Thread: Here's the most fun & frivolous tech news today: Railway Operation Depot in the Chinese city Dalian just published an article on their harrowing journey racing to restore the old version of Flash after Adobe's ban, which collapsed their system and paralyzed the railway /1

The article was written a bureaucratic, propaganda, war diary style, with a detailed timeline down to minutes. "Jan 12, 8:16, Depot received malfunction report. The computer system stopped displaying pages...within 30 mins, computers in the entire depot had the same prob" /2
"After calls and online searches, we identified the source of the issue is American company Adobe's comprehensive ban of Flash content" /3
"8:41, IT department held an emergency meeting & took on four urgent measures: 1. informed supervisors and higher-ups 2. immediately started searching for alternatives to solve page inaccessible issue 3. founded a software task force 4. founded a hardware task force" /4
..."12:10 we temporarily maintained the stability of the depot"
..."13:00 a second crisis meeting was held to address three deeply rooted issues"
..."14:11 another crisis erupted. We are no longer able to print pages, again" /5
...
"20:20 A third wave of bugs was upon us. Flash we restored from Ghost system was disabled from all computers again...We held the third emergency meeting. The only goal: fix the Flash from (pirated) Ghost windows system" /6
..."Jan 13, 01:09 Wan Jia Ling stop is fixed!...we all gathered and confirmed. The room burst with cheers." /7
The article is so long and surprisingly entertaining, and it ends with "20+ hours of fight. No one complained. No one gave up. In solving the Flash problem, we turned the glimpse of hope into the fuel for advancement." link: https://t.co/2evuiGmkkT /8
Honestly, this is the Y2K content the world owes us for 20 years. /END
the article reads like dozens of parents coming together to overcome the insurmountable challenge of updating Flash. They then wrote a war diary on those 20 brutal hours. Not sure if my sense of humor is wicked, but this made my day.

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!
