An introduction to one of the the most basic structures used in machine learning: a tensor.

🧵👇

Tensors are the data structure used by machine learning systems, and getting to know them is an essential skill you should build early on.

A tensor is a container for numerical data. It is the way we store the information that we'll use within our system.

(2 / 16)

Three primary attributes define a tensor:

▫️ Its rank
▫️ Its shape
▫️ Its data type

(3 / 16)

The rank of a tensor refers to the tensor's number of axes.

Examples:

▫️ The rank of a matrix is 2 because it has two axes.
▫️ The rank of a vector is 1 because it has a single axis.

(4 / 16)

The shape of a tensor describes the number of dimensions along each axis.

Example:

▫️ A square matrix may have (3, 3) dimensions.
▫️ A tensor of rank 3 may have (2, 5, 7) dimensions.

Machine learning education is broken.

If you are preparing for a research position, you are good. If you are looking to get out there and start solving problems, not even close.

Here are some thoughts so you can get ahead.

↓

Most classes, courses, and books cover the same road.

They start with a dataset. They finish with a working model. The focus is always on everything that happens in between.

Dataset → Model.

This is great, but not enough.

Real-life situations rarely start with a dataset, and they never end after you finish building your model.

Applying machine learning successfully is hard.

Here are a few examples that you should keep in mind.

First challenge: Properly framing up the problem.

If you don't understand the problem, you can't determine what data you need. If you don't understand the data, you can't build a good model.

I've never seen a company that had their data ready to go.

In fact, most of them don't even have data at all and need you to determine what exactly they should start collecting.

You usually have to go Problem → Potential Solution → Data.

10 machine learning questions you should be able to answer.

I started experimenting with a questionnaire before interviewing candidates. Applicants submit a video or written answers to apply for the position.

Thread: Let's look at 10 of these questions.

The questionnaire solves a couple of problems:

1. Weeds out candidates that aren't ready for the job.

2. It significantly cuts down the time we spend talking synchronously.

One problem: It requires extra time from the candidate before the phone interview.

Here are some numbers on a job posting before using the questionnaire:

• 249 applicants
• 13 good applications

That's only 5%.

This sucks.

Numbers after using the questionnaire:

• 44 applicants
• 21 good applications

That's 47%.

This is much better.

I look at it this way:

Sooner or later, I'll ask these questions, and the candidate will have to answer them.

I'd rather give them space and the opportunity to think about their answers without any pressure.

Those who can't or don't want to answer won't apply. That's fine.

What's machine learning?

Not a framework. Not a different language. Not the latest "cool" thing around the Internet.

Thread: Let me convince you that machine learning is the best thing since sliced bread 🍞.

Let's start with a simple exercise:

"Write a function that returns 0 if a supplied number is even or 1 if the number is odd."

If you are a developer, I'm sure you know how to write this function. It should be simple, right?

To avoid using a specific syntax, let's represent this function as follows:

y = f(X)

Where:
• X → The input number
• y → The result (0 if even, 1 otherwise)
• f → The function that does the work

We can now get to the interesting part.

If you are a programmer, writing this function is simple.

You know the relationship between X (the input number) and y (the output), so you can easily write the rules (the function.)

In machine learning, we don't write the rules. We learn them.

Imagine we had an algorithm that processes many samples (X → y), learns the relationship between them, and comes up with the correct rules.

We call these samples "training data," and they would like like this:

• 2 → 0
• 5 → 1
• 8 → 0
• 4 → 0
• 3 → 1
• ...

My highlighted passages from The Psychology of Money by @morganhousel. Thread below

1. The 401k - the backbone savings vehicle of American retirement - did not exist until 1978. The Roth Ira was not born until 1998. If it were a person it would be barely old enough to drink

2. NYU professor Scott Galloway has a related idea that is so important to remember when judging success - both your own and others': "Nothing is as good or as bad as it seems."

3. Margin of safety - you can call it room for error or redundancy

4. "Every job looks easy when you're not the one doing it because the challenges faced by someone in the arena are often invisible to those in the crowd."

5. "The average equity fund investor underperformed the funds they invested in by half a percent per year, according to Morningstar - the result of buying and selling when they should have just bought and held."

Too much intellect without a sense of self can inflate your ego.

This is why a lot of high IQ people lack social intelligence.

They talk to humans like robots & are baffled when they are resented for it.

This is why the charismatic person who knows less often rises up quicker

'What you smoking bro?? My IQ will be the biggest factor of my success!'

Incorrect.

That's a limiting belief.

I'm gonna shake up your paradigm real quick 👇

You have been conditioned your entire life to believe that IQ score alone will dictate success.

And like most people, we were like 'yea, sure!'

But there's few incorrect thought patterns here

1. Success is subjective.

2. IQ exam insinuates intellect is fixed.

3. Your high IQ won't make others give a fuck, your communication will.

Let's go thru each one

1. Success is subjective

What I consider success may not be success for you.

Success it's a mirror image of where you are & where you want to be.

Aka sense of self.

So measuring success starts from looking within, not an exam.

👨‍💻 Last resume I sent to a startup one year ago, sharing with you to get ideas:

- Forget what you don't have, make your strength bold
- Pick one work experience and explain what you did in detail w/ bullet points
- Write it towards the role you apply
- Give social proof

/thread

"But I got no work experience..."

Make a open source lib, make a small side project for yourself, do freelance work, ask friends to work with them, no friends? Find friends on Github, and Twitter.

Bonus points:

- Show you care about the company: I used the company's brand font and gradient for in the resume for my name and "Thank You" note.
- Don't list 15 things and libraries you worked with, pick the most related ones to the role you're applying.
-🙅‍♂️"copy cover letter"

"I got no firends, no work"

One practical way is to reach out to conferences and offer to make their website for free. But make sure to do it good. You'll get:

- a project for portfolio
- new friends
- work experience
- learnt new stuff
- new thing for Twitter bio

If you don't even have the skills yet, why not try your chance for @LambdaSchool? No? @freeCodeCamp. Still not? Pick something from here and learn https://t.co/7NPS1zbLTi
You'll feel very overwhelmed, no escape, just acknowledge it and keep pushing.

Let’s talk about hope & despair.

[THREAD]

Crank this up for the

1/ One of the more memorable—and frightening—lines from “Nineteen Eighty-Four” reads: “If you want a picture of the future, imagine a boot stamping on a human face— forever.” In Orwell’s dystopia, resistance is futile. Big Brother wins, inevitably.

2/ I refuse to believe this applies to the USA in 2021. I won’t have it. I don’t care how much dirty money mobster spy psy-op disinformation data manipulation corporate MAGA Christofascist QAnon Fox News weapons these fuckers have in their arsenal. WE shall prevail. Not them.

3/ Is this second impeachment infuriating? Yes. Are Trump’s lawyers and his GOP lickspittles gaslighting us yet again? Yes. Does that mean that all hope is lost? Hell no.

4/ I’m hearing this w/r/t impeachment: “’Mueller is coming’ didn’t work out so well.” Can we parse that for a minute? Yes, we wanted Mueller to arrest ALL of them, and he didn’t—because he couldn’t. Rosenstein didn’t allow him to follow the money. Barr cockblocked the Report.

4 Sure Fire Habits You Must Develop to Become Successful.

I define success as a series of habits that you build and abide by to create your own reality.

Practicing these simple habits will surely make you successful, no fluff.

1. Focus on the things that matter - intently focus on what is essential for you and your goals. Block out distracting information, ideas and opinions.

Always ask in the course of the day,

"Is whatever I'm doing important?"

2. Empower others - one thing remains true than ever. Good leaders set themselves apart by effectively influencing and empowering those around them.

This is how great leaders shine with heroic display of empathy and compassion when others are down.

3. Delegate your weaknesses - There's someone who is strong at your weakness. They will do what you can't more efficiently at a cost.

This gives you enough time to build on your strengths.

Have a team that will work for a common course.

How to sell option?
Here let me explain through simple math.
Say BN at 30000
30000 straddle trading at combine premium 800 ( based on current volatility)
Put at 400
Call at 400
You don’t know direction. Sold both.

If move will not come than both will decrease gradually.

At day end it will come down to 720-740 if move will not come. Difference is your profit.

Now case 2:
Move started.
At one points combine premium will start increasing.
Say 810.
Exit immediately. No need to do adjustment.
Let market settle.

Sell again straddle once market settle.
Now repeat same thing.

Straddle selling webinar over.
Good luck.

One can keep SL 550 for both strike to escape from sudden movement.

SRI BANASHANKARI AMMAN, BANGALORE
#bharatmandir

Located in Southern Bangalore, this is one of the most popular places of worship in Bangalore City.
Devoted to Devi Banashankari, this shrine is visited specially during Rahukala which is believed to be an unfavorable time.

Somanna Shetty, a great devotee of Devi, brought this murti from Badami’s Banshankari Amma Kshetram.
It is said that many years ago, three ladies visited this shrine and requested the pujari to conduct puja for them. Since it was the inauspicious rahu kaal, the pujari refused.

However, upon their insistence, he conducted the puja. When he returned with prasadam, the ladies vanished. This made the people believe that they were none other than the Devi herself. Since then, the people perform poojas here during the Rahukaal.
@GunduHuDuGa

People use lemons as a diya. Lemons are cut from the centre and their pulps are removed, for pouring oil in them.
It is strongly believed that Devi removes all the troubles from the life of her devotees during the Rahukala although it is considered inauspicious for any pooja.

I'm going to do two history threads on Ethiopia, one on its ancient history, one on its modern story (1800 to today). 🇪🇹

I'll begin with the ancient history ... and it goes way back. Because modern humans - and before that, the ancestors of humans - almost certainly originated in Ethiopia. 🇪🇹 (sub-thread):

The famous \u201cLucy\u201d, an early ancestor of modern humans (Australopithecus) that lived 3.2 million years ago, and was discovered in 1974 in Ethiopia, displayed in the national museum in Addis Ababa \U0001f1ea\U0001f1f9 pic.twitter.com/N3oWqk1SW2
— Patrick Chovanec (@prchovanec) November 9, 2018

The first likely historical reference to Ethiopia is ancient Egyptian records of trade expeditions to the "Land of Punt" in search of gold, ebony, ivory, incense, and wild animals, starting in c 2500 BC 🇪🇹

Ethiopians themselves believe that the Queen of Sheba, who visited Israel's King Solomon in the Bible (c 950 BC), came from Ethiopia (not Yemen, as others believe). Here she is meeting Solomon in a stain-glassed window in Addis Ababa's Holy Trinity Church. 🇪🇹

References to the Queen of Sheba are everywhere in Ethiopia. The national airline's frequent flier miles are even called "ShebaMiles". 🇪🇹

SRI CHAMPAKADHAMA SWAMY, BANNERGHATTA HILL, BENGALURU (KAR)
#bharatmandir

The shrine is dedicated to Sri Vishnu along with Devi Lakshmi and Bhoodevi.
It is built in an area full of Champaka trees.
As champaka flowers are offered to Sri Vishnu here, it is called Champakadhama.

It is believed that King Janmejaya had sarpa-dosha. To get rid of it, he took bath in the nearby pond. He emerged with a golden body and sarpa-dosha was also removed. The pond is called Swarnamukhi and believed to have curative powers.
Sri Vishnu murti was consecrated by him.

It is also believed that this forest area was the Dandakaranya where Sri Ram stayed in exile.
Some believe that the original shrine was built by Pandavas.
The pushkarni/pond is emptied once a year so that the rock at the bottom (which has image of Anjaneya) may be worshipped.

MEENAKSHI AMMAN, MADURAI (TN)
#bharatmandir #navratri2021

A paadal Petra sthalam where Shiva took the form of Sundareswarar (the handsome one) and married Devi Parvati (Meenakshi).
Devi is also known by the name Angayarkanni (mother with the beautiful fish eyes).
@GunduHuDuGa

Devi Meenakshi emerged from yagna fire as a 3 year old girl when Pandyan King Malayadwaja and Kanchanamalai were praying for a child.
It is said that Devi was born with three breasts and there was a prophesy that her superfluous breast would melt away when she met her husband.

Devi ruled over Madurai and captured Indralok. She went on to capture Kailasha. When she saw Shiva, her 3rd breast disappeared and she realised that Shiva would be her consort.
The divine marriage was attended by all Devas and Sri Vishnu (as her brother) gave her hand to Shiva.

It is said that Indra found a swayambhu lingam at Kadamba Vanam. He placed it in Madurai where the kshetram stands. Here, Shiva is seen on the vehicle of Indra.
The Golden Lotus Tank is said to be the place where a golden lotus blossomed for the puja performed by Indra.

The Meenakshi Thirukalyanam festival is celebrated in the Chithirai month to mark the divine marriage of Meenakshi Amman. The festival includes a procession where Meenakshi and Sundareshwara travel in a chariot and Sri Vishnu gives away his sister in marriage to Shiva.
