Integrating Human Feedback for Better Agent Evaluation with Evals.do

In the rapidly evolving world of AI, ensuring the quality and performance of your AI functions, workflows, and agents is paramount. While automated metrics provide a valuable baseline, true excellence often lies beyond what algorithms alone can measure. This is where human feedback becomes indispensable, especially when evaluating complex AI agents.

This blog post will delve into why integrating human feedback is crucial for robust AI agent evaluation and how Evals.do, the comprehensive AI component evaluation platform, makes this process seamless.

Why Human Feedback is Essential for AI Agent Evaluation

AI agents, whether they're customer support chatbots, data analysis tools, or content generators, interact with users in nuanced ways. Their success isn't always quantifiable by simple accuracy scores or processing speed. Consider these points:

• Understanding Nuance and Context: Humans can discern subtle meanings, interpret sentiment, and understand context that automated systems often miss. An agent's response might be technically accurate but entirely unhelpful or even offensive in context.
• Subjective Quality Assessment: Metrics like "helpfulness," "tone," and "appropriateness of language" are inherently subjective. While you can train AI to identify some aspects, ultimately, human judgment is superior for these qualitative assessments.
• Discovering Edge Cases and Unexpected Behaviors: Humans are excellent at identifying bizarre or unexpected agent behavior that automated tests might not be designed to catch. This is vital for uncovering blind spots in your AI's understanding or logic.
• Reflecting Real-World User Experience: The ultimate goal of an AI agent is to serve its users effectively. Human feedback directly captures the user experience, providing invaluable insights into how well the agent meets their needs and expectations.
• Training Data Feedback Loop: Human evaluations can inform the creation of new training data or labels, helping to fine-tune and improve your AI models over time.

How Evals.do Facilitates Human-in-the-Loop Evaluation

Evals.do is designed from the ground up to provide comprehensive, customizable evaluations for all your AI components. A core strength of the platform is its flexibility in integrating various evaluators, including the critical human element.

Let's look at how Evals.do makes this happen, using an example of evaluating a customer support agent.

import { Evaluation } from 'evals.do';

const agentEvaluation = new Evaluation({
  name: 'Customer Support Agent Evaluation',
  description: 'Evaluate the performance of customer support agent responses',
  target: 'customer-support-agent',
  metrics: [
    {
      name: 'accuracy',
      description: 'Correctness of information provided',
      scale: [0, 5],
      threshold: 4.0
    },
    {
      name: 'helpfulness',
      description: 'How well the response addresses the customer need',
      scale: [0, 5],
      threshold: 4.2
    },
    {
      name: 'tone',
      description: 'Appropriateness of language and tone',
      scale: [0, 5],
      threshold: 4.5
    }
  ],
  dataset: 'customer-support-queries',
  evaluators: ['human-review', 'automated-metrics']
});

In this Evals.do configuration:

1. Defining Custom Metrics: You're not limited to predefined metrics. Evals.do allows you to define custom metrics like helpfulness and tone, which are perfect candidates for human evaluation. You can set a scale (e.g., 0 to 5) and a threshold for what constitutes acceptable performance.
2. Targeting Specific AI Components: The target field (customer-support-agent in this case) ensures your evaluation focuses on the right component. This could be a specific function, workflow, or an entire agent system.
3. Leveraging Datasets: By specifying a dataset (customer-support-queries), Evals.do knows which inputs to feed your agent for evaluation. This ensures consistency and scalability in testing.
4. Integrating Diverse Evaluators: The key line for human feedback is evaluators: ['human-review', 'automated-metrics']. Evals.do allows you to combine different evaluation methods.
   • human-review: This designates that certain aspects of the evaluation will require human input. Evals.do then orchestrates the workflow for human reviewers to assess the agent's performance against the defined metrics.
   • automated-metrics: Simultaneously, Evals.do can run automated checks (e.g., for factual accuracy where quantifiable) to provide a combined, comprehensive score.

How Does Evals.do Work with Human Input?

Evals.do streamlines the process of collecting human feedback:

• Customizable Evaluation Criteria: As shown in the code example, you define what needs to be evaluated (e.g., helpfulness, tone) and how it should be scored.
• Workflow for Reviewers: Evals.do provides the framework for presenting agent outputs to human reviewers, along with the specified metrics and a clear interface for submitting their scores and comments. This could be integrated into your existing annotation tools or internal dashboards.
• Data Aggregation and Reporting: Once human reviewers complete their assessments, Evals.do aggregates this data with any automated metrics. This produces comprehensive performance reports, giving you a holistic view of your agent's quality.
