NEXYAD Data Aggregation Platform and Applications

SafetyNex aggregates all available data onboard, in real time, and provides 20 times per second a level of driving caution, of driving risk and a maximum speed to keep driving behavior cautious enough regarding context.

Driving-Risk Assessment

SafetyNex

SafetyNex is a real time onboard data aggregation platform that takes every source of data available in the vehicle and generates 3 outputs, in real time during driving (20 times per second) :
. level of caution in driving, taking account both of driving behavior and driving context
. level of driving risk ( = lack of caution )
. maximum speed not to exceed in order to keep a good level of caution in driving
This is used for driving coach (after market or new vehicle), for intelligent ACC (that modulates speed to stay cautious in any situation), and for controler of AD system (making AD « aware » of the risk it takes)

Visibility Measurement

Visibility Measurement

VisiNex measures visibility and detects any lack of visibility (fog, rain, snow, sand, smoke, darkness, …). It can be used for hazard warning and as a risk factor for SafetyNex (optional input to take into account visibility in the driving risk assessment).
It also can be used to detect dust on ADAS cameras. VisiNex is also an optional input to ADAS computer vision detection systems: e.g. a detection of obstacles (pedestrians, cars, …) by computer vision may use the characteristics of visibility (provided by SafetyNex to “learn” how the aspect of an object (e.g. a car) is modified with a given lack of visibility (e.g. fog).
It allows to extend detection good performance under bad visibility conditions.

Those modules may be recompiled on any chip and architecture.
NEXYAD also proposes special optimizations for customers hardware on demand.
Those 4 modules are hybrid Artificial Intelligence: physics, algorithms, knowledge based system, deep learning, neural gas, signal theory, possibility theory, … They run very fast on classical chips.
We are currently working on making them SIL approved.

Artificial Intelligence and Applied Maths software tools and methods

NEXYAD has been developing a software development environment that is for sure one of the best development environment in the world. It guaranties a high quality level of all our products.

NxMagic: builds automatically a hybrid deep learning & computer vision algorithms based solution from a labelled images database. Testing more than 250,000 feature extractions from images and videos, automatically selecting the N (e.g. N=20) best non correlated features, building several Neural Networks architectures automatically, and training them. Result is the best automatic solution, starting point of our engineering work (gain of time I estimated > 6 month to 1 year on complex pattern recognition tasks).
Note: our deep learning is homemade and beats TensorFlow (see benchmarks in “News”).

NxData: software implementation of the methodology AGENDA (Approche Générale des Etudes Neuronales pour le Développement d’Applications) published in scientific papers by NEXYAD founders. This methodology aims, among other things, to write formal specifications of learning and test databases. Result is much smaller databases with a much performant and robust deep learning result.

NxDeveloper: the “great link” program of our development environment that includes:
. a NEXYAD script language for very fast R&D and tests of leads
. HMI
. program interfaces
. workspace

NxObject: a collection of C++ objects with more than 3,000 algorithms and methods for applied maths, data analysis, signal processing, computer vision, image processing, decision making, artificial intelligence (machine learning and knowledge based systems), used and reused into dozens of projects then fully debugged.

NxAtelier: extract of NxObject specialized in visibility measurement. Connected to a physical test bench system used to calibrate cameras. After calibration VisiNex (visibility measurement) can run on any decent automotive camera and lead to exactly the same results.

NxNeural: it is a part of NxObjects interfaced within Microsoft Excel to apply our deep learning, and data analytics methods without programming (useful for Data Scientists)

Encapsulation: of our real time AI module SafetyNex into applications environments: Android Java, iOS Objective C, Linux C, Windows C, to simplify work of integrators.

Asynchronous real time replay architecture with: MAP data, timestamped sensors data and images, … using the framework RTMaps (proposed by the company INTEMPORA). This complete asynchronous real time replay environment is used to recreate bugs encountered by customers, analyse and understand them to get them fixed quickly.

This unique environment is a key element that generates deserved trust of our customers: we are over state of the art in Artificial Intelligence, and obsessed with source code quality, validation, methodologies: if something works, we know why and how it does. We are also collaborating with specialized companies in SIL (Security Integration Level). And we are agile to develop new real time modules in very short times when needed, always up to date.
