AI to Associate Objects and Spoken Words

MIT scientists believe that this approach will simplify the automatic translation between several languages

Scientists from the Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Lab published a report on a new model of machine learning, which is able to compare objects on the image with their voice description. As a basis, the researchers took the work of 2016 and improved it by teaching it to combine certain spectrograms of the voice with certain fragments of pixels. Engineers hope that in the future their model will be useful in simultaneous translation.

The MIT algorithm is based on two convolutional neural networks. The first divides the image into a grid of cells, and the second composes a voice spectrogram - a visual representation of the frequency spectrum - and also breaks it into segments in a single word length. Then the system compares each cell of pixels with a segment of the spectrogram and considers the degree of similarity. Based on this parameter, the neural network determines which pair "object-word" is correct and which is not.

We wanted to do speech recognition in a way that’s more natural, leveraging additional signals and information that humans have the benefit of using, but that machine learning algorithms don’t typically have access to.

After studying the database of 400,000 images, the system was able to match several hundred words with objects. After each iteration, it narrowed the matching parameter to determine specific words associated with specific objects.

MIT believes that this approach will simplify the automatic translation between several languages, since it does not require a text description of objects.

Image recognition systems and voice are already coping with their task, but they require a lot of resources for this. In April 2018, Google announced a development competition in the field of deep networks and computer vision on smartphones. It is designed to find ways to optimize the operation of real-time recognition systems.

Apple to Acquire Drive.ai

Apple's decision came just in time - management of self-driving car startup was going to lay off a lot employees on Friday, 28.06

Apple confirmed to Axios and The Verge that it bought a startup Drive.ai. As you can guess from the name, he developed the system of unmanned vehicle control. In recent times, things have been going badly. The management was going to close the company on Friday and disband the employees.

Drive.ai tested its technology on the redesigned Nissan NV200s - a bright orange car with several LED screens. They displayed messages for passersby and other road users: that the car gives way to a pedestrian, continues to move or turns into a ramp.

According to The Verge, a year ago, Drive.ai was considered one of the most promising startups in its field. It was estimated at 200 million dollars. According to the publications, Apple paid less for a startup.
