USB-C could soon offer protection against nefarious devices

USB-C could soon offer protection against nefarious devices USB chargers and devices are universally accessible and easy to use, but they come with a host of potential security risks, namely the spread of malware from infected devices, and data leakage should a device fall into the wrong hands. 

Ever think those pictures of delicious food you see on the internet are too good to be true? Nefarious definition is - flagrantly wicked or impious : evil. How to use nefarious in a sentence. Vicious and villainous are two wicked synonyms of Basically, the team developed an AI that can take almost

Given below, is an image showing a comparison between real food and what was created by the AI : It is almost impossible to distinguish which food is The research is in the early stages and the dataset they used has a lot of blurry, low-quality images . They plan to change the dataset and run it to

A team of researchers from Tel-Aviv University developed a neural network capable of reading a recipe and generating an image of what the finished, cooked product would look like. As if DeepFakes weren’t bad enough, now we can’t be sure the delicious food we see online is real.

The Tel-Aviv team, consisting of researchers Ori Bar El, Ori Licht, and Netanel Yosephian created their AI using a modified version of a generative adversarial network (GAN) called StackGAN V2 and 52K image/recipe combinations from the gigantic recipe1M dataset.

Basically, the team developed an AI that can take almost any list of ingredients and instructions, and figure out what the finished food product looks like.

Food tracking comes to Google Assistant with Lifesum

Food tracking comes to Google Assistant with Lifesum You no longer have to pull out your phone (or look at your watch) to track your dietary habits. Lifesum has introduced what it says is the first food tracking app for Google Assistant, making it easier to keep tabs on your eating patterns. If you ate a large meal or grabbed a glass of water, you just have to use your voice to add that to your log. You can also update your body weight, tackle challenges (such as hiding sugary food in your kitchen) and ask for updates on your progress. This won't fit everyone. Lifesum personalizes meal sizes based on your goals, but it's not very specific beyond that.

Who sAId robots couldn’ t be creative ? artificial intelligence ( AI ) is no longer the stuff of science fiction films, and now In a new paper published by NVIDIA researchers, they released photographic portraits completely generated by AI (GAN) but with a twist – none of the people in the images actually exist .

Researcher Ori Bar El told TNW:

[It] all started when I asked my grandmother for a recipe of her legendary fish cutlets with tomato sauce. Due to her advanced age she didn’t remember the exact recipe. So, I was wondering if I can build a system that given a food image, can output the recipe. After thinking about this task for a while I concluded that it is too hard for a system to get an exact recipe with real quantities and with “hidden” ingredients such as salt, pepper, butter, flour etc.

Then, I wondered if I can do the opposite, instead. Namely, generating food images based on the recipes.  We believe that this task is very challenging to be accomplished by humans, all the more so for computers. Since most of the current AI systems try replace human experts in tasks that are

Rare desert snowfall creates a surreal winter wonderland in Arizona

Rare desert snowfall creates a surreal winter wonderland in Arizona You don't normally think of the desert as having a proper "winter," but parts of Arizona and New Mexico got more than a light dusting of snow to start the year. The result is sprawling desert vistas glazed in white, and it’s downright lovely. Snow isn’t entirely out of the ordinary for states like Arizona and New Mexico at this time of year, but it’s certainly not something that happens regularly, and locals wasted no time capturing the surreal sights to share on Twitter and elsewhere. Despite the chilly temperatures, the cacti seem to be handling things just fine.

No, this isn' t a missing person. It's a face generated by a new artificial intelligence on the website ThisPersonDoesNotExist.com. Just in case you needed a reminder of how freakishly good A . I . is becoming at generating realistic images of people.

The researchers also acknowledge, in their white paper, that the system isn’t perfect quite yet:

Why dreams like flying, falling, being chased are so common, and how your brain creates them

Why dreams like flying, falling, being chased are so common, and how your brain creates them Most of us experience these so-called "typical dreams" during our lifetime.

It is worth mentioning that the quality of the images in the recipe1M dataset is low in comparison to the images in CUB and Oxford102 datasets. This is reflected by lots of blurred images with bad lighting conditions, ”porridge-like images” and the fact that the images are not square shaped (which makes it difficult to train the models). This fact might give an explanation to the fact that both models succeeded in generating ”porridge-like” food images (e.g. pasta, rice, soups, salad) but struggles to generate food images that have a distinctive shape (e.g. hamburger, chicken, drinks).

This is the only AI of its kind that we know of, so don’t expect this to be an app on your phone anytime soon. But, the writing is on the wall. And, if it’s a recipe, the Tel-Aviv team’s AI can turn it into an image that looks good enough that, according to the research paper, humans sometimes prefer it over a photo of the real thing.

What do you think?

The team intends to continue developing the system, hopefully extending into domains beyond food. Ori Bar El told us:

AI creates cookbook, AI makes a lot of really horrible sounding recipes that confirm that AI don’ t really know how food work. There’s an endless debate raging involving the future of artificial intelligence, and how it will change the world. At this point, it’s pretty much inevitable that we will have fully functional

We plan to extend the work by training our system on the rest of the recipes (we have about 350k more images), but the problem is that the current dataset is of low quality. We have not found any other available dataset suitable for our needs, but we might build a dataset on our own that contains children’s books text and corresponding images.

These talented researchers may have damned foodies on Instagram to a world where we can’t quite be sure whether what we’re drooling over is real, or some robot’s vision of a souffle`.

It’s probably a good time for us all to go out into the real world and stick our faces in some actual food. You know, the kind created by scientists and prepared by robots.
