Ok. Dvija means twice born. Dvijas are Brahmins, Kshatriyas and Vaishyas. Ezhavas and Thiyars are outside varna system but were not regarded as Dalits bcoz they were free unlike Dalits who were slaves. They had to endure caste discrimination but a lesser degree compared to Dalits

RISHI ASHTAVAKRA(DEVAL)

Those who are well versed in our ancient scriptures must definitely have come across the name of Ashtavakra Muni. Who was he and what is the story behind his body getting crooked from all sides.

Muni Asit was the son of Pracheta Rishi.

He was childless and this caused a lot of worry to him. But an Akashvani assured him that he should go to Shivji to get all his
worries nullified.

So he along with his wife go to Shivji and after paying him obeisance start singing Shivji's praises.

He describes Shiv as the one who is beyond any other thing, whose glory has no words to describe. After this the couple stands with folded hands in front of Rudradev. The strotras sung in praise of Shiv possess magical qualities even today.

Shiv gets satisfied by them soon and is ready to grant a boon.

Shiva told him that, he very well knew what the Muni desired. He then gives him the "Sansaar Vijay' mantra and asks him to keep reciting it. The Isht devi would come at an appropriate time and fulfill his wish.

Asit Muni kept reciting this mantra for hundred years. The Devi appeared and granted him the boon of a son as a Shivansh. A son was born and was named as Deval. He grew upto be a great scholar well versed and a handsome young man. Asit Muni got him married to Ratnamalavati.

Pretending that voting for Trump or denying climate change or suggesting the solution to every problem is more guns is a legitimate point of view, worthy of respect is not "how America works." It is how it dies.

People in a free society are entitled to any point of view no matter how obviously wrong or outlandish or destructive provided they do not impose their views on others.

But suggesting that something ignorant or divorced from reality warrants the same kind of treatment in public debate as something based in fact or at least credible is absurd and when done on behalf of a society in public media or academic settings it is self-destructive.

We would not grant media coverage or much bandwidth at all to a group that argued that unicorns exist or that there was a pot of gold at the end of the rainbow. Yet views like denying climate change or basing policy decisions on sweeping, obvious lies, are just as unsound.

Somewhere, somehow, judgments must be made. Some behaviors are wrong and must be condemned. Someone must challenge lies and demand facts. Coddling people who embrace idiocies does not help them no matter how loudly they demand to be coddled.

Important paper from Google on large batch optimization. They do impressively careful experiments measuring # iterations needed to achieve target validation error at various batch sizes. The main "surprise" is the lack of surprises. [thread]

https://t.co/7QIx5CFdfJ

The paper is a good example of lots of elements of good experimental design. They validate their metric by showing lots of variants give consistent results. They tune hyperparamters separately for each condition, check that optimum isn't at the endpoints, and measure sensitivity.

They have separate experiments where the hold fixed # iterations and # epochs, which (as they explain) measure very different things. They avoid confounds, such as batch norm's artificial dependence between batch size and regularization strength.

When the experiments are done carefully enough, the results are remarkably consistent between different datasets and architectures. Qualitatively, MNIST behaves just like ImageNet.

Importantly, they don't find any evidence for a "sharp/flat optima" effect whereby better optimization leads to worse final results. They have a good discussion of experimental artifacts/confounds in past papers where such effects were reported.

"How the Avengers would respond to the Capitol riot" (a thread)

CAPTAIN AMERICA - tells Falcon, "I fought Nazis once before. They're extremely dangerous." They then see the guy scaling the Capitol wall fall into the shrubs. Falcon: "You sure these are the same Nazis?"

IRON MAN - lands by the guy carrying the podium. Says, "Mind if I borrow this?" then tosses it to Hulk, who swings it like a bat at the mob. Guy: "Hey, that's MY podium!" Iron Man: "Actually it's the Speaker's. And technically, it's a lectern." Then punches him through a wall.

BLACK WIDOW - enters hotel room where Jack Dorsey is tied up. Rips duct tape off his mouth. Jack: "I'll do anything you want!" BW: "Disable POTUS's Twitter. NOW!" Jack fumbles with his phone. "Done. Anything else?" BW: "Yeah. Trim your beard for God's sake." *tosses him clippers*

HULK - grabs a selfie stick from one of the guys and beats him over the head with it. Deeming it too small, he grabs another guy's Confederate flag and takes out a whole swath of rioters. He then tosses the flag to Cap, who uses it as a javelin to impale a fleeing Ted Cruz.

HAWKEYE - hears Iron Man in his earpiece say, "Looks like Orange Julius is tweeting from another account." Hawkeye: "On it." He locks in on Trump through the White House window and fires an arrow, knocking the phone out of Trump's hands. Hawkeye: "Damn that felt good."
