Due to the pandemic you may not have visited your local library in a while. So come with me on a virtual library tour, courtesy of stock photography, to see what we do for a living...

Libraries are of course information resource centres, but in many ways they are so much more. To get the best out of them you need to really know your way around the stacks.

The enquiries desk is normally your first stop in a library, and this is where you will meet The Angry Librarian! Why is she angry? Because you keep asking her stupid questions!

"Are you open?"
"Do you have a toilet?"
"That chair's wobbly!"
"Why isn't it available in audiobook?"
"Someone else is on the computer and that's not fair!"

On and on it goes...

And that's why in the library we insist on silence. It's the only way to stop us swearing at all the idiotic things you ask us. And we've looked up a lot of old swear words: beardsplitter, bescumber, rantallion, smellfungus etc. We're such muckspouts...

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.

Rani Chennamma of Kittur was one of the first women rulers of India who fought against the might of the British Empire in 1824. Rani Chennamma was born in 1778 in a small village of Kakati in Belgaon distt of the State of Karnataka.

She was born into the Lingayat Community to a man named Dhulappa Desai. From a very young age she was trained in horse riding,sword fighting, archery and diplomacy. At a very young age of 15 yrs, she was married to the King of Kittur and became the Queen of Kittur.

It is said that King of Kittur Mallasarja was once moving around in the neighbouring kingdoms to find support to fight Tipu Sultan. It is then, when he came across Chennamma and he immediately got attracted to her sheer confidence and bravery.

Rani Chennamma and King Mallasarja had a son together who died very soon after the death of King Mallasarja in 1816. As the Queen of Kittur, Rani Chennamma immediately adopted Shivalingappa as her son and declared him the heir to the throne of Kittur.

This did not go well with the British East India Company who was enforcing the Doctrine of Lapse those days, according to which the adopted children of the Indian rulers were not allowed to become their heirs and if the native rulers did not have children of their own, their...

Velimalai Kumaraswamy Kshetram
Kumarakovil, #Kanyakumari
#Tamilnadutemples 🚩

Velimalai Kumaraswamy Temple is a Murugan temple located in Kanyakumari District of Tamilnadu.

Muruga faces east and is said to be facing Sthanumalayan (Paramashiva) of Suchindram. Muruga is of

eight feet vigraham and Valli thayar is six feet tall. Eventhough Thiruthani is believed to be the place where Subrahmanya married Valli, it is also believed that Valli’s thayar's marriage took place with Murugan here.

There is a Kalyana Vinayakar sannidhi
who helped Muruga's

marriage with Valli. Kumarakovil is also known as Kumara Kshetram and Subrahmanya Sthala. The Tamil epic Chilapathikaram refers to the temple as Chera Nattu Aeragam

Wedding of Valli and Murugan is celebrated here in the Tamil month of Panguni (March-April).

Om Muruga
