Best Practices for Improving Artificial
Google’s latest neural network, BigSleep, uses two different types of neural networks to make
decisions. One is a generative adversarial network (GAN) that takes random noise and outputs
images. The other is a discriminator network. These systems can learn from their own
mistakes and improve as they go, but they are still far from perfect. So, what are the best
practices to improve AI? You can start by reading the following articles.
Generate 1,000 types of things
The Big Sleep is an AI that should be able to generate 1,000 different types of things. It is
available as a Google Colab notebook. You’ll need to familiarize yourself with Colab before
trying it out. Until then, it’s free to try. Other ways to test BigSleep will probably open up in the
weeks to come. You can check out some images that BigSleep generated in r/MediaSynthesis.
This artificial intelligence can match images, descriptions, and text. BigSleep works by looking
through the outputs of BigGAN to find images that maximize CLIP’s scoring. It then tweaks the
input noise in the BigGAN’s generator until it finds an image that matches the prompt. The
entire process can take as little as three minutes. However, the program is not yet ready for
use on human beings.
Combines two neural networks
The BigSleep is an AI system that combines the predictive abilities of CLIP and BigGAN.
BigGAN specializes in 1000 image categories, including animal species. The BigSleep system
uses this knowledge to search through the output of BigGAN for an image that best matches a
given prompt. As a result, it can generate more than 1,000 types of images, with each image
corresponding to a particular animal type.
The researchers used 35 convolutional layers to create the model, which consists of an
encoder and decoder. In one task, the encoder takes a full-length sleep record and gradually
encrypts it into latent space. The dataset was divided into 8 million input spaces, with each
recording centered in one of these spaces. When the algorithm learned from the data, it
performed remarkably well on both tasks.
OpenAI released the code for a text-to-image AI system in 2021. This AI system uses a
multimodal neural network called CLIP, which evaluates text for images. The result is a pretty
decent approximation of what you can say in words. This is an extremely promising AI system
that can be used in many applications. The BigSleep is also a Colab playground, where you
can try out the new technique and see if it works for you.
The Big Sleep is like a sequel to DeepDream, but arguably better. DeepDream generated
timeless alien views, whereas The Big Sleep lets you probe CLIP’s knowledge with natural
language. Basically, anything you say to CLIP will be rendered through the lens of an alien
dream. But the real challenge lies in integrating “omics” data into the data. It’s unclear what
will happen when the Big Sleep and DeepDream are combined.
Uses CLIP to match images and descriptions
The Big Sleep is a sequel to DeepDream, which generated alien views that seem timeless. In
this game, you can probe CLIP’s knowledge by talking to it in natural language. Basically,
whatever you say will be rendered through an alien dream-like lens. You can even ask CLIP to
guess the type of food based on its appearance. The end result is a game that can tell the
difference between pizza and calzone.
The CLIP model has been trained to match images and descriptions. The OpenAI team
released the weights for their model in January 2021. It learned to match images and
descriptions by looking at hundreds of millions of images. The CLIP model learns how images
and descriptions are described in abstract ways, such as through multimodal neuron work. The
algorithm then uses these representations to determine which caption matches a particular
The Big Sleep has two neural networks: one, called BigGAN, takes in random noise and
outputs images. The other uses a discriminator network and an image-generating network.
Together, these two networks can approximate anything you can describe with words. The
BigSleep’s model is a hybrid of the two. It is currently in the Alpha phase and can be used for
The CLIP model uses machine learning to learn about images and describe objects. It has
been trained with 400 million image-text pairs and is highly accurate. A special power called
‘zero shot classification’ makes CLIP capable of recognizing images that were not included in
its training process. It also encodes the captions into a transformer model, which then extracts
the semantic meaning of the images.
Learns from its mistakes
AI is a powerful tool that can be used to train machine learning algorithms. This is done by
introducing the notion of “virtual goals,” which count each failed attempt as one more step
towards the actual goal. It is similar to how humans learn to ride a bike, where they fail a
couple of times before achieving balance. Those failed attempts, however, are valuable
because they taught humans how to ride correctly. In essence, failure is a form of success,
since each failure helps the human get closer to his or her goal.
The Big Sleep is like a sequel to DeepDream, only better. While DeepDream generated
timeless views, The Big Sleep lets users probe CLIP’s knowledge with natural language. What
you say to CLIP will be rendered through an alien dream-like lens. The Big Sleep is also a
great source of entertainment for children. The Big Sleep is an aesthetically pleasing game.
It’s an excellent way to engage with artificial intelligence, and it’s a wonderful companion for
those who enjoy fiction.
Is promising in contemporary medicine
While it is unclear how AI can improve current clinical practices, it has huge potential in the
area of sleep disorders. As many as 50 million US adults suffer from sleep disorders, which
can have major consequences on work productivity and quality of life. AI can help doctors
diagnose these sleep disorders more rapidly, which would dramatically improve patient care.
But before AI can improve the diagnosis of sleep disorders, it must be proven it is safe for use
While PSG data is largely unreliable, it is still used to diagnose sleep-related movement
disorders outside of clinical settings. Deep learning algorithms can be used to assess data
from noncontact sleep assessment devices. In addition, consumer wearables can use
photoplethysmography, accelerometry, or headband-embedded dry electrode EEG sensors.
Artificial intelligence-based sleep assessment is likely to have many other applications in
modern medicine, such as improving the diagnosis of sleep disorders.
A recent study found that ML techniques can automate PSG analysis, which is a cornerstone
of sleep diagnostic testing. Sleep techs score PSGs in a structured manner, and the analysis
is often focused on the apnea-hypopnea index (AHI), which helps diagnose sleep-disordered
breathing. This approach may contribute to better understanding of the genetic basis of the
disorder, and it also likely helps explain the modest effects of CPAP on the symptoms of sleep-
AI will also improve healthcare by automating procedures and reducing technician burden. By
acquiring PSG data automatically, AI can cut down on the time it takes to interpret the results.
It will also help doctors understand sleep disorders and how they impact the health of patients.
It will be exciting to see AI transform medical practices. But it will take some time. And it will
require an entirely new paradigm in health care. For now, it is too early to say whether AI will
replace the human brain.
