对于自动驾驶汽车而言，遍历交叉点是一个具有挑战性的问题，尤其是当交叉路口没有交通控制时。最近，由于其成功处理自动驾驶任务，深厚的强化学习受到了广泛的关注。在这项工作中，我们解决了使用新颖的课程进行深入增强学习的问题的问题。拟议的课程导致：1）与未经课程训练的代理人相比，增强剂学习代理的更快的训练过程和2）表现更好。我们的主要贡献是两个方面：1）提供一个独特的课程，用于训练深入的强化学习者，2）显示了所提出的课程在未信号的交叉遍历任务中的应用。该框架期望自动驾驶汽车的感知系统对周围环境进行了处理。我们在Comonroad运动计划模拟器中测试我们的TTTERTIONS和四向交集的方法。

Linear-quadratic regulators (LQR) are a well known and widely used tool in control theory for both linear and nonlinear dynamics. For nonlinear problems, an LQR-based controller is usually only locally viable, thus, raising the problem of estimating the region of attraction (ROA). The need for good ROA estimations becomes especially pressing for underactuated systems, as a failure of controls might lead to unsafe and unrecoverable system states. Known approaches based on optimization or sampling, while working well, might be too slow in time critical applications and are hard to verify formally. In this work, we propose a novel approach to estimate the ROA based on the analytic solutions to linear ODEs for the torque limited simple pendulum. In simulation and physical experiments, we compared our approach to a Lyapunov-sampling baseline approach and found that our approach was faster to compute, while yielding ROA estimations of similar phase space area.

我们介绍RealityTalk，该系统通过语音驱动的互动虚拟元素来增强实时实时演示。增强演示文稿利用嵌入式视觉效果和动画来吸引和表现力。但是，现有的实时演示工具通常缺乏互动性和即兴创作，同时在视频编辑工具中产生这种效果需要大量的时间和专业知识。RealityTalk使用户能够通过实时语音驱动的交互创建实时增强演示文稿。用户可以通过实时语音和支持方式进行交互提示，移动和操纵图形元素。根据我们对177个现有视频编辑的增强演示文稿的分析，我们提出了一套新颖的互动技术，然后将它们纳入真人秀。我们从主持人的角度评估我们的工具，以证明系统的有效性。

语音触发检测是一项重要的任务，它可以在目标用户说关键字短语时激活语音助手。通常对探测器进行语音数据培训，独立于说话者信息，并用于语音触发检测任务。但是，这样的说话者独立语音触发探测器通常会遭受绩效降低，因为代表性不足的群体，例如重音说话者。在这项工作中，我们提出了一个新颖的语音触发探测器，该触发探测器可以使用目标扬声器中的少量话语来提高检测准确性。我们提出的模型采用编码器架构。尽管编码器执行扬声器独立语音触发检测，但类似于传统检测器，解码器预测了每种话语的个性化嵌入。然后，获得个性化的语音触发分数作为在注册话语的嵌入与测试话语之间的相似性得分。个性化的嵌入允许在计算语音触发评分时适应目标扬声器的语音，从而提高语音触发检测精度。实验结果表明，与基线扬声器独立语音触发模型相比，所提出的方法相对降低（FRR）的相对降低38％。

Virtual assistants such as Google Assistant, Alexa and Siri provide a conversational interface to a large number of services and APIs spanning multiple domains. Such systems need to support an ever-increasing number of services with possibly overlapping functionality. Furthermore, some of these services have little to no training data available. Existing public datasets for task-oriented dialogue do not sufficiently capture these challenges since they cover few domains and assume a single static ontology per domain. In this work, we introduce the the Schema-Guided Dialogue (SGD) dataset, containing over 16k multi-domain conversations spanning 16 domains. Our dataset exceeds the existing task-oriented dialogue corpora in scale, while also highlighting the challenges associated with building large-scale virtual assistants. It provides a challenging testbed for a number of tasks including language understanding, slot filling, dialogue state tracking and response generation. Along the same lines, we present a schema-guided paradigm for task-oriented dialogue, in which predictions are made over a dynamic set of intents and slots, provided as input, using their natural language descriptions. This allows a single dialogue system to easily support a large number of services and facilitates simple integration of new services without requiring additional training data. Building upon the proposed paradigm, we release a model for dialogue state tracking capable of zero-shot generalization to new APIs, while remaining competitive in the regular setting.
