A Day in the Life of a Machine Learning Engineer: What do they do? Radar is usually more robust than the camera in severe driving scenarios, e. g., weak/strong lighting and bad weather. A good training session will have moderate (~ 0.5) and relatively stable losses for the unsupervised discriminator and generator while the supervised discriminator will converge to a very low loss (< 0.1) with high accuracy (> 95%) on the training set. Next, we implement a vanilla SpectraNet and show its promising performance on moving object detection and classification with a mean average precision (mAP) of 81.9% at an intersection over union (IoU) of 0.5. _____ Some of the algorithms and projects I . Detectron2. The "trained" radar was able to differentiate between four human motions (walking, falling, bending/straightening, sitting). More work is required to match or exceed the ~ 90% accuracy obtained by SVM and Logistic Regression models in previous work [8][9]. To overcome the lack of radar labeled data, we propose a novel way of making use of abundant LiDAR data by transforming it into radar-like point cloud data and aggressive radar augmentation techniques. Projections from a typical single sample are shown in the heat map visualization below. Whereas, the deep learning approach makes it possible to do the whole detection process without explicitly defining the features to do the classification.
