The worst taught skill in machine learning is model validation.

If you can’t validate your models well, you have no idea if they will actually work.

Here are 3 steps I’d take if I was relearning model validation from scratch 🧵

1) My Stan Lee story happened when I was in 5th grade. I was visiting NYC with my Dad and had read the address for Marvel in the comics I read constantly. I begged my Dad to take me and to his credit he did. And guess what? It was just an office.

2) We were down in the lobby and I was kind of crushed. I don’t know what I expected, The Thing and the Yancy Street Gang to be sitting around smoking cigars? Anyway, my Dad was taking a beat to figure where we were going next and a guy came up to us.

3) He was wearing a white shirt and tie and said to Dad “Is he disappointed because. The Marvel offices were just offices?” My Dad said yes and then the guy who had gray around his temples and a mustache said “hold on a second” and opened one of those office mailboxes with a key.

4) He then handed me a thick stack of EVERY SINGLE MARVEL COMIC COMING OUT THE NEXT MONTH. “Here you go. Keep reading Marvel comics” he said and then walked off. I left in a daze and about 15 minutes later it hit me “Gray around the temples, mustache... That was Stan Lee!”

5) Later when I wrote on the Ant Man movie I told Kevin Feige the story, the year, look of the guy etc and Kevin said “That’s exactly the kind of thing Stan would do and he would have been there then. That was him.” Rest In Peace Stan Lee and thank you for the comics.

Thiruvizha Mahadeva Kshetram
#Alappuzha 
#Keralatemples 🚩

Thiruvizha Mahadeva Kshetram is located in Cherthala and it is believed that Prathishta of temple was done by Vilwamangalam Swamy. Paramashiva is Swayambhu here and is worshipped as Kalakandha which means who swallowed

Halahala visham to save the world during Samudra mathanam. 

It is a famous temple where people seek the blessings, for curing the Kaivisham. The poison given by someone to destroy a person is made to vomit here. This is removed by making them vomit the poison by a special

medicine.
The medicine for vomiting is made from a plant near temple by Palodathu family. The milk offered to Bhagwan is mixed with the extracts of the plant.

Story says that once this place was a dense forest, and a woman was looking for the presence of a tortoise in the pond

and the tip of her stick hit the bottom and it started bleeding in the pond. 
Frightened, the lady informed every one and after searching in pond people found Swayambhu Lingam inside the pond. Thus Prathishta was done here.

Om Namah Shivaye

#3/thread on Angkor wat

Christianity and islam may be the largest religion of today’s world but Sanatan dharm has the largest religious monument in the world in the form of Angkor wat. It is situated in combodia and spread across over 400 acres / 1.6 km².

It was listed as a UNESCO World Heritage Site in 1992, which encouraged an international effort to save the complex.
It was originally built as a Hindu temple dedicated to the god Vishnu. In Khmer, the Cambodian language, Angkor means "city" and Wat means "temple grounds".

So Angkor Wat means "Temple City". Its original name was Vrah Vishnuloka or Parama Vishnuloka, meaning the sacred dwelling of Vishnu in Sanskrit.
But, it gradually turned into a Buddhist temple towards the end of the 12th century & is still used for worship today.

Angkor Wat was initially designed and constructed in the first half of the 12th century, during the reign of Suryavarman II, as the king’s state temple and capital city. It was built without the aid of any machinery, as there was no machinery available at that time.

Evidence for these dates comes in part from inscriptions, which are vague, but also from the architectural design and artistic style of the temple and its associated sculptures.

Another aspect is that the five central towers of Angkor Wat symbolize the peaks of Mount Meru,
