Credit Suisse and Deutsche Bank are on the verge of collapse.

A thread on the ongoing crisis at DB and CS as per my limited understanding. 🧵

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.

@ChenHuailun here. I'm adding a supplementary thread before today's scheduled one to expand on the origins and early history of the Church of the East (aka the Nestorian Church) ~ahc #jingjiao 1/

The Church of the East traces its origins to the christological position of the School of Antioch, which held that the human and divine and human essences (ουσία) of Christ were united in a single prosopon (πρόσωπον). ~ahc #jingjiao 2/

This ran against the position of the School of Alexandria, which held that the two essences of Christ were united in a single hypostasis (ὑπόστασις). In general terms, hypostasis is more inherent than prosopon. ~ahc #jingjiao 3/

One implication of the Antiochene rejection of the hypostatic union is that Mary could not accurately be called the Theotokos, or God-bearer. Instead, she is the Christotokos, the Christ-bearer. ~ahc #jingjiao 4/

These Christological debates were further complicated by Syriac terms such as 'kyana' (ܟܝܢܐ), associated with 'ousia' but later translated to 'hypostasis' by Syrian Orthodox; and 'qnoma ' (ܩܢܘܡܐ), sometimes contentiously translated as 'hypostasis' or 'person.' ~ahc #jingjiao 5/

SRI KUMARIAMMAN, KANYAKUMARI (TN)
#bharatmandir #navratri2021

Created by Maharshi Parasurama and also one among the 108 Shakthi Peethas in the world. The name Kanyakumari stands for Kanya(Virgin) and Kumari(girl).
Devi took this form to vanquish the demon Banasura
@GunduHuDuGa

Once, Banasura(grand son of Mahabali) obtained a boon from Shiva that he could be vanquished only by a virgin.
So, Devi took the form of a kumari and started meditating with the desire to marry Shiva at Suchindram.
Pleased Shiva fixed the midnight hour for marriage with Devi.

Devarshi Narada knew that the marriage would end the chance of killing Banasura. So, he assumed the form of a cock and crowed. Shiva returned back to Suchindram thinking that it was dawn.
Angered, Devi cursed that all food and articles meant for wedding turn into sand and shells

When Banasura heard about Devi’s beauty, he tried to take her by force. Devi, then, killed him and granted the wish of Devas to remain there always protecting them.
The murti of Devi stands with a rosary in hand. Her diamond nose-ring is said to be visible even from the sea.

Once an ancient mariner mistook it for a lighthouse and sailing towards it, his ship wrecked upon the Kanya Kumari rocks. In order to prevent such a tragedy from happening again, the eastern door of the shrine is opened only on five special occasions throughout the year.
