Shame on you, Saina:
Cocking a snook at the Badminton Association of India, a defiant Saina Nehwal chose to withdraw when holding two match-points against Russian Ksenia Polikarpova in the first round of the $120,000 Syed Modi Grand Prix Gold badminton championship here.
The World No. 3 cited a knee-injury that had troubled her from this year’s Denmark Open as the reason for her decision to withdraw when leading 21-17, 20-18 against a rival ranked 165th.
“With many important tournaments lined up next month, I decided not to aggravate the injury,” said a smiling Saina after she waved to the disappointed crowd for cheering her all the way in the 29-minute encounter.
and
“Throughout the year, the BAI does everything that Saina wants. Government allows Saina economy class (airfare) but BAI helps her travel First Class by paying the difference in fare. In return, BAI wants her to play in a couple of events in the country. But that is not happening,” said a senior BAI official on condition of anonymity.
and
By the end of the day, a ‘chastened’ BAI must have realised that it is better to accept a firm ‘no’ than a reluctant ‘yes’ from Saina. As one of the BAI official put it, “Sadly, the truth is, the Indian badminton needs Saina Nehwal more than Saina needing Indian badminton.” 
Methinks somebody's shoes are getting too small for them. To be fair, it could be advice from questionable sources that is causing this kind of behaviour.

It may be possible to test whether we're living in a simulation.

An earlier article that says there may be a 20% chance that we do.

Via Rigorous Intuition, a mind-blowing argument.

Let's see:
  1. This explains the Big Bang. Things started when the simulator program was kicked off.
  2. Things are discrete in the quantum world because the simulation is, by nature, discrete -- whether it's event-driven or time-stepped.
  3. Non-local connections are explained as well -- the 'master controller' is the CPU running the simulation, and it has access to (and is able to maintain) all the simulation objects and their dependencies, irrespective of where they are in the simulated world.
  4. The usual paradoxes like wave-particle duality, the uncertainty principle, and so on are explained by the analogy of mathematical formulas and 'lazy initialization'.
  5. Karma and synchronicity? Global state/memory/logic in the simulator program.
  6. God is the entity running the simulation.
Of course, this still doesn't explain things like ultimate cause (is our God also a simulated entity? How many levels does this go?).

Awfully decent of the Chinese, preferring to pay for stuff rather than pillaging and plundering the to-be-annexed Indian territory:
In 1962, for example, Deak warned the CIA that China was planning to invade India after his company’s Hong Kong branch was swamped with Chinese orders for Indian rupees intended for advance soldiers.

Sachin Tendulkar:
When I feel it is time, I will take a call. It is going to be a tough call nevertheless. It is going to be tough because this is what I have been doing all my life. It is going to be difficult to suddenly hang up my boots one day.
I have the highest regard for Tendulkar, but somebody please give the man a copy of Who Moved My Cheese?

Reason #1876 why I'm glad I didn't take the civil services exam -- questions like this:
Domestic resource mobilisation, though central to the process of Indian economic growth, is characterized by several constraints. Explain in ten words.
I made up the "ten words" bit, but I think I would have shown myself the door because my ten words would have been roughly divided as below:
  • Babus
  • Netas
  • Corruption
  • Nexus
  • Six words unprintable in a family blog

One little-noticed wrinkle in the recent failed no-confidence motion is that it serves as 'inoculation': no other such motions can be brought up against the government for the next six months. Watch out for attempts to push through more audacious policies/legislation, without any worries about the government falling because of such attempts.

Even when victorious, let there be no joy,
    For such joy leads to contentment with slaughter.
Those who are content with slaughter
    Cannot find fulfillment in the world.
-- Tao Te Ching

Something entirely lost on these joyous folks. Contrast this with the reaction of Major Unnikrishnan's father.

I think I've said this before, but will say it again: the best way to decide whether somebody gets the death penalty is the Arab/Shariah custom of putting the question to the victim's family. Needless to say, this is not a pardon, but only to decide whether the murderer is put to death or spends the rest of his life (life; not 14 years commuted to 10 on account of Gandhi Jayanti, good conduct, and so on) in prison.

Yeah, that about sums it up:
Let's clear this up again. The ECB is going to buy bonds of bankrupt banks just so that the banks can buy more bonds from bankrupt governments. Meanwhile, just to prop this up the ESM will borrow money from bankrupt governments to buy the very bonds of those bankrupt governments.
Another interesting tidbit from the report: the demographics are so bad in Japan that they actually have adult diaper fashion shows.

[H]aving the career of the beloved CIA Director and the commanding general in Afghanistan instantly destroyed due to highly invasive and unwarranted electronic surveillance is almost enough to make one believe not only that there is a god, but that he is an ardent civil libertarian.

Predicting the English Premier League - Part 3

Having just completed the machine learning course in Coursera, time to put the knowledge to good use. Neural networks seem to be the most promising among the classification algorithms (logistic regression and SVMs being the others covered in the course) -- I did do bit of mucking around with logistic regression, but the results were singularly disappointing.

Since we're dealing with neural networks, no need to be picky with what features to use; in addition to the ten parameters considered the last time, let's throw in as many additional ones that we can think of, and let the algorithm sort it out. Here are the features forming the input layer (the features are normalized -- something I didn't do the last time):
  1. Home record of home team
  2. Away record of away team
  3. Record of home team
  4. Record of away team
  5. Record of home team in last three games
  6. Record of away team in last three games
  7. Record of home team in last five games
  8. Record of away team in last five games
  9. Record of home team in last seven games
  10. Record of away team in last seven games
  11. Record of home team in last three home games
  12. Record of away team in last three away games
  13. Record of home team in last five home games
  14. Record of away team in last five away games
  15. Record of home team in last seven home games
  16. Record of away team in last seven away games
  17. Total goals scored by home team
  18. Total goals scored against home team
  19. Total goals scored by away team
  20. Total goals scored against away team
  21. Position of home team in points table
  22. Position of away team in points table
We use one hidden layer with five activation units -- could've used more hidden layers, but the code I wrote for the course assignments is for a single hidden layer, and I'm too lazy to bother to make the code more general. Not to mention that the efficacy of using more layers is moot.

The examples are a total of 560 matches from the 2010-11 and 2011-12 seasons (we ignore the first few weeks of each season to a) get things to settle down and b) avoid division-by-zero errors for some of the features (e.g. when we're considering the first match a team plays in the season).

350 matches are used as the training set and 30%, i.e. 105, from the remainder form the cross validation set.

After a lot of number crunching, the results are not too good, at least not yet. It looks like I'll be needing more data (as indicated by the results from the learning curve plots). A lambda value of 0.16 or 0.32 seems to be the most promising.


The next step is to get the results for the 2009-10 season -- and earlier if required. More grunt work. Stay tuned.

Update: Well, I went all out and got the results for three seasons -- 2007-08, 2008-09 and 2009-10 -- but no cigar; the prediction accuracy refuses to go above ~50%, whatever values of lambda and feature list I consider (I added two more features to the above list: total games played so far by both teams). It might be possible to squeeze out a bit more by running a genetic algorithm and figuring out the best lambda value and features, but I don't think the effort is worth it. Question: what is the minimal prediction accuracy required to get a 20% return on bets over the long-term, e.g., over an entire season?

Imagine a slightly larger-than-life statue of a naked boy-man wearing only the remnants of a pair of jeans and a hat that looks like a flak helmet, his foot resting on the severed, blood-dripping head of a Roman legionary.

Oh wait, you don't have imagine it. Here's an actual picture:


Picture courtesy of the Rock Garden, Malampuzha, Kerala. I'm too lazy to google for it, but I bet there is a back story involving a twisted and diseased mind that spawned the whole house of horrors (the above picture is only a sample; there's a lot more cringe-inducing crap in my vacation pictures folder).

Comment of the decade (on Business Insider's 1068th Marissa Mayer story):

Is Farrukh Dhondy aware of Nafeez Ahmed's post about Abu Hamza's links with MI6? The sad part is that the visibility such an op-ed column gets is orders of magnitude greater than what Nafeez Ahmed's writing does.

The Hindu on allowing FDI in retail:
Even within the retail trade, the government’s claim that FDI is good for the nation is difficult to defend. The success of large retail cannot be based only on the expansion of the retail space, but requires acquiring a share of the existing space occupied by small retailers. NSSO data for 2009-10 indicate that the occupational category consisting largely of the wholesale and retail trade employed 44 million Indians. The displacement of a substantial number of these workers is inevitable. Since the economies of scale and scope that size delivers in organised retailing are expected to reduce costs by raising labour productivity, the expansion of large retail will not compensate for this employment loss.
Which reminds me of this comment by 'StarmanSkye' at RI:
 I guess the New Politics of neo-Conservative values which we see in the unprecedented official government protection that encourages the power & privilege of the financial criminal class suggests a kind of logical argument can be made that the trend from "Its the duty of every American industry, company, corporation, business person and citizen to maximize their profits by any *legal* means allowed, including evading, deflecting, eliminating or deferring their tax liability" leads to:
"Its the duty of every worker to inhibit productivity by any and all means *legally* allowed so as to stimulate maximal employment of the work force".
Game, set and match.

Rotten meat? More like local traders being undercut by low-cost 'imports' from neighbouring states protecting their turf by siccing the authorities on the pretext of hygiene.

Reminds me of restaurant owners suddenly developing concern for their patrons and trying to protect them from the unhygienic food in roadside eateries some time back.

Well, Mish finally addressed the real estate scenario in India and, as I expected, didn't have nice things to say about it.

There are times when you hear so many good things about something -- be it a book, a movie, or a song -- and when you finally get around to reading/watching/listening-to it, the experience is quite underwhelming because of the raised and unrealistic expectations. Cryptonomicon falls into this category for me. While portions of it were good reading (especially the crypto anarchy bits), overall the book simply rambles on and on for 900+ pages. The fact that I enjoyed Bruce Schneier's appendix on the Solitaire crypto system more than at least 50% of the book says a lot.

The Hindu on the trial of Gu Kailai:
However, a detailed account of the prosecutor’s case that emerged late last week has provided rare insights into the dealings of one of China’s most popular politicians, who was a key figure in the 25-member Politburo before his suspension in April. Part of the account was released by the official Xinhua news agency, while other details came from an Anhui student who sat in on the court’s proceedings. His account was independently verified by a lawyer who was present in the courtroom.
Read that again carefully. They're not talking about the lack of transparency regarding the government in China -- contracts, policies, and so on; they're talking about the lengths one has to go to to even know how the trial is being conducted. It's not like state secrets would be laid bare if the proceedings were not held in camera (so to speak); this is just a plain old murder case. But again, this is China we're talking about. There is a good chance that a body double would serve Ms Gu's sentence out.

On a related note, we're once again reminded of the questionable non-merit-based admission policies of Ivy League universities.

I can see where they're coming from with respect to #3 -- they don't want their pages to be polluted by the Neanderthals hanging out at rediff.com -- and find their grammar nazi behaviour naive and endearing, but I still think their backsides need a strong and liberal application of the cluestick.
