    Study Notes

    Machine Learning Concepts

    • Machine Learning includes Deep Learning, Neural Networks, and more.
    • A heuristic is a strategy or rule of thumb that simplifies problem-solving.
    • Heuristics do not guarantee optimal solutions.
    • Cognitive science encompasses the study of thinking like humans.
    • A model should accurately represent how results were obtained.

    Communication and Programming Languages in AI

    • Communication between humans and machines can involve languages like LISP and ELIZA.
    • ELIZA was created by Joseph Weizenbaum.
    • Prolog is an AI programming language using Predicate calculus.

    Levels of AI

    • The cognition level includes knowledge-based systems and multi-agent systems.
    • AI can be categorized into Narrow AI (task-specific), General AI (human-like intelligence), and Super AI (those surpassing human intelligence).

    Applications and Examples of AI

    • Narrow AI examples: chess-playing programs, e-commerce recommendations, self-driving cars, and image recognition.
    • General AI aims to develop systems that think similarly to humans.

    Digital Evidence and Forensics

    • Digital evidence establishes links between attackers, victims, and crime scenes.
    • The Best Evidence Rule requires digital evidence to meet specific standards.
    • Original media is crucial in digital investigations; reliability of parts of the victim's computer is questionable.
    • Types of digital evidence include digital, demonstrative, explainable, and substantial evidence.

    Handling Digital Evidence

    • Challenges in evidence handling include authentication, chain of custody, and evidence validation.
    • Volatile evidence is crucial to seize quickly due to its temporary nature.
    • Collecting information from networks must adhere to standard operating procedures.

    Forensics Techniques

    • Digital investigators should not turn off computers immediately, as it may affect evidence collection.
    • Forensic images store data from hard drives, including partition tables.
    • Tools like Wireshark can be useful for analyzing network traffic.
    • Chain of custody documents the handling history of evidence, ensuring its integrity.
    • Direct evidence directly establishes facts in court.
    • Evidence can reside in unexpected places like network routers.
    • Expert reports must be supported by multiple independent evidence sources.

    Testimony and Courtroom Protocol

    • Voir dire is the process for experts to be accepted in court.
    • It's essential to maintain honesty during testimonies, with responses like "I don’t know" when applicable.

    Miscellaneous

    • Computer contaminants include malware, while forgery devices may encompass computers and specialized software.
    • The necessity for specialized training emphasizes the importance of proper evidence collection techniques.
