How does AI Work?

Artificial intelligence works in a systematic way. It consists of a combination of algorithms, data, and computing powers.

Data collection

The first step for artificial intelligence is collection of data. It can be collected through various sources, sensors, databases or internet.

Data processing

After collection, data must be processed before training an AI model. This consists of cleaning of data, removing outliers, and taking care of missing or null values. 

Training the model

After our data is processed successfully, we train the model, The model identifies the hidden patterns, relationships, and correlations among the data. 

Model Testing

Netx, the trained model, is tested against some data values. It is assessed for its performance and accuracy.

Deployment

Once our model is ready, it is deployed to make predictions for new, unseen data. Once the model is deployed, it is then designed to continuously learn and predict new unseen values. Hence, increasing its accuracy and efficiency. 

Types of Artificial Intelligence

There are many types of artificial intelligence.
