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.

Here is a simple example of a machine learning model.

I put it together a long time ago, and it was very helpful! I sliced it apart a thousand times until things started to make sense.

It's TensorFlow and Keras.

If you are starting out, this may be a good puzzle to solve.

The goal of this model is to learn to multiply one-digit

It is a good example of coding, what is the model?

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
• ...

11 ways ChatGPT saves me hours of work every day, and why you'll never outcompete those who use AI effectively.

A list for those who write code:

1 of 16

1. Explaining code

Take some code you want to understand and ask ChatGPT to explain it.

I've found explanations are very detailed. This is much quicker than trying to figure out convoluted code.

2 of 16

2. Improve existing code

Ask ChatGPT to improve existing code by describing what you want to accomplish.

It will give you instructions about how to do it, including the modified code.

3 of 16

3. Rewriting code using the correct style

This is great when refactoring code written by non-native Python developers who used a different naming convention.

Notice how ChatGPT not only gives you the updated code; it also explains the reason for the changes.

4 of 16

4. Rewriting code using idiomatic constructs

Very helpful when reviewing and refactoring code written by non-native Python developers.

ChatGPT knows the "Pythonic" way, and it will give you suggestions to improve your code and make it much more readable.

The Law of Trust

“I’m not upset that you lied to me. I’m upset that from now on I can’t believe in you”- Friedrich Nietzsche

Sometimes in October, I received a call from a former client who had been out of the country for almost a year.

He is not a Nigerian but had just secured an appointment with a company. His first statement was “Bayo, I need to pick your brain on this because with you I know where I stand. I know you’ll not deceive me”.

After our discussion, he told me he had already informed his Chairman that their banking relationship had to come to me. I’ve signed it on since.

I’ve had cause to reflect over his statement many times since then. Here was a man whom sometimes I had very difficult conversations with. I’ve had to tell him no when I knew his requests were not possible. Sometimes, the relationship was stormy.

I never fail to tell my colleagues that the major currency for transaction is integrity and this will only be sustained in an atmosphere of trust. Never lie to customers in order to make a sale.

1/“What would need to be true for you to….X”

Why is this the most powerful question you can ask when attempting to reach an agreement with another human being or organization?

A thread, co-written by @deanmbrody:

Next level tactic when closing a sale, candidate, or investment:

Ask: \u201cWhat needs to be true for you to be all in?\u201d

You'll usually get an explicit answer that you might not get otherwise. It also holds them accountable once the thing they need becomes true.
— Erik Torenberg (@eriktorenberg) February 27, 2018

2/ First, “X” could be lots of things. Examples: What would need to be true for you to

- “Feel it's in our best interest for me to be CMO"
- “Feel that we’re in a good place as a company”
- “Feel that we’re on the same page”
- “Feel that we both got what we wanted from this deal

3/ Normally, we aren’t that direct. Example from startup/VC land:

Founders leave VC meetings thinking that every VC will invest, but they rarely do.

Worse over, the founders don’t know what they need to do in order to be fundable.

4/ So why should you ask the magic Q?

To get clarity.

You want to know where you stand, and what it takes to get what you want in a way that also gets them what they want.

It also holds them (mentally) accountable once the thing they need becomes true.

5/ Staying in the context of soliciting investors, the question is “what would need to be true for you to want to invest (or partner with us on this journey, etc)?”

Multiple responses to this question are likely to deliver a positive result.

10-Life Lessons From The One & Only @naval

~Thread~

“You want to be rich & anonymous... Not poor & famous.”

The goal is to get rich & disappear, not to get noticed!

The problem is that too many people are chasing clout instead of wealth.

Clout is not gonna put food on the table in 5 years. Change your priorities!

“I don’t have time” is just another way of saying, “it’s not a priority”

Being “Too busy” is a myth,

People make time for the things that are important to them.

If you haven’t made enough time then it’s simply because you haven’t convinced yourself it’s a priority.

“Earn with your mind, not with your time”

You’ll never get rich trading your time for money...

Reason being? Because you only have 24 hours in a day & you can’t work non-stop.

Use your mind & money to create a product that will generate you money even while you sleep 🥱

“You can escape competition through authenticity... No one can compete with you on being you”

No 2 humans are exactly the same, there’s something that makes each of us unique.

Find what makes you different & capitalize.

Your biggest competitive advantage is your originality!

Do you struggle with "office politics," like when Colleague got a promotion because they seem to have the same hobbies as the boss?

Do you have no idea how to play the game?
Do you recoil at the very word?

Then this thread is for you 👇

First, what exactly is "office politics?"

The definition I'll go with is that it's the actions people take to advance the things they care about in the workplace.

These can be:

1) The company hitting its goals
2) The success of one's projects and initiatives
3) A promotion
4) A plum assignment or leadership role
4) A change in workplace culture, values or process
5) The advancement of a colleague / group of people
6) Personal reputation

If you read this and think, "hmm, this list sounds boring and not at all bad," I agree with you!

Office politics has a negative connotation but is simply another manifestation of humans being complicated and having multiple, sometimes conflicting desires.

Our workplace desires feel more more high-stakes b/c:

1) there is clear hierarchy + power dynamic (ceos, managers, etc)

2) how we perform at work impacts our self-esteem, identity, and ability to sustain ourselves

3) we spend 1/3+ of our waking hours in our workplace

THREAD: Meditations on marriage metaphors in Ruth

The book of Ruth is, of course, a story about a beautiful marriage. But even before the courtship and the wedding and the important genealogy at the end, we find interesting language that is strikingly reminiscent of Genesis 2:24

That important verse reads:

'Therefore a man shall leave [יַֽעֲזָב] his father and his mother and hold fast [וְדָבַ֣ק] to his wife, and they shall become one flesh.'

The verb עזב can be quite strong in force. For example, Joseph leaves behind [וַיַּעֲזֹ֤ב] his garment as he flees from Pharaoh's wife's sexual advances. Countless times, Israel is depicted abandoning the LORD, for example in Judg 2:12 [וַיַּעַזְב֞וּ], and going after other gods.

Likewise, the verb דבק is rather striking. Lot is mortified of disaster overtaking him [תִּדְבָּקַ֥נִי] as he flees from Sodom. Israel is commanded in Deut 10:20 to cling fast [תִדְבָּ֔ק] to the LORD and serve him and swear by his name.

Together they illustrate how radical God designed marriage to be. Marriage is a real severing of family relations in order to form a new, permanent bond with another human being.

Something very similar to this takes places in Ruth's life.

The Story of how Mary Slessor Stopped the killing of Twins but sadly died of Fever.

All you need to know

Retweet to educate someone

Killing new-born twins was common practice in the 19th century among the Ibibio people of Nigeria, but one Scotswoman went to great lengths to put an end to this.

Aberdeen-born Mary Slessor was one of the few missionaries in Africa who learnt the local language, adapted to the native customs and environment and gained the trust of the locals in order to make a truly positive impact.

Her father, a shoe-maker from Buchan, became incapacitated by alcoholism and Mary more or less became the breadwinner for the family.

From the age of 11, she worked as a ‘half-timer’ mill girl in the Baxter Brothers and Co Ltd, spending half the day at a school provided by the mill owners and the other half working for the company

THREAD: 12 Things Everyone Should Know About IQ

1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE

2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less. https://t.co/UqtS1lpw3n

3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N ≈ 4 million)

(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)

4. IQ predicts many important real world outcomes.

For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3

5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)

GHATI SUBRAMANYA, DODDABALLAPURA (KAR)
#bharatmandir

One of the most important place for snake worship.
The murtis of Kartikeya and Narasimha are self-manifested.
There is an anthill which is opposite the shrine. Bhaktas pour milk on it as part of rituals.

Here Subramanya performed penance in the form of snake. He sought protection from Narsimha for Nagas from Sri Vishnu’s vehicle Garuda, known for his dislike towards serpents.
The Pushya Suddha Shasti is one of the biggest festivals here believed to be appearance day of Subramanya

It was in this region where Subramanya vanquished Ghatikasura, the demon. Hence called Ghati Subramanya.
Childless couples visit here to seek blessings for getting a child.
The installation of snake murtis near the shrine is believed to be an auspicious act.

The murti of Karthikeya with a seven headed cobra faces eastwards while Narasimha faces westwards.
To ensure that both are visible to bhaktas at the same time, a huge mirror is placed in the rear in the sanctum sanctorum.

ARULMIGU SRI PARTHASARATHY SWAMY KSHETRAM, CHENNAI (TN)

Divya Desha where Perumal appears with moustache of a Sarathi (charioteer) to conduct Arjun’s Rath in Kurukshetra war.
Here, Venkatkrishna-Parthasarthy is present with his entire family.

He is flanked by Sri Rukmini, Sri Balarama, Satyaki, son Pradyumn and grandson Anirudha.
It is said that on the request of Raja Sumathirajan, Sri Perumal appeared and stayed here as Arjun’s charioteer (Partha-sarathi).

He is without chakra as he had promised not to wield weapons in Mahabharata war.
The face has scars caused by Bhishma’s arrows on Arjun. Prabhu took the arrows on himself to protect Arjun.

The Naivedyam offered here does not have spices. Ghee is used in it to cure Prabhu’s wounds. Sarkarai Pongal is famous here.

It is said that Rishi Bhrigu found Devi Lakshmi (as Vedvalli) in Alli flower in the mandir pushkarini. Later, Sri Ranganatha came here to marry her.
