If you’re venturing into the exciting world of intent discovery using deep learning techniques, you’ve landed at the right place! We will explore the deep aligned clustering method, which allows you to discover new intents effectively. Buckle up as we guide you through a step-by-step journey that will help you set up and run this method with ease!
Introduction
The essence of this approach lies in its integration with the open intent discovery module. You can find the implementation on the official GitHub repository for [open intent discovery](https://github.com/thuiar/TEXTOIR/tree/main/open_intent_discovery). Additionally, you can explore the scalable framework [TEXTOIR](https://github.com/thuiar/TEXTOIR). Let’s dive deeper!
Dependencies
Before we dive into using the model, we need to set up our environment. Here are the steps to get everything ready:
- Create a Python environment using Anaconda:
conda create --name your_env_name python=3.6
pip install -r requirements.txt
Model Preparation
Next, let’s prepare our model:
- Download the pre-trained BERT model.
- Convert it into Pytorch format.
- Set the path of the uncased BERT model in
init_parameter.py
.
Usage
Now that your environment is set up, you can run the experiments:
- Execute the following command:
sh scripts/run.sh
dataset
: clinc, bankingfactor_of_clusters
: 1 (default), 2, 3, 4known_class_ratio
: 0.25, 0.5, 0.75 (default)
Understanding the Code Through an Analogy
Imagine trying to sort different types of fruits into several baskets based on their characteristics: color, size, and taste. Each basket represents a cluster of similar fruits. You start by sorting them based on color, but as you delve deeper, you realize that size also plays a crucial role. Just like in this process of clustering, the deep aligned clustering method evaluates multiple traits to segregate data into more meaningful clusters, finding deeper insights into intents that define natural language processing.

Troubleshooting
While everything should go smoothly, here are some troubleshooting ideas if you encounter hiccups:
- Environment Issues: Ensure your anaconda environment is activated.
- Model Loading: Verify the path to the BERT model is correct in
init_parameter.py
. - Script Errors: Double-check the syntax in your shell script; minor typos can cause major roadblocks.
