AI Model Training: Everything You Need to Know

Data and computational power are the lifeblood of modern-day artificial intelligence (AI). Though AI requires powerful computers to work its magic and drive its awesome capabilities, AI models still depend on top-quality data to execute user commands and complete the task at hand.

So, what is AI training exactly? It's the process of teaching an AI model to learn and perform better by learning from vast amounts of web data. Our comprehensive guide offers a thorough overview of AI training, complete with actionable examples.

This article also covers core methods and the necessary steps to create an AI training workflow for developers. We’ll also delve deeper into using tools like Oxylabs to build AI-powered data pipelines and the best ways to scale your projects.

Core AI Training Methods

Even the most advanced AI-powered solutions require high-end data to function. The best way to obtain the required amount of high-quality data for AI training is through automated collection.
Through AI training, your AI models learn to perform specific tasks, such as targeting popular websites and extracting structured data that you can turn into actionable insights. The training process involves feeding quality data to your AI model, fine-tuning its parameters, and evaluating its performance with separate test sets to ensure optimal performance.

There are three core AI training methods you can tap into to teach your AI agents to complete any task:

• Supervised learning: Algorithms like support vector machines and linear regression help models learn from labeled datasets. The model processes this data to recognize patterns and make accurate predictions on new data.

• Unsupervised learning: This method teaches your model to identify structures and patterns using unlabeled data and algorithms such as principal component analysis. It doesn't require user guidance and is ideal for tasks like clustering data points.

• Reinforcement learning: AI models learn through trial and error. Each action brings a potential reward or penalty, allowing the agent to make more informed decisions over time.

Before using any of these methods, make sure you select the right model architecture, algorithms, tools, and computing resources for your project. You also need to consider ethical concerns regarding data extraction, legal compliance, and data privacy.

Detailed 7-Step Training Workflow

Here are the detailed steps to create a personalized AI training workflow that will work for you, regardless of your level of skill.

1. Problem definition

Start by defining a clear problem for your AI model to solve. This helps you acquire the right datasets. The goal could be anything from new content creation to more effective fraud prevention.

2. Data collection

Next, you need diverse, accurate, and up-to-date AI training data. Your AI agent depends on relevant datasets to function. The best way to obtain enough data is to use a reliable and scalable web scraping tool that can quickly browse top data sources and extract the required information, including text, audio/video files, images, etc.

3. Data preprocessing

Once you acquire the data, use processing techniques to organize it and remove inconsistencies. Preprocessing ensures top data quality by eliminating noise, validating accuracy, and converting the data into the correct format for your chosen algorithm.

4. Model selection

The next step is to choose the right AI model for the training.
You have two options here:

• Machine learning model – learns through data analysis to identify patterns, make decisions, detect anomalies, recognize trends, and classify information without explicit coding.

• Generative AI – employs AI techniques such as NLP, deep learning, and neural networks to generate fresh, real-time content.

If you need an AI model that can create fresh content, including text, images, audio, and video, we recommend generative AI. For any other use case, machine learning fits better.

5. Training & tuning

After selecting a model, you need to choose a matching training technique. For machine learning, this could be supervised or unsupervised learning. For generative AI, techniques include:

• Transformers – help an AIa model learn to understand the deeper context and meaning of the training datasets by recognizing the relationship between sentences and sequence entities.

• GANs (Generative Adversarial Networks) – an AI model learns to distinguish between real and fake (synthetic or artificial) data using the generator and the discriminator neural networks. The goal is to teach your model to better detect fake data by telling what’s genuine and what’s artificial.

• Diffusion – a training technique based on visuals, such as realistic images, that teaches an AI model to transform raw data, full of noise, into a structured output.

Feed the preprocessed data to your AI agent and monitor the process to fix errors. Keep an eye on problems like overfitting, where the model only memorizes data instead of drawing actionable conclusions.

6. Evaluation
Test your model periodically to fine-tune its performance. Feed it independent datasets it hasn’t seen before. If it performs below your expectations, fine-tune it with more data and retrain it to minimize errors.

7. Deployment & monitoring
When your AI model is ready in full, it’s time to deploy it. You can do so via an app, API, or in a cloud environment. Monitor its performance continuously to address any issues as they arise. You’ll need to retrain it from time to time to scale and keep it relevant.

Building Data Pipelines with Oxylabs Tools

The quality, accuracy, and performance of your AI model solely depend on the quality of the datasets in its database. Web data is vital to AI training, allowing your AI agent to refine its actions and improve its accuracy and performance with each new interaction.

With that in mind, let’s delve into the three essential workflows that directly determine the success of your AI training model. These include data extraction using a web scraper, data preprocessing to eliminate irrelevant information, and data organization to format the training data appropriately. Once you get ahead of these workflows, you can build automated data pipelines to ensure your AI model has enough training data at all times.

Whether you need an e-commerce data pipeline for your next project or SERP results, you can easily integrate a web scraper API like the one from Oxylabs with scraped public data to upgrade any AI tool you can think of.

Here’s how it works. First, you use the Oxylabs Web Scraper API to scrape and extract the data for your pipeline. This method makes it easy to parse the extracted data and store it in a structured format like CSV or JSON. It’s ideal for extracting product URLs, prices, titles, and availability rates in an organized manner.

For example, here’s a basic Python script to make a request:

import requests
import json

# API credentials
username = 'YOUR_USERNAME'
password = 'YOUR_PASSWORD'

# API endpoint
api_url = 'https://api.oxylabs.io/v1/queries'

# Request payload
payload = {
    'source': 'universal',
    'url': 'https://example-ecommerce.com/products/laptops',
    'content_type': 'json',
    'user_agent_type': 'desktop',
    'geo_location': 'United States',
    'render': 'true'
}

# Make the request
response = requests.post(
    api_url,
    auth=(username, password),
    json=payload
)

# Process the response
if response.status_code == 200:
    data = response.json()
    print(json.dumps(data, indent=2))
else:
    print(f"Error: {response.status_code}")

Next, you feed the extracted data to the Assistants API for further analysis and processing to prepare it for your pipeline. You can simply pass the JSON file directly to the user’s message to attach it to an existing vector store or create a new vector store automatically.

Alternatively, you can just copy the contents of your JSON file and add them to the user’s message. However, this method will only work for smaller pipelines. For more complex projects involving larger datasets, the file upload method is more reliable and cost-effective. For more information, check the Oxylabs Web Scraping Architecture guide.

Once you have the data, you can start the preprocessing steps, such as parsing the JSON output to extract specific fields:

# Assuming 'data' is the JSON response from the previous example
# This is a simplified example of data cleaning
scraped_items = data['results'][0]['content']['items']
clean_products = []

for item in scraped_items:
    product = {
        'title': item.get('title'),
        'price': item.get('price'),
        'in_stock': item.get('availability') == 'In Stock'
    }
    clean_products.append(product)

print(f"Processed {len(clean_products)} products.")

Infrastructure & Scaling

AI training is a resource-intensive task. It requires extensive hardware resources and power, including cooling, storage, memory, and processing power.

In other words, you’ll need SSDs, RAM, GPUs, and CPUs, as well as specialized accelerators like FPGAs (Field-Programmable Gate Arrays) and TPUs (Tensor Processing Units) for AI training.

Here are a few hardware recommendations:

• AMD EPIC and Intel Xeon multi-core CPUs are ideal for efficient data preprocessing;

• Cutting-edge, high-VRAM GPUs are perfect for the parallel processing of large datasets used for AI training models;

• 64GB of RAM or more is required for a memory-intensive task like AI training;

• TPUs and FPGAs help with customized AI acceleration and deep learning tasks;

• Use PSU systems and liquid cooling to ensure your AI training project goes smoothly.

We recommend training at scale using distributed computing for AI models that depend on large datasets. That includes distributing the training frameworks across multiple computers, equipped with appropriate infrastructure and high-speed networking. In addition, we also recommend paying attention to API key management and logging.

Always avoid storing your API keys in public repositories. Logging, on the other hand, helps you ensure optimal AI model performance even in unexpected conditions. It also helps you understand how to improve your model’s operating efficiency.

In case you experience any scaling problems, resolve them using proxies to help bypass IP blocks and bans, and ensure you extract enough data to properly scale your AI infrastructure.

Challenges, Ethics & Legal Tips

AI training comes with various challenges, including ethical and legal concerns. First of all, there’s data bias to think about. It occurs when your AI model starts reinforcing stereotypes, leading it to make biased decisions and provide negative or unfair outcomes.

If you feed it biased datasets, your AI model might express biased behavior that will further impact its decision-making and prediction processes. If left untreated, such behavior and performance could lead to regulatory and legal consequences. Then, there are ethical concerns regarding AI model training.

These include responsible scaling, legal compliance, and data privacy regulations. To address these concerns and ensure legitimate training use cases, you must align your practices with regulations like GDPR and CCPA. There are also scraping-specific issues to keep in mind.

For example, you could get your IP banned while trying to extract the training data for your AI model. Or you could face legal repercussions due to unethical scraping. Most websites keep scraping rules in the robots.txt file. We recommend following these instructions to avoid unnecessary risks.

CloudFlare recently introduced new AI scraping rules in an attempt to reinforce a permission-based AI scraping model. According to that, an AI training company will have to ask for permission from the target source before scraping and extracting information. So, keep all this in mind before launching an AI model training operation.

Advanced Use Cases

Trend prediction is the best example of how effective an AI model can be. It helps companies predict the next trend in their industry using AI. For example, they can use AI to estimate the demand for their services.

To create such a model, a company would need a reliable data pipeline to feed its AI with the right type of information. So, first, they need to identify the websites with the right data for their model. Then, they need a scraper like Oxylabs to extract the data and transform it into a pipeline-friendly format like CSV or JSON.

Next, they must choose the matching AI model for trend prediction and use the prepared data pipeline to train their agent. Afterwards, they must assess the model’s performance to make the necessary adjustments and prevent issues like overfitting. Now, your model is ready to start predicting upcoming trends.

Another great example is obtaining training data for LLMs (large language models). LLM training requires vast amounts of data. To gather such data, you’ll need an effective scraper like Oxylabs that can handle various public data sources and bypass strict anti-scraping measures.

Once Oxylabs obtains the data, create or choose an LLM training model, train, and fine-tune your LLM agent by modifying hyperparameters, such as warmup steps, gradient clipping, batch sizes, learning rates, etc.
