An Interface for Active Learning
Interface for Active Learning
About Active Learning
Active learning is the process by which a learning algorithm can query a user interactively to label data points which are close to the decision boundary formed during classification
The primary objective of this project is to build an Interface for Active learning which simplifies the process of chosing algorithms,query strategies and labels This eliminates the task of writing programs for each task The interface helps annotators of various domains to label data in an interactive manner and also provides features of saving the final model and results
Interface for Active Learning supports Image dataset where the user can upload data in Zip format. It supports 3 classifiers and 7 query strategies.
Random Forest Classifier
Decision Tree Classifier
Query By Committee(Uncertainty Sampling)
Query By Committee(Vote Entropy Sampling)
Query By Committee(Max Disagreement Sampling)
Query By Committee(Consensus Entropy Sampling)
This project is implemented with the Active Learning package modAL
How to Run
This project requires python 3.x installed on your machine
InstallationThe package can be installed using the command : pip install activizer
Open Python console and run the following commands
from activizer import app
Copy the url in the browser
Select the Classifier Algorithm, the Query Strategy and give the number of samples you wish to label. Then select the training / testing dataset in Zip format
- For each iteration an image will be shown and a dropdown to label that image. Below them will be shown a graph with current accuracy.
- After all the iterations are over, Final accuracy with graph will be shown
The user can see the images along with the labels provided by the algorithm selected during training. The trained model can be downloaded in pickle format (.pickle file) and can be used for prediction by clicking "Already have a model" on the Main Page. The user can then upload the pickle file and use the model to classify images
The Interface can be used for prediction by uploading the validation dataset in Zip format.
- The result will be shown in a table consisting of image name and label predicted by the model.
