QUESTION
I am working on Kaggle competition and trying to solve a multilabel classification problem with keras.
My dataset is highly imbalanced. I am familiar with this concept and did it for simple machine learning datasets, but now sure how to deal with both images and csv data.
There are a couple of questions, but they did not help me.
...ANSWER
Answered 2021-Feb-28 at 12:11I'm not sure if this answer satisfies you or not, but here is my thought. If I were you, I wouldn't try to balance it in the way you're trying it now. IMO, that's not the proper way. Your main concern is this VinBigData is highly imbalanced and you're not sure how to address it properly.
Here are some first approaches all would adopt to address this issue in this competition.
QUESTION
I am working on a d3 application - which features a bar chart with nodules on the top. I am keen to get this animated - so the bars grow to the point of rest and the nodules sprout like flowers.
So the nodules are either developed at the start and the bars just rise -- or the bars rise up and then the nodules flower.
//old js fiddle http://jsfiddle.net/s1f4hzpu/1/
//current animation attempts http://jsfiddle.net/9yvn8c4q/
...ANSWER
Answered 2020-Nov-18 at 23:03Firstly, you don't need jQuery, you can do everything you want with regular d3.
Regardless, if you want to make the bars grow, you need to know that y=0
is the top and y=height
is the bottom, so you need to actually decrease y
as you increase height
.
I also wouldn't draw a circle in front of another circle, but would use stroke
and fill
colours instead. If you make a stroke of 5 pixels wide, then it looks the same as in your example.

I am using oidc-client.js
in my angular
project.
Right now users could log-in and log out and it works fine. the only problem is that when I want to call a service in app.component, in the interceptor the user is not authenticated.
auth.service is :

Answered 2020-Oct-29 at 12:40Try to make your call inside and ngAfterViewCheck
instead of ngOnInit
because services at this moment aren't initiated yet. Be careful that would be executed infinitely. You can keep make the call, while the user is undefined.

QUESTION
I have created a 3d numpy array of data (shape: 133 x 512 x 512) from dicom format. Given a center point of a nodule location, how would i extract a 3d volume of size 40mm x 40mm x 40mm. I am not sure how would the pixel to mm conversion happens? I have attached the data here. The location of nodule is (317, 363, 89) which is (x,y,z) where z denotes the number of slice. So for this example, the nodule is on slice 89. Here is the sample data. It is in nrrd format. In the dicom header information, the slice thickness was given 2.5 and pixel spacing as ['0.703125', '0.703125'].
...ANSWER
Answered 2020-Jul-06 at 06:14It looks like the NumPy array coordinates are reversed to (z, y, x) aka (plane, row, column), see this scikit-image documentation for more details on this. Additionally, let's take the voxel spacing to be equal to [2.5, 0.703125, 0.703125], though I couldn't find this information with pynrrd. But, visualising it, I these measurements looked right. The units of this are mm/pixel.
Now, you want to convert 40mm, or rather half that, 20mm, to pixels. You do this by dividing by the mm/pixel, so you get a box size of:
QUESTION
It must be something pretty obvious, but for some reason, I am missing it after a couple of hours looking at it very closely..
I am building a multi-module Spring Boot project following hexagonal architecture with Gradle 5.1.1, so I have several adapters like this rest-adapter
for which the gradle.build
file is below :
ANSWER
Answered 2020-Apr-07 at 08:16I am a newbie to Gradle. So maybe there is a better way to do this, but I will try to answer
I think the issue is for the sub-project's transitive dependency to be accessed by another sub-project we need to make it api
rather than implementation
.
In rest-adapter for its internal dependency to be available in acceptance-test like in this case
implementation 'org.springframework.boot:spring-boot-starter-web'
change it to api
i.e.
api 'org.springframework.boot:spring-boot-starter-web'

QUESTION
I have attempted training a model for binary classification problem using a dataset made of medical pictures(LIDC dataset to be exact), which, too my understanding, shouldnt be too far from the "dog vs cat" classification problem. ( distinguishing between benign and malignant nodules )
Problem is, the accuracy seems to stucks, from the beginning to about 65% and doesnt seem to change at all. Am i doing something wrong ? The example that was provided by my friend easily reaches more than 80% and the accuracy is improving epoch after epoch, but not mine :/
I am training on already extracted patches, all of the same size and separated into two classes.
The model i am using a VGG16 fine-tuned for this task ( i replaced the FC layers with new ones, freezed the previous layer and attempted training )
I have tried changing to binary_crossentropy, applying to_categorical, change the last layer from 1 to 2. At his point, i am confused on the correct combination of parameters for my problems. Sorry if i sound like an absolute beginner...
i tried skipping the less informative parts of the code, hope its readable
...ANSWER
Answered 2019-Oct-15 at 10:27Since you have a single-unit output layer and binary cross-entropy loss, you should use a sigmoid
activation for your last layer; change it to:
