Impressive! There has been significant progress in GANs over the past few years, but that's not really what we're seeing here... [1/8]

(Thread. Buckle up! 👇🔥)
If you were to include images in a Tweet that promoted progress specifically in GAN research (relativistic discriminators, wasserstein constraint, unrolled steps, spectral norm, etc.), it'd look like this... Not quite so catchy! 🤓 [2/8]
It's like a different field of research.

The progress in the latest NVIDIA paper was made 100% with domain-specific changes independent of GANs. The authors say so themselves in the introduction: [3/8]

#MachineLearning in System #trading. Here is a simple idea to improve your system.

#MachineLearning(#ML,#DeepLearning) is used in stock trading algorithms/system intraday or EOD based system. Mostly these systems are predictive systems.

(1/n)
These predictive system are based on given OHLC and other indicators (like RSI,MA,etc) tries to predict the value of next close/open/...using Machine learning/AI algorithms. There are many simple statistic based systems(call it non-AI system) also... (2/n)
Aim: to improve win ratio using #MachineLearning specifically classification algorithms
Input: your historical system trade data with various system parameters(like, rsi, supertrend , atr, etc) along with status or trade(winning or losing)

Claas Relotius (na foto), 33, é um premiado repórter alemão. Foi demitido da @DerSPIEGEL em 19/12. Descobriram que inventava até os diálogos de suas matérias para a Spiegel, e também Süddeutschegazin, Financial Times Deutschland, Die Welt e Frankfurter Allgemeine Sonntagszeitung
Lembra muito o caso Jayson Blair, do @nytimes. Só que dessa vez o caboclo é branco e europeu. Premiadíssimo. De freela passou a editor na Spiegel. Anotem: não é o único. Trabalhei em algumas das mais importantes redações do Brasil, como editor e repórter: vi vários assim.
Qual é a solução, quando até mesmo o jornalismo profissional das mais importantes redações do mundo inventa histórias, como o mais canalha dos blogueiros ou Youtuber? Leitores mais preparados. Com um olhar mais crítico. Já não basta a mediação e curadoria. É preciso saber mais.

✨🧠 The ecosystem that has grown up around @TensorFlow in the last few years blows my mind. There's just so much functionality, compared to some of the other, newer frameworks.

👉Consider this an ever-expanding thread for me to take notes + wrap my brain around products. Ready?
1) @TensorFlow Extended (TFX)

It's no secret that I 💕 #TFX and all of its tooling for deploying machine learning models into production. If you care about keeping your models up-to-date and monitoring them, you should check out the product + its paper.

tensorflow.org/tfx/?hl=zh-cn
2) @TensorFlow Hub

If you want to train your model on a small data set, or improve generalization, you'll need to use something called transfer learning. #TFHub modules make it easy—and are available in an #OSS marketplace: tfhub.dev.

Now up: Zachary Brown, Lead Data Scientist at S&P Global on #DataScience and #OpenEducation for the enterprise. Dayjob: #AI, Sidehustle: building #digital skills using #opensource #ODSCWest @School_GC
#DigitalLiteracy - Why? Effective work today requires a lot of associated learning. @linuxfoundation @github #VersionControl #Visualization -- continuous learning is critical. Optimal tools & processes are probably not the ones you are using now (Matlab vs. Scikit-Learn)
Need an evolving understanding for what tools are available today to get your work done. If you want your business people to work with your #datascience team, they need to understand what data is and what it can do. Also helps to avoid chasing buzzwords and bling.

Closing the loop on #Diagnostics #Tweetorial with example #AppleWatch #AFib #Screening. From a company website: "Atrial fibrillation is a silent killer. The heart arrhythmia causes more life-threatening strokes than any other chronic condition, and will affect 1 in 4 of us."
"But the sad fact is that atrial fibrillation often goes unnoticed: It is estimated that 40% of those who experience the heart condition are completely unaware of it."
Using #AppleWatch technology and #DeepLearning #AI #ML, a device algorithm can reportedly detect atrial fibrillation with high accuracy (c-statistic 93%).

#Bitcoin is bigger than all the companies that try to capitalise on its #blockchain #technology.

#Bitcoin + #IoT + #DeepLearning will transform the global political & financial system without permission.

#blockchain #LightningNetwork #fintech #blockchain #disruptiveinnovation
#Decentralisation will take time.

#Bitcoin is decentralised although still attached to a centralised world.

⚠️ This is the alpha.
⚠️ #LightningNetwork is the beta.
If you want to change society you need to change the social paradigm, or offer an incentive greater than money to discourage greed. #bitcoin #LightningNetwork ⚡️

#Tweetorial on #Diagnostics and #Screening interpretation.
An otherwise healthy 40 year old woman comes to you after reading on the internet about a terrible disease that one in a thousand women get, and a highly accurate test that can save her life.
The test is over 99% accurate in people with the disease. For those without disease, the test is only wrong 5% of the time.

You order this test and it comes back positive. The woman anxiously asks you, do I have the disease? What is the chance this woman has the disease?
Assuming they weren't immediately fooled by the "test is only wrong 5 % of the time," most I've asked correctly recognize the stats provided are Sensitivity = 99% and Specificity = 95%, and that the objective is to determine the Positive Predictive Value.

@DeepIndaba top tips from an extremely useful panel discussion on how to write a great research paper:
- tell one story throughout the paper. make sure this story is clear and that you are able to frame your paper in 1 sentence.
- be clear about what the problem is and about the solution you are putting forward.
- you don't have to put everything you did in everything you write.
- be academically honest. don't oversell your results.
- introduce a concept and its mathematical notation at the same time to keep your reader in the loop.
- spend time on creating images that help to visualize concepts, put them at the top of the page with a self-contained caption.

1/ What are #deepfakes + #AI generated synthetic media; what threats do they pose to #humanrights, #journalism and #publicsphere? What should we fear? What can we do? Thread w/ key tech + usages from recent expert mtg summarizing blog.witness.org/2018/07/deepfa…
2/We've had fake images and CGI for years, so what's different now (beyond enabling us to transplant Nicolas Cage's face to other people). The ease of making #deepfakes is captured by the vlogger Tom Scott
3/ = Barriers to entry to manipulate audio and video are falling - costs less, needs less tech expertise, uses open-source code + cloud computing power. Plus, sophistication of manipulation of social media spaces by bad actors makes it easier to weaponize and to micro-target.

Reinforcement learning does not scale. Efficient environmental sampling does. One aspect of intelligence is the ability to predict the world while observing so little. #deeplearning #ai
To observe so little implies that there's an imaginary simulation that is able to extract new information without interacting with the environment. In short, a game is played between imagination and reality.
Deep Learning has revealed to us what methods work very well in reality. This leads to imagined new architectures that will be exponentially more capable than the previous architectures. #deeplearning #ai #agi

Afternoon twitterverse! Let’s talk about AI in Radiology, which is the main focus in my research.
Any talk of AI begs for a definition of AI, and there are as many definitions as there startups that are “AI-enabled”.
For our purposes we'll just call anything that performs one of the higher level behaviours associated with animals e.g. learning, planning, problem-solving, creating etc.

Inspired by the big ol' long list of deep learning models I saw this morning, and @SpaceWhaleRider's love of science-y A-Z lists, I've decided to create an A to Z series of tweets on popular #MachineLearning and #DeepLearning methods / algorithms.

Ready? Here we go:
A is for... the Apriori Algorithm!

Intended to mine frequent itemsets for Boolean association rules (like market basket analysis). Ex: if someone purchases the same products as you, in general, then you'd probably purchase something they've purchased.

cran.r-project.org/web/packages/a…
B is for... Bootstrapped Aggregation (Bagging)!

This is an ensemble meta-algorithm designed to improve the stability and accuracy of machine learning algorithms used in statistical classification+regression. Reduces variance, helps to avoid overfitting.

Example: Random Forests.
