Improving Data Quality for Text Classification Tasks through Human-in-the-Loop Inspection of Synthetically Generated Data

Q: How can INSPECTOR be extended to support the inspection and curation of data for other types of machine learning tasks beyond text classification?

INSPECTOR can be extended to support the inspection and curation of data for various machine learning tasks by adapting its techniques to different data types and tasks. Here are some ways to extend INSPECTOR: Feature Engineering: For tasks like image classification or object detection, INSPECTOR can incorporate techniques to analyze image features or patterns. This could involve grouping images based on common transformations or visual features. Model-specific Metrics: Tailoring quality metrics and assistive labeling techniques to suit the specific requirements of different models and tasks. For example, for time series data, metrics related to trend analysis or seasonality could be included. Domain-specific Provenance Tracking: Customizing provenance tracking to capture domain-specific transformations or features. For example, in medical imaging tasks, tracking the processing steps applied to images could be crucial for quality assessment. Interactive Visualization: Enhancing the visualization capabilities of INSPECTOR to accommodate different data types. For instance, for graph data, providing interactive graph visualizations to explore relationships and patterns. Integration with Domain Knowledge: Incorporating domain-specific knowledge bases or ontologies to guide the inspection process. This could help users interpret the provenance information in the context of the specific domain. Collaborative Inspection: Facilitating collaboration among users with different expertise to inspect and curate data for diverse machine learning tasks. This could involve features for sharing insights, annotations, and decision-making processes. By adapting and customizing its techniques to different machine learning tasks, INSPECTOR can serve as a versatile tool for data inspection and curation across various domains and data types.

Q: How can the provenance tracking techniques in INSPECTOR be further improved to provide more meaningful and actionable insights for users, especially for complex data transformations?

To enhance the provenance tracking techniques in INSPECTOR for more meaningful insights, especially for complex data transformations, the following improvements can be considered: Fine-grained Tracking: Implement more detailed tracking of data transformations at a granular level. This could involve capturing intermediate steps in the transformation process to provide a comprehensive view of how the data has evolved. Interactive Exploration: Enable users to interactively explore the provenance information by drilling down into specific transformations or features. This could involve providing interactive visualizations or tools for detailed inspection. Pattern Recognition: Incorporate machine learning algorithms to automatically identify common patterns or anomalies in the data transformations. This could help users quickly identify recurring issues or trends in the data. Contextual Information: Provide contextual information along with provenance details to help users understand the implications of specific transformations. This could include explanations of why certain transformations were applied and their impact on the data. Feedback Mechanisms: Implement feedback mechanisms where users can provide input on the accuracy or relevance of the provenance information. This could help refine the tracking process over time based on user feedback. Integration with External Tools: Integrate with external tools or libraries that specialize in data lineage and provenance tracking to leverage advanced techniques and algorithms for analyzing complex data transformations. By incorporating these enhancements, INSPECTOR can offer users more comprehensive and actionable insights into the provenance of data, especially in the context of intricate and multifaceted data transformations.

Q: What are the potential limitations or biases that may arise from relying on a large language model's predictions for the assistive labeling feature in INSPECTOR?

When relying on a large language model's predictions for the assistive labeling feature in INSPECTOR, several limitations and biases may arise: Model Biases: Large language models are known to inherit biases present in the training data. This can lead to biased predictions, especially for sensitive or underrepresented groups, perpetuating existing biases in the data. Lack of Context: Language models may not always capture the context or nuances of the specific task or domain. This can result in inaccurate predictions, particularly for specialized or domain-specific data. Over-reliance on Model: Depending too heavily on the model's predictions without human validation can lead to blindly accepting incorrect labels, reducing the effectiveness of the inspection process. Adversarial Attacks: Large language models are susceptible to adversarial attacks, where subtle modifications to the input data can lead to incorrect predictions. This can be exploited to manipulate the labeling process. Uncertainty Estimation: Language models may struggle to provide accurate uncertainty estimates for their predictions. This can impact the reliability of the assistive labeling feature, especially in cases where confidence levels are crucial. Data Distribution Mismatch: If the data distribution used to train the language model differs significantly from the data being inspected, the predictions may not generalize well, leading to errors in labeling. Model Drift: Large language models are subject to concept drift over time, where their performance may degrade as the data distribution changes. This can affect the accuracy of the assistive labeling feature in the long term. To mitigate these limitations and biases, it is essential to combine the model predictions with human judgment, incorporate diverse perspectives in the labeling process, and continuously monitor and update the language model to improve its performance and mitigate biases.

Combining provenance tracking and assistive labeling techniques, INSPECTOR empowers users to efficiently identify and retain high-quality synthetic text data for improving the robustness of text classification models.

Sammendrag

The paper presents INSPECTOR, a human-in-the-loop approach for inspecting and curating synthetically generated text data for text classification tasks. INSPECTOR combines two key techniques to reduce human effort:

Provenance Tracking:
- INSPECTOR allows users to group the generated texts by their common transformation provenance (i.e., the transformations applied to the original text) or their feature provenance (i.e., the linguistic features of the original text).
- This enables users to efficiently inspect groups of related texts and identify patterns in data quality.
Assistive Labeling:
- INSPECTOR computes quality metrics such as label alignment, grammaticality, and fluency for each generated text and its corresponding label.
- It also provides the predictions of a large language model, which users can compare against the text labels to identify discrepancies.

The authors conducted a within-subject user study with 15 participants to evaluate INSPECTOR. The results show that using INSPECTOR, participants were able to identify 3-4 times more texts with correct labels compared to a baseline without the provenance tracking and assistive labeling features. Participants found the transformation provenance to be the most useful technique, as it allowed them to systematically inspect groups of texts and make informed decisions about their quality. The human-inspected data also improved the robustness of the text classification models by up to 32% compared to randomly sampled data.

The paper highlights that no single technique of INSPECTOR was found to be universally useful, suggesting that effective inspection of generated texts requires combining complementary techniques.

"Using INSPECTOR, participants identified an average of 277 and 259 high-quality instances compared to 82 and 63 instances using the baseline on the SST2 and TweetEval's Hate Speech dataset, respectively."
"On the SST2 dataset, 4 out of 8 participants marked data that led to more robust models than randomly sampled data. On the TweetEval dataset, all 7 participants identified data that led to more robust models than randomly sampled data."
"The attack success rate of DeepWord on models trained with randomly selected data was 0.61 on the SST2 dataset and 0.5 on the TweetEval dataset. Using the inspected data, the attack success rate decreases to an average of 0.59 and 0.34 on SST2 and TweetEval, respectively."
