kandi X-RAY | Flair Summary
This is an android framework for build complex application with different architectures (MVC ready/MVP/MVVM/MVI ets). It's create on top of MVC pattern with powerful event system, constructor injection module and property delegation, also it support multi-core instances and animation changes between views (see example project for more information). The FlairFramework is easy to use, it's light-weight, extensible, flexible and it's has more simplier view lifecycle than Fragments and Activities. The start point for initialize framework is declare 'flair' instance in onCreate method in MainApplication file. But u can initialize framework in any part of your project such as MainActivity or any Context implementations. The second point or using 'Flair' is attach created core to single Activity class and root layout container (but u can no specify any root container and 'Flair' take it for you automatically as activity.window.decorView.findViewById(android.R.id.content)). Important thing: only one activity can be stored in one core of FlairFramework. Mediators can handle notification by. Proxy object can recieve notification by linked commands as usecases. Register all components of Flair framework (Mediators, Proxies, Command) in any part of your application by calling lazy functions or inline functions like proxy(), proxyLazy(), mediator(), mediatorLazy() from reflection module since 1.5.+. You can use powerful feature from kotlin lang like lazy val instantiating, this is an example with custom constructor parameters. Important note: that since version 1.5.+ you need to add. Since verson 1.1.3 added new extension functions. Since version 1.1.4 you can use FlairPagerAdapter for control viewPager with mediators.

QUESTION
As mentioned in this other question, I'm setting my first steps in C# and JSON.
I'm working on a small application, that can read information from a DB and write it in a JSON file. In order to do this, I thought of creating the classes as they were defined in the JSON file. For that, I used Web Essentials and this has done a great job: the classes are generated completely. All this is mentioned in my previous question.
Now I was thinking of using those classes to write back to the JSON file, so I have this situation:
...ANSWER
Answered 2021-Jun-10 at 11:31Apparently (as mentioned by Ruan), Web Essentials can turn a JSON file into a class model, but in the other direction, another way must be followed.
The way, which is mentioned (NewtonSoft), is a very good one:
- Add "NewtonSoft" as a reference (I did it, using the NuGet package Manager).
- At the beginning of the source code, add
using Newtonsoft.Json;
. - The conversion to JSON is simple:
string result = JsonConvert.SerializeObject(root);
.

I created a text classifier that uses Tf-Idf using sklearn, and I want to use BERT and Elmo embedding instead of Tf-Idf.
How would one do that ?
I'm getting Bert embedding using the code below:
...ANSWER
Answered 2021-Apr-15 at 15:54Sklearn offers the possibility to make custom data transformer (unrelated to the machine learning model "transformers").
I implemented a custom sklearn data transformer that uses the flair
library that you use. Please note that I used TransformerDocumentEmbeddings
instead of TransformerWordEmbeddings
. And one that works with the transformers
library.
I'm adding a SO question that discuss which transformer layer is interesting to use here.
I'm not familiar with Elmo, though I found this that uses tensorflow. You may be able to modify the code I shared to make Elmo work.

QUESTION
I am quite new to the field of semantic segmentation and have recently tried to run the code provided on this paper: Transfer Learning for Brain Tumor Segmentation that was made available on GitHub. It is a semantic segmentation task that uses the BraTS2020 dataset, comprising of 4 modalities, T1, T1ce, T2 and FLAIR. The author utilised a transfer learning approach using Resnet34 weights.
Due to hardware constraints, I had to half the batch size from 24 to 12. However, after training the model, I noticed a significant drop in performance, with the Dice Score (higher is better) of the 3 classes being only around 5-19-11 as opposed to the reported result of 78-87-82 in the paper. The training and validation accuracies however, seem to be performing normally, just that the model does not perform well on test data, I selected the model that was produced before overfitting (validation loss starts increasing but training loss still decreasing) but yielded equally bad results.
So far I have tried:
- Decreasing the learning rate from 1e-3 to 1e-4, yielded similar results
- Increased the number of batches fed to the model per training epoch to 200 batches per epoch, to match the number of iterations ran in the paper since I effectively halved the batch size - (100 batches per epoch, batch size of 24)
I noticed that image augmentations were applied to the training and validation dataset to increase the robustness of the model training. Do these augmentations need to be performed on the test set in order to make predictions? There are no resizing transforms, transforms that are present are Gaussian Blur and Noise, change in brightness intensity, rotations, elastic deformation, and mirroring, all implemented using the example here.
I'd greatly appreciate help on these questions:
By doubling the number of batches per epoch, it effectively matches the number of iterations performed as in the original paper since the batch size is halved. Is this the correct approach?
Does the test set data need to be augmented similarly to the training data in order to perform predictions? (Note: no resizing transformations were performed)
ANSWER
Answered 2021-Mar-18 at 21:48- Technically, for a smaller batch the number of iterations should be higher for convergence. So, your approach is going to help, but it probably won't give the same performance boost as doubling the batch size.
- Usually, we don't use augmentation on test data. But if the transformation applied on training and validation is not applied to the test data, the test performance will be poor, no doubt. You can try test time augmentation though, even though it's not very common for segmentation tasks https://github.com/qubvel/ttach

I am trying to implement the 'Bottom-Up Computation' algorithm in data mining (https://www.aaai.org/Papers/FLAIRS/2003/Flairs03-050.pdf).
I need to use the 'pandas' library to create a dataframe and provide it to a recursive function, which should also return a dataframe as output. I am only able to return the final column as output, because I am unable to figure out how to dynamically build a data frame.
Here is the python program:

Answered 2021-Mar-14 at 09:46Unfortunately pandas
doesn't have functionality to do subtotals - so the trick is to just calculate them on the side and concatenate together with original dataframe.
