This is a streamlined processes integrated within FinacneGPTs architecture that facilitate the seamless transformation of raw data into actionable insights. These pipelines are carefully designed to preprocess input text, manage data flow through the model's layers, and post-process the output to generate coherent and contextually appropriate responses. The pipelines handle tasks such as tokenization, embedding, attention mechanism management, etc.

Model Pre-training

FinanceGPT was pre-trained phase where it is trained on a massive dataset of text or code. This extensive exposure allows the model to learn a wide range of linguistic patterns, syntactic structures, and semantic relationships. During pre-training, BookGPT identifies and extracts meaningful features from the text, developing an internal representation of language that captures the intricate relationships between words, phrases, and sentences. This comprehensive understanding forms the foundation for downstream tasks, enabling BookGPT to transfer its knowledge effectively to new domains and applications, enhancing its versatility and performance in various contexts.

Remediations

Model Remediation

Unique is constantly trying to make FinanceGPT as holistic and accurate as possible. With a robust model remediation process, we can adjust the model based on the output of its training.

• Issue Identification: The first step involves detecting problems with the model's outputs, such as biases, inaccuracies, generation of harmful content, or lack of adherence to ethical guidelines

• Root Cause Analysis: Once issues are identified, it's important to understand why they are occurring. This could be due to biases in the training data, flaws in the model architecture, or limitations in the training process

• Model Retraining: If the underlying cause is related to the data the model was trained on, retraining the model with remediated or augmented datasets can help correct the issues

• Architecture Adjustments: Sometimes, the architecture of FinanceGPT itself may need to be modified. This could involve changing the neural network layers, activation functions, or other architectural elements to improve the model's performance

• Fine-tuning: In some cases, further fine-tuning of the model on curated datasets helps to correct specific issues without a full retraining cycle

• Hyperparameter Optimization: Adjusting the hyperparameters, such as learning rate, batch size, or regularization terms, sometimes mitigates issues by altering the learning process

• Reinforcement Learning from Human Feedback (RLHF): Feedback from our client's experience of using FinanceGPT is highly valuable to guide the model towards more desirable outputs. This can be an effective method for teaching the model the nuances of what is considered appropriate or high-quality content

Data Remediation

The quality and integrity of the data FinanceGPT is trained on is crucial for its performance. If the training data contains errors, biases, or problematic content, these issues can be reflected in the model's output. Especially for FSI clients, it is very important to mitigate these as much as possible.

We have, therefore, implemented steps to counter this:

• Data Cleaning: Identifying and correcting errors or inconsistencies in the data, such as typos, formatting issues, and incorrect labels.

• Bias Mitigation: Detecting and addressing biases in the data to prevent the model from perpetuating or amplifying these biases in its responses

• Data Filtering: Removing low-quality, irrelevant, or harmful data from the training set to ensure the model learns from high-quality information

• Data Enrichment: Easily adding new, high-quality data to the training set to improve the model's knowledge and capabilities, particularly in underrepresented domains

• Data Anonymization: Ensuring that personally identifiable information (PII) is removed or obscured to protect privacy and comply with regulations

• Data Validation: Using various techniques to validate the accuracy and relevance of the data before it's used in training (see also: https://unique-ch.atlassian.net/wiki/x/SQEFGg )

Prompt Remediation

The quality of output of FinanceGPT is heavily influenced by the input. In general, high-quality prompts lead to a significant increase in the performance output.

• Clarifying Ambiguity: Rewriting prompts to be more specific and clear to reduce ambiguity and help the model generate more precise responses.

• Reducing Bias: Adjusting prompts to minimize the potential for biased outputs, which may involve rephrasing or providing a more balanced context.

• Ensuring Context: Providing sufficient background information in the prompt to guide the model in understanding the context and generating relevant responses.

• Guiding Content: Including instructions or constraints within the prompt to direct the model away from generating undesirable content and towards producing outputs that adhere to ethical guidelines or content policies.

• Iterative Refinement: Using an iterative approach where the initial output is assessed, and the prompt is refined based on the model's response to improve the result.

• Incorporating User Feedback: Using feedback from users to understand how prompts can be misunderstood or misinterpreted by the model, and adjusting them accordingly.

• Chain of Thought Prompting: Crafting prompts that include an explicit reasoning process, which can help the model generate more thoughtful and detailed responses.

Adversarial Remediation

We try to identify and mitigate weaknesses or vulnerabilities that could be exploited by adversaries as much as possible. By strengthening FinanceGPT against adversarial attacks, which are techniques that attempt to fool machine learning models with deceptive input we can mitigate undesired or harmful output.

• Adversarial Attack Identification: The first step is to identify potential adversarial attacks. This involves understanding how an adversarial example or input could be crafted to mislead the AI model

• Model Assessment: FinanceGPT is tested using these adversarial examples to see if it can be tricked into making incorrect predictions or classifications

• Vulnerability Analysis: If the model is found to be vulnerable, the specific weaknesses that allowed the adversarial attack to succeed are analyzed

• Remediation Strategies: We dynamically adjust our strategy depending on the attack. This could involve retraining the model with a more diverse dataset that includes adversarial examples, altering the model architecture, applying defensive techniques like adversarial training, or implementing input validation mechanisms to detect and reject adversarial inputs.

• Implementation: The chosen remediation strategies are implemented to enhance the model's robustness against adversarial attacks.

• Continuous Monitoring and Testing: The model is continuously monitored and tested to ensure that the remediation is effective and to identify any new potential vulnerabilities.

Prompt Injection Remediation

Prompt injection attacks occur when a user intentionally crafts an input (or prompt) to manipulate the AI into performing actions or generating responses that it shouldn't, such as revealing sensitive information, generating harmful content, or behaving in unintended ways.

The remediation process for prompt injection typically involves several key steps:

• Detection: The first step is to detect potential prompt injections. This can be done through monitoring for unusual patterns in user inputs, such as inputs that contain certain command-like structures or attempts to directly interface with the underlying model in an unauthorized way.

• Analysis: Once a potential prompt injection is detected, the input is analyzed to understand how it is trying to manipulate the model. This might involve looking for hidden commands, unusual syntax, or other indicators that the input is not a standard user query.

• Response Rules: Based on the analysis, rules or patterns are created to identify and block similar prompt injection attempts in the future. This could involve creating a list of banned phrases, patterns, or implementing more sophisticated natural language understanding algorithms to detect when the model is being prompted inappropriately.

• Model Training: The language model may be retrained or fine-tuned to recognize and resist prompt injection attempts. This training can include exposure to adversarial examples so that the model learns to respond to them appropriately.

• Policy Enforcement: Implementing and enforcing policies that define acceptable and unacceptable uses of the AI system can also help mitigate prompt injection attacks. Users can be informed of these policies, and actions can be taken against those who violate them.

• User Input Sanitization: Before processing user inputs, they can be sanitized to remove or neutralize elements that could lead to prompt injection. This might involve stripping out certain characters, using input validation techniques, or rephrasing inputs in a way that reduces the risk of manipulation.

• Continuous Improvement: As attackers develop new methods, we constantly monitor relevant security news to stay on top of new attack vectors.
