AI inference uses a trained artificial intelligence (AI) model to make predictions, classify, or generate new data based on the patterns and relationships learned from a training dataset.

In other words, AI inference is the application of AI models to real-world data to extract insights, make decisions, or automate tasks.

This crucial step in the AI development process allows AI models to be deployed and used in practical applications across various industries, from healthcare to finance to retail.

Types of AI Inference

1. Classification

Classification is a type of AI inference where models are trained to classify new data into predefined categories or classes. This technique is widely used in applications such as:

  • Spam Detection: Email systems use AI to classify incoming messages as spam or legitimate.
  • Image Recognition: AI models can classify images, such as identifying objects, animals, or faces.
  • Sentiment Analysis: AI can classify text data to determine the sentiment, whether positive, negative, or neutral.

2. Regression

Regression involves training AI models to predict continuous values or numerical outputs. Some typical applications include:

  • Stock Price Prediction: AI models can forecast future stock prices based on historical data.
  • House Value Estimation: Real estate platforms use AI to predict the value of a property based on various factors.
  • Weather Forecasting: Meteorological data is analyzed to predict weather conditions.

3. Clustering

Clustering is used to group similar data points into clusters or segments. It is often applied in:

  • Customer Segmentation: Retailers use AI to segment customers based on purchasing behaviour.
  • Market Research: Companies analyze market trends by clustering similar data points.
  • Anomaly Detection: Identifying outliers in data, such as fraudulent transactions or defective products.

4. Generation

Generation refers to AI models creating new data, such as text, images, or audio. This is prevalent in creative fields like:

  • Content Generation: AI can write articles, create social media posts, and generate books.
  • Image Synthesis: AI models can create realistic images, such as generating faces that do not exist.
  • Music Composition: AI can compose original music, providing new melodies and harmonies.

Techniques Used in AI Inference
