How Does Google DeepDream Work?

If you are interested in artificial intelligence (AI), you have probably heard of Google DeepDream. It is a computer vision program that uses neural networks to generate images based on certain visual characteristics. 

Although DeepDream’s algorithmic art was ahead of its time when it was created, new implementations like OpenAI’s DALL-E AI image generator are pushing the boundaries of what’s possible with artificial intelligence. 

What Is Google DeepDream and What Are Its Applications?

Google DeepDream was first introduced in 2015, and is part of a broader trend in machine learning, called "neural style transfer," where a neural network is used to generate images with the same content but a different style. 

For instance, you could use a neural network to transform a photo of a sunset into an oil painting. DeepDream specifically applies this concept to image recognition–it takes an image and changes it so that a computer can easily identify the objects in that image. 

The end result is often an image that has been distorted or "dreamed up" by the computer. DeepDream can create "dreamy" or "trippy" images, and has been considered one of the first uses of AI to create art. This might sound like a pointless tool, but it is actually useful. Google, for example, has used DeepDream to improve its image search results. By making images easier for computers to understand, DeepDream can help Google's algorithms better identify the objects in these images and return more relevant search results.

How Does Google DeepDream Work?

DeepDream works by taking an image and then passing it through a neural network. This neural network has been trained to recognise certain visual patterns, such as shapes or colours. As the image passes through the neural network, the program looks for these patterns and changes the image to make that pattern more noticeable. Then, the pattern is repeated over and over, becoming more and more pronounced. The end result is an exaggerated image "dreamed up" by the computer.

If you are unclear about neural networks, here is a quick explanation: a neural network is a computer program designed to mimic the way the human brain works. It is made up of a series of nodes, or "neurons," which are all interconnected. Each node has a few connections to other nodes, and they can be either positive or negative. When you present an image to the neural network, it passes through the nodes. If the input is positive, it will strengthen the connection between that node and the next node. If the input is negative, it will weaken the connection.

This process is then repeated until the neural network has either found the pattern it is looking for or decides the pattern is not there.

How Can I Try Google DeepDream?

If you are interested in trying Google DeepDream for yourself, there are two ways to do so. The first is to use an online service, such as Dreamscope or DeepDream Generator. These services allow you to upload an image and then generate a DeepDream version of that image. The second option is to use the DeepDream code Google released on GitHub–your computer can run this code, but it is a bit more complicated than using an online service.

Both methods allow you to use machine learning to create art that can be sold as NFTs. Another way to create AI art is to use our text-to-image generator, which uses AI to convert simple text prompts, like "a fox under the moon," into digital paintings with just a click. 

What Are Some Limitations of Google DeepDream?

Although DeepDream is an exciting advancement in machine learning, it has some limitations. One major limitation is that it can only be used with certain types of images. Specifically, it works best with images with a lot of detail and patterns.

Another issue with DeepDream is that it can sometimes produce hard-to-understand images. This is because the same rules do not apply to it as they do to the human brain. DeepDream can detect patterns that we cannot, and as a result, it can create images that may be bizarre, confusing, or unsettling to us.
