🌺A Very Interesting Comparison🌺

Till some time ago, religion and science were considered to be opposites, but now many similarities are coming out from the conclusions drawn from the analysis of scientists and scholars. But whenever it comes to Bhagwan Shiv, science..

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 LESSER KNOWN MAHARANA OF MEWAR:RANA KUMBHA
Kumbalgarh Fort is one of most spectacular sites of India,atop a hill abt 3600ft above sea lvl in the https://t.co/LkjmzzBhE2's second largest wall is surrounding it.A fort wall second only to Great wall of China,still not so famous.

This longest wall of India stretches to almost 36Km and encompasses a few hills, many step wells and over 360 temples and palaces. Birth place of the Great Maharana Pratap, this fort is named after another Great Maharana of Mewar, who is not given his due in the History.

Builder of many architectural marvels like the Kumbhalgarh Fort, an erudite scholar, a patron of arts, music, culture & a great warrior was the Great Maharana Kumbha. Yet we don't know much about him. Let's get to know him a little.

Maharana Kumbha was the undefeated King of Mewar from 1433-1468CE.He never lost any battles &kept Mewar out of the reach of Islamic Invaders till the time he was alive. Born on Makar Sakranti to Maharana Mokal & Saubhagya Devi, Rana Kumbha was only 13 when he ascended the throne.

His father was killed by his own relatives in a political conspiracy. He was a powerful King about 8ft tall &charismatic personality,a hardcore Hindu Rajput who could shed his life for Hindu honour without thinking twice.He was an ardent skillful warrior who never lost a battle.

The BATTLE OF PAVAN KHIND (13 July 1660)

300 MARATHAS against 10000+ ADIL SHAHI TROOPS

A Sparta style last man stand at a mountain pass which ensured Shivaji Maharaj's safety.

Valour, loyalty and sacrifice!

Baji Prabhu Deshpande was one of the most able lieutenants of Shivaji. He sacrificed his life defending Shivaji in a heroic last stand known as the "Battle of Pavan Khind" in which his force was hugely outnumbered.(1)

In this battle he became a martyr, but managed to halt the enemy forces for several hours, which secured Shivaji’s safety and victory on another front. Without this heroic last stand Shivaji’s glorious career may have been cut short.(2)

Baji Prabhu was senior to Shivaji. In the beginning he opposed Shivaji being from a rival Maratha clan, but realised that Shivaji stood for national resurgence. Henceforth he became a friend and loyal supporter of Shivaji.(3)

In 1660, Shivaji was trapped in the fort of Panhala, under siege and vastly outnumbered by an Adilshahi army led by general Siddhi Jauhar.(4)

1/ I am seeing more and more founder secondary in venture rounds (Secondary = founders selling some of their shares before some other shareholders are able). Series B-D. I see both as an investor and through entrepreneur circles.

2/ I like secondary for entrepreneurs. Moderation is key but in a lot of situations I think it helps accelerate the co. Lots of very smart investors disagree. Here are my thoughts.

3/ Magnitude: My basic rule of thumb from what I see is market is 4+ yrs and up to 10% of founder’s equity stake with some $ cap that makes sense given stage etc. (typically <$10m)

4/ The entrepreneurial journey is brutally hard. Giving some financial relief helps remove one piece of pressure. I don’t think that secondary in the magnitude mentioned impacts the drive/persistence of great entrepreneurs.

5/ That secondary means they will be able to just sleep knowing they can pay their kids’ tuition. Secondary will make most founders better at their jobs, thus accelerating the co.
