Do you want to learn the maths for machine learning but don't know where to start?

This thread is for you.
🧵👇

 The guide that you will see below is based on resources that I came across, and some of my experiences over the past 2 years or so.

I use these resources and they will (hopefully) help you in understanding the theoretical aspects of machine learning very well.
Before diving into maths, I suggest first having solid programming skills in Python.

Read this thread for more details👇

https://t.co/sSN3jdxDwK
These are topics of math you'll have to focus on for machine learning👇

- Trigonometry & Algebra

These are the main pre-requisites for other topics on this list.

(There are other pre-requites but these are the most common)
- Linear Algebra

To manipulate and represent data.

- Calculus

To train and optimize your machine learning model, this is very important.
- Statistics

Make "sense" out of the data you have.

- Probability

Make decisions under uncertainty.
These are some of the resources I recommend for learning these topics 👇

Are you planning to learning machine learning this year?

These are the Python frameworks you need to learn as an absolute beginner.

🧵👇

It can be overwhelming seeing all the machine learning frameworks at once and not even knowing what they do.

I made this thread so that your machine learning journey becomes just a little bit easier.

(2 / 11)

This thread will only focus on Python frameworks.

Why?
Because Python is the most common path into machine learning.

( If you have experience with any other language then learning Python will not be difficult at all. )

(3 / 11)

Here's the entire list:

- Pandas
- Numpy
- Matplotlib
- TensorFlow
- PyTorch
- Keras
- Scikit Learn

Let's see what they do.

(4 / 11)

You'll have to interact with csv files or databases on a regular basis to access data in machine learning, pandas helps you do just that.

The cool thing about Pandas is that it actually doesn't change the original data...

You can use many languages for machine learning, why Python?

Because of 2 reasons:
- Comparatively easier to learn than other languages
- Has the biggest and most mature community

This makes Python a no-brainer to learn for machine learning as a beginner.

(3 / 19)

These are the absolute basics which you must know about:

- Basic terminal commands
- Basic arithmetic (+,-,/,*)
- Accepting user input
- For & While loops
- Exception handling
- If-Else statements
- Functions, modules & Imports

(4 / 19)

Then comes the more tougher concepts which you must know about:

- Object oriented programming in Python:Classes, Objects, Methods
- PIP (Pypi)
- List slicing
- String formatting
- Dictionaries & Tuples
- Managing environments
- Dunder methods like __init__

Thanks for this incredibly helpful analysis @dgurdasani1

Two questions. 1/ Does this summarise the AZ published data :
The plan is to extend the time interval for all age groups despite it being largely untested on the over 55yrs, although the full data is not yet published


Do we have the actual numbers of over 55yr olds given a 2nd dose at c12 weeks and the accompanying efficacy data?

Not to mention the efficacy data of the full first dose over that same period?

I’d quite like to know whether I am to be a guinea pig & the ongoing risks to manage

You attached photos of excerpts from a paper. Could you attach the link?

Re Pfizer. As I understand it the most efficacious interval for dosing was investigated at the start of the trial.


Here’s the link to the

I’ve got to say that this way of making and announcing decisions is not inspiring confidence in me and I am very pro vaccination as a matter of principle, not least because my brother caught polio before vaccinations available.

Okay, doing my first baby steps with r2frida (which combines the power of @radareorg and @fridadotre).

Gonna share my progress in this thread (live, so keep calm).

The goal: Runtime inspection of data sent out by TikTok !!before!! it gets encrypted

1/many

First of all, we do not start from zero. I got some prior knowledge from past reversing attempts and want to share some important facts.

TikTok's (log data) encryption is accomplished by a native library. The Android Java code just serves as proxy function to the native function

The decompiled code for the respective native JNI function of an older TikTok version looks something like this, but in this example I use the most current TT version (no statical analysis done, yet)


In case you never reversed native libraries which were build to interface with Android Java layer via JNI, I highly suggest the entry level introduction on the topic by @maddiestone

Before we start, I want to pinpoint some important aspects (which are also covered by Maddie's videos).

1) Unlike raw C-functions, JNI functions like the one showcased above, receive pointers to complex Java objects .

F.e. a function receiving a String on the Java layer...

If there is one thing I have learned it is that people love bullshit. They buy bullshit stories from professional bullshit artists, accept bullshit philosophies, purchase bullshit how-to-books, vote for bullshitting politicians.

At first, I resisted believing this because it is illogical and dumb and frankly, doesn't reflect well on the human race of which I am a member (and thus have long been hopeful that it is more of a distinction than it actually turns out to be.)

But if you actually are interested in facts you begin to notice how little most people care for them. Sometimes it is because they are heard to learn and bullshit is so much more widely and easily available. Sometimes it is because facts make them uncomfortable about themselves.

Sometimes it is because just one tiny fact will upset a whole worldview that has grown as comfortable as an overstuffed chair. (Settling into such worldviews is a lot like settling into chairs like that because the longer you're there and the deeper you sink...

...the harder it is to hoist yourself up and out of your fat-assed intellectual laziness.) But I actually think the reason people have such an appetite for bullshit goes deeper, goes to an aspect of ourselves we just can't accept.

THE EVOLUTION OF OUR NATIONAL FLAG (1857-1947)

The INDIAN NATIONAL FLAG is not just a flag! It's a testimony of patriotism and seamless sacrifice. A symbol representing one of the oldest civilizations on this planet.

Let's hope what happened yesterday never repeats!

(Thread)


After the revolt of 1857, the first Indian flag was designed. The design was based on western heraldic standards with "Union Jack" in the upper-left quadrant and a "Star of India" enclosed in the royal crown in the middle of the right half.(1)


The flag was a symbol of the direct imperial rule in India.(2)

In 1904 the first Indian flag which stood for India's independence from the British was devised. The design was provided by sister Nivedita, an Irish disciple of Swami Vivekananda.(3)


The flag was red and yellow with an image 'Vajra' (weapon of god Indra). The phrase 'Vande Mataram' was written in Bengali on it. The red colour and the yellow colour signified freedom and victory while the symbol of vajra stood for strength.(4)

Sri Gurubhyo Namaha.


After the phenomenon called Sri Chandrasekhara Bharati came another one - Sri Abhinava Vidya Teertha [1954-1989] the 35th Jagadguru. Srinivasa was born on Nov 13, 1917. He was initiated into Sanyasa by Sri Chandrasekhara Bharati in 1931. He was Jagadguru for 35 years.

He was chosen and specifically trained to take over Peetadhipatyam from Sri Mahaswami. He is majorly responsible for the way Sringeri currently is. He built various buildings for devotees, Gajashala, Gooshala etc.

Acharya on conversions:
Once a person approached Sri Acharya that some other religions are trying to convert Hindus and requested Sri AVT to do prevent these conversions.

AVT replied - what do u mean by religion? Religion i.e. mata is related to 'mati' or intellect.
Caste is called 'jAti' which is related to janana or birth.
Ex- breed of a cow. we cannot change its qualities to resemble another breed by changing its name.

#3/thread on Angkor wat

Christianity and islam may be the largest religion of today’s world but Sanatan dharm has the largest religious monument in the world in the form of Angkor wat. It is situated in combodia and spread across over 400 acres / 1.6 km².


It was listed as a UNESCO World Heritage Site in 1992, which encouraged an international effort to save the complex.
It was originally built as a Hindu temple dedicated to the god Vishnu. In Khmer, the Cambodian language, Angkor means "city" and Wat means "temple grounds".


So Angkor Wat means "Temple City". Its original name was Vrah Vishnuloka or Parama Vishnuloka, meaning the sacred dwelling of Vishnu in Sanskrit.
But, it gradually turned into a Buddhist temple towards the end of the 12th century & is still used for worship today.


Angkor Wat was initially designed and constructed in the first half of the 12th century, during the reign of Suryavarman II, as the king’s state temple and capital city. It was built without the aid of any machinery, as there was no machinery available at that time.


Evidence for these dates comes in part from inscriptions, which are vague, but also from the architectural design and artistic style of the temple and its associated sculptures.

Another aspect is that the five central towers of Angkor Wat symbolize the peaks of Mount Meru,
