Data-Centric AI Development: How Generative AI Can Enhance Data Quality and Diversity?

Artificial Intelligence is dependent on data. AI models can learn appropriately and give accurate predictions only with rich and appropriate data. The last few years have also seen an increasing focus on data-centric AI, the approach in which data looks and performs better concerning AI performance. 

Conventional data collecting and preparation techniques typically need to supply enough data for better data-centric AI models. However, current generative AI, a kind of AI that concentrates on producing new data, could help with these issues.

The Limitations of Traditional Data Collection and Preparation Methods

Traditional methods of data collection and preparation often face several limitations:

• Lack of Data: A 2023 Gartner report found that up to 80% of businesses need more data for AI model training in specialized areas like rare diseases, niche markets, and unique geographies. Several territories, especially unique ones, need more data to build AI models.
  
• Data Discrimination: Generative AI can alleviate the effect of data discrimination by ensuring that AI models can predict results reasonably and unbiasedly. As reported by the OECD, approximately 43% of AI models in consumer finance and healthcare were found to have been unintentionally biased.
  
• Data Disturbance: Impure data may prevent AI models from performing at their best. Noisy or inconsistent data can degrade model performance. According to IBM, data scientists spend 80% of their time cleaning and preparing data, a time-consuming process that generative AI can help streamline.
  
• Costs of Data Annotation: While it could be easy to collect large amounts of data, annotating it can be costly and labor-intensive. Manual data annotation is expensive, with a single data labeling project costing over $100,000 on average. Generative AI can help generate synthetic data with predefined labels, significantly cutting costs.

Generative AI can help address these consequences by:

• Data Augmentation: Generating synthetic data to increase the size and diversity of datasets. DataRobot estimates that augmenting data can improve AI model accuracy by up to 15%.
  
• Data Cleaning and Noise Reduction: Identifying and removing noise and inconsistencies in data.  Generative AI models can reduce data noise, with a 2023 McKinsey survey showing a 20% performance improvement in AI models trained on denoised data.
  
• Data Balancing: Addressing class imbalance issues, which occur when one class in a dataset is much more frequent than the others, by generating synthetic samples of underrepresented classes. A KPMG report highlighted that 75% of organizations experienced up to a 30% increase in accuracy when using balanced datasets.
  
• Data Privacy: Safeguarding confidential information by creating synthetic data that captures the original data’s statistical features. A 2022 Future of Privacy Forum survey showed that 60% of companies consider synthetic data essential for privacy compliance without sacrificing data utility.

Understanding Data Quality and Diversity: The Foundation of Data-Centric AI

Data Quality

Any AI model must succeed in high-quality data, which refers to the degree of accuracy, completeness, consistency, timeliness, and relevance of the data.

• Precision: Information must be exact and free from errors. Incorrect information leads to misleading algorithms that can result in wrong forecasts. The 2024 AI Industry Report found that models trained on accurate data achieved 27% better performance.
  
• Sufficient: The information should be complete with no blank cells. If the information is adequate, the training might improve the developed model.  A study by Accenture estimated that 45% of failed AI projects needed more data.
  
• Consistency: The data could be uniform in terms of type and origin. Any inconsistency in the information means misunderstanding and sometimes error.
  
• Currency: The information has to be time-bound and relevant to the existing scenario. This may lead to false predictions when using antiquated information.
  
• Applicability: All information must relate to the subject or activity being discussed. Too much information can choke the signal, causing the model’s performance to suffer.

Data Diversity

Data diversity in datasets means the collection of various data points or examples. Many studies have explained that encouraging diversity in datasets helps explain AI models centered on data.

• Demographic Diversity: Data should include people of all ages, genders, races, and ethnicities. This can help reduce bias in AI structure thanks to its diversity. Google’s AI report in 2023 found that models with demographic diversity improved fairness by 20%.
  
• Geographical Variation: Site selection should focus on sampling in different regions and cultures to enhance understanding of regional differences. A PwC study found that global models had a 25% higher success rate in international deployments.
  
• Language Diversification: The corpus of data must integrate text and speech data from different languages. This will help improve the language capabilities of AI models.
  
• Content Diversity: The data should span many subjects and fields. Consequently, the application of data-centric AI models could become more general.

The Importance of Data Quality and Diversity for Data-Centric AI

It requires a good and rich variety with diverse datasets for sound and information-rich data-centric AI systems. Further, crisp and well-formatted complete data enhance the system’s robustness and prevent the misuse of bias.

Data quality tools and diversity represent the focal points of a data-centric AI paradigm, as the improvement of model performance is centered on the quality and quantity of data.

Good data and CoMM, which stands for content management and metric activity, are critical components of any data-centric AI development. 

If building capable and accurate artificial intelligence systems is a course put in place, the second and foremost is the availability of sufficient data-centric AI models explaining the use and interaction of various algorithms with relevant data analytics.

Strategies and Methods for Maintaining the Quality and Heterogeneity of the Data

• Data Cleansing: The detection and rectification of anomalies, discrepancies, and absent values in the data. According to Deloitte, companies reduced data errors by 30% using AI-driven data cleansing tools.
  
• Data Verification: Ensuring the information collected is accurate and exhaustive.
  
• Data Generation: An imposed expansion of the scope of creating data. Gartner projects that AI-driven annotation can lower costs by 60% by 2026.
  
• Data Annotation: Apply the correct approach to tag data for training use.
  
• Data discrimination and imbalance Reversal policies. The acknowledgment and rectification of present biases in the data subjects.

In this way, organizations can fully utilize AI’s potential and encourage creativity in their field by emphasizing the quality and variety of data.

Generative AI Techniques for Data Enhancement

Data Augmentation

It refers to adding more information to a dataset through methods for replication or the generation of fake data. This effect can significantly influence the effectiveness of machine learning models, especially when the latter are trained on tiny datasets.

Text Augmentation: OpenAI studies show that text augmentation can improve language model performance by up to 30% on limited datasets.

• Synonym Replacement: Creating new sentences by substituting words with their synonyms.
• Back-translation is the process of translating text from one language to another and then back again.
• Text generation produces new text comparable to the original data using generative models such as GPT-3. 

Image Augmentation: Techniques like rotation and color jittering are instrumental in fields like facial recognition and medical imaging, where Stanford research has shown a 15% accuracy boost in augmented datasets.

• Rotation: The act of turning the image in different degrees of angles. 
• Images can also be turned upside down or horizontal flips done on them. 
• Cropping refers to the reduction and altering of size and shape in an image.
• Color jittering is an image’s ‘intentional color, intensity, temperature, and light level alteration.’
