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]

https://t.co/7QIx5CFdfJ

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.

10 Signs of Social Intelligence 🧠

1-Smile
2-Good posture
3-Strong eye contact
4-Fluid hand gestures
5-Let’s others talk more

[ QUICK THREAD ]

1-Smile

How do you feel when you see someone that looks angry?

It’s a downer

No one will want to interact with you if you look pissed all of the time, it’s just negative energy

Plus, smiling is a sign of confidence and boosts others moods

2-Good posture

Don’t walk Into any social setting looking like the hunchback

It’s weak and makes you look low energy

Plus, you’re displaying low status with weak posture

Stand up straight with your chin up & chest out like a god

Walk like you’re proud of yourself

3- Strong eye contact

Ever shake someone’s hand & their eyes are either looking down or darting?

It’s weak & you probably won’t trust them

Or in conversation?

Eye contact while talking means you’re listening and paying *Attention*

Strong eye contact displays confidence

4-Fluid hand gestures

Use your hands to talk & express your points

Don’t stand there like a robot

Using the hands can make what you’re talking about exciting

It can also be used to emphasize

Exciting = positive emotion

Remember, making people FEEL is what’s important

Saptapadi

The most essential rite (Sanskrit: rītī) of a Hindu marriage ceremony is Saptapadi (English: seven steps, saptapadī). Saptapadi is a Sanskrit term that means "seven steps." The wedded couple walks seven steps after tying the Mangalsutra, which is known as Saptapadi.

The couple legally becomes husband and wife after the seventh step.
Hindu wedding rituals: During Saath Phere, the bride and groom exchange their marital vows while circumambulating (walking around) the sacred fire seven times.

This is because the bride and groom exchange marriage vows and hope for a happy married life together.

1. The first marriage vow, out of seven, is a petition to the Lord for nutrition and nourishment for the Hindu bride and groom.

2. Hindu Bride and Groom: The second marriage promise is for strength in sickness, health, good times, and terrible times.

3. For the Hindu Bride and Groom - The third marriage promise is for the Hindu bride and groom's prosperity.

4. For Hindu Bride and Groom - The fourth pledge is to stand by their families in good times and bad.

THE UNTOLD TALE OF THE LESSER KNOWN WARRIORS:JOGRAJ GURJAR & RAMPYARI GURJAR AND HOW DID THEY DEFEAT THE CRUELEST ISLAMIC INVADER, TIMUR LANG.

Timur Lang, was the founder of Timurid Empire. He was born in April 1336 CE, somewhere in central asia.

During his reign, he conquered Persia, Egypt, Central Asia and emerged as the most powerful and heinous ruler. He was a religious fanatic like the rest of the Islamic invaders who tried to invade India.

Timur Lang decided to invade India in 1398 as he heard about India's splendid wealth and had a desire to conquer India which his ancestor Genghis Khan couldn't do.

After Firoz Shah's demise in1388, Delhi Sultanate was in a state of political turmoil.During this time, Timur sent his grandson Pir Mohammad to attack Indian front. He invaded Multan&was able to defeat Iqbal Khan's brother but when he met with resistance,he asked help from Timur.

Iqbal Khan secured his hold on Delhi under Muhammad Tughluq after Firoz Shah died.
Timur provided the required back-up to his grandson with 100000 men approx. Timur sacked and plundered all the cities coming in his way &later in October 1398 reunited with his grandson.

Yantrodharaka Anjaneya Temple, Hampi, Karnataka.

This temple dedicated to pawanputra Hanuman, near the banks of Tungabhadra river was built by dwaita philosopher and rajguru of the Vijayanagar empire, Sri Vyasaraja around +500 years ago.

:It is only in this temple that Hanuman appears in a prayer position. In this image, Bhagwan Hanuman’s crown has been formed by his tail.12 monkeys have been carved around this amulet.

:They represent the 12 days Sri Vyasaraja prayed to Hanuman ji. Each monkey holds the tail of the monkey in front of him but is facing backward. Seed syllables have also been carved around the amulet.

:It is believed that Sri Vyasaraja used to draw a picture of lord Hanuman here on the rocks before offering prayers using charcoal and the sketch disappeared after prayers.This incidence happened for 12 days in a row until he pleaded to bhagwan to appear in front of him.

On the 12th day, Hanuman ji appeared in front of Sri Vyasaraja and blessed him. Hanuman asked Sri Vyasaraja to constrain him in a hexagonal amulet & install him in that place.
