In simple terms, an AI model is a tool or algorithm which is based on a certain data set through which it can arrive at a decision – all without the need for human interference in the decision-making process. An AI model is a program or algorithm that utilizes a set of data that enables it to recognize certain patterns. This allows it to reach a conclusion or make a prediction when provided with sufficient information, often a huge amount of data. Hence, AI models are particularly suitable for solving complex problems while providing higher efficiency/cost savings and accuracy compared to simple methods.
