Creating Long and High-Resolution Videos with Dual Video Discriminator GAN
The pace of progress in machine learning research has been staggering in the last few years. Neural network-Based learning algorithms are now able to look at an image and describe what is seen in this image, or even better, generate images from a written description. One such image generation technique is BigGAN, which is state-of-the-art.
The next frontier in machine learning research is to generate videos. With the Dual Video Discriminator GAN (DVD-GAN) developed by DeepMind, it is now possible to Create longer and higher-resolution videos than what was previously possible.
Progress of Machine Learning Research
Machine learning research has come a long way in the last few years. With the help of neural network-based learning algorithms, it is now possible to train computers to recognize objects in images, detect faces, and even play games like Go and Chess better than humans. These algorithms have also been used in the development of self-driving cars, personalized medicine, and financial forecasting.
Image Generation with Neural Network
GAN is an abbreviation for Generative Adversarial Network, which is a pair of neural networks that battle each over time to master a task, for instance, to generate realistic-looking images when given a theme. These networks learn through a process of trial and error, where one network tries to generate realistic images that can fool the other network into thinking that they are real.
The Role of GAN in Image Generation
BigGAN is one of the most advanced image generation techniques that use GAN. It is possible to create precise and detailed synthetic images with BigGAN. However, BigGANs cannot generate synthetic videos.The Dual Video Discriminator GAN (DVD-GAN) developed by DeepMind solves this problem.
Dual Video Discriminator GAN (DVD-GAN)
The DVD-GAN is a more powerful version of the GAN algorithm specially designed for video generation. It uses two discriminators, spatial, and temporal to create realistic and high-quality videos.
Creation of Longer and High-Resolution Videos
The DVD-GAN can create longer and high-resolution videos than was previously possible. The highest resolution for the generated video is 256x256, with 48 frames or about 2 seconds of video duration. This opens up new frontiers in video generation research.
Understanding of Camera View and Object Drawing
The DVD-GAN has the ability to understand the concept of changes in camera view, zooming in on an object, and drawing objects with a pen.
The Concept of Dual Discriminator
In a classical GAN, we have a discriminator network that looks at the images of the generator network and critiques them. In this work, we have not one, but two discriminators, one-called space, and another called temporal.
The Spatial Discriminator
The spatial discriminator looks at just one image and assesses how good it is structurally. It provides information on the quality of the image generated by the generator network.
The Temporal Discriminator
The temporal discriminator critiques the quality of the movement in these videos. This additional information provides better teaching for the generator, which will in return, be able to generate better videos for us.
Details of the Algorithm
The paper contains all the details that You could possibly want to learn about this algorithm. Interesting features of this algorithm include, firstly, it does not receive additional information about where the foreground and the background is, yet it can learn to differentiate between the two. Secondly, it does not generate the video frame by frame sequentially, but it creates the entire video in one go.
Wild Features of DVD-GAN
The DVD-GAN is an excellent advancement in machine learning research. It has opened up new possibilities in video generation research. However, the resolution of the generated video is limited to 256x256, which is not high enough for practical application.
Possibility of Higher Video Resolution
The scientist behind this invention believes that in the future, this algorithm can generate HD videos that are also longer than we have the patience to watch.Some followup works could be done to refine the algorithm and improve the resolution.
Conclusion
The DVD-GAN algorithm is an impressive advancement in machine learning research. It opens up new frontiers in video generation research. The algorithm provides the possibility of creating longer and higher-resolution videos. With the continuous progress in machine learning research, the future holds the possibility of generating ultra-high-resolution videos. The DVD-GAN is an incredible Stride towards that future.
