Alphabet’s DeepMind to improve the Google Map with AI Technology


DeepMind, the Artificial Intelligence Research department of Alphabet Inc., currently outlined new machine learning technology formulated to make Google Maps more beneficial. Maps have more than a billion users around the world who are relying on the service to plan their travel routes. One of the most central features of the service is its capacity to estimate the probable arrival time, assisting travelers view key information such as how fast they’re going to have to leave to board a train.

DeepMind has partnered up with the sister company Google LLC to minimize discrepancies in arrival time forecasts. Their partnership, the division reported this morning, culminated in a double-digit decrease in the number of discrepancies. In one scenario, the forecast loss decreased by no less than 51%.

DeepMind has accomplished this enhancement by integrating the so-called “path” neural network in Maps to better predict the time of arrival. The graph is a graphical framework that records data points and the association between them in the form of intertwined dots. DeepMind also found that this structure lends itself well to understanding the dynamic essence of road networks.

For example, how a side street jam can spill over to influence traffic on a wider route, said DeepMind engineers Oliver Lange and Luis Perez in a blog post. Since AI can obtain an interconnected view of several road segments and intersections, the model gains the ability to natively anticipate turn-and-go delays, merging delays, and average cross-haul time.

The organization had to solve a variety of technological difficulties before it could start predicting arrival times using its graph neural network. One of the most critical problems was how to train the AI. Developing neural networks requires educating them on simulated data close to the data they are supposed to interpret in the real world. If the AI is to be charged with evaluating giraffe images, it needs to be conditioned on giraffe images.

But in the case of Maps, the procedure was not as straightforward because of variations in the way the streets are designed. An AI qualified to predict the length of road trips would not always be able to do the same for urban roads, and much smaller variations will also trigger problems with precision.

DeepMind addressed the problem by taking advantage of the visual structure of the neural network. Unit engineers structured road data that the AI uses to predict the arrival times in the “Supersegments” even on the basis of a graph layout, much like the AI itself. These Supersegments are versatile enough that DeepMind’s neural network has learned to transcend the discrepancies in training data.

In certain cases, AI analysis carried out by organizations such as Google not only aims to develop their own products but also develops the field as a whole. DeepMind and AI working groups in other tech companies also discuss their findings with the community in scholarly articles.
