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.

You want to know something about how bullshit insane our brains are?
OK, so there's a physical problem with our eyes: We move them in short fast bursts called "saccades", right? very quick, synchronized movements.
The only problem is: they go all blurry and useless during this

having your vision turn into a blurry mess every time you move your eyes is obviously not a good idea, so our brains hide it from us. Now, imagine you're an engineer and you have this problem.

You've got some obvious solutions you could do.
1. make the vision go black during movement. (Some VR games do this!)
2. just keep showing the last thing we saw prior to movement

both are good options with different downsides, but OH NO. this is assuming everything makes sense and is chronological and (regular) logical.
Your brain does neither of these options, really.

first, it basically puts your visual system on "pause". You're not seeing blackness or even nothing, you're just not seeing period.
then when you finish your saccade, it shows you what you now see at the new position. and then it pretends it can time travel.

TILAK:AN AGE OLD PRACTICE OF HINDUS

The beautiful Matribhumi of Bharat is the land of many religions &cultures but its Hinduism with which the world identifies this great Nation. Hinduism is the religion with science at its heart &its also a religion of many rituals &traditions.

Today we will talk about a very prominent and noticeable Mark on the foreheads of #Hindus called 'Tilak'. Tilaks are of different designs and colors. It symbolizes different meanings for different people such as religious expression, spiritual symbol, marital status etc.

Tilak is a very alluring design that is made in between the eyebrows. Vermilion, Chandan, Turmeric, Kumkum, Rice and Rice water, Vibhuti etc can all be used as Tilaks.
Why this particular spot is used for Tilak? Bcoz, it is mentioned as 'Ajna Chakra' in terms of yoga.

This chakra is the sixth & most important chakra of the human body. It's the junction where the highest number of neurons meet & is described as most important and sensitive spot in the human body.Different #Hindu traditions use different shapes and ingredients to make the Tilak.

SPIRITUAL SIGNIFICANCE

Various Hindu Scriptures mention the importance of Tilak in Sanatan Dharma. It is believed that energy, strength and divinity comes to those who apply Tilak. It is also regarded as a welcoming expression and to honour the guests when they arrive.

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.

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.
