Predictive Cruise Control Using Radial Basis Function Network-Based Vehicle Motion Prediction and Chance Constrained Model Predictive ControlCache
|Title: Predictive Cruise Control Using Radial Basis Function Network-Based Vehicle Motion Prediction and Chance Constrained Model Predictive Control
Authors: Yoon, Seungje; Jeon, Hyeongseok; Kum, Dongsuk
Abstract: Predicting future motions of surrounding vehicles and driver's intentions are essential to avoid future potential risks. The predicting future motions, however, is very challenging because the future cannot be deterministically known a priori and there are infinitely many possible future trajectories. Prediction becomes far more challenging when trying to foresee distant future. This paper proposes a probabilistic motion prediction algorithm that can accurately compute the likelihood of multiple target lanes and trajectories of surrounding vehicles by using the artificial neural network; more specifically radial base function network (RBFN). The RBFN prediction algorithm estimates the likelihood of each lane being the driver's target lane in categorical distributions and the corresponding future trajectories in parallel. In order to demonstrate the effectiveness of the proposed prediction algorithm, it is applied for the predictive cruise control problem. Chance-constrained model predictive control (CCMPC) is utilized because the chance constraints in CCMPC can handle collision uncertainties associated with future uncertainties from the proposed prediction algorithm. The RBFN-based CCMPC simulation is conducted for several risky cut-in scenarios and compared with the state-of-the-art Interactive Multiple Model (IMM)-based prediction algorithm. The simulation results show that the RBFN-based CCMPC achieves higher collision avoidance success rate than that of the IMM-based CCMPC while using smaller actuator inputs and providing higher passenger comforts. Furthermore, the RBFN-based CCMPC showed high robustness to false braking during near lane-change (lane-keeping) scenarios.|

Composed by hundred billion neurons with nonlinearities, the brain consists explicit connection paradigms and exhibits collective dynamics. Also, both high computational flexibility and robustness are crucial for species. How then do biological systems balance the need for both variability and robustness?Mounting evidence suggests that evolution leads neural networks of cerebral cortexto a critical point between order and disorderand yield an optimal trade-off between the robustness and accuracy that biological machinery demands.A rigorous understanding of brain dynamics and function composes multiple levels of organization, suchas neural compartments, neural spiking and network-level population activity. To study thestability of trade-off between robustness and flexibility, we explored whether multi-level neural dynamicschangeor preserveunder visualperturbations and motor learning.We studied neural dynamics under various visual perturbations (visual stimuliand monocular deprivation), and across motor learning in motor cortex.We conducted statistical analysis and used model investigations. We found multiple dynamics changed under perturbation, such as neural connectivity, neural representations, et. al. On network level, criticality either serves as a set-point or constraint. Together, these results contribute to understanding of connection paradigms and collective dynamics in the brain under visual perturbation and motor learning.
The objective of this thesis is to describe the study of cometary materials returned by NASA’s Stardust mission. The majority of the research presented in this thesis focuses on improving our characterization and understanding of the fine (< 1 µm) component of comet Wild 2. Investigations of the Stardust foils are conducted with correlated Scanning Electron Microscopy (SEM), Focused Ion Beam (FIB) sample preparation, and Transmission Electron Microscopy (TEM). Investigations of the Stardust aerogels are conducted with plasma ashing sample preparation followed by detailed characterization of the material with TEM. Additional studies of the Stardust interstellar foils, as well as the use of a Convolutional Neural Network (CNN) to search images of the Stardust foils for impact features, are also presented. As a part of this thesis I have developed a new technique for analyzing the Stardust aerogels through the use of plasma ashing sample preparation. This technique is an improvement upon previous attempts to separate cometary materials from the aerogel through the use of HF vapor etching. Plasma ashing allows for cometary materials trapped within the Stardust aerogels to be deposited directly onto TEM grids allowing for detailed characterization of the cometary material with minimal interference from the aerogel itself. The correlated SEM/FIB/TEM studies of the Stardust foils demonstrated here nearly double the number of Stardust craters that have been elementally and structurally characterized in scientific literature. The crater impactor residues were largely composed of combinations of silicates and iron-nickel sulfides that, following impact, rapidly quenched into amorphous melt layers. Two craters were found to contain signatures of the refractory minerals spinel and taenite, indicating a component of the Wild 2 fines originated in the inner Solar System. However, the lack of crystalline material throughout the crater residues suggests that the fine component may largely be composed of amorphous silicates that likely formed in the outer Solar System. Additionally, the submicron Stardust craters appeared enriched in volatile elements relative to CI chondrites, further suggesting that the fine component of Wild 2 originated from a reservoir that was separate from the more refractory coarse (> 1 µm) component. The Stardust aerogel samples returned carbon-rich and potential oldhamite grains. Carbon-rich materials have not been previously observed in the Stardust foils, likely due to the violent collection methods, and the result suggests the ashing technique may be used to better characterize components of the Wild 2 fines that have been difficult to investigate. The presence of oldhamite in the Stardust aerogels would be scientifically significant as it is formed in highly reducing conditions and has only been identified in enstatite chondrites and enstatite achondrites. As a result, our results may call into question the Warren gap hypothesis, which would prohibit the presence of such highly reduced materials in the outer Solar System at the time that comet Wild 2 accreted.

|Cache||Resumen : Este artículo está relacionado con el diseño experimental e implementación de un vehículo autónomo para el transporte de
mercancías o materias primas en el interior de una industria o comercio. El proyecto fue desarrollado y coordinado por la
Escuela de Ingeniería Eléctrica y Electrónica de ITCA-FEPADE. Este vehículo es accionado a través de un conjunto de sensores,
tales como infrarrojos, ultrasónicos y sensor LIDAR; el vehículo es capaz de detectar su entorno, y basados en ellos, alcanzar
su destino mediante decisiones de un Raspberry, que, ejecutando un programa basado en red neuronal da las instrucciones a
un microcontrolador Arduino, el cual impulsa los motores eléctricos utilizando una etapa de potencia basada en transistores
MOSFETs. La red neuronal es un tipo de control adaptativo, que viene a sustituir a los controladores tradicionales; al igual
que el ser humano, la red neuronal debe ser entrenada para un funcionamiento óptimo utilizando inteligencia artificial, tal
como el método de retropropagación, en la cual la red neuronal aprende de manera supervisada, en base a patrones de
entrada y salidas conocidas. El vehículo es capaz de transportar un peso de hasta 30 Kg y las tareas de carga y descarga
serán realizadas por un operador humano. Debido a los componentes electrónicos a bordo del vehículo, se recomienda su
operación en ambientes secos y una superficie plana. El nivel de autonomía del vehículo, se refiere a transportar la carga de
un punto a otro sin acción humana directa durante su desplazamiento. Entre los campos de aplicación, se puede considerar
el área logística e industrial, para el transporte de materia prima, herramientas, componentes electrónicos, telas y alimentos
enlatados, entre otros.

The Importance of Space and Time for Signal Processing in Neuromorphic Agents: The Challenge of Developing Low-Power, Autonomous Agents That Interact With the EnvironmentCache
|Artificial neural networks (ANNs) and computational neuroscience models have made tremendous progress, enabling us to achieve impressive results in artificial intelligence applications, such as image recognition, natural language processing, and autonomous driving. Despite this, biological neural systems consume orders of magnitude less energy than today's ANNs and are much more flexible and robust. This adaptivity and efficiency gap is partially explained by the computing substrate of biological neural processing systems that is fundamentally different from the way today?s computers are built. Biological systems use in-memory computing elements operating in a massively parallel way rather than time-multiplexed computing units that are reused in a sequential fashion. Moreover, the activity of biological neurons follows continuous-time dynamics in real, physical time instead of operating on discrete temporal cycles abstracted away from real time.|
|Cache||Inventors of the original artificial neural networks (ANNs) derived their inspiration from biology . However, today, most ANNs, such as backpropagation-based convolutional deeplearning networks, resemble natural NNs only superficially. Given that, on some tasks, such ANNs achieve human or even superhuman performance, why should one care about such dissimilarity with natural NNs? The algorithms of natural NNs are relevant if one's goal is not just to outperform humans on certain tasks but to develop general-purpose artificial intelligence rivaling that of a human. As contemporary ANNs are far from achieving this goal and natural NNs, by definition, achieve it, natural NNs must contain some "secret sauce" that ANNs lack. This is why we need to understand the algorithms implemented by natural NNs.|

We present a new loss function, namely Wing loss, for robust facial landmark localisation with Convolutional Neural Networks (CNNs). We first compare and analyse different loss functions including L2, L1 and smooth L1. The analysis of these loss functions suggests that, for the training of a CNN-based localisation model, more attention should be paid to small and medium range errors. To this end, we design a piece-wise loss function. The new loss amplifies the impact of errors from the interval (-w, w) by switching from L1 loss to a modified logarithm function. To address the problem of under-representation of samples with large out-of-plane head rotations in the training set, we propose a simple but effective boosting strategy, referred to as pose-based data balancing. In particular, we deal with the data imbalance problem by duplicating the minority training samples and perturbing them by injecting random image rotation, bounding box translation and other data augmentation approaches. Last, the proposed approach is extended to create a two-stage framework for robust facial landmark localisation. The experimental results obtained on AFLW and 300W demonstrate the merits of the Wing loss function, and prove the superiority of the proposed method over the state-of-the-art approaches.

Reported by Science Daily 33 minutes ago.
In optoacoustics, image quality depends on the number and distribution of sensors used by the device; the more sensors and the more broadly they are arranged, the better the quality.
To improve image quality in low-cost optoacoustic devices with only a small number of ultrasonic sensors, researchers at ETH Zurich and the University of Zurich turned to machine learning. They developed a framework for the efficient recovery of image quality from sparse optoacoustic data using a deep convolutional neural network and demonstrated their approach with whole body mouse imaging in vivo.
To generate accurate, high-resolution reference images for training, the team began by developing a high-end optoacoustic scanner with 512 sensors. An...
Supervised learning for distribution of centralised multiagent patrolling strategies. , lundi 18 novembre à 14h.Cache
|For nearly two decades, patrolling has received significant attention from the multiagent community. Multiagent patrolling (MAP) consists in modelling a patrol task to optimise as a multiagent system. The problem of optimising a patrol task is to distribute agents over the area to patrol in space and time the most efficiently, which constitutes a decision-making problem. A range of algorithms based on reactive, cognitive, reinforcement learning, centralised and decentralised strategies, among others, have been developed to make such a task ever more efficient. However, the existing patrolling-specific approaches based on supervised learning were still at preliminary stages, although a few works addressed this issue. Central to supervised learning, which is a set of methods and tools that allow inferring new knowledge, is the idea of learning a function mapping any input to an output from a sample of data composed of input-output pairs; learning, in this case, enables the system to generalise to new data never observed before. Until now, the best online MAP strategy, namely without precalculation, has turned out to be a centralised strategy with a coordinator. However, as for any centralised decision process in general, such a strategy is hardly scalable. The purpose of this work is then to develop and implement a new methodology aimed at turning any high-performance centralised strategy into a distributed strategy. Indeed, distributed strategies are by design resilient, more adaptive to changes in the environment, and scalable. In doing so, the centralised decision process, generally represented in MAP by a coordinator, is distributed into patrolling agents by means of supervised learning methods, so that agents of the resultant distributed strategy tend to capture each a part of the algorithm executed by the centralised decision process. The outcome is a new distributed decision-making algorithm based on machine learning. In this thesis therefore, such a procedure of distribution of centralised strategy is established, then concretely implemented using some artificial neural networks architectures.|

Recently, they have also been used in Art and design to stylise photographs guided by artworks of various artists. However, such stylisation mostly concentrates on the texture and the colour of the artworks. In this work we try to capture the Geometric style of artists using neural networks. We concentrate on portraits and propose a new method for landmark detection in paintings that allow us to analyse and capture geometric deformations in face paintings, and define a geometric style for artists. We demonstrate our technique by creating average portraits for Artists as well as defining a geometry-aware portrait stylisation algorithm. This work was published in SIGGRAPH 2019 and is joint work with Jordan Yaniv and Yael Newman. See http://www.faculty.idc.ac.il/arik/site/foa/face-of-art.asp
