pooling layers, and fully connected layers, and it uses a backpropagation algorithm to learn spatial hierarchies of data automatically and adaptively. You will learn more about these terms in the following section.
The Nvinfer configuration file is used in the nvinfer plugin; see theDeepstream plugin manualfor more details. The following are key parameters for running the MaskRCNN model: uff-file=<PathtoMRCNNuffmodel>parse-bbox-instance-mask-func-name=<postprocessparsername>custom-lib-path=<pathtopostproc...
Despite the advantages of the Fast R-CNN model, there is a critical drawback as it depends on the time-consuming Selective Search algorithm to generate region proposals. The Selective Search method cannot be customized on a specific object detection task. Thus, it may not be accurate enough to...

Faster R-CNNis an object detection algorithm proposed byShaoqing Ren, Kaiming He, Ross Girshick, and Jian Sunin 2015. The research paper is titled 'Faster R-CNN: Towards Real-Time Object Detection with Region Proposal Networks', and is archived athttps://arxiv.org/abs/1506.01497. Faster R...
Gradient Descent or Gradient-based learning algorithm: To minimize the training error, this algorithm repetitively updates the network parameters through every training epoch. More specifically, to update the parameters correctly, it needs to compute the objective function gradient (slope) by applying a...
Adam [99] (short for Adaptive Moment Estimation) was also used as an optimization algorithm for training machine learning models, particularly neural networks. It is an extension of stochastic gradient descent (SGD) and is designed to optimize the learning process by adapting the learning rates of...
The Faster RCNN .onnx` file generated from tao model export is taken as an input to tao deploy to generate optimized TensorRT engine. For more information about training the Faster RCNN, please refer to Faster RCNN training documentation....
-b: The batch size used during the export step for INT8 calibration cache generation (default:8) -m: The maximum batch size for the TensorRT engine. The default value is16. If you encounter out-of-memory issues, decrease the batch size accordingly. This parameter is only useful for.etlt...
Then the other direction was a revival of neural networks — a particular kind of learning algorithm first explored in the 1950s and 1960s that drew inspiration from the network of neurons in the human brain. But they were extremely limited in what they could do. In the late 1980s, we ...
