If you leave something like this (https://lambdalabs.com/deep-learning/workstations/4-gpu/basic/customize) running 24/7 you can produce about 50 orange points a week on COCO. What do you mean? If you will find mistake in my code or pycocotool, let me know ). How to calculate mAP for (Gaussian+GIOU+YOLOv3) in this repository? They must change depending on image size, as well as class count, and occupancy (how many objects per image).

Neural networks have enabled state-of-the-art approaches to achieve incredible results on computer vision tasks such as object detection. Or if you train with flag -map then you will see mAP indicator Last accuracy mAP@0.5 = 18.50% in the console - this indicator is better than Loss, so train while mAP increases.

@WongKinYiu yes we have an automatic hyperparameter search method. 提升分辨率:416--> 608等必须是32倍数. You can, YOLOv4: Optimal Speed and Accuracy of Object Detection, Real-Time Object Detection You should run detector test command with flag -thresh 0.001 as it is done for mAP-calculation by default: There is solved this issue: #2140 (comment). • AlexeyAB/darknet 前言的前言:Darknet是一个较为轻型的完全基于C与CUDA的开源深度学习框架,其主要特点就是容易安装,没有任何依赖项(OpenCV都可以不用),移植性非常好,支持CPU与GPU两种计算方式。而AlexeyAB版本的Darknet是在… Real-Time Object Detection Screenshot with info: I have tried to not ignore iscrowd boxes, and not filtering using maxDets on pycocotools, while using same thresh=0.001 and same get_network_boxes parameters for valid and map on darknet (used -letter_box option in the command), but still not able to get same map@IoU=0.5. they're used to log you in. mAP@0.5 - mAP for IoU_threshold = 0.5. @AlexeyAB Hi, I trained yolov3-spp.cfg and yolov3-spp-gs.cfg in my Custom Data, the yolov3-spp-gs.cfg just replaced [yolo] to [Gaussian yolo]. Three some video results, extract code :xqxu

@tand826 Unfortunately I didn't got time to further look into this. As opposed to scale_x_y=1.05 , 1.1, 1.2 in the different layers?

How many training and test images do you have?



Or you can add different values for different yolo-layers: scale_x_y=1.05 (for 17x17) , 1.1 (34x34) 1.2 (68x68). darknet.exe detector map... 建议训练的时候带上-map,可以画图. I'm currently trying out Gaussian_yolo_spp_swish... Also try then to add params to each of [Gaussian_yolo] layer and train.

you calculated the results from validate_detector_map and test_detector(inference) functions are the same, right?
The highest fitness offspring is in blue. Can you provide URL to article/paper? This change boosted mAP by about 0.07 to 0.47. yolov3+Gaussian+CIoU gets a 0.77% improvement in mAP and a 4% improvement in Recall compared to yolov3. I am getting 54.37 % mAP for COCO-Val set.

Then compare Precision and Recall for one of classes between Darknet and Pycocotool (but not for person-class to avoid crowd issue).

Is my understanding correct?



So for example obj loss = mean(obj_loss_yolo_layer1) + mean(obj_loss_yolo_layer2) + mean(obj_loss_yolo_layer3).

Cannot find the paper you are looking for?

I've tried using anchors generated from using calc_anchorsas suggested, but it just improves a bit. 12,723. I added GIoU to the [Gaussian_yolo] layer. Since I found that nms_kind=greedynms beta1=0.6 is not in Gaussian_yolov3_BDD.cfg(this repo),but in coco-ciou.cfg(DIoU-darknet repo) I don't know the reason. Based on the predicted output, it seems that the bounding box is way too big compared to ground truth, but it does sort of being able to detect the location correctly (refer image below).

thresh_calc_avg_iou = 0.25 - is a confidence-threshold (for probability), it is used only for output F1, FN/FP/TP, Precision, Recall, IoU for the specified confidence threshold, iou_thresh = 0.5 is a IoU-threshold, that is used for mAP calculation, it calculates mAP@0.5 by default (iou_thresh = 0.5).

#4147 (comment). @guozhengjin when i used the original framework,i didn't change the burn_in to 2000,maybe this had some affect
