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.

I got a Toshiba T1200, which has a bad screen, and a dead CMOS battery, and I thought the hard drive was broken too...

but I rebooted it and heard a KTHUNK and a really loud spin-up noise and holy shit, the hard drive works!

and it still has files on it. the newest date is January 1994.

It's a 21mb hard drive, with ~37k of bad sectors.

This fucker is never going to spin up again, so I better go find some serial cables and copy shit off now.

The backlight is fucked so I'm shining a flashlight on it.
without it, it looks like this.

Remembering Colonel Anil Kaul, VrC (Retd) on his 3rd Death Anniversary.

“It was October 12, 1987, exactly 5:55 pm as I was… coming out of the cupola of my T-72 tank on a steamy evening in an unknown place called Kokkuvil in the Jaffna district of Northern Sri Lanka.+

I froze in that confined space at what I saw. An LTTE militant stood at 60 meters aiming his rocket-propelled gun at my tank.

In a flash he fired. Probably having lost his nerve he aimed too low. The projectile hit the left mudguard of the tank, but for some inexplicable reason+

did not explode. It then hit the side of the main gun and then exploded on top of the turret, all in a fraction of a second. Before I knew, it seemed I had received a straight right punch so to say to my chin. I saw some blood appear on my left hand and there was a sharp drop in+

my eyesight.

Lt Colonel (now Lt Gen) Dalbir Singh, then Commanding Officer of 10 Para Commando, who was standing on the engine deck said to me, “Yaar what a close shave.”

He suddenly saw me and the look on his face told me that something was very very wrong with me. In that+

fraction of a second, as if it was a rewind of my entire life, thoughts raced through my life as to how and when I had landed myself in such a situation…

I asked my gunner to pull out a first field dressing (FFD) which is standard equipment in a first aid box carried in each+

IMPORTANCE OF SATYA NARAYAN KATHA AND ITS ORIGIN.

We all have heard and read the Satyanarayan katha. But none of us dont know the original stories that Shatanand or Sadhu or Kalavati must have heard. Also, as a habit we hear or read this katha

but dont know the proper way it should be conducted.

We find its mention in Skanda puraan(Reva khand) and Bhavishya Puraan(Pratisarg parva).
Both Bhagwatam and Gita call Bhagwan Narayan as Satv or Truth. So Satyanarayan denotes this name as the one which is Truth incarnate.

The story began in Naimisharanya when Vyasji asked Sutji about a way to eliminate all the sorrows and fulfill all the desires and about who is the devta who can grant these at the same time.

So Suutji first prayed to Bhagwan Satyanarayan who is no one else but Vishnu ji.

Then he remembered all his avatars.After that he narrated the story of Narad. Once while visiting Mrityulok, Naradji was pained to see the sufferings of People around. He was deeply moved by these sufferings and wanted to know the means by which we could rid ourselves from these.

So he went to Vishnu ji and after paying his respects stood in front of him. Naradji narrated the purpose of his visit.

So Bhagwan Vishnu said to him that in Satyug and Tretayug, Bhagwan eliminates sorrow in Vishnuswarup. In Dwapar he assumes different forms to help people.

AHOBILAM NARASIMHA SWAMY KSHETRAM: KURNOOL (AP)
#andhratemples

Ahobilam is the place where Prabhu appears in his fierce form, called Ugra Narasimha, who is Svayambhu (self-manifest).
Ahobilam is one of the 108 Divya Desams. It has 9 shrines for different forms of Narsimha.

Ahobilam was the exact place where Sri Narasimha appeared and tore apart Hiranyakashipu to save Prahlad. At that moment, all the Devas appeared and praised him as Ahobala (Aho is mighty and bala is strength). So the place came to be called Ahobilam.

Out of the 9 shrines, most famous is the Ahobila Narasimha Swamy where Prabhu is seen as Ugra Narasimha.
In another shrine, Prabhu appears as Malola Narasimha Swamy. Malola means beloved of Lakshmi. Here Prabhu is in peaceful mudra with his consort Ma ChenchuLakshmi.

Jwala Narasimha Swamy shrine is the actual spot where the fierce anger of Prabhu reached its culmination when he tore Hiranyakasipu.

Ugra Stambham is the pillar from which Narasimha appeared with such force that the entire hill split into two.
