Silicon may be at the heart of most gadgets, but it’s not the only semiconductor around.

Gallium nitride has been getting a lot of attention recently for it’s electrical properties, which outperform silicon in a lot of areas.

Gallium nitride has the potential to revolution power systems, including solar, electric vehicles, and even phone chargers.

Beyond that, it’s finding uses in the mobile industry, and could even be used to build ultra fast processors.

But how feasible is any of that, and even if it’s possible, how long will it take? 

Recently, the researchers from MIT introduced a new AI system known as Timecraft that has the capability to synthesize time-lapse videos depicting how a given painting might have been created.

According to the researchers, there are various possibilities and unique combinations of brushes, strokes, colors, etc. in a painting and the goal behind this research is to learn to capture this rich range of possibilities.

Creating the exact same piece of a famous painting can take days even by skilled artists. However, with the advent of AI and ML, we have witnessed the emergence of a number of AI Artists for a few years now. One of the most popular artisanship of AI is the portrait of Edmond Belamy that was created by Generative Adversarial Network (GAN) and sold for an incredible $432,500.

Text-to-speech engines are usually multi-stage pipelines that transform the signal into many intermediate representations and require supervision at each step.

When trying to train TTS end-to-end, the alignment problem arises: Which text corresponds to which piece of sound?

This paper uses an alignment module to tackle this problem and produces astonishingly good sound.

Anyone can simply upload a selfie to the ‘Selfie 2 Waifu’ website to create their own AI-generated waifu-style anime character in seconds.

The AI leverages the release of the new Tensorflow implementation of unsupervised generative network U-GAT-IT, 

For best results, participants are advised to submit a clear passport-style picture with a plain background. Although the site can also generate male anime results, as the name suggests the system generally performs better on female selfies.

“Our model guides the translation to focus on more important regions and ignore minor regions by distinguishing between source and target domains based on the attention map obtained by the auxiliary classifier,” the researchers explain. “These attention maps are embedded into the generator and discriminator to focus on semantically important areas, thus facilitating the shape transformation.”

Deepfakes leverage powerful techniques from machine learning and artificial intelligence to generate visual and audio content with a such a high degree of realism that it has enormous potential to deceive.

This article in Medium explores efforts into research and development into creating countermeasures to such bogus content.

Within recent months, a number of mitigation mechanisms have been proposed and cited with the use of Neural Networks and Artificial Intelligence being at the heart of them. From this, we can distinguish that a proposal for technologies that can automatically detect and assess the integrity of visual media is therefore indispensable and in great need if we wish to fight back against adversarial attacks.

Siraj Raval explores generative modeling technology.

This innovation is changing the face of the Internet as you read this. It’s now possible to design automated systems that can write novels, act as talking heads in videos, and compose music.

In this episode, Siraj explains how generative modeling works by demoing 3 examples that you can try yourself in your web browser.
