Apache Airflow is a platform to programmatically author, schedule, and monitor workflows; it is not simply a task scheduler. While Cron allows you to run scripts at specific times, Airflow allows you to define complex dependencies between them. It transforms isolated scripts and fragile batch jobs into a resilient, code-based ecosystem.

The Activation Function is a mathematical rule that determines the output of a neuron, taking as input the weighted sum of the neuron's inputs. It decides if and how the neuron should influence the network's output.

An accuracy score is an evaluation metric used to estimate a machine learning model’s performance, showing the ratio of the number of correct predictions to the total number of predictions.

An AI Chatbot is intelligent software that uses natural language processing (NLP) and artificial intelligence to converse with humans through text or voice interfaces.

Artificial Intelligence (AI) is the simulation of human intelligence processes by computer systems. These processes include learning from experience (machine learning), understanding natural language, recognizing patterns, solving problems, and making decisions. AI systems can analyze vast amounts of data, identify trends, and perform tasks that traditionally required human intelligence, such as visual perception, speech recognition, and decision-making.
