BN所以不用考虑这个问题,如果是VGGNet这种没有BN的网络为什么效果也不好呢,我的观点是还是batch size太小的问题,我觉得大家有一个很常见的误区是把classification和detection完全分割开来对待,对于training from scratch,我觉得他们完全是相近的,我们可以想象如果ImageNet上用很小的batch size训clas
, a fast, real-time object detection algorithm that is widely used in the field of computer vision. It is capable of detecting multiple objects in an image and assigning them semantic labels based on their class. The following image is an example of the output of an object detection model:...
of-the-art performance. In this work, we contribute a set of design principles for this purpose. One of the key findings is the deeply supervised structure enabled bydense layer-wise connections, plays a critical role in learning a good detection model. Please see our paper for more details...

Training an object detection model from scratch doesn’t provide a lot of benefit when pre-trained models exist.Transfer learninglets usfine-tunea model that already understands objects. I usedDETR (Detection Transformer), a transformer-based object detection modelfrom Facebook AI. It learns...
Image Credits: Karol Majek. Check out his YOLO v3 real time detection videohere This is Part 4 of the tutorial on implementing a YOLO v3 detector from scratch. In the last part, we implemented the forward pass of our network. In this part, we threshold our detections by an object ...
Training an object detection model can be resource intensive and time-consuming. This tutorial shows you it can be as simple as annotation 20 images and run a Jupyter notebook on Google Colab.
Rethinking Training from Scratch for Object Detection 一. 概述 正常训练目标检测的流程分为以下几种: 在imagenet上进行预训练,然后在特定数据集进行tune 直接在数据集上进行从头训练 两种方式各有千秋,前者可以很快收敛(在特定数据集收敛快),但是训练复杂(预训练实际长)。后者直接训练较为容易(尤其在修改模型结构时...
A while back you have learned how to train an object detection model with TensorFlow object detection API, and Google Colab's free GPU, if you haven't, check it out in the post. The models in TensorFlow object detection are quite dated and missing updates for the state of the art ...
Training a model from scratch: To train a deep network from scratch, you gather a very large labeled dataset and design a network architecture that will learn the features and build the model. The results can be impressive, but this approach requires a large amount of training data, and you...
