What is an algorithm anyway?
As per Wikipedia- http://en.wikipedia.org/wiki/Algorithm
an algorithm is a step-by-step procedure for calculations. Algorithms are used for calculation, data processing, and automated reasoning.
An algorithm is an effective method expressed as a finite list of well-defined instructions for calculating a function. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing “output” and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input
Where do I hear the word algorithm being used? Or the wat er cooler version- algols
- Pagerank – how Google calculates search results
- Public key cryptography – keeping credit card data secure
- Correcting errors (in CDs)
- Protecting passwords (cryptographic hash function)
- Perlin noise: generating landscapes in games
But Google NGrams thinks algorithms is flat in books
and Google Trends think the word is actually declining. But India remains a top user of searching for algorithms
But algorithms are increasing in ArXiv articles
and there is a bit of up and down in Algorithms Jobs
What do you think- do you hear the word too much or too little?
Cloud Computing can be evil because-
1) Most browsers are owned by for profit corporations . Corporations can be evil, sometimes
And corporations can go bankrupt. You can back up data locally, but try backing up a corporation.
2) The content on your web page can be changed using translator extensions . This has interesting ramifications as in George Orwell. You may not be even aware of subtle changes introduced in your browser in the way it renders the html or some words using keywords from a browser extension app.
Imagine a new form of language called Politically Correct Truthspeak, and that can be in English but using machine learning learn to substitute politically sensitive words with Govt sanctioned words.
3) Your DNS and IP settings can be redirected using extensions. This means if a Govt passes a law- you can be denied the websites using just the browser not even the ISP.
Thats an extreme scenario for a authoritative govt creating its own version of Mafiaafire Redirector.
So how to keep the cloud computer honest?Move some stuff to the desktop
How to keep desktop computing efficient?Use some more cloud computing
It is not an OR but an AND function in which some computing can be local, some shared and some in the cloud.
All you contest junkies, R lovers and general change the world people, here’s a new contest to use R in a business application
REVOLUTION ANALYTICS LAUNCHES “APPLICATIONS OF R IN BUSINESS” CONTEST
$20,000 in Prizes for Users Solving Business Problems with R
PALO ALTO, Calif. – September 1, 2011 – Revolution Analytics, the leading commercial provider of R software, services and support, today announced the launch of its “Applications of R in Business” contest to demonstrate real-world uses of applying R to business problems. The competition is open to all R users worldwide and submissions will be accepted through October 31. The Grand Prize winner for the best application using R or Revolution R will receive $10,000.
The bonus-prize winner for the best application using features unique to Revolution R Enterprise – such as itsbig-data analytics capabilities or its Web Services API for R – will receive $5,000. A panel of independent judges drawn from the R and business community will select the grand and bonus prize winners. Revolution Analytics will present five honorable mention prize winners each with $1,000.
“We’ve designed this contest to highlight the most interesting use cases of applying R and Revolution R to solving key business problems, such as Big Data,” said Jeff Erhardt, COO of Revolution Analytics. “The ability to process higher-volume datasets will continue to be a critical need and we encourage the submission of applications using large datasets. Our goal is to grow the collection of online materials describing how to use R for business applications so our customers can better leverage Big Analytics to meet their analytical and organizational needs.”
To enter Revolution Analytics’ “Applications of R in Business” competition (more…)
I was just checking out the stuff at http://analyticsvisualizations.appspot.com/juicekit/AnalyticsVisualization.html
Basically you login using your Google Analytics account (or actually uses the Google Analytics API) and bingo you can see the referral flow or tree for keywords to your website.
It is very very cool stuff by http://www.juiceanalytics.com/
One particular dashboard I have been thinking of is- uses Google Analytics data to not only show trends in traffic but also forecast traffic for posts using certain keywords or categories (assuming simple time series + X forecasts)
Assume I am a blogger using both Adsense and Adwords.
Suppose Adwords costs me X dollars per click, and Adsense pays me Y dollars per click.
Then a unique arbitrage opportunity would arise if
Y times CTR on my blog > X times CTR on my Ad Campaign
Is it possible. Theoretically yes? Long Tail of Internet yes.
However since there is a lag of time in which the Rates would converge , the Adsense rate would go lower or Adwords rate would go higher
Is there a tool that you can use to pump keywords with short times arbitrage opportunities , much like trading algols and quants do in finance.
Just asking !
