Building an Artificial Intelligence Proof of Concept

A Comprehensive Playbook

At FullStack, we have partnered with leading research organizations, national logistics firms, and more to develop their cutting-edge AI proofs of concepts (PoCs). PoCs help companies assess feasibility and optimize their products before full development. This playbook details the FullStack Labs methods for building a best-in-class AI PoC.

What is an AI POC?

An AI Proof of Concept (PoC) is a small-scale prototype project designed to demonstrate an AI solution's feasibility and potential impact. It enables us to assess the technical viability, assess the performance, and identify any potential issues. A PoC also helps you estimate costs and timelines for production, delivery, and architecture before committing to a full-scale implementation.

AI Research Assistant Proof of Concept

Before developing a full AI solution, we designed a PoC of an AI Research Assistant for a leading research institution. The proof of concept helps clients gain insight reports and book time with analysts in seconds—but operates on a limited dataset. It is now being scaled up and built into a full solution with access to a full research library.

Phase 1

Key Deliverables

Phase 3

Data Preparation

Building the Foundation of Your AI PoC

Proper data preparation is critical to the success of your AI model. We focus on gathering, cleaning, and transforming data to create a solid foundation for training and validation. This phase includes multiple sub-steps to prepare your data for use.

Gather Existing Training Data

Before writing a single line of code, we plan each stage of development. This includes assembling a skilled app development team, completing design-to-development handoffs, establishing key project milestones, and outlining sprints and stories for efficient progress.

Data Access

The first crucial step is accessing existing training data. Our team identifies and retrieves all relevant data sources available, which might be stored in databases, cloud storage, or other repositories. We ensure that the team has the correct permissions and access rights.

Data Cleaning

Data cleaning involves removing inaccuracies and inconsistencies within your datasets. At this step, we ensure the data is accurate, complete, and error-free. Techniques include handling missing values, removing duplicates, and correcting or removing corrupt records.

Data Transformation (ETL)

ETL (Extract, Transform, Load) is the process of extracting data from various sources, transforming it into a suitable format or structure for analysis, and loading it into a data warehouse or other target system. This step often involves normalization, aggregation, and other transformation techniques to make the data usable.

Data Splitting

Splitting the data into training and testing sets is a fundamental step in preparing your data. We ensure your AI PoC model can be trained on one subset of the data and validated or tested on another, measuring its performance.

Work with SMEs to Create More Training Data

Collaborating with Subject Matter Experts (SMEs) can help generate additional training data. SMEs provide insights and context that might not be apparent from the data alone, enabling the creation of a more comprehensive dataset.

Use Generative AI to Synthesize Training Data

If the project requires additional data, we can synthesize it. Generative AI can create synthetic data that mimics the characteristics of real-world data. Generative models such as GANs (Generative Adversarial Networks) can produce high-quality synthetic data to enhance the training dataset.

Set Aside Data for Validation Purposes

Creating a separate validation dataset is crucial for evaluating the model’s performance during training. Your AI development engineers use the validation set to tune model parameters and decide on which models to use, ensuring that the model generalizes well to unseen data.

Analyze the Data to Ensure Quality and Relevance

Data analysis involves examining the data to ensure it is of high quality and relevant to the problem at hand. This includes statistical analysis, visualization, and exploratory data analysis (EDA) to understand the underlying patterns and relationships within the data. Analyzing the data helps identify any biases or anomalies before proceeding to model training.

Data Preparation with Rigorous Standards

During the data preparation phase, our team ensures meticulous gathering, cleaning, and transformation of data, laying a solid foundation for your AI model. This phase verifies that all data processes align with project goals and quality standards. Upon completion, your data will be thoroughly prepared for the subsequent model training phase, ensuring accurate and reliable results.

Technology Selection & Modeling

Choosing the Right Tools for the Job

New technology emerges almost weekly, and selecting the appropriate machine learning (ML) models is critical. This phase involves evaluating and identifying the best candidate models that align with your project’s objectives and data characteristics.

Assess Machine Learning Models for Suitability

We begin by exploring available machine-learning models that could solve the problem at hand. This includes traditional models (like linear regression, decision trees, and SVMs) and advanced models (such as neural networks, LLMs, and ensemble methods). We evaluate each model based on several criteria:


Assess the historical performance of the models on similar datasets.


Determine if the model can handle the size and complexity of your data.


Ensure that the model is compatible with your existing technology stack.

Ease of Implementation

Consider the complexity of implementing and tuning the model.

Resource Requirements

Evaluate the computational and time resources needed for training and inference.

Identify Candidate Solutions for PoC Trial

Based on the evaluation, FullStack narrows down a shortlist of candidate models.  These models should meet the initial criteria and show promise in preliminary tests.
