Chennimalai Murugan Kovil
#Erode
#TamilNaduTemples 🚩

Chennimalai Murugan Temple is located  near Perunthurai in Erode District. Murugan is worshipped here as Dandayudapani. Temple is situated on the banks of Noyyal river also called Kanchima Nadhi. Temple is situated in a hill

Sthala Puranam says that, there lived a Landlord who had many cows in his farm. One among them was a Black Cow, which didn't give milk. Land lord observed that evening time, when all the cows came back after grazing, this cow used to go to a particular spot and gave all  the milk

by itself. He decided to dig the spot where the cow gave its milk

On digging a beautiful Vigraham of Murugan was found, but lower portion was very rough. So he called a great sculptor to soften it. Everyone was shocked to see that on the first chisel the vigraham bleeded.

Land lord realized that Murugan wanted the Vigraham the way it was.

Thus Prathishta was done on Chennimalai hill. It is believed that Sivalaya Chola got relieved from his Brahmahatti Dosha here. Kanda Shasti Kavacham was first offered here.

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.
