• Data exploration means finding the patterns and trends in the data.
• Data visualisation is the graphical representation of data and information.
• Modelling or data modelling is defined as the process of designing decision-making algorithms that have to
be trained on a set of data (which was acquired at the data acquisition stage for the problem you scoped in the
problem-scoping stage) and applying that learning to recognise certain types of patterns.
• Rule-based data modelling is based on a set of rules and a set of facts already fed to the machine to generate the
desired output.
• Learning-based data modelling refers to the model where the relationship or patterns in the data are not defined
by the developer.
• Decision trees are tools that follow a rule-based approach that uses a tree-like model of decisions and their
possible consequences.
• Evaluation is a process that critically examines a program.
• Confusion matrix is a tabular structure that helps in measuring the performance of an AI model using the test data.
• The ROC curve is a graphical representation that illustrates the performance of a binary classifier system at varying
threshold values.
• The deployment phase of the AI project cycle is when the AI model is put into use in a real-world setting.
• AI Project Cycle Mapping Template presents how different stages are related to each other and how the functions
performed in every phase form an input for the next phase.
• Ethics are rules about what is right and wrong. AI ethics are rules about using artificial intelligence (AI) in a good
way.
• AI bias is a phenomenon that occurs when an algorithm produces results that are systematically prejudiced towards
certain gender, language, race, wealth, etc., and therefore, produces skewed or learned output.
