What is it?

Putting ML in Production: a guide and code-driven case study on MLOps. We will be developing and deploying Made With ML's first ML service, from Product → ML → Production, with open source tools.

This ML service will act as a foundation for all future ML features and subsequent iterations. The first feature is tagifai - multilabel classification of tags for a project. We'll discuss the need and utility of this feature in the first lesson.

Who is this course for?

- ML developers looking to become end-to-end ML developers.
- Software engineers looking to learn how to responsibly deploy and monitor ML systems.
- Product managers who want to have a comprehensive understanding of the different stages of ML dev.

Tired of word clouds? Want to do better sentiment analysis? Not sure how to look at the words underneath your measures?

Our long overdue paper on generalized word shift graphs is finally here!
https://t.co/lIBXvbMJWX
https://t.co/vSL1REYT8V

So what are they?

1/n

If we have two texts, there are many ways we can compare them. Weighted averages are a particularly useful measure because they're flexible and interpretable

Proportions, Shannon entropy, the KLD, the JSD, and dictionary methods can all be written as weighted averages

2/n

But weighted avgs are also slippery. When we try to compress complex phenomena like happiness, surprise, divergence, or diversity into a single number, it can be unclear what we're measuring

If the measure goes up, what does that mean? Why did it do that? Can we trust it?

3/n

Very often, that's the end of the line and we're left with an uneasy feeling in the pit of our stomach that our weighted avg is actually picking up a data artifact or some other unintended peculiarity

Word shift graphs help us address those concerns

4/n

First, word shifts look under the hood of weighted averages to see what's going on

All weighted averages are a sum of contributions from individual words. We can pull out those words, and rank which ones contribute the most to the difference between two texts

5/n

An amazing new project from @bearpelican was just released: https://t.co/DBov6sZTVS . A beautiful design; you can auto-generate a melody from chords, chords from a melody, and more.

It's technically brilliant, combining BERT, seq2seq, and Transformer XL
https://t.co/jF3mO5aXiu

It's also a wonderful example of leveraging and customizing the fastai framework in a deep & thoughtful way.

On Bayesianism, the Many Worlds Interpretation, and personal identity.

Some thoughts worked out in a letter to a friend, which is the kind of thing you do when off Twitter for a glorious week. (🧵)

“Chance is ignorance”—the Bayesian story; all probabilities represent states of mind, not states of the world. One *could* put (some) chances “in the world”, but let’s take Occam’s Razor seriously...

That the probability of a fair coin coming up heads is 50% simply means that marginalizing (tracing, as the physicists say) over the hidden facts leaves you, nearly, maximally ignorant of the outcome.

Quantum uncertainty (access below!) poses an apparent challenge to this story. There seems to be nothing to be ignorant about when it comes to (say) electron spin—there is nothing “inside” the

The electron is a simple object, in other words. So where does the uncertainty come from? One could follow David Wallace’s wonderful interpretation in terms of chaotic dynamics and decoherence, but let’s see if we can take another route...

Thrikkangode Sree Randu Moorthy Temple
Ottappalam, Kerala. 🚩
#keralatemples

This is very unique temple as Shiva and Vishnu both are in the “linga” form in the same Garbhagriham. The Srikovil is in a circular pattern. Temple's Prathishta was done by Parasurama.

Mahadeva and Maha Vishnu in the same Srikovil is very rare Prathishta, but poojas are done separately Dhara is done to Maha Vishnu here. People suffering from “KAIVISHAM” and mental illness are fully cured on drinking a medicinal herb supplied by a nearby family here.

The root of the banyan tree around the Ayyappa Sannidhanam is said to have great powers for skin ailments.

Very ancient temple but was covered with forest for many years.
Later two persons Chakki and Chaathan, while cutting trees their axe hit on the nearby
@SriramKannan77

Vigrahams and it suddenly started bleeding. Later Devaprashnam was held and thus found out that these were murthy's of Shiva and Vishnu which was worshipped long back. And thus temple is constructed here.

1/ there is this sense when you are young that your accomplishments need to be a list of things that seem impressive to others. A list of several items you did.

This isn't actually right, so here is another suggestion.

2/ I remember being 26 and writing about reading 52 books a year. I wrote blog posts about it. They got copied. It became "a thing." Now it's in Twitter bios. It looks impressive but it's insanely useless and I shouldn't have done it.

3/ what I should have known at that time is that only young idiots like myself, with no accomplishments, find list of tiny achievements impressive. Anyone who has actually done anything of substance doesn't gaf

4/ what is actually difficult, and worthwhile, instead is to do ONE single thing for a very, very long time. It's much harder and much rarer and results in outlier outcomes much more often.

Of course you can find this out too late if you are chasing the dragon of Ted talks etc

5/ if I had only worked on a startup for a year, I would've gotten nowhere, the same way that if you lift for 3 months, it achieves nothing. Everything good in life comes from perseverance, but at the beginning, you're just like "I need to be somebody!!!"

Sri Mridanga Saileswari Temple Muzhakkunnu, Kannur KERALA

The temple is established by Parasurama and it is one among 108 Durga temples.
Devi will answer all the prayers of her devotees who pray to her with utmost devotion lighting the ghee deepam.

It is the family diety of Kerala Varma Pazhassi Raja.
Devi is present in three forms Kali, Saraswati and Lakshmi.

Legend...👇
Once a Mridungam ( musical instrument) shaped rock fell from heaven here.
@SriramKannan77

Devi originated in the form of Mridangam and Parasurama captivated the essence of Devi into a Vigraham. Vigraham is made of Panchaloham.
Kathakali, an art form of Kerala originated here.

Temple Vigraham was stolen 3-4 times, but because of power of Devi all the attempts were failure. Police records says that Whenever the thieves try to steal, they lose their senses, and they will be in a confused state. So they will abandon the idol.

Trump on climate: I don't believe it. Trump on Khashoggi: I don't believe it. Trump on Russia: I don't believe it. Idiocy? A canny game? Doesn't really matter as much as the underlying intellectual autocracy. In this administration only one opinion matters.

It's an assault on facts and reason. It's an assault on good governance. It's an assault on the bureaucracies that are being discounted. It's an assault on science and history. But it is also an assault on one of the underpinnings of democracy.

We live in a system that is grounded on the idea of collaborative government. Leaders may have a final word but even then, there are typically checks and balances. Hopefully, in this case, such checks and balances may work. But they also are being tested.

The president's position that he is smarter than all the world's scientists, than the entire intelligence community, than experts who have studied any issue all their lives, is, of course, asinine. But his belief that government turns solely on his opinion, is monarchic.

Louis XIV reportedly said, "L'etat est moi." That he was the state. Trump asserting that he knows better than all, discounts all advice, that his brain is enough to chart the course for America alone, is essentially saying the same thing.

SRI KANTESH HANUMANTHA, KADARAMANDALAGI (KAR)
#bharatmandir

KANTESHA means Prabhu full of brightness.
Here, Sri Hanuman appears with a front face and sparkling eyes. Earlier, the village was also called KANTESHPURI on the name of Kantesha Hanuman.

Several thousands of years ago, Hanuman lived in this village. He once saw the Sun and mistaking it to be a fruit, began flying towards it. Since then, this village came to be known as Kadara Man Dalagi. (Kadar means rays, mandala is cluster of rays).

It is believed that King Janmejaya had set up the shrine to get rid of his difficulties.
There is a small pond on the right side of the kshetram where Teppotsava (Float festival) is celebrated.

Kanaka Dasa has praised Sri Kantesha in his various poetic compositions.

Kanaka Dasa was the first devotee to popularize the power of Kantesha. It is said that once Kanaka Dasa was deeply wounded in a battle. To seek blessings, he visited Tirupati but Sri Venkatesha appeared in his dream and advised him to see Kantesha first before seeing him.
