"How a largely untested AI algorithm crept into hundreds of hospitals". "The use of algorithms to support clinical decision-making isn't new. But historically, these tools have been put into use only after a rigorous peer review of the raw data and statistical analyses used to develop them. Epic's Deterioration Index, on the other hand, remains proprietary despite its widespread deployment. Although physicians are provided with a list of the variables used to calculate the index and a rough estimate of each variable's impact on the score, we aren't allowed under the hood to evaluate the raw data and calculations.

"Furthermore, the Deterioration Index was not independently validated or peer-reviewed before the tool was rapidly deployed to America's largest healthcare systems."

"AI-powered drone deployed in Libya has possibly killed people without any human interference." "The drone, Kargu-2, is made by a Turkish company (STM) and fitted with a payload that explodes once it makes an impact or is in close proximity with its AI-identified target. It is not clear whether the attacks resulted in any deaths."

"The revelations were made in a report published in March 2021 by the United Nations (UN) Panel of Experts on Libya which stated that the drone was a 'lethal autonomous weapon' which had 'hunted down and remotely engaged' soldiers which are believed to have been loyal to Libya's General Khalifa Haftar."

"Scientists create online games to show risks of AI emotion recognition." "A team of researchers have created a website -- emojify.info -- where the public can try out emotion recognition systems through their own computer cameras. One game focuses on pulling faces to trick the technology, while another explores how such systems can struggle to read facial expressions in context."

"Alexa Hagerty, project lead and researcher at the University of Cambridge Leverhulme Centre for the Future of Intelligence and the Centre for the Study of Existential Risk, said many people were not aware how common emotion recognition systems were, noting they were employed in situations ranging from job hiring, to customer insight work, airport security, and even education to see if students are engaged or doing their homework."

The first "drone war". This video is from last November but I didn't see it until today. According to this analyst (Shekhar Gupta), the reason for Azerbaijan's decisive victory in the Azerbaijan-Armenia war of 2020 was Azerbaijan's effective use of drones (manufactured by Turkey and Israel) and Armenia's inability to defend against them.

He introduces these with a preamble about how you can change generated images if you can change the "latent space" inputs that the generative neural network uses, but the dimensions don't have any "interpretable" meaning -- or rather, they didn't used to, but now they do, and that's what makes all these new capabilities possible.

AI soll unsere Kommunikation bewerten

Eine "künstliche Intelligenz" soll nach dem Willen der EU künftig entscheiden, ob wir uns in unserer Kommunikation richtig verhalten. Facebook Messenger, Gmail & Co sollen jede Kommunikation auf verdächtiges Text- und Bildmaterial scannen. Und zwar vollautomatisiert, durch den Einsatz von sog. ‘Künstlicher Intelligenz’ – ohne, dass ein Verdacht vorliegen muss.

Die Unschuldsvermutung, ein Grundpfeiler in einer demokratischen Gesellschaft, spielt keine Rolle mehr.

Nachem sich niemand gewehrt hat, als entschieden wurde, dass alle Menschen, die aus Nicht-EU-Staaten zu uns kommen, alle 10 Fingerabdrücke abzugeben haben - wie es bei Verbrechern üblich ist, sollen demnächst alle, die einen Personalausweis beantragen, schon mal 2 Fingerabdrücke abgeben. Auch damit werden wir nur noch eine Salami-Scheibe besser behandelt als die zu uns Geflüchteten.

Nun wird auch noch die Kontrolle über die Einhaltung von "Recht und Ordnung" an private Internetprovider abgegeben. Die privaten Datensammler dürfen - nein, sie sollen sogar, Profile über uns anlegen und unsere E-Mails und unsere Chatverläufe rastern.

Data Mining, das Interpretieren von Zusammenhängen zwischen Daten, die evtl. nichts miteinander zu tun haben, soll über uns entscheiden. Menschen kommen in diesen Abläufen nicht mehr vor. Meldet ein Algorithmus einen Verdachtsfall, werden alle Nachrichteninhalte und Kontaktdaten automatisch und ohne menschliche Prüfung an eine private Verteilstelle und weiter an Polizeibehörden weltweit geleitet. Die Betroffenen sollen nie davon erfahren.

US-Dienste wie GMail und Outlook.com führen solche automatische Nachrichten- und Chatkontrolle bereits durch. Nur Ende-zu-Ende verschlüsselte Mails sind von solchen Kontrollen noch ausgenommen.

Patrick Breyer, EU Abgeordneter der Piratenpartei, warnt:
  • Alle deine Chats und E-Mails werden automatisch auf verdächtige Inhalte durchsucht. Nichts ist mehr vertraulich oder geheim. Kein Gericht muss diese Durchsuchung anordnen. Sie passiert immer und automatisch.
  • Falls die Maschinenprüfung anschlägt, werden deine privaten Fotos und Videos von Mitarbeitern von internationalen Konzernen und Polizeibehörden angesehen. Auch intime Nacktbilder von dir werden dann von unbekannten Menschen auf der ganzen Welt gesichtet, in deren Hände sie nicht sicher sind.
  • Flirts und Sexting werden mitgelesen, denn Texterkennungsfilter schlagen besonders häufig auf solche intimen Chats an.
  • Du kannst unschuldig in den Verdacht geraten, Material von Kindesmissbrauch zu verschicken. Denn die Bilderkennungsfilter sind bekannt dafür, dass sie auch auf völlig legale Urlaubsfotos mit Kindern am Strand anschlagen. 90% aller maschinell gemeldeten Verdachtsfälle erweisen sich als unbegründet, so die Schweizer Bundespolizei. 40% aller in Deutschland eingeleiteten Ermittlungsverfahren richten sich gegen Minderjährige.
  • Bei deiner nächsten Auslandsreise könnten dich große Probleme erwarten. Verdachtsmeldungen werden unkontrollierbar an Staaten wie die USA, wo es keinerlei Datenschutz gibt, weitergeleitet – mit unabsehbaren Konsequenzen.
  • Geheimdienste und Hacker können einfacher Zugriff auf deine privaten Chats und E-Mails erhalten. Denn sobald sichere Verschlüsselung für den Einsatz der Chatkontrolle ausgehebelt wird, ist die Tür offen zum massenhaften Auslesen deiner Nachrichten durch jeden, der die technischen Mittel dazu hat.
  • Das ist nur der Anfang. Ist die Technologie zur Nachrichten- und Chatkontrolle einmal etabliert, kann sie spielend leicht auch für andere Zwecke eingesetzt werden. Und wer garantiert, dass die Verdächtigungsmaschinen künftig nicht auch unsere Smartphones und Laptops kontrollieren?
Stopp den Big Brother! Maschinen dürfen nicht über unser Schicksal entscheiden!

Even though I'm not good at math, I find it very exciting to rediscover the same patterns and methods in art.
(Music, sound design, Soundeffects, Graphics, Postproduction, Visual Art & FX, Motiontracking or Compression)

Maybe I´m wrong but I think, things get really flashy in #nature (see this amazing video of #mushrooms) when cell chemistry follows the same rules.


Everything is waveform, is dynamic and when you see the beauty of the dynamic, you may notice the pattern match that I see in it.


Maybe you think I'm wrong and the three videos are not connected in any way.

Maybe the connection is not so easy to see and I can not explain it well enough.
But I think quantum physics unites these patterns and shows up in different orders of magnitude.

Seeing through clouds. "Over the last few years, several cloud removal techniques have been developed: Sentinel-2 Cloudless, Mapbox Cloudless Atlas and Google's Cloudless Satellite Map. These techniques are sifting through multiple years of images to create cloud-free scenes. This works fine if the goal is to improve the aesthetics of the satellite images, but the trade-off is recency. In applications like ours, where we rely on the most recent images to monitor changes on the land, these techniques cannot be used."

"Clouds can be broadly classified into two types: dense, and thin or cirrus clouds. Dense clouds do not allow the penetration of visible spectral radiation from the ground and tend to cast a shadow on the ground."

"Thin or cirrus clouds on the other hand are transparent or semi-transparent clouds. Most spectral bands can partially see through these clouds. This is key to accurate de-clouding with our model."

"Our main contribution is to create a training dataset based on (cloud, no-cloud) pairs for the same geography but from different days. The machine learning model then learns to re-construct the no-cloud sample from the cloud sample."

"The basic assumption is that between cloud and no-cloud scenes only cloud pixels will change. This simple approach worked very well for us."

Experiments with an artificial model that mimics real neurons. "The neural simulation now includes these behaviors: A precise neuron action threshold, a precise action pulse waveform in axons, a variable action recovery (refractory) period, inhibitory neurons and synapses, rapid rise / slow drop of potential in synapses, temporal summation of pulses in synapses, spatial summation of pulses in dendrites, and long-term potentiation (LTP) and depression (LTD) in synapses."

His simulation uses neurons connected in an extremely regular, symmetric fashion, and he used a 1-pixel-per-neuron representation scheme to watch the simulations, with color codes for the various neuron states.

What has he learned?

Neurons have a precise action threshold. "This behavior is well understood and indicates that the brain is not a purely analog system. This aspect is more like a digital behavior. A neuron can only fire or not fire. There is no partial credit for an input potential just below the action threshold. It is ironic that many public ANNs (simulations on digital computers) attempt to be fully analog." That's because backpropagation, an algorithm based on the chain rule in calculus, needs for everything to be fully differentiable.

"The action pulse that travels through the axon also looks like a digitally generated square wave. It switches on very precisely, has a precise duration (approx. 1 msec), and then switches off very precisely -- with one exception: when the action potential switches off, it goes negative for short period. It is interesting that this is also a digital behavior."

"Once a neuron fires, it normally cannot fire again for approx. 10 msec."

"Neuroscientists have observed some neurons send excitatory (positive) pulses to other neurons and cause more activations, and some send inhibitory (negative) pulses and suppress activations."

"The complex electro-chemical processes in the synapses change the axon pulse dramatically. It is typically reduced in strength (by 95%!), slightly delayed, and no longer looks like a digital square wave."

"Time-based behavior occurs when multiple action pulses pass through a single synapse in rapid succession, close enough to overlap."

"This time-based behavior was discovered in 1966 and is still considered to be one of the main mechanisms supporting long-term memory and learning in the brain."

Does someone know Notco?

Dies steht in den FAQ:
"Artificial Intelligence is about learning everything from life in order to improve it and it is our main tool to reinvent the food we love to eat. Thanks to AI, we created Giuseppe. A proprietary algorithm who learns and studies infinite combinations of plants day by day and that can replicate animal products - or make them even better. By processing and learning the infinity of plants and vegetable combinations we manage to store and obtain an enormous amount of information - chemical, molecular, physical and nutritional - with a higher level of detail which would be unimaginable with the sole use of the human mind. Thus, with Giuseppe on our side, we are going to reinvent the food industry. Why Not?"

In Deutschland nicht erhältlich.

Für genauere Infos zu Notco und der AI Giuseppe wäre ich dankbar.

another thing i recently learned about is Hopfield nets. they are fairly different from typical modern neural nets, but pretty cool in their own right. it's basically an undirected graph that encodes memories in a way that can complete its activation state towards learned patterns (attractors): if it learned "sofia" and "zelda", and you set the activation to "zofia" it will change it to "sofia".

apparently there is evidence that similar things happen in our brains 😎.

"Early in life, humans first learn to walk, and then a few years later, they learn to ride bicycles, and finally, as young adults, they learn to drive cars. In learning how to do each new task, humans don't forget previous ones. Artificial neural networks, on the other hand, struggle to learn continually and consequently suffer from catastrophic forgetting: the tendency to lose almost all information about a previously learned task when attempting to learn a new one."

"Neuroscientists have long been aware about the existence of pyramidal neurons in the cortex, and these neurons are quite different from the artificial neurons used by contemporary neural networks. Each pyramidal neuron has hundreds of dendrites, which receive signals along incoming synapses from other neurons. The role of each dendrite is to detect a different input pattern to the neuron, and if a certain pattern is detected, the neuron will be depolarized, i.e., more likely to become active. Only a fraction of the input signals received by a neuron along incoming synapses are able to make that neuron active, and dendrites essentially determine which signals affect the neuron."

"Moreover, the patterns detected by dendrites are highly sparse (as neural activations are sparse in general) and less likely to interfere with each other. According to the Thousand Brains Theory of Intelligence, this likely explains why humans are able to learn continually without catastrophic forgetting. When a person has a novel experience, dendrites ensure that only a subset of incoming synapses are modified for learning purposes (precisely those that yielded the sparse activity pattern). Other synaptic connections established as a result of previous experiences remain largely untouched, and thus are not overwritten. This is unlike in neural networks, where all parameters are updated via backpropagation of errors."

Article goes on to describe some approaches to modeling dendrites and sparsity in artificial neural networks: Elastic Weight Consolidation, Intelligent Synapses, Supermasks, and Gated Linear Networks.

"Early in life, humans first learn to walk, and then a few years later, they learn to ride bicycles, and finally, as young adults, they learn to drive cars. In learning how to do each new task, humans don't forget previous ones. Artificial neural networks, on the other hand, struggle to learn continually and consequently suffer from catastrophic forgetting: the tendency to lose almost all information about a previously learned task when attempting to learn a new one."

„Feed an AI a photo of a man cropped right below his neck, and 43% of the time, it will autocomplete him wearing a suit. Feed the same one a cropped photo of a woman and 53% of the time, it will autocomplete her wearing a low-cut top or bikini.“
