What is Artificial Intelligence?
Artificial intelligence is the imitation of human intelligence processes by computers, specifically computer systems. These processes include learning, reasoning, and self-correction. AI systems are designed to perform tasks that typically require human intelligence, such as decision-making, problem-solving, understanding natural language, and learning from experience.Â
Artificial intelligence is divided into several subfields, including machine learning, natural language processing, computer vision, robotics, and expert systems. Artificial Intelligence has numerous applications across industries, including healthcare, finance, transportation, entertainment, and more, and its development continues to advance rapidly.

What is data science?
Data Science is an integrative field that employs scientific methods, algorithms, procedures, and systems to extract insights and knowledge from both structured and unstructured information. It combines elements from various disciplines, such as statistics, mathematics, computer science, and domain-specific knowledge, to analyze and interpret complex data sets.Â
Data Science is a combination of Data Collection, Data Cleaning and processing, Statistical Analysis, Machine Learning, Data Visualization, and Big Data Technologies.
Types of Artificial IntelligenceÂ
Artificial intelligence is divided into two broad categories, which are:
1. Narrow Artificial Intelligence
Narrow Artificial Intelligence refers to AI systems that are created and trained for a single task or a limited collection of tasks. These are also referred to as Weak Artificial intelligence. These systems are focused on performing a single task or solving a particular problem and cannot generalise beyond their predefined scope.Â
Examples of narrow artificial intelligence include virtual assistants like Siri and Alexa, autonomous vehicles, and recommendation systems like those used by Amazon or Netflix.Â
Narrow artificial intelligence has seen significant advancements and widespread adoption across various industries due to its ability to automate specific tasks, improve efficiency, and enhance decision-making. However, these systems are limited to their specific domains and lack the broader understanding and adaptability characteristic of human intelligence, or artificial general intelligence (AGI).
2. General Artificial Intelligence
General Artificial Intelligence refers to AI systems that possess the ability to understand, learn, and apply knowledge across a wide range of tasks, similar to human intelligence. These are also referred to as Strong Artificial Intelligence or Artificial General Intelligence. General artificial intelligence would be capable of reasoning, learning, problem-solving, and adapting to various situations without human intervention.Â
Artificial General Intelligence is a long-term goal of AI research and remains a subject of ongoing scientific inquiry and speculation. Whole Narrow AI has achieved remarkable progress in specialized domains, General AI requires a deeper understanding of human cognition, advanced learning algorithms, robust reasoning mechanisms, and the ability to integrate knowledge from diverse sources.

Life Cycle of Data ScienceÂ
The data science life cycle refers to the process of solving real-world problems using data-driven approaches. A typical data science life cycle consists of several interconnected steps:Â
- Problem Identification: Identify and define the business problem or opportunity that data science can address. The objective and desired outcomes of the data science project must be clearly articulated.
- Data Collection: Gathering relevant data from different sources, including databases, APIs, files, sensors, or external vendors. Data quality, completeness, and consistency must be ensured through data cleaning and preprocessing.
- Exploratory Data Analysis (EDA): Exploration and visualization of the data to gain insights into its structure, patterns, distributions, and relationships. Verifying and identifying potential issues, trends, or anomalies in the data that may influence subsequent analysis.
- Model development: Select appropriate machine learning algorithms or statistical models based on the problem requirements and data characteristics. It involves training the models using labeled data or allowing them to learn patterns from the data. Optimizing model parameters and hyperparameters to improve performance and generalization.Â
- Model Evaluation: Assess the performance of the trained models using evaluation metrics relevant to the problem. Validate the models using techniques such as cross-validation to ensure robustness and generalization.
Model Deployment: Integrate the trained models into operational systems or decision-making processes to generate predictions or recommendations in real-time. Monitor model performance and behavior in production to detect drift, degradation, or biases.
Role of Artificial Intelligence in Data Science
Artificial Intelligence (AI) plays a significant role in various stages of the data science life cycle, enhancing the capabilities of data scientists and enabling them to extract actionable insights from data more effectively. Some key roles of AI in data science include:Â
