### Why do some of the algorithms take some extra space around the actual bounding box?

In some of the algorithms, there is a need to crop the object in an image. So, bounding boxes need to be used in order to crop the image to contain object only. Bounding boxes provide the information ...

### How to understand the common practices followed for writing a "bounding box" for an image in datasets?

For the image datasets, there may be a bounding box for each image at the dataset. It is an annotation for an image. It is a rectangular box intended for focusing on something inside the image. I read ...

### How to show $\rho > 0$ when $\rho$ be minimum attainable from $y_n(W^{*T}X_n)$, where $W^*$ the vector that separates the data?

In the book Learning from Data written (by Abu Mostafa), we have the following exercise: Let $\rho$ be minimum attainable from $y_n(W^{*T}X_n)$ where $W^*$ is the vector that separates the data. Show ...

### Do the output of RNN individual layers go through Softmax when going from one layer to the next in a stacked RNN (many to one architecture)?

In most of the online materials that I've read, the equations of RNNs are shown only for a single layer RNN with the output going through softmax (for a many-to-one architecture). I am trying to find ...

### In reinforcement learning, why are policies defined as functions of states and not observations?

I am new to RL and I am following Sutton & Barto's book. My doubt is, when we talk about the policy of our agent, we say it is the probability of taking some action $a$ given the state $s$. ...

### In anchor based object detection, why don't the anchors share the same weights?

After reading about YOLO V3 and Faster R-CNN, I don't understand why the weights for the regression head aren't the same across all boxes of the same size. Given that the backbone of these systems is ...
