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.

THE SCIENCE BEHIND YAJNA

Fire is, of course, one of the greatest discovery of mankind. Our control over the fire dramatically changed the entire human habits; earlier it was used to cook food, protection from animals and to stay warm.

Among the many applications of fire, one is Yajna (यज्ञ, yajña); also called as Havana (हवन) or Agnihotra (अग्निहोत्र).
Yajna is elaborately described in Yajurveda. In Yajurveda, Yajna is the greatest among all works (Karman). One can purify his /her soul by performing Yajna.

In Vedic culture, it is thought that the holy fire is the mediator between Gods and us; when the offerings are made to Yajna with chanting mantras, it directly reaches the Gods, who bless the people with rains, food, health, and good luck.

According to Apastamba Sutra, the definition of Yajna is Vedic sacrifice; an act by which we surrender something for gods e.g. grains (Anna), pulse, milk and milk product (ghee, butter, curd) fruits, plant juice (soma), etc.

As we said; Yajna is the contact medium for gods and

to seek their blessings.

There are many types of Yajna performed by Hindus for e.g.,

1. Rajsuya Yajna
2. Ashwamedha Yajna
3. Chaaturmasya Yajna
4. Vaajpey Yajna
5. Purushmedha Yajna
6. Sarvamedha Yajna

Here is George Washington (with bow and arrow) pictured alongside the Goddess of America. 1/

Here is Christopher Columbus (seated at center) reporting his discovery of America to Queen Isabella of Spain.

So far, kinda normal, but wait for it.... 2/

Now it's the American Revolution. Here is George Washington defending his wife "Carol" from a British official named "Asura" (same characters as the Buddhist deity). 3/

And here is Washington's "second-in-command" John Adams battling an enormous snake. 4/

Here is Washington and his wife "Carol" meeting an extremely youthful Benjamin Franklin, who has an impressive squat. 5/

Beautiful Story of Guruvayurappan

Poonathanam Namboothiri was a great devotee of Guruvayurappan. One day Poonthanam was going to Guruvayur Kshetram. It was night time and eventhough Namboothiri was tired he continued to walk

Suddenly some thieves came and blocked his way. Poonthanam cried for Shri Krishna to help. Thieves snatched all valuables from him, but Namboothiri holding his Bhaghavatam book called Shri Krishna to help. That time a man came in a horse back and fought with thieves and protected

Namboothiri. Poonthanam thanked Krishna for helping him from danger and said to the man that "Shri Krishna has send you here and I don't know how to thank you".  The man smiled and told that he is Mangattachan, minister of  samoodhiris. Poonthanam once again thanked him and

gave his ring to Mangattachan as a token of thanks and continued his journey. He reached Guruvayur early morning for Nirmalya Darshan. Temple poojari came near him and told that Guruvayurappan came in his dreams and asked to hand over the ring to poonthanam.

When he opened Kshetra Nada poonthanam was surprised to see his ring on Guruvayurappan, which he gifted to Mangattachan. He understood that it was Guruvayurappan who came as Mangattachan to protect him. This is how Bhagwan treat his devotees.

FB POST BY MR PRABEER BASU,
IAS-1976(BIHAR)
" Received a hurtful post from an old friend and colleague. He was on my daily Broadcast list of WhatsApp. He requested that I do not send him any of my posts on 'political' issues. I gave him a long explaination

on why I write and what I write. But he was not convinced.

Being alerted by him thus, I felt I should clarify to all who read my posts on what exactly I think and do.

The charge against me is that I wrongly support our current Prime Minister, Shri Narendra Modi..

and that it establishes I am not rational and impartial anymore.
Let me try and explain.First and foremost,I do not write on 'political' issues. I write on 'national' issues. For example, I have no opinion on whether Rahul Gandhi should be President of his party or not.

Similarly, I have no views whether BJP is a better party than Congress or vice versa.
Even after 36 years in the IAS I have no MLA, MP or anyone involved in politics whom I can classify as my friend or even acquaintance.

So, naturally I don't care which party wins or loses as long as the winning party runs an honest government doing good to my nation.
Now, why I speak in favour of Shri Modi:

1. Ever since the beginning of my service I realised that Planning Commission was not serving..
