The AI-driven world we’ve been promised for years has arrived. Data-driven businesses are all turning to Artificial Intelligence to improve output. In fact, 45% of them say they’ve already integrated AI as part of their operations. Humans are ready for AI. But is AI ready for us? One of the biggest data training challenges that AI faces at the moment lies around data quality.
AI needs to process massive amounts of data to become useful, and that data needs to be accurate. Annotation errors could have tremendous consequences in the real world. So how can we improve data accuracy? First, we need to understand where the problem comes from.
Preparing data at scale
An effective AI system starts with high-quality training data produced at scale. But what exactly constitutes high-quality training data?
- Accurate. The data is free from errors, inconsistencies, and bias.
- Complete. It contains all necessary information without significant missing values.
- Consistent. The data is annotated following clear and detailed annotation guidelines.
- Proper domain and user coverage. It’s relevant to the specific domain or industry it’s intended for.
- Timely. Data is up-to-date.
- Balanced. All cases must be included in representative proportions.
The challenge is that the more data a business needs to produce, the harder it is to keep it accurate and consistent.
The best way to produce high-quality data to train AI systems is through skilled, manual human annotation. This process enables machine learning algorithms to learn much faster and with more precision. However, realiable, accurate models demand vast datasets of annotated data. (And this grows exponentially with generative AI and Large Language Models).
This often leads to a resource imbalance, with companies dedicating a disproportionate amount of time and resources (up to 80% of AI project time) to data preparation rather than model development.
Being able to scale the data annotation process effectively requires a sophisticated approach that integrates human expertise with advanced technologies, and well-designed processes.
The need for a highly-skilled human workforce
When we are teaching AI what a cat looks like, the skill needed to annotate the data annotation process is relatively easy. But as AI applications become more sophisticated and domain-specific, the skills required for human data annotation become more challenging.
Take the example of an AI systems designed to analyze X-ray images in healthcare. Annotating medical images requires expertise, as human annotators must have medical training to accurately identify and label anomalies in X-ray scans. This translates to increased costs for the company, either through extensive training programs for existing staff or by hiring qualified medical professionals. And of course, as the data becomes more specialized and complex, the level of human expertise required escalates.
Not everyone can become a highly killed human annotator. Some of the basic skills required involve attention to detail, patience, dexterity, language expertise, and the ability to understand detailed annotations guidelines and apply them consistently. On top of this, generative AI brings an entire new skillset, which involve:
- Logical and linguistic reasoning
- Creative thinking
- Summarization
- Prompt writing
- Paraphrasing
- Attention to detail
- Research skills
Gen AI annotation tasks are far more subjective, and require a nuanced understanding of human language, and excercise human judgement in the data annotation process, to guide the training of AI models that can emulate human-like reasoning and creativity.
For companies, this means upskilling your human annotation teams. This can involve providing training programs on the specific skills demanded by gen AI, but also developing assessments that allow you to identify the best candidates for each project.
Complying with security and privacy standards
Data quality is essential, but not the sole factor in buiding a strong and clean training dataset. Ethical considerations and robust security measures are equally important.
A clean training dataset must prioritize the protection of personally identifiable information (PII) and minimize its use whenever possible. While some applications, such as facial or speech recognition, inherently require the use of sensitive data like images and voice recordings, it’s imperative to handle this information responsibly.
The misuse of personal data could infringe on people’s freedom and pose significant safety risks. The lack of consistent data protection regulations across all countries presents a significant challenge. This requires a proactive approach from AI companies, emphasizing self-regulation and prioritizing individual privacy.
But how can we ensure consistent ethical practices across the industry?
Aligning with established privacy and security standards, such as GDPR, CCPA, CPRA, SOC 2, and DPA, provides a strong framework for building trust and ensuring ethical data handling practices. This approach creates a level playing field and promotes responsible AI development across the global landscape.
