I am running confusion matrix on my own custom model using Tensorflow Object Detection API. I am using Faster R-CNN Inception v2 pets. I get this output:
Processed 100 images
Processed 200 images
Processed 300 images
Processed 400 images
Processed 500 images
Processed 500 images
Confusion Matrix:
[[1281. 233.]
[ 581. 0.]]
category precision_@0.5IOU recall_@0.5IOU
0 person 0.68797 0.846103
From this matrix:
[[1281. 233.]
[ 581. 0.]]
Which one is true positive, true negative, false positive, false negative?
I am using code from this github . It said that this link would provide more explanation about this code, but the post went missing. So, i am confused.
Also, can i calculate accuracy from this results? Sorry if i'm wrong.
Please check below image.
More information about confusion matrix can be found here. https://www.analyticsvidhya.com/blog/2020/04/confusion-matrix-machine-learning/
True positive: 1281 True negative: 0. False Negative: 581. False Positive: 233.
Confussion matrix is a performance measurement for machine learning classification problem where output can be two or more classes or simplify we can assume CM calculate accuracy/loss your model.
