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:

"finally, the time has slip and slid its slimy course through to us - and we're the vicious bastards of the new generation. we do not relent, and we should not be held to account for our ancestral faults"

"It's amazing that the Xi variant seems to have somehow managed to evade detection..."

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

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!
