Saptapadi

The most essential rite (Sanskrit: rītī) of a Hindu marriage ceremony is Saptapadi (English: seven steps, saptapadī). Saptapadi is a Sanskrit term that means "seven steps." The wedded couple walks seven steps after tying the Mangalsutra, which is known as Saptapadi.

The couple legally becomes husband and wife after the seventh step.
Hindu wedding rituals: During Saath Phere, the bride and groom exchange their marital vows while circumambulating (walking around) the sacred fire seven times.

This is because the bride and groom exchange marriage vows and hope for a happy married life together.

1. The first marriage vow, out of seven, is a petition to the Lord for nutrition and nourishment for the Hindu bride and groom.

2. Hindu Bride and Groom: The second marriage promise is for strength in sickness, health, good times, and terrible times.

3. For the Hindu Bride and Groom - The third marriage promise is for the Hindu bride and groom's prosperity.

4. For Hindu Bride and Groom - The fourth pledge is to stand by their families in good times and bad.

Story 21 - it is about how stone elephant came to life and ate sugarcane - When Raja Abhisheka Pandyan met Ellam Valla Siddhar

கல்யானைக்கு கரும்பருத்திய படலம்

Raja Abhisheka Pandiyan went ahead to meet Ellam Valla Siddhar on the premises of the temple.On seeing the arrival of Raja, people surrounding Siddhar moved back. Abhisheka Pandiyan introduced himself to Siddhar &asked about his whereabouts.Also his purpose of visit to Madurai.

Raja asked why he performed magical acts, does he expect anything from him or people of Madurai.

Siddhar laughed & replied to Raja that he was from Kasi. He had heard a lot about Madurai in Kashi.Also told that this place is a Mukti Kshetram,so he had come to stay here.

Siddhar asked Raja if he has the capability &power to give anything that he asks for. Siddhar told King that he has power to do things even if he think of it.Siddhar asked King to ask whatever he wants & it would be provided, whatever these people had asked, they were granted.

Abhisheka Pandyan was shocked to receive such a reply from Siddhar,& he decided to test the power of this Siddhar. By that time, Raja saw a person in crowd having Sugarcane.

Raja took Sugarcane from that person.

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]

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.
