Artificial Intelligence (AI) is quickly changing the financial services industry. Financial institutions are using AI to improve efficiency, enhance the customer experience, and to be able to compete in the market.
AI Use Case Examples in Financial Services
- Determine good or bad credit
- Detect and prevent fraud
- Customize financial products
- Simulate real-world scenarios
- Personalize customer interactions
- Optimize trading strategies
Capital One Financial, for example, has publicized how they are applying AI and machine learning to improve their fraud detection systems. This has reduced false positives, improved detection rates, lowered costs, and increased customer satisfaction.
However, up to 80% of AI/ML project timelines are spent on data preparation.
Data is a Critical Success Factor to Ensure Accuracy in AI

The accuracy and effectiveness of any AI-driven application is directly dependent on the accuracy and completeness of the data used to train, validate, and test its machine learning algorithms. So much so, that training data has been called the programming language for AI.
The challenge for AI developers is to access, collect, evaluate, and prepare training data that meets this very demanding quality standard. They must ensure the datasets provisioned for training their models mitigate the following risk factors.
- Data Privacy & Security: Deploying AI in the highly regulated financial sector requires strict alignment with regulatory frameworks like General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), as well as implementing robust governance structures and security measures to protect customer data and maintain trust.
- Algorithmic Bias: When AI systems are trained on existing financial data, especially small data samples, they risk perpetuating existing biases and discriminatory patterns, leading to unfair outcomes for certain customer segments. Financial institutions must proactively identify and mitigate algorithmic bias to ensure equitable treatment and avoid reputational and legal risks.
- Data Accuracy & Completeness: Incorrect and missing data values can lead to incorrectly trained AI algorithms which increases the probability of false positives, flawed predictions, and incorrect risk assessments. And complex training data must also maintain accurate data relationships, so called “referential integrity,” to ensure that the training data is accurate and useful.
- Sufficient Volume: It’s well understood that AI benefits from large volumes of training data. And not just “positive” data for machine learning; the signal for what “fraud” looks like must be able to be amplified to give the AI algorithms sufficient data examples to learn from and minimize false positives.
- Evidence for Audits: Financial institutions must strive to develop more interpretable AI models and provide clear explanations for AI-driven decisions to stakeholders, regulators, and customers. This requires traceability as to how the data was designed.
AI Training Data Solutions
Here are four alternative solutions for machine learning training data:
- Copy and “mask” production data
- Use Generative AI (Gen AI) tools to generate data
- Use synthetic data generation tools to replicate production data
- Use GenRocket to design and generate any volume & variety of synthetic data
Option 1: Copy and Mask Production Data
Copying and masking production data is often the first consideration for training data. However, it has at least three drawbacks.
* Achieves functionality
** Doesn’t achieve functionality
- Data Security* – Data is secure. However, depending on the security posture, masking algorithms can potentially be reverse-engineered, and still compromise sensitive information.
- Data Bias** – Production data often contains inherent biases that can skew AI model training.
- Data Accuracy & Completeness** – Gaps in production data can lead to incomplete training datasets.
- Sufficient Volume** – Limited production data may not provide enough volume for comprehensive AI training.
- Evidence for Audits* – Masked production data can be used as evidence during audits.
Masked production data may not adequately address data privacy concerns. Masking uses an algorithm which can be reverse-engineered so even after masking sensitive information, there is still a risk of data leakage or re-identification. This can lead to compliance issues and damage customer trust.
Moreover, production data often lacks the variety needed for comprehensive AI training and testing. It may contain biases and fail to represent certain scenarios adequately. Additionally,
production data frequently suffers from various data quality issues such as missing, inconsistent, or inaccurate values.
Option 2: Use Gen AI to Generate Synthetic Data
Using Gen AI is being considered for machine learning training data, however, it has at least three drawbacks.
* Achieves functionality
** Doesn’t achieve functionality
- Data Security* – Synthetic data generated by GenAI tools maintains data privacy and security.
- Data Bias** – GenAI-generated data may inherit biases present in the source production data.
- Data Accuracy & Completeness** – GenAI tools can produce inaccurate data points (“hallucinations”) and may not ensure referential integrity.
- Sufficient Volume* – GenAI tools can generate large volumes of synthetic data for AI training.
- Evidence for Audits** – GenAI-generated data cannot be reliably reproduced for audit purposes.
Some developers have turned to GenAI tools to generate synthetic training data as a way to mitigate the risks associated with using production data. While these tools can create new
datasets by imitating real-world patterns, they may not always be suitable for training algorithms in the financial services industry.
One major concern is the accuracy and reliability of the generated data. GenAI models are susceptible to hallucinations, producing plausible but incorrect data points. In the financial
services context, such inaccuracies can lead to serious consequences, like flawed risk assessments or undetected fraudulent transactions.
Furthermore, GenAI models can generate biased or inconsistent data, especially if the training data itself is biased or fails to fully represent critical scenarios. This can result in AI models
learning and amplifying these biases, leading to inaccurate or unfair predictions.
Another challenge is maintaining referential integrity between key data elements, which is essential for data accuracy in real-world scenarios where data comes from multiple sources.
GenAI tools do not guarantee this referential integrity in the data they generate.
Option 3: Use Synthetic Data Generation Tools to Replicate Production Data
A number of synthetic data generation tools vendors have entered the market. These tools typically work by profiling a production dataset and generating a statistically accurate replica of the data, however, they have at least three drawbacks.
* Achieves functionality
** Doesn’t achieve functionality
- Data Security* – Synthetic data generation tools create secure, privacy-compliant datasets.
- Data Bias** – Replicating production data perpetuates existing biases in the synthetic dataset.
- Data Accuracy & Completeness** – Synthetic data replication may not address gaps or inconsistencies in the source data.
- Sufficient Volume** – Synthetic data replication may not provide sufficient volume for comprehensive AI training.
- Evidence for Audits* – Replicated synthetic data can serve as evidence during audits.
While replicating production data with synthetic data generation tools may seem like a viable approach, it has a significant drawback. These tools reproduce not only the data but also all the quality issues present in the original dataset, including inconsistencies, gaps and biases.
In the financial services industry, these limitations can have serious implications. If the production data contains inconsistencies and biases, the synthetic data will inherit them. Training an ML model with invalid data can undermine its accuracy and produce costly false positives or negatives. So while this approach reduces security risks, it presents the same data quality challenges as using masked production data.
Synthetic data generated by these tools also often lacks completeness, as it relies on the quality of the source production data. These tools typically lack the ability to design new data that does not exist in production such as data that amplifies the signal of what fraud data looks like. While these tools help address data privacy concerns, they aren’t the best solution for machine learning training data.
