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.

WEAPONS OF MAHADEV

Sarvaripati Shiva is one of the most fearsome manifestations of Mahadev. Assigned with destroying all of the universes at the end of time, Shiva is one of the most fearsome warriors. He is the Mrityunjaya.
Here are some weapons associated with him:

TRISHULA: the 3 pointed blades denote creation, maintenance, and destruction or the 3 Kalas – Past, Present and Future. They also represent 3 Gunas – Sattva, Rajas and Tamas).
Shiva’s trishul can only be stopped by Shiva himself.

Trishul is also said to represent Ida, Pingala, and Sushumna. These are the three basic nadis – the left, the right and the central – in the pranamaya kosha, or the energy body of the human system.

PARASHU: axe with 4 cutting edges which Shiva gave to Parashurama. In his anger, Parashurama used the parashu to get rid of the all the Earth’s tyrannical kshatriya caste twenty-one times over.

CHANDRAHASA SWORD: The divine sword Chandrahasa literally means ‘the laughter of the moon’. Ravana gave this sword to Indrajit on different occasions especially to fight against Devas.
GIRISH: A special sword of Shiva with unique characteristics.

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.

They’re shooting into the chamber.
