In light of this serious cyber attack and this being the second in a row that I've heard in the past few weeks, I'd like to take this moment to talk about the cyber attack known as #phishing so that others do not fall prey to it and stay safe online.

Thread starts:

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.

FB POST BY MR PRABEER BASU,

" Received a hurtful post from an old friend and colleague. He was on my daily Broadcast list of WhatsApp. He requested that I do not send him any of my posts on 'political' issues. I gave him a long explaination

on why I write and what I write. But he was not convinced.

Being alerted by him thus, I felt I should clarify to all who read my posts on what exactly I think and do.

The charge against me is that I wrongly support our current Prime Minister, Shri Narendra Modi..

and that it establishes I am not rational and impartial anymore.
Let me try and explain.First and foremost,I do not write on 'political' issues. I write on 'national' issues. For example, I have no opinion on whether Rahul Gandhi should be President of his party or not.

Similarly, I have no views whether BJP is a better party than Congress or vice versa.
Even after 36 years in the IAS I have no MLA, MP or anyone involved in politics whom I can classify as my friend or even acquaintance.

So, naturally I don't care which party wins or loses as long as the winning party runs an honest government doing good to my nation.
Now, why I speak in favour of Shri Modi:

1. Ever since the beginning of my service I realised that Planning Commission was not serving..

The Haas / Force India argument is fascinating, and the decision of the stewards may still have consequences. The first key finding is that the stewards ruled Racing Point Force India to be a valid constructor. That means that it builds its own cars.

Haas had argued that the cars had been designed by Force India, but as Haas knows only too well, "outsourcing" is legal. The stewards decided that "there is no regulatory support for the argument that Outsourcing of Listed Parts cannot come from a former or excluded team."

In determining this, the stewards also came to the following conclusion: "In relation to the submission by the Racing Point Force India F1 Team that it is not a new team, the Stewards decide that the Racing Point Force India F1 Team is indeed a new team."

This will have a big knock on effect for Haas in its continued arguments over the rights of RPFI as relates to its eligibility and rights under the complex payments structure. Haas has argued all along that RPFI should be treated as a new team and tread the same path that it did.

TLDR? Haas lost the fight but may have won the war. In having its argument that Racing Point hadn't designed their own car thrown out, they gained clarification that RPFI was a new team.

Starting my 2nd thread on Sringeri Parampara. This will cover the Jagadgurus after Sri Vidyaranya to Sri Shivabhinava Nrisimha Bharati.

It is really very tough to match the brilliance and achievements of Vidyaranya. After whom came 15 - Chandrashekara Bharati [1386-1389].

The next Acharya was Nrisimha Bharati [1389-1408]. Harihara raya found a town for this Acharya - Narasimhapuram. Acharya helped the king by guiding him in political affairs. He also initiated the kind with mahamantras for spiritual development.

Subsequent Acharyas were
15-Puroshottama Bharati [1408 - 1448]
16-Shankara Bharati[1448 - 1455]
17-Chandrasekhara Bharati II [1455 - 1464]
18- Nrisimha Bharati II [1464 - 1479]
19-Puroshottama Bharati II [1479 - 1517]

20-Ramachandra Bharati [1517 - 1560]. Sadashiva Raya was emporer of Vijayanagara during this time.
21-Nrisimha Bharati III [1560 - 1573]
22-Nrisimha Bharati IV [1573 - 1576]
23-Nrisimha Bharati V [1576 - 1600]

24-Abhinava Nrisimha Bharati [1600-1623]. When he visited Malahanikareswara temple for first time he noticed there was no Vinayaka there so he took piece of turmeric and drew outline of Ganesha on a pillar and offered puja.

Surkanda devi mandir is a famous shrine of Hindus located near Kaddukhal distt of Uttarakhand, 11 Km from the town of Dhanaulti and 35 Km from Mussoorie.
The Temple is one of the 51 Shakti Peethas spread all over Indian Subcontinent and is dedicated to Goddess Surkanda.

Nestled on a Hill at an Altitude of 2700 m approx, the place offers a splendid view of the snow capped mountains, the picturesque scenic beauty that offers an experience of the lifetime.
The Temple build in the traditional Garhwal style exuberates the Architectural splendour.

The origins of the Surkanda Mata Mandir is attributed to Goddess Sati, consort of Bhagwan Shiv who in a rage immolated herself in her arrogant Father Daksha's Yajna Kund bcoz he didn't invite Bhagwan Shiv in the Yajna.

Devastated by the death of Sati Shiva wandered all over the cosmos performing Tandava-The Dance of Cosmic Destruction.Fearing the total annihilation of cosmos, Gods requested Bhagwan Vishnu to pacify Shiva.Bhagwan Vishnu then used his discuss to destroy the burning corps of Sati.

The pieces of Sati Mata's body then got scattered all over the region which were later established as Shakti Peethas by Bhagwan Shiva himself.Its believed that the head of Sati fell here and it was called Sirkhanda Mata Temple before, but with passage of time it became Surkanda.
