2. A refreshing contrast to the so-called "expert reactions" found here, including from one of the authors of the review (Prof David Robertson)!
"expert reaction to a preprint reviewing the evidence on the origins of SARS-CoV-2"

3. Peter Gutierrez points out in his response that 4 of the authors of “The Origins of SARS-CoV-2: A Critical Review”, also wrote “Proximal Origin of SARS-COV-2”.
His critique focuses on:
1. RaTG13
2. Enhanced adaptation to the human host

4. As to be expected, Sydney University and its iconic virologist, Eddie Holmes, who is "not available for interview", are crowing over this biased review

This review contains elementary errors as exposed here:
1. https://t.co/YJ50huifly
one of the authors (Stuart Neil) then claimed
"Didn’t N501Y come up in ACE2 TG mice too?

Here is how B.1.1.529 (#Omicron #B11529) compares to Alpha, Beta, Gamma, Delta variants.

Omicron has highest novel Spike mutations including striking cluster on the "crown" suggesting significant selection pressure & antigenic distinction from prior strains

Why 'Omicron', Not 'Nu' or 'Xi'?

3. The Omicron variant has been found in nearly every province of South Africa, as well as Botswana, Belgium, Israel, UK and Hong Kong.
This month, Israel held an exercise, The “Omega Exercise”, meant to prepare for a hypothetical, new COVID-19

At the heart of this lies the most important technique in modern deep learning - transfer learning.
Let's analyze how it
THREAD: Can you start learning cutting-edge deep learning without specialized hardware? \U0001f916
— Radek Osmulski (@radekosmulski) February 11, 2021
In this thread, we will train an advanced Computer Vision model on a challenging dataset. \U0001f415\U0001f408 Training completes in 25 minutes on my 3yrs old Ryzen 5 CPU.
Let me show you how...
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!
