    Study Notes

    Contemporary Data Practices

    • Contemporary data practices leverage data to build systems that make decisions without human intervention
    • Key goals of contemporary data practices include understanding Artificial Intelligence (AI), the Turing test, neural network modelling, expert systems, and the use of data for analysis.

    Learning Objectives

    • Understand the definition of Artificial Intelligence (AI)
    • Understand the significance of the Turing Test
    • Understand the main features of neural network modeling
    • Understand the structure of an expert system and its components
    • Understand the use of data in analysis

    Starter

    • What is AI?

    Artificial Intelligence

    • AI simulates intelligent behavior in computers, enabling machines to make informed decisions without human intervention.
    • Artificial Narrow Intelligence (ANI), also known as weak AI, is designed for a specific task and has limitations in other situations.
    • Artificial General Intelligence (AGI) is a highly advanced form of AI that mimics human thought and reasoning in various contexts.

    Machine Learning

    • Machine Learning is a subset of AI that utilizes algorithms to adapt and improve from experience without explicit programming.
    • Machine Learning relies on training data from large datasets to train the algorithms.

    The Turing Test

    • The Turing Test, developed by Alan Turing, is a benchmark for assessing machine intelligence.
    • It involves a human evaluator engaging in text-based conversations with both a human and a machine.
    • The evaluator must determine which participant is the human based on the conversation.
    • If the evaluator isn't able to correctly determine if the participant is a machine, then the machine is deemed to have passed the test.

    Neural Networks

    • Neural networks attempt to solve complex problems often resembling the structure of a human brain.
    • Neural networks consist of interconnected nodes (neurons) with layered structures.
    • Information is processed and transmitted in a layered fashion.
    • Neural networks learn and adapt from their experiences through algorithms, adjustments, and training.
    • Different types of neural networks exist like feed-forward, recurrent, convolutional, deconvolutional, and modular neural networks.
    • Neural networks are used in applications like computer vision (facial recognition), speech recognition, natural language processing, and recommendation systems.

    Expert Systems

    • Expert systems are AI systems that replicate the decision-making capabilities of human experts.
    • Important components involved in Expert Systems include the knowledge base, the knowledge acquisition system, expert interface and user interface, knowledge engineer, inference engine, explanatory system, working memory, shell, and heuristics.
    • Expert systems use fuzzy logic to handle uncertainty and imprecision in knowledge, which makes them more suitable for real-world applications where information is not always clear-cut.

    AI Usage of Big Data

    • AI technologies, such as machine learning, rely on large datasets to make decisions and predictions.
    • Al systems collect data from various sources like sensors, internet, and user interactions.
    • Data needs processing to make it suitable for analysis which may involve removing outliers, handling missing values, and restructuring the data. Data analysis in AI involves multiple types including descriptive, diagnostic, predictive, and prescriptive.

    Ethical Considerations in AI

    • Data bias and algorithmic bias are significant factors.
    • Systems are trained using data that can reflect prejudices leading to unfair outcomes.
    • AI systems can raise privacy concerns and questions regarding access and legality and potential impact on employment.
    • Understanding and mitigating these issues are key ethical considerations for AI.

    Social Considerations in AI

    • AI systems have several positive and negative implications on society.
    • Use of AI and large data sets raise issues like disenfranchisement, discrimination, removal of ethical considerations, privacy concerns, and large scale unemployment.
    • How bias can exist in data and implications on decision making are also important to consider.

    Data Analytics

    • Data analytics is the computational analysis of data to uncover trends and insights.
    • Different types of data analysis (Descriptive, Diagnostic, Predictive, and Prescriptive) are used for various purposes.
    • Data analysis methods are integral to decision-making.

    Data Flow Diagrams

    • Data flow diagrams are graphical representations that show how data flows through a system.
    • They identify the origin, storage, and final destination of data through processes, which help with clear representations and understanding.
    • Several key parts, such as external entities, data stores for storage, processes, and data flows, are fundamental in constructing a diagram to depict the data flows.
