Comparision Between Generative AI and Traditional AI/ML

Aspect Generative AI Traditional AI/ML Algorithms
Primary Function Generates new content (e.g., text, images, code) based on training data. Analyzes existing data to identify patterns, make predictions, or automate tasks.
Model Complexity Highly complex with numerous parameters, often using large-scale transformer-based models (e.g., GPT, LLaMA). Typically less complex, using simpler architectures like regression, decision trees, or standard neural networks.
Training Data Requires massive, diverse datasets (text, images, etc.) for training large language or multimodal models. Uses domain-specific datasets, which can be smaller and more focused.
Output Nature Produces creative or human-like outputs, such as conversational text or art. Produces structured outputs like classifications, predictions, or optimizations.
Data Use Capable of generating synthetic data for training or operational use. Primarily relies on real-world data for training and decision-making.
Explainability Higher risk of embedded biases due to diverse and often uncurated training data. Privacy concerns stem from the ability to infer personal information. Bias is present but easier to identify and mitigate. Privacy risks are lower as models are often domain-specific.
Bias and Privacy Capable of generating synthetic data for training or operational use. Primarily relies on real-world data for training and decision-making.
Robustness Susceptible to “hallucinations” or confidently incorrect outputs. Typically more robust and less prone to hallucinations but can struggle with unexpected data
Cybersecurity Poses risks like data poisoning, manipulation of training environments, and jailbreak attacks. Faces risks like adversarial attacks, but risks are generally less severe than GenAI.
Applications Natural language processing, creative content generation, conversational AI, fraud detection, and more. Predictive modeling, customer segmentation, anomaly detection, recommendation systems.
Adoption in Finance Useful for fraud detection, risk assessment, and customer service (e.g., chatbots). Used for credit scoring, financial forecasting, and fraud detection.

Key Features:

  1. Nature of Functionality: Generative AI creates new data or content, while traditional AI/ML focuses on deriving insights and making predictions based on existing data.
  2. Training Requirements: Generative AI models require significantly larger datasets and computing resources compared to traditional AI/ML algorithms.
  3. Bias and Privacy: Generative AI is more susceptible to embedded biases and privacy issues due to its reliance on diverse and unfiltered data sources.
  4. Output Risk: Generative AI models can produce plausible but inaccurate or biased outputs, which can pose risks in decision-making contexts like finance.

Challenges Posed by Generative AI for Financial Sector

The challenges posed by Generative AI (GenAI) systems for the financial sector can be categorized into four key areas: data privacy, embedded bias, model robustness, and explainability

  1. Data Privacy
    Generative AI systems introduce significant data privacy risks, especially in the highly regulated financial sector where sensitive personal and financial data is handled. Key concerns include:
    1. Data Leakages: GenAI systems might inadvertently expose sensitive financial or personal data due to insufficient safeguards in their training processes
    2. Unmasking Anonymized Data: These systems can infer sensitive information from anonymized datasets, posing risks of privacy breaches
    3. Use of Public GenAI Systems: Financial institutions using publicly available GenAI tools risk unintentionally sharing sensitive or proprietary data, which could later be exposed or used improperly by these models.
    4. Opt-In” Default Practices: Public GenAI models often default to using user-provided data for fine-tuning and training. This poses a significant privacy concern when sensitive financial data is input by users.
      Efforts like developing enterprise-level GenAI systems aim to mitigate these risks but are not foolproof. Even within these private systems, risks like inadvertent collection of personal data during web scraping remain.
  2. Embedded Bias
    Embedded bias is a long-standing concern in AI systems, but GenAI models amplify this problem. The challenges include:
    1. Training Data Bias: The responses generated by GenAI models can be heavily influenced by the input prompts, which may carry latent biases introduced by the user.
    2. Prompt-Induced Bias: The responses generated by GenAI models can be heavily influenced by the input prompts, which may carry latent biases introduced by the user.
    3. Search Engine Optimization (SEO) Manipulation: Training datasets may increasingly be skewed by content optimized for search engine rankings, introducing further biases into the system’s responses
    4. Discriminatory Financial Practices: In financial services, embedded bias in GenAI could lead to unethical practices such as unfair credit profiling, financial exclusion, or discriminatory customer service.
      These biases undermine trust in AI-supported financial services and could lead to reputational damage and regulatory scrutiny.
  3. Explainability
    Explainability is critical in the financial sector, where institutions must justify their decisions to regulators, stakeholders, and customers. Challenges include:
    1. Opaque Processes: GenAI models operate on complex architectures with millions (or even billions) of parameters, making it extremely difficult to trace how specific outputs are generated.
    2. Trade-Off with Accuracy: The more accurate and flexible the model, the harder it is to explain its inner workings and decision-making processes.
    3. Regulatory Requirements: Financial institutions must explain and justify actions influenced by AI, such as credit decisions or fraud detection. The inability to explain GenAI outputs makes compliance with regulatory frameworks difficult. 
  4.  Model Robustness
    Robustness refers to the accuracy and reliability of GenAI outputs in dynamic and sensitive financial environments. Challenges include:
    1. Hallucinations: GenAI models are prone to producing plausible but factually incorrect outputs (“hallucinations”), which can have severe consequences in financial decision-making.
    2. Dependence on Historical Data: GenAI models trained on pre-existing data may fail to adapt accurately to structural shifts or novel market conditions, leading to misleading predictions or analyses.
    3. Cybersecurity Threats: GenAI systems are vulnerable to attacks such as:
      • Data Poisoning: Malicious manipulation of training data to influence outputs.
      • Input Attacks: Techniques like “prompt injection” can bypass safeguards or corrupt the model’s outputs.
    4. Risk Amplification: Financial institutions relying on GenAI for decisions like risk assessment may inadvertently amplify systemic risks if outputs are erroneous or biased.
      Robustness issues not only threaten financial stability but also erode consumer trust in the technology.
  5. Explainability
    Explainability is critical in the financial sector, where institutions must justify their decisions to regulators, stakeholders, and customers. Challenges include:
    1. Opaque Processes: GenAI models operate on complex architectures with millions (or even billions) of parameters, making it extremely difficult to trace how specific outputs are generated.
    2. Trade-Off with Accuracy: The more accurate and flexible the model, the harder it is to explain its inner workings and decision-making processes.
    3. Regulatory Requirements: Financial institutions must explain and justify actions influenced by AI, such as credit decisions or fraud detection. The inability to explain GenAI outputs makes compliance with regulatory frameworks difficult.
    4. Hallucinations and Misinterpretation: When GenAI outputs are confidently incorrect, stakeholders may struggle to distinguish between accurate and fabricated information, further complicating explainability.
      Ongoing research in techniques like layer-wise relevance propagation and fine-tuning aims to improve explainability but remains insufficient for broad adoption in finance.
      These challenges require cautious adoption, robust safeguards, and active regulatory oversight to ensure GenAI is used responsibly in finance

Role of Synthetic Data in AI Models

Synthetic data is artificially generated data that replicates the statistical properties of real-world datasets. It is increasingly used in AI and machine learning (ML) to enhance model performance, particularly in sectors like finance, where data privacy, cost, and accessibility are major concerns

Key Uses and Benefits of Synthetic Data in AI:

  • Model Training & Testing: Helps train AI models when real-world data is insufficient, biased, or too sensitive.
  • Data Augmentation: Expands limited datasets, improving AI model performance in edge cases.
  • Regulatory Compliance: Reduces reliance on personal or sensitive data, helping institutions comply with data privacy laws (e.g., GDPR).
  • Bias Mitigation: Can balance datasets to counteract demographic, financial, or social biases in AI decision-making.
  • Cost Efficiency: Synthetic data generation is often cheaper than collecting and managing real-world datasets.
  • Cybersecurity & Fraud Detection: Used in financial services to simulate fraudulent transactions and test AI-driven fraud detection models.
    Generative AI plays a crucial role in creating synthetic data, leveraging deep learning models (e.g., GANs – Generative Adversarial Networks) to produce data that mimics real financial behaviours and patterns.

Potential Risks of Synthetic Data in AI Applications

While synthetic data offers multiple advantages, it introduces several risks that financial institutions must carefully address.

  1.  Data Quality & Reliability Issues
    • Lack of Real-World Accuracy: Since synthetic data is artificially generated, it may not always capture the complexity, noise, or anomalies present in real-world data.
    • Overfitting Risks: If synthetic data is too closely aligned with real-world data, models may overfit and fail to generalize when faced with new real-world scenarios.
    • Poor Representation of Rare Events: AI models trained on synthetic data may fail to account for rare but critical financial events (e.g., economic crises, cyberattacks).
  2. Risk of Embedding and Amplifying Bias
    • Bias Reflection from Training Data: Synthetic data inherits biases from the real-world data it is modelled after. If biases exist in the original dataset, they will persist in synthetic versions.
    • False Perception of Fairness: While synthetic data may appear diverse, it might still reinforce structural inequalities in credit scoring, loan approvals, or fraud detection models.
  3. Security & Adversarial Vulnerabilities
    • Data Poisoning Attacks: Cybercriminals can manipulate synthetic data used for training AI models, compromising decision-making.
    • Synthetic Identity Fraud: AI-generated synthetic identities can be used for fraudulent transactions, increasing financial crime risks.
    • Jailbreaking AI Models: Malicious actors may use synthetic data to circumvent security measures in AI systems, making them vulnerable to exploitation.
  4. Regulatory & Compliance Challenges
    • Legal Ambiguity: The financial sector operates under strict regulatory frameworks, and synthetic data usage is not always explicitly covered in existing laws.
    • Accountability Issues: If financial decisions are made based on synthetic data, there may be legal disputes over responsibility when errors occur.
    • Explainability & Auditing: Since synthetic data is artificially generated, explaining AI decisions made using it can be challenging, raising compliance concerns.
      While synthetic data offers significant advantages in AI development, financial institutions must implement robust governance frameworks to mitigate risks. This includes rigorous validation, bias detection, security safeguards, and regulatory alignment to ensure synthetic data enhances AI systems without introducing unintended vulnerabilities
