We introduce a new paradigm for dataset creation based on human 🧑‍💻 and machine 🤖 collaboration, which brings together the generative strength of LMs and the evaluative strength of humans. And we collect 🎉 WaNLI, a dataset of 108K NLI examples! 🧵

Paper: https://t.co/IUXcm9wIh2

Our pipeline starts with an existing dataset (MNLI), and uses data maps 📜 to automatically identify pockets of examples that demonstrate challenging 🧐 reasoning patterns relative to a trained model. Then we use GPT-3 to generate new examples likely to have the same pattern. 2/

Next we propose a new metric, also inspired by data maps, to automatically filter generations for those most likely to aid model learning. Finally, we validate ✅ the generated examples through crowdworkers, who assign a gold label 🟡 and (optionally) revise for quality ✍️. 3/

Remarkably, replacing MNLI with WaNLI (which is 4x smaller) for training improves performance📈 on seven OOD test sets🧪, including by 11% on HANS and 9% on ANLI. Under a data augmentation setting, combining MNLI with WaNLI is more effective than using other augmentation sets. 4/

Our method addresses limitations of crowdsourcing, where workers may resort to repetitive writing strategies 🤷, and leverages the great progress in text generation 📃. We get the best of both worlds: 🤖’s ability to produce diverse examples, and 🧑‍💻’s ability to evaluate them. 5/

We hope our work demonstrates the promise of leveraging LMs in a controlled way to aid the dataset creation process, and encourage the community to think of dataset curation as an AI challenge itself 💡. Co-authored with @swabhz @nlpnoah @YejinChoinka 💟 6/6

MEENAKSHI AMMAN, MADURAI (TN)
#bharatmandir #navratri2021

A paadal Petra sthalam where Shiva took the form of Sundareswarar (the handsome one) and married Devi Parvati (Meenakshi).
Devi is also known by the name Angayarkanni (mother with the beautiful fish eyes).
@GunduHuDuGa

Devi Meenakshi emerged from yagna fire as a 3 year old girl when Pandyan King Malayadwaja and Kanchanamalai were praying for a child.
It is said that Devi was born with three breasts and there was a prophesy that her superfluous breast would melt away when she met her husband.

Devi ruled over Madurai and captured Indralok. She went on to capture Kailasha. When she saw Shiva, her 3rd breast disappeared and she realised that Shiva would be her consort.
The divine marriage was attended by all Devas and Sri Vishnu (as her brother) gave her hand to Shiva.

It is said that Indra found a swayambhu lingam at Kadamba Vanam. He placed it in Madurai where the kshetram stands. Here, Shiva is seen on the vehicle of Indra.
The Golden Lotus Tank is said to be the place where a golden lotus blossomed for the puja performed by Indra.

The Meenakshi Thirukalyanam festival is celebrated in the Chithirai month to mark the divine marriage of Meenakshi Amman. The festival includes a procession where Meenakshi and Sundareshwara travel in a chariot and Sri Vishnu gives away his sister in marriage to Shiva.

one of the things i like about Batman is that it's fundamentally about being orphaned, and being an orphan — how this guy stays tethered to the world in his own weird, abstract, extrajudicial way when he feels that his link to it has been violently severed

Batman does this by permanently recapitulating his own trauma: solving crimes for other people, protecting them. But that's actually just the beginning; he also recapitulates his own experience of orphanness by essentially raising several orphans

Dick is an orphan in the traditional sense: dead parents. Batman sees it happen. Jason, less so: missing dad, known mom who eventually dies. Tim, even less so: parents are around a while, and involved, before both dying. Carrie, even less than that: negligent parents.

Steph: evil father, who openly works against her. And then there's Damian, whose parents are both alive and yet both have identities that totally obliterate their role as his parents. He doesn't relate to them as a mother and father; he can't, and neither can they.

In all these different cases, Batman tries all these different ways of making orphanness for them not what it was for him: Either by trying to teach them the (arguably poor) coping skills early that he learned over a very long time, or by literally legally adopting them, etc.

A thing which I unironically and enthusiastically believe which is unpopular among smart people of my acquaintance: financial engineering has in the recent past and present contributed substantially to human welfare. We should hope to see more of it.

Maybe more geeks need to meet someone who says “My job is teleporting value across time and space.”

Financial engineering is sort of a squishy term. I don’t primarily mean payments infrastructure or financial rails, although both of those involve substantial engineering.

I mean more “We took a thing and performed some alchemy, and now have a new thing.”

Except instead of alchemy it is generally quite a bit of math, a huge amount of contract law and due diligence, often an impressive amount of ops work, and a dusting of technology that web devs would recognize as such.

You want to buy a house.

You take a loan from the bank.

The bank asks you, “what if you don’t pay back?”

You say, “take my home and sell it”.

(Thread)

That makes sense. The bank gives you a loan and in case you don’t pay, the bank will take over your house and sell it and recover its money.

That’s collateral.

Banks also lend money to big corporations. With them, banks don’t always have collateral.

So a loan where the bank has collateral is considered safer for the bank.

In the early 2000s, the banks in the USA were giving out loans to people for buying houses.

The economy had just recovered from the tech bubble in 2000 where many banks had given out loans to businesses that had shut down.

In that backdrop, the banks found giving home loans safer.

PAKISTAN-INDIA WATER ISSUES – HOW INDIA STOPPED WATER IN PAKISTAN's CANALS IN 1948

Thread

After partition in 1947, the water system was also bifurcated between Pakistan n India.

India cheated Pakistan when on April 1, 1948, India suddenly n without warning stopped...
1/n

...the supply of waters flowing into Pakistan's Central Bari Doab and Dipalpur Canals.

The boundary award on the partition of the sub-continent had left the headworks of these canals in Indian territory, and in accepting it India had implied her willingness to leave...

2/n

...the historic distribution of common waters undisturbed.

India's action was therefore in flagrant disregard not only of international law n morality, but of her solemn commitments with Pakistan and a gross violation of this country's historical rights over common waters.

3/n

Faced with a threat of utter desolation of millions of acres of fertile land, Pakistan had perforce to sign a document with India in which she agreed to "India's progressively diminishing water supplies to these canals and to the West Punjab government's tapping...

4/n

...alternative resources".

A specific reservation was made in the document with regard to India's claim that she had full property rights over waters flowing into her territory, and could therefore use them as she liked.

The issue was, however, to be examined...

प्राचीन काल में गाधि नामक एक राजा थे।उनकी सत्यवती नाम की एक पुत्री थी।राजा गाधि ने अपनी पुत्री का विवाह महर्षि भृगु के पुत्र से करवा दिया।महर्षि भृगु इस विवाह से बहुत प्रसन्न हुए और उन्होने अपनी पुत्रवधु को आशीर्वाद देकर उसे कोई भी वर मांगने को कहा।

सत्यवती ने महर्षि भृगु से अपने तथा अपनी माता के लिए पुत्र का वरदान मांगा।ये जानकर महर्षि भृगु ने यज्ञ किया और तत्पश्चात सत्यवती और उसकी माता को अलग-अलग प्रकार के दो चरू (यज्ञ के लिए पकाया हुआ अन्न) दिए और कहा कि ऋतु स्नान के बाद तुम्हारी माता पुत्र की इच्छा लेकर पीपल का आलिंगन...

...करें और तुम भी पुत्र की इच्छा लेकर गूलर वृक्ष का आलिंगन करना। आलिंगन करने के बाद चरू का सेवन करना, इससे तुम दोनो को पुत्र प्राप्ति होगी।परंतु मां बेटी के चरू आपस में बदल जाते हैं और ये महर्षि भृगु अपनी दिव्य दृष्टि से देख लेते हैं।

भृगु ऋषि सत्यवती से कहते हैं,"पुत्री तुम्हारा और तुम्हारी माता ने एक दुसरे के चरू खा लिए हैं।इस कारण तुम्हारा पुत्र ब्राह्मण होते हुए भी क्षत्रिय सा आचरण करेगा और तुम्हारी माता का पुत्र क्षत्रिय होकर भी ब्राह्मण सा आचरण करेगा।"
इस पर सत्यवती ने भृगु ऋषि से बड़ी विनती की।

सत्यवती ने कहा,"मुझे आशीर्वाद दें कि मेरा पुत्र ब्राह्मण सा ही आचरण करे।"तब महर्षि ने उसे ये आशीर्वाद दे दिया कि उसका पुत्र ब्राह्मण सा ही आचरण करेगा किन्तु उसका पौत्र क्षत्रियों सा व्यवहार करेगा। सत्यवती का एक पुत्र हुआ जिसका नाम जम्दाग्नि था जो सप्त ऋषियों में से एक हैं।
