在这项工作中，我们提出了Cluda，这是一种简单而又新颖的方法，用于通过将对比损失纳入学生教师学习范式中，以进行语义分割，以进行语义分割，以利用伪标记，以通过伪标记产生的伪标记。教师网络。更具体地说，我们从编码器中提取多级融合功能图，并通过图像的源目标混合使用不同类别和不同域的对比度损失。我们始终提高各种特征编码器体系结构和语义分割中不同域适应数据集的性能。此外，我们引入了一种学识渊博的对比损失，以改善UDA最先进的多分辨率训练方法。我们在gta $ \ rightarrow $ cityScapes（74.4 miou，+0.6）和Synthia $ \ rightarrow $ cityScapes（67.2 miou，+1.4）数据集上产生最先进的结果。 Cluda有效地证明了UDA中的对比度学习是一种通用方法，可以轻松地将其集成到任何现有的UDA中以进行语义分割任务。有关实施的详细信息，请参考补充材料。

Autonomous driving requires efficient reasoning about the location and appearance of the different agents in the scene, which aids in downstream tasks such as object detection, object tracking, and path planning. The past few years have witnessed a surge in approaches that combine the different taskbased modules of the classic self-driving stack into an End-toEnd(E2E) trainable learning system. These approaches replace perception, prediction, and sensor fusion modules with a single contiguous module with shared latent space embedding, from which one extracts a human-interpretable representation of the scene. One of the most popular representations is the Birds-eye View (BEV), which expresses the location of different traffic participants in the ego vehicle frame from a top-down view. However, a BEV does not capture the chromatic appearance information of the participants. To overcome this limitation, we propose a novel representation that captures various traffic participants appearance and occupancy information from an array of monocular cameras covering 360 deg field of view (FOV). We use a learned image embedding of all camera images to generate a BEV of the scene at any instant that captures both appearance and occupancy of the scene, which can aid in downstream tasks such as object tracking and executing language-based commands. We test the efficacy of our approach on synthetic dataset generated from CARLA. The code, data set, and results can be found at https://rebrand.ly/APP OCC-results.
