I already trained few models from tf model zoo. I did over 100k steps on ssd mobilenet v1 and faster rcnn resnet 101. Problem with ssd is that it won't converge. Loss is not getting below stable 2 and accuracy is bad. Problem with faster rcnn is that loss is below 1 but it's varying a lot and sometimes it jumps over 1. What I've done New TF OD API. New TF2 OD API introduces eager execution that makes debugging of the object detection models much easier; it also includes new SOTA models that are supported in the TF2 Model Zoo. Good news for Tensorflow 1.x. users is that the new OD API is backward compatible, so you can still use TF1 if you like, although switching to TF2 is highly recommended

A summary of the steps for optimizing and deploying a model that was trained with the TensorFlow* framework: Configure the Model Optimizer for TensorFlow* (TensorFlow was used to train your model).; Freeze the TensorFlow model if your model is not already frozen or skip this step and use the instruction to a convert a non-frozen model.; Convert a TensorFlow* model to produce an optimized. The model we shall be using in our examples is the SSD ResNet50 V1 FPN 640x640 model, since it provides a relatively good trade-off between performance and speed. However, there exist a number of other models you can use, all of which are listed in TensorFlow 2 Detection Model Zoo Tensorflow Model Zoo and Jetson Nano. Autonomous Machines.

The first galaxy was observed by a Persian astronomer Abd al-Rahman over 1,000 years ago, and it was first believed to be an unknown extended structure. which is now known as Messier-31 or the infamous Andromeda Galaxy. From that point on, these unknown structures are more frequently observed and. TensorFlow Fully Convolutional Neural Network. Let's start with a brief recap of what Fully Convolutional Neural Networks are. Fully connected layers (FC) impose restrictions on the size of model inputs. If you have used classification networks, you probably know that you have to resize and/or crop the image to a fixed size (e.g. 224×224)
Image Classification is a method to classify the images into their respective category classes. CIFAR-10 Dataset as it suggests has 10 different categories of images in it. There is a total of 6000 images of 10 different classes naming Airplane, Automobile, Bird, Cat, Deer, Dog, Frog, Horse, Ship, Truck. All the images are of size 32×32 Image Classification is one of the fundamental supervised tasks in the world of machine learning. TensorFlow's new 2.0 version provides a totally new development ecosystem with Eager Execution enabled by default. By me, I assume most TF developers had a little hard time with TF 2.0 as we were habituated to use tf.Session and tf.placeholder that we can't imagine TensorFlow without The model accepts a 1-D float32 Tensor or NumPy array of length 15600 containing a 0.975 second waveform represented as mono 16 kHz samples in the range [-1.0, +1.0]. Outputs The model returns a 2-D float32 Tensor of shape (1, 521) containing the predicted scores for each of the 521 classes in the AudioSet ontology that are supported by YAMNet
