1/ One of the best things I did in 2020 was to join a growth marketing program called @growclass

I’d seen it hover around online, I saw some friends talking about it. But I thought, wow, that looks great but it’s too expensive for me at the moment.

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.

Shri Hanuman had boon to be immortal. And be present where ever there is Ram stuti.
I came across this beautiful story that I would like to share
#threadstories
#Hanuman ji is believed to live in the foothills of Himalayas. But once he spent a lot of time in Sri Lanka

Where Ravan's brother ruled for many years..
On his way back he came across tribal people from community called #Mathanga
He gave Darshan to them. The chief of the tribe asked him to keep coming back to guide their generations
Hanuman ji said that whoever recites this mantra
2/9

I will give them Darshan. But there are two conditions
1st he/she must know his relationship with me
2nd there must not be anyone around him in 950 mts radius. If present, that person must also know about my relationship with him /her.

He promised to come after every 41 yrs

The Mathangs also maintain a ‘logbook’ where they record all the words spoken and ‘leelas’ performed by Lord Hanuman.
They call him their Guru
Who teaches them how to live their lives.
A Sri Lankan organization called Setuu is studying this ‘logbook’ and also conduct

programmes for Hanuman devotees who can do ‘Sadhna‘ under the guidance of Setuu masters. Devotees who qualify all the criteria will be eligible for Hanuman’s ‘sakshaat darshan‘
The Setuu has certain conditions that need to be kept in mind which includes devoting one complete

Hinduism is a minority religion in Punjab.

During the Khalistan movement, the minority Hindus and Jains were subjected to several attacks. Hindu and Jain temples were frequently vandalized and desecrated. This thread documents a few instances.

Durgiana Mandir is one of the oldest temples of Amritsar. According to the regional Hindu tradition, the temple was built on the spot where Lava and Kusha bound Hanuman. The temple annually attracts millions of Hindus from all over the country.

Amristsar has a very ancient Hindu history.

According to the regional Hindu tradition recorded in the "Survey of Amritsar", Amritsar got its name from Amrit immersed by Lava and Kusha in a pond.

Durgiana Mandir was rebuilt in 1921.

It was used to house the Murtis of Vishnu and Durga which were thrown out from the Parikrama of Harmandir Sahib in 1905.

Because of its presence in Amritsar, it became a frequent target of radicals during the Khalistan movement.

In 1982, in what was a completely unprovoked attack, the Dal Khalsa "activists" threw a severed cow head inside Durgiana temple.
