I've seen many news articles cite that "the UK variant could be the dominant strain by March". This is emphasized by @CDCDirector.

While this will likely to be the case, this should not be an automatic cause for concern. Cases could still remain contained.

Here's how: 🧵

One of @CDCgov's own models has tracked the true decline in cases quite accurately thus far.

Their projection shows that the B.1.1.7 variant will become the dominant variant in March. But interestingly... there's no fourth wave. Cases simply level out:

Just because a variant becomes the dominant strain does not automatically mean we will see a repeat of Fall 2020.

Let's look at UK and South Africa, where cases have been falling for the past month, in unison with the US (albeit with tougher restrictions):


Furthermore, the claim that the "variant is doubling every 10 days" is false. It's the *proportion of the variant* that is doubling every 10 days.

If overall prevalence drops during the studied time period, the true doubling time of the variant is actually much longer 10 days.

Simple example:

Day 0: 10 variant / 100 cases -> 10% variant
Day 10: 15 variant / 75 cases -> 20% variant
Day 20: 20 variant / 50 cases -> 40% variant

1) Proportion of variant doubles every 10 days
2) Doubling time of variant is actually 20 days
3) Total cases still drop by 50%

So today, I am going to quickly talk about 4 or 5 countries where you can get residence visas.

Why residence visas?

For starters, they are cheaper, FAR CHEAPER than passports, and offer almost all the benefits, not not, but a large swathe of them.

Second, residencies can be...

a pathway to citizenship.

In one or two of the countries I will talk about tonight, if you renew your residencies long enough, and fulfill all requirements, according to their law, which differs from country to country, you become eligible to apply for full citizenship.

So...

you can see why they are good enough?

Cool. Alright, let's begin.

The first country is

1. Barbados

Yes, @Rihanna's country.

The first thing I love about it is it's fully black, majority descendants of ex-slaves of Igbo extraction.

That's why they refer to their country...

Barbados last year officially launched its 12-month Barbados Welcome Stamp, a new visa that allows remote workers to live and work from the Caribbean country for up to a year.

Applicants must electronically submit documents, such as a copy of their international passport and...
THREAD: How is it possible to train a well-performing, advanced Computer Vision model 𝗼𝗻 𝘁𝗵𝗲 𝗖𝗣𝗨? 🤔

At the heart of this lies the most important technique in modern deep learning - transfer learning.

Let's analyze how it


2/ For starters, let's look at what a neural network (NN for short) does.

An NN is like a stack of pancakes, with computation flowing up when we make predictions.

How does it all work?


3/ We show an image to our model.

An image is a collection of pixels. Each pixel is just a bunch of numbers describing its color.

Here is what it might look like for a black and white image


4/ The picture goes into the layer at the bottom.

Each layer performs computation on the image, transforming it and passing it upwards.


5/ By the time the image reaches the uppermost layer, it has been transformed to the point that it now consists of two numbers only.

The outputs of a layer are called activations, and the outputs of the last layer have a special meaning... they are the predictions!
