be reminded of the importance of contextual knowledge of the problem.
