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.

Lessor known facts of Sudarshan Chakra or Neela Chakra of Puri Jagannath Temple.

The metal wheel at the top of Bhagwan Jagannath temple is also known as Neela Chakra (Blue Wheel). The wheel is made of eight metals comprising of.. 1/n

iron, copper, zinc, mercury, lead, brass, silver & gold. It's circumferance is about 36 feet & it is so designed that there is a wheel within the wheel. The circumferance of the inner wheel is about 26 feet. Eight hubs join together the inner and the outer wheels. 2/n

There are decorative designs on the outer wheel. The thickness of the Neela Chakra is 2 inches.The wheel is said to be Bhagwan Vishnu's most powerful weapon, Sudarshana Chakra. Inside Jagannath temple, Lord Vishnu's wheel is also worshipped in the name of 'Sudarshana'. 3/n

But inside the temple Sudarshana is not in the shape of a wheel, but in the shape of a small wood pillar placed to the left of image of bhagwan Jagannath. It is believed that the same Sudarshana is also at the top of the temple and is known by the name of Neela Chakra. 4/n

There is a specific category of people among the temple sevaks to serve the Neela Chakra and they are known as Garuda Sevaka or Chunara Nejoga. The pilgrims hold these sevaks in high esteem because everyday at Sunset. 5/n

शमशान में जब महर्षि दधीचि के मांसपिंड का दाह संस्कार हो रहा था तो उनकी पत्नी अपने पति का वियोग सहन नहीं कर पायी और पास में ही स्थित विशाल पीपल वृक्ष के कोटर में अपने तीन वर्ष के बालक को रख के स्वयं चिता पे बैठ कर सती हो गयी ।इस प्रकार ऋषी दधीचि और उनकी पत्नी की मुक्ति हो गयी।

परन्तु पीपल के कोटर में रखा बालक भूख प्यास से तड़पने लगा। जब कुछ नहीं मिला तो वो कोटर में पड़े पीपल के गोदों (फल) को खाकर बड़ा होने लगा। कालान्तर में पीपल के फलों और पत्तों को खाकर बालक का जीवन किसी प्रकार सुरक्षित रहा।

एक दिन देवर्षि नारद वहां से गुजर रहे थे ।नारद ने पीपल के कोटर में बालक को देख कर उसका परिचय मांगा -
नारद बोले - बालक तुम कौन हो?
बालक - यही तो मैं भी जानना चहता हूँ ।
नारद - तुम्हारे जनक कौन हैं?
बालक - यही तो मैं भी जानना चाहता हूँ ।

तब नारद ने आँखें बन्द कर ध्यान लगाया ।

तत्पश्चात आश्चर्यचकित हो कर बालक को बताया कि 'हे बालक! तुम महान दानी महर्षि दधीचि के पुत्र हो । तुम्हारे पिता की अस्थियों का वज्रास्त्र बनाकर ही देवताओं ने असुरों पर विजय पायी थी।तुम्हारे पिता की मृत्यु मात्र 31 वर्ष की वय में ही हो गयी थी'।

बालक - मेरे पिता की अकाल मृत्यु का क्या कारण था?
नारद - तुम्हारे पिता पर शनिदेव की महादशा थी।
बालक - मेरे उपर आयी विपत्ति का कारण क्या था?
नारद - शनिदेव की महादशा।
इतना बताकर देवर्षि नारद ने पीपल के पत्तों और गोदों को खाकर बड़े हुए उस बालक का नाम पिप्पलाद रखा और उसे दीक्षित किया।

PETER PADUKAM - THE LEGEND OF MADURAI MEENAKSHI TEMPLE AND A BRITISH COLLECTOR.

A British Collector named Rous Peter was appointed as Collector of Madurai from 1812 to 1828.

Though a Christian by faith, he respected all faiths including Hinduism and also honored local practice

Collector Peter was the temple administrator of the Meenakshi Amman Temple and conducted all his duties with sincerity and honesty and respected the religious sentiments of all people.

Collector Rous Peter respected and treated people of all faiths equally and this noble trait

earned him the popular nickname ‘Peter Pandian'

Goddess Meenakshi Amman Temple was situated between Collector Peter's residence and office.

Everyday he used to go to the office by his horse and while crossing the temple, he got down from his horse, removed the hat and his shoes

and crossed the whole path on his foot.

Through this small gesture he expressed his reverence to the Goddess!

One day there was a heavy downpour in Madurai city and River Vaigai was in spate.

Collector was sleeping in his residence and was suddenly disturbed and woken up by

the sound of anklets and he left his bed to find out from where the sound had came.

He saw a small girl wearing pattuvastrams (silk garments) and precious ornaments and addressing him as 'Peter come this way'.

ugh i wanted to do a thread about the wars in Star Wars and how the two outlying wars (the clone wars in the prequels and the cold war/civil war in the sequels) are really weird but i don't feel like it any more.

my first argument is that the Clone Wars were a really complex morally gray moment in Star Wars canon in like, 5 different directions and I'd kind of like to know why Lucas did that.

especially with the direct line that's drawn in the OT with the allegory of WW2 and Vietnam with the rebels being the Vietnamese and the Empire being America. That...doesn't exist in the Clone Wars.

for starters: it's weird it's called the Clone Wars. I get why, because that's what Kenobi calls it in STAR WARS, but the clones are a small facet in the larger story of the war.

the clones basically only exist as a macguffin in AOTC that is...extremely confusing ultimately. Because if you accept that Sidious has this grand master plan to use this war to destabilize the Republic and form an Empire...it's way too complex.
