QUESTION
I am trying to implement a binary classification with Neural Networks with Pytorch to train a model as shown below:
...ANSWER
Answered 2021-Apr-13 at 00:28I'll attempt to answer your questions:
Question 1 & 2:
Is it a right way to train a model? In many articles I found that there is a section to iterate over the DataLoader for training data.
You should use a dataset with a dataloader when training in pytorch for several reasons:
- It allows us to sample our data randomly
- It doesn't preload data into memory, which is particularly useful for huge datasets
- It operates in the background of code so fetches data parallel to training, thus saving time
- It's very efficient at batching your data
What you're doing here is seemingly running your model on every element in your data at once. If you only have 32 points in your data this might be fine (although really not optimal because you have such limited data) but there is a balance to strike between running your optimizer and exposing your model to learning opportunities.
I would guess this takes longer because your model is very small and it probably takes longer to run the data fetching than it does when it's already preloaded in memory. It is hard to answer this without knowing the size of your dataset and the batch size of your processing.
Question 3: Is it right way to test the model that I trained above?
You need to set your model to its evaluation stage using model.eval() before you run any inference code. I also don't understand the point of your for loop since you just pass through the same data every time. I would generally run something like this:
QUESTION
I've got some constants defined like this
...ANSWER
Answered 2020-Nov-28 at 09:37- Use Symbols instead of constants.
- Don't expose the mapping.
Constants in Ruby are mostly about information hiding. For example, if the key changes from consumer1 to consumer_1 as long as everything accesses the Hash with CONSUMER_1_TYPE you're ok. Why risk it?
Instead, fully hide the Hash. Now that it's hidden, constants are not necessary. Use Symbols.
If all the values are going to be the same, put them into their own methods.

QUESTION
I'm learning Python3 and I'm trying to create an object Agent (a custom object) by initiating the attributes of it from a JSON file.
The problem is that when I launch my python file, it does not find the file, which is in the same directory. I checked the name and the is no typo. I don't understand where the problem really is.
Here is my folder structure:
...ANSWER
Answered 2020-Mar-30 at 13:31Python opens the file relative to where the script is executed. So if you run the file with project/model.py the json should be outside of the project folder.
If the json is always included on the same folder that your python file you can use the follow code to open the file:
QUESTION
I'm sort of new to iOS development using Swift. So, I might be missing a simple solution in Swift that I'm not aware of. I am working on a tvOS app where I display a list of video content that the user can select from. The app also contains a settings tab that allows the user to configure 5 different types of settings. Once they select a specific category, it displays a new table view with the corresponding options which are in the options array. This is where the "issue" is that I need help.
I have this struct which I'm using as a singleton:

QUESTION
Here is my problem, I want to use one of the pretrain CNN network in a TimeDistributed layer. But I have some problem to implement it.
Here is my model:
...ANSWER
Answered 2017-Feb-21 at 04:26My quick solution is a little bit ugly.
I just copied the code of ResNet and added TimeDistributed to all layers and then loaded the weights from a "basic" ResNet on my customized ResNet.
Note:
To be able to analyze sequence of images like this does take a huge amount of memory on the gpu.
QUESTION
So I have 3 tabs in fruity.component.html, on my last tab I have a component
...ANSWER
Answered 2019-Dec-06 at 10:47I am unsure why you access your div through ViewChild and document query. I would advice you to stick with Angular tools rather than mixing up with raw JS queries.
The likely reason why you can't access style is because you are trying to access style of an object which does not reflect your div but something else. I could be more precise if you share your component.ts code, but I would think your ViewChild is typed as ElementRef. If so, you are one level of representation higher than the actual dom reference. You need to access nativeElement of your ElementRef and you should be able to retrieve its style.
If you retrieve a different type of ViewChild - such as any Material specified types - you will need to access first ElementRef from your component reference, then nativeElement and finally its style.

Answered 2019-Aug-27 at 11:53Your problem is that you modify (remove) a list while you iterate over it. Just put a few print lines into your code to see what it does.
It's better to create a new list and adding only characters that you want to keep:
QUESTION
I'm having trouble constructing a basic BNN in TFP. I'm new to TFP and BNNs in general, so I apologize if I've missed something simple.
I can train a basic NN in Tensorflow by doing the following:
...ANSWER
Answered 2019-Aug-15 at 14:01I expect it's because you're using TensorFlow 2, are you? It isn't fully supported yet. If so, downgrading to 1.14 should get it working.

No vulnerabilities reported
Install BNN
You can use BNN like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
