With the explanation, grad-cam, we can observe which regions the classification model focuses on to make a prediction. We can debug the model based on the explanation.", "is there also a possibility that insufficient data is fed to the training data leading to a false prediction ? as some objects might be unique in different ways", "Yes, exactly. insufficient data can lead to false predictions. For example, if there is not enough data, a classification model may use the appearance of water to predict the goldfish.", "In what kind of contexts are we planning to use these models for? Research, school, identifying features in an environment, etc?", "The classification models are fundamental models for many other tasks, like face recognition or self-driving. For the explanation method, it can be used in many sensitive areas, like healthcare, finance, and legal systems. We can use the explanation method to understand the reasons behind a machine learning model's prediction.", "the model used here is to identify the object, but can it identify the number of objects?", "It can do that. But here, it was trained to recognize the main object in the image.", "if the fish in the image is very small compared to the one here, can it still predict accurately? Does the size matter?", "I'm not sure about this. It will depend on the data used to train the classification model. But usually, size matters. As a larger size of the objects may contain more features that can be detected by models.", "I have no more questions", "Okay. Thanks for your questions!" ] }

It is used to explain the prediction from the classification model. There is a classification model that can classify an image into a category. Here it classifies the image as a goldfish. But the classification model is complex. We don't understand it. We don't know how it predicts the image as a goldfish. Then we use the grad-cam, an explanation model to generate the second image, which tries to explain which region the classification model focuses on to make such a decision.", "Interesting. In the event that there is more than 1 important region in an image (e.g. the image has a goldfish and a shark), will the grad-cam be able to detect both creatures?", "Grad-cam actually cannot detect features. It is used to explain the prediction of the classification model, which is swin transformer here. But if you mean whether the swin transformer can detect both creatures, it may do it. A good classification model should assign high probability to both shark and goldfish if an image contains both of them.", "Sorry, I meant the heatmap since the resulting heatmap will overlay on the original image to provide a visual representation", "If we use the grad-cam to explain how the classification model classifies the image into the shark class, a good classification model will focus on the features related to the shark. it's the same for the goldfish.", "What does it mean by \"weighting the activations of the final convolutional layer by their corresponding gradients\"? Does that refer to the colour gradient of the image?", "The classification model will first extract features from original images, and generate a feature map. Then we will calculate how changes to each feature would affect the network's output. The feature map here is \"activations of the final convolutional layer\". if the prediction is sensitive to some features in the feature map, this means those parts of the feature are of high importance, and it will be redder in the heatmap.", "I understand. Does the grad-cam method have a high probability of correct predictions?", "We cannot measure its correctness as there is no ground truth for the explanation of the classification model. But it works pretty well in general. The classification model, swin transformer, predicts quite accurately. Around 84% on a very large dataset (i.e., imagenet.)", "Thanks for the explanations. I have no more questions.", "Thanks for your questions." ] }
