How to Make an AI: A step by step process

Currently, 40% of global companies leverage AI to automate workflows, refine marketing strategies, and improve customer support. And, the global AI market is projected to soar to $1.85 trillion by 2030 (Source). 

In practical terms, AI powers tools we interact with daily, from chatbots and personalized recommendations to fraud detection systems. So, first…

Step 1: Define your AI goals & use case

Before diving into AI development, clarity is key. Building AI without a clear direction is like setting sail without a map—you might move, but you won’t get anywhere meaningful. 

Steps to define your goal and use cases

Identify the problem you want to solve: AI thrives when it addresses real-world challenges. Start by asking:

• What problem are we solving?
• How will AI add value to our process or product?
• Who will benefit from this AI solution?

For example, our in-house project WriteWise AI, is designed to simplify content creation for businesses and individuals by offering an intuitive AI-powered writing assistant.

Define your objectives and metrics for success: Once you identify the problem, establish clear objectives. Do you want to automate tasks, enhance customer experiences, or improve decision-making? Alongside this, define key performance indicators (KPIs) to measure your AI’s success, such as:

• Increased efficiency (e.g., processing time reduction).
• Improved accuracy (e.g., error rate reduction in predictions).
• Enhanced user satisfaction (e.g., survey ratings).

 Narrow down the use case: AI can do a lot, but starting small ensures focus and scalability. For example:

• Customer Support: Automate FAQs using AI chatbots.
• Marketing: Personalize recommendations with machine learning algorithms.
• Operations: Predict demand using data analytics.

By defining your AI goals and use case, you set the foundation for your project that delivers real, and measurable value. 

Step 2: Feasibility analysis and resource planning

Once your AI goals and use cases are defined, the next step is to assess feasibility and plan your resources effectively to ensure you’re building a solution that is practical, achievable, and aligned with your capabilities.

Key steps for analysis and resource planning

Conduct a feasibility study: Evaluate whether your proposed AI solution is technically and economically viable. To do this focus on:

• Data Availability: Does sufficient, high-quality data exist for training your AI model?
• Technological Requirements: Can current tools and technologies support your goals?
• Budget Constraints: Is your budget sufficient to cover development, deployment, and maintenance?
• Regulatory Compliance: Are there legal or ethical constraints, such as GDPR for data privacy?

For example, building an AI resume builder like our project SeekrCareers requires access to anonymized resume data and compliance with privacy laws to protect user information.

Assess your team and skills: AI development demands specialized skills. So, assess your team’s expertise in areas like:

• Machine Learning Algorithms
• Programming Languages (e.g., Python, R)
• Data Engineering
• Cloud Platforms (e.g., AWS, Azure)

If skills are lacking, you can choose to hire keras developer with deep learning expertise, or partner with an experienced AI development company

Plan your infrastructure: Otherwise, start to plan your infrastructure by  choosing the right tools and platforms that meet your needs:

• Cloud Platforms: For scalability and cost-efficiency (e.g., AWS Sagemaker, Google AI).
• Open-Source Libraries: TensorFlow, PyTorch, or Scikit-learn for faster prototyping.

Hardware Requirements: GPUs or TPUs for deep learning tasks.

Budget and timeline estimation: Next, break down the project into phases and estimate costs and timelines for:

1. Data acquisition and preprocessing.
2. Model development and testing.
3. Deployment and maintenance.

Step 3: Data collection and preparation

Data is the backbone of any AI project. Without high-quality data, even the most sophisticated AI algorithms will fail to deliver accurate results. 

Data collection process

Identify data sources: Your AI system will only be as good as the data it’s trained on. Depending on your use case, data sources may include:

• Internal Databases: Existing customer or operational data.
• Public Datasets: Open-source data repositories (e.g., Kaggle, UCI Machine Learning Repository).
• Web Scraping: For collecting real-time data from websites (ensure legal compliance).
• APIs: External services offering structured data (e.g., social media, weather, or financial APIs).

For example, WriteWise AI utilized diverse datasets like articles and blogs to train its language models for varied writing styles and tones.

Ensuring the quality, validity, and integrity of data is fundamental—especially when working with user-generated information such as email addresses. Leveraging third-party APIs can add an additional layer of security and reliability to your AI project. For example, before integrating emails into your training dataset or customer communications workflow, you can assess the reputation of an email address using a dedicated API. This helps to reduce spam risks, prevent fraudulent activities, and improve your model’s overall trustworthiness by filtering out suspicious or low-quality inputs.

Ensure data quality: High-quality data is critical for accurate AI predictions. Evaluate and improve:

• Completeness: Are there missing values?
• Accuracy: Is the data correct and consistent?
• Relevance: Is the data aligned with your AI goals?
• Balance: Avoid skewed datasets that can lead to biased models.

Clean and preprocess data: Data rarely comes ready for AI. Preprocessing steps include:

1. Removing Noise: Eliminate irrelevant or redundant information.
2. Handling Missing Data: Fill gaps using imputation techniques or remove incomplete records.
3. Normalizing Data: Scale features to ensure uniformity, especially for algorithms sensitive to value ranges.
4. Encoding Data: Convert categorical variables into numeric values using one-hot encoding or label encoding.
5. Data Augmentation: For limited datasets, apply techniques like rotating or flipping images for diversity.

Address data security and ethics: Respect user privacy and comply with legal frameworks. For instance:

• Anonymize sensitive data to protect identities.
• Store data securely using encryption protocols.
• Follow global regulations like GDPR, HIPAA, or CCPA.

Automate data pipelines: Consider creating automated pipelines for continuous data collection, cleaning, and integration. Tools like Apache Kafka or Airflow can streamline this process.

Step 4: Exploratory Data Analysis (EDA)

EDA not only gives you a deeper understanding of your dataset but also helps in refining your AI model design. It ensures that the data you’re using is appropriate and aligned with your AI objectives. Result: minimize errors in the later stages by identifying issues such as missing values, outliers, or irrelevant features early on.

Key steps in EDA

Understand the Dataset:

• Examine data types, dimensions, and basic statistics (mean, median, variance).
• Use summary functions to identify inconsistencies or anomalies.

Visualize the Data: Leverage tools like Matplotlib, Seaborn, or Tableau for charts and graphs.

Common visualizations include:

• Histograms for distribution.
• Scatterplots to examine relationships.
• Boxplots to identify outliers.

Analyze Correlations: 

• Use correlation matrices to identify how features relate to each other.
• Remove redundant features that don’t add value to the model.

Handle Missing Values and Outliers:

• Impute missing data using mean, median, or predictive models.
•  Remove or adjust outliers to prevent skewed predictions.

Feature Engineering:

• Create new features that better represent the underlying data.
• For example, if time data is provided, derive features like “hour of day” or “day of week.”

Step 5: Model selection and design

Once you’ve explored and refined your data, it’s time to choose the right AI model and design its architecture. The success of your AI system largely depends on selecting a model that aligns with your use case and data characteristics.

Key Considerations

Type of Problem:

• Classification: For problems like spam detection or image labeling.
• Regression: For predicting continuous values like sales or temperatures.

Clustering: For grouping similar data points, e.g., customer segmentation.

Data Size and Complexity:

• For small datasets, simpler algorithms like Decision Trees or Logistic Regression may suffice.
• For large and complex datasets, advanced models like Random Forests or Neural Networks are more effective.

Explainability vs. Performance:

• In industries like healthcare, interpretable models (e.g., Linear Regression) are often preferred.
• For tasks requiring high accuracy, black-box models (e.g., Deep Learning) might be more suitable.

Designing the model architecture

If using deep learning, architecture design is critical. Key decisions include:

• Number of Layers: How deep should the neural network be?
• Type of Layers: Choose from dense, convolutional, or recurrent layers based on the task.
• Activation Functions: Use ReLU, sigmoid, or softmax based on output requirements.

Experiment with Pre-Trained Models

Try to use pre-trained models like GPT, BERT, or ResNet, to save time and resources. These models are trained on massive datasets and can be fine-tuned for your specific needs. Otherwise, you can find pre-trained models from AWS and Kaggle.
