1/ Happy to announce that we have submitted our #paper ‘Bayes Lines Tool (BLT) - A SQL-script for analyzing diagnostic test results with an application to SARS-CoV-2-testing’.
In this ⬇️thread⬇️, I will explain why our tool is that powerful for decision makers. #UnbiasedScience

Substantial analysis of @BenMarten regarding the mortality in Germany. Particularly noticeable is the "excess mortality" in December. Ben states that "lockdown deaths" could play an important role here. I would like to elaborate my thoughts on that. ⬇️Mini-Thread⬇️
Factor 1: Vitamin D deficiency.
Many people (especially elderly) have been locked in during the summer. Also the majority of holiday trips have been cancelled, leading to a lower 25(OH)D blood serum level as usual. The body can store vitamin D up to several months.
As vitamin D is a hormon that modulates the immune responses, we can assume that the lockdown measures had some adverse effect on our immune system. Especially elderly people in retirement homes must have been severely affected.
Factor 2: Loneliness
"Loneliness, it seems, can lead to long-term "fight-or-flight" stress signaling, which negatively affects immune system functioning. Simply put, people who feel lonely have less immunity and more inflammation than people who
Factor 3: Hyper Hygiene
Constant disinfections and high hygienic standards weaken the immune system. It gets literally "out of

1/: The Nuremberg Code is a set of research ethics principles for human experimentation created as a result of the Nuremberg trials at the end of the Second World War. In light of the current events, they are more actual than ever before. ⬇️an important thread⬇️
2/: These so-called ‘Doctors’ Trial’ focused on physicians who conducted #inhumane and #unethical human experiments in German concentration camps, in addition to those who were involved in over 3,500,000 sterilizations of German citizens. (the picture shows doctors/criminals)
3/: Ten points of the code were given in the section of the verdict entitled "Permissible Medical Experiments". They can be found in detail on the following website:
4/: Point #1 means that the person involved should have legal capacity to give consent; should be so situated as to be able to exercise free power of choice, without the intervention of any element of force, fraud, or deceit.
5/: Using an insufficiently-tested vaccine on humans is unethical. However, as long as people voluntarily consent to receive the vaccine, being informed about all risks, everything is OK. Doing this with force, however, is against the Nuremberg Code.

1/: Avicenna was a Persian scientist, who lived 1000 years ago. He put two lambs in separate cages, which had the same health conditions. But only one lamb could see a wolf that was put in a third cage. The observations were astounding. (h/t @farmer_student) ⬇️a thread⬇️
2/: Both lambs were provided with the same feed. Also, the weight was exactly the same when the experiment started. Several months later, the lamb with sight on the wolf became cranky, restless, weak, and showed a significant weight loss and signs of poor development.
3/: The lamb that was under chronic stress as it was placed in a situation of constant apparent danger died eventually. 🐑🪦 In fact, the wolf did not pose a danger at all, but this was beyond the lamb's perception.
4/: This experiment showed that increased levels of the stress hormone cortisol have a bad impact on the metabolism of mammals. And 1000 years after this experiment, we are facing a similar situation again but with the difference that we are aware of the impact of stress.
5/: Currently, we are overwhelmed with medial and governmental propaganda with respect to a common cold virus (that might hypothetically be more lethal though) that doesn't do harm to the majority of the people. Extreme global measures are taken.

1/: The inventor of the corona PCR-Test @c_drosten is one of the #protagonists of the current crisis. He is known for involving himself in contradictions. In 2014, he gave a legendary #interview to @wiwo (https://t.co/jzTRh5Suhc) that I will address in this ⬇️short thread⬇️.
2/: The interview is significant because @c_drosten made totally sane statements back then that follow the principle of common sense. Considering his involvement in the "genesis of the current pandemic", his assertions appear in an entirely different
3/: In 2014, for instance, washing the hands was sufficient against being infected by coronaviruses. Several years he demands measures that destroy national economies and social life worldwide.
4/: Young @c_drosten also severely criticized the fact that Saudi Arabia used the PCR method to detect potential infections. From his point of view, that specific method could lead to many irrelevant cases. Nowadays, his view shifted his opinion towards 'collective punishment'.
5/: Whereas he demands "testing, testing, testing" nowadays and spreads panic and fear via (social) media, he heavily condemned that behaviour of Saudi media in 2014. On top of that, he expressed his concern that medial panic could increase the number of lab tests significantly.

The #Corona crisis began with a panopticon of absurd events, improbable coincidences and outright lies.
Time for a review of the impossibilities.

Some random interesting tidbits:
1) Zuck approves shutting down platform API access for Twitter's when Vine is released #competition
2) Facebook engineered ways to access user's call history w/o alerting users:
Team considered access to call history considered 'high PR risk' but 'growth team will charge ahead'. @Facebook created upgrade path to access data w/o subjecting users to Android permissions dialogue.
3) The above also confirms @kashhill and other's suspicion that call history was used to improve PYMK (People You May Know) suggestions and newsfeed rankings.
4) Docs also shed more light into @dseetharaman's story on @Facebook monitoring users' @Onavo VPN activity to determine what competitors to mimic or acquire in 2013.

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!
