Deep learning model test accuracy unstable

Asked 2021-Apr-22 at 09:30

I am trying to train and test a pytorch GCN model that is supposed to identify person. But the test accuracy is quite jumpy like it gives 49% at 23 epoch then goes below near 45% at 41 epoch. So it's not increasing all the time though loss seems to decrease at every epoch.

My question is not about implementation errors rather I want to know why this happens. I don't think there is something wrong in my coding as I saw SOTA architecture has this type of behavior as well. The author just picked the best result and published saying that their models gives that result.

Is it normal for the accuracy to be jumpy (up-down) and am I just to take the best ever weights that produce that?

Accuracy is naturally more "jumpy", as you put it. In terms of accuracy, you have a discrete outcome for each sample - you either get it right or wrong. This makes it so that the result fluctuate, especially if you have a relatively low number of samples (as you have a higher sampling variance).

On the other hand, the loss function should vary more smoothly. It is based on the probabilities for each class calculated at your softmax layer, which means that they vary continuously. With a small enough learning rate, the loss function should vary monotonically. Any bumps you see are due to the optimization algorithm taking discrete steps, with the assumption that the loss function is roughly linear in the vicinity of the current point.

You probably want to use a combination of JavaScript's requestAnimationFrame along with CSS's scroll-behavior:smooth;. Unfortunately scroll-behavior is pretty new, though.

SVG path animation jump

Asked 2021-Feb-11 at 22:39

I want to animate the SVG path. I have the same points with the same bezier settings. When I move 2 points to the rectangle center, the animation is jumpy and not smooth.

I found that if these points aren't initially at the straight path, so the animation is smooth! It looks like a bug(

Please take a look at the code below that demonstrates the issue or check it at jsfiddle

ANSWER

Answered 2021-Feb-11 at 22:39

I found that when dragging nodes in the vector editor, the type of nodes changes
Therefore, smooth animation is not obtained even if the number of node points is equal in the initial and final paths of the shape.

It remained to solve the problem of how to prevent the type node points from changing when dragging.
I found that most often the type of automatically smoothed points changes to other types of node points
Therefore, I tried to avoid using this type of node points.
I first created a rectangle with concave sides and then transformed these sides into straight lines.

With this technique, the type of node points did not change and the animation became smooth.

QUESTION

AWS Restrict Access But Allow Edit of a Security Group

Asked 2021-Feb-03 at 20:39

I work with a team of developers that has a shared database hosted in AWS. This team is "virtual" (comprised of remote workers--there is no officesi).

There is an AWS security group that has rules that allow each of the developers to access the database (by IP address). The senior developers have logins and admin permissions to AWS allowing them to change the security group rules--for example when someone's IP address changes.

The problem is that some of the junior developers have "jumpy" IP addresses which change frequently. Each time the IP address changes, a senior developer needs to stop work, login to AWS, and correct the security group rule for the junior developer. This is not sustainable.

Is there a way we can set up AWS so the junior developers can have logins to AWS, but their permissions only allow them to access a single, particular security group? That way the juniors can login to AWS and self-serve on the IP address update, and management doesn't need to worry that they have access to other, restricted areas in AWS?

To directly answer your question, there are multiple ways to achieve what you want and IAM and SCP are the things to take a look at.

With IAM you can either use IAM Permission boundaries to limit the privileges that a certain user has or rely on the ABAC approach where you assign a certain tag to the resource to which you want to grant access to. In your case you can have a "junior" tag set on the SG in question and a respective IAM policy that grants permissions based on it.

Another option is to use a Service Control Policy (in case you have AWS Organization enabled). With SCPs you can limit certain actions on account level (e.g. Deny action on ec2, unless a certain criteria is met). All of the above are on identity access level.

Networking-wise you can alter your design a bit by setting up an AWS Client VPN in front of the RDS.

if you give the .icon a background-color then you'll be able see the problem. its width changes while constantly trying to be centered as the text-align is set to center. that's why it jumped. i set its position to absolute so it doesn't move and change size. you can follow the css comments i have left in the code for more investigations. i also used the help of this Q&A, you can check that out either.

Loading Image from Core Data makes NavigationView transition jumpy

Asked 2020-Dec-08 at 11:25

In my SwiftUI app, when the user clicks an item in the List, it takes the user to the details view. In the details view, we need to display an image loaded from Core Data. The image data will be ready before the NavigationView transition finishes, but the NavigationView transition becomes jumpy when the image appears.

Here is the GIF image to see the jumpy transition: https://gph.is/g/aQqBqRA

Answered 2020-Dec-08 at 11:25

The .onAppear is called before animation start, so your loaded image causes view rebuild during animation, which result in observed effect.

If image cannot be loaded completely before animation, then it is better to postpone it until after animation completed, like

QUESTION

Choose to plot the line over the "edge" of the graph instead (and loop around), instead of across the graph

Asked 2020-Nov-12 at 01:32

So, I have a plot of the dihedral angle of a bond. The y-axis is only from 0-360, the x-axis is the frame (think timestep). I need the plot to "loop" back around to zero if the value goes above 360, and to plot the shortest distance between two points (if need be going over the edge of the graph and "looping" back around instead of across the graph).

The plot of d3 looks okay, but in reality needs to jump over the edge of the graph instead of across it.

the plot of d5 has a significant problem, for a small rotation there is a massive jump only because it happens to go just below zero degrees.

I would like for both these plots to plot towards the bottom (towards zero) and reappear at the top of the plot, effectively choosing the shortest distance between data points. I do not want solutions involving translation of the plots to remove these artefacts (it works, I've done it, but you loose information on the true value of the angle). Solutions that can plot "below zero" (so a y-axis from 300 to 360|0 to 200 to 300) are also great. Solutions using other libraries are perfectly fine. If needed I can provide the dataset.

Example of what I'd like it to do (green line)

I have tried to find similar solutions to no avail. The questions regarding periodic boundaries use numpy dataset mask to hide certain jumps, but they have continuous functions (where as mine are "jumpy").

Thank you for any help, I'd really appreciate it.

Using basic Python, as indicated by your lists, and not higher libraries like numpy, you can separate the two parts of the plot with basic functions. However, coming to think about your specific problem, you might prefer a polar plot:
