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.

Many readers have asked me "why do so many pulp covers feature women in ripped red blouses standing in swamps while a man fights off an unusual animal attack?"

The answer is artist Will Hulsey...

Will Hulsey was the undisputed king of the animal attack pulp cover. You name it, he'd paint it attacking you in a pool of stagnant water.

Very little is known about Will Hulsey, but he worked on a number of men's pulp magazines in the 1950s and early 1960s including Man's Life, True Men, Guilty, Trapped and Peril.

Their audience was ex-GIs: during WWII the US Council of Books in Wartime had given away over 122 million books to American servicemen to read; this led to a post-war surge in paperback and magazine sales amongst these newly enthusiastic readers.

As a result the 1950s saw a raft of men's pulp magazines being published to tap into this market - almost 200 different titles!

Magudeswarar Temple, Kodumudi
#Erode
#Tamilnadutemples 🚩

Situated on the banks of the river Kaveri, Magudeswarar Temple is one among Paadal Petra Shiva Sthalam. Kshetram is famous Parihara Sthala for Naga Dosham and for performing Tarpanam to the departed souls.

There are 3 sannidhi here for Paramashiva, Mahavishnu and Brahma Deva.

Sthala Puranam says that once Adisesha and Vayu Deva placed Meru parvat at the centre to decide who is stronger among them. Parvatam was held tightly by Adisesha and Vayu blew the wind to push Parvatham.

In this struggle, peak of meru  parvatham broke into 7 pieces and fell in different places as precious gems. Diamond fell at  Kodumudi as Magudeswarar. Panchamirtham abhishekam is very famous here. Vanni tree situated here is very old which contains medicinal values.

It is believed that Agasthiya Muni did Prathishta of Shiva Lingam here. As Adisesha is one of the reason for creation of the temple, this is famous Parihara Sthalam for Naga Dosham. It is believed that those who

who take a bath in the river Kaveri and worship paramashiva and mahavishnu, will be cured of diseases and will get relief from all illness.
