I trained a YOLOv7 model in PyTorch. Is there a way to find what anchor locations were used? I can't find anything online that explains a way to do it.

Hi I have trained object detection model using tensorflow 1.14 object detection API, my model is performing well. However, I want to reduce/optimize parameters of model to make it lighter. How can I use pruning on trained model?
Did you check the Pruning guide on the Tensorflow website ?
It has concrete examples on how to prune a model and benchmark the size and performance improvements.
Guys I am trying to look for demo for object detection using YOLOv4 Tiny on every day objects. Therefore I am looking pre-trained model for YOLOv4 Tiny pre-trained on COCO dataset.After hours of searching I am only come across the similar tutorial on training on custom dataset from beginning using google Colab, I couldn't seem to find any pre-trained model for YOLOv4 Tiny model on COCO dataset.Can you give any reference where can I find a such a model?
Also I am trying to implement the model using OpenCV
As it is known that there are several features in the dataset for the machine learning model. Do the dataset that has only pictures also contain features?
As they can't be opened in excel file, do they contain features?
My project is on PLANT DISEASE DETECTION USING DEEP LEARNING and my professor is asking about the features in the dataset.
I don't know what to say.
I don't know if it is the right place to ask such general question in ML (that would be Cross-Validated I guess). That being said:
So do they contain features?
A feature depends on you and what information you would want to retrieve from it. This means to a certain extent, everything "contains" a feature.
picture datas can always be mapped/transformed into observation-variable dataset where your observation is your picture, and the number of variables/features are arbitrary being an 1D array feature describing the variation of each area in each of your images. The greater your vector is,the more efficient your model will be.
Of course, this is just to answer your question about the how-to theorically as you asked. In practice, you'll need some tool to do that, but I am sure you'll find.
Hope it helped.
If the dataset contains only pictures, features are just hidden in those pictures. You need to extract them automatically using a CNNs - Convolutional Neural Networks for example.
Suppose this is your original image
If you visualize the layers of your CNN (the feature maps from the output of the very first layer for example)
Bright areas are the “activated” regions, meaning the filter detected the pattern it was looking for. This filter seems to encode an eye and nose detector.

From that medium story, I took these photos.
The Machine Learning Model I download from Apple's website, can be used to recognise lots of different object through image.
I want to know, say I need to detect all different kinds of trees. Some can be recognised by the model whereas some cannot. Then how would I know how many trees are being trained in this model? in another word, How would I know all the possible tree recognition in this model? How would I find out? Can I decode the model? or parse it or something?
These models are trained on the ImageNet dataset. Here is a list of classes that these models can detect: https://github.com/HoldenCaulfieldRye/caffe/blob/master/data/ilsvrc12/synset_words.txt
There is a way to do object detection, retraining Inception model provided by Google in Tensorflow? The goal is to predict wheter an image contains a defined category of objects (e.g. balls) or not. I can think about it as a one-class classification or multi-class with only two categories (ball and not-ball images). However, in the latter I think that it's very difficult to create a good training set (how many and which kind of not-ball images I need?).
Yes, there is a way to tell if something is a ball. However, it is better to use Google's Tensorflow Object Detection API for Tensorflow. Instead of saying "ball/no ball," it will tell you it thinks something is a ball with XX% accuracy.
To answer your other questions: with object detection, you don't need non-ball images for training. You should gather about 400-500 ball images (more is almost always better), split them into a training and an eval group, and label them with this. Then you should convert your labels and images into a .record file according to this. After that, you should set up Tensorflow and train.
This entire process is not easy. It took me a good couple of weeks with an iOS background to successfully train a single object detector. But it is worth it in the end, because now I can rapidly switch out images to train a different object detector whenever an app needs it.
Bonus: use this to convert your new TF model into a .mlmodel usable by iOS/Android.
