Notes on Artificial Intelligence Lecture

Definition of Artificial Intelligence

  • AI is defined as a machine that can sense, reason, act, and adapt.
  • Data is fundamental: collecting, storing, accessing, and labeling data.

Engaging with Business Executives

  • If given a chance to meet top business executives (e.g., Steve Jobs, Bill Gates), the key question would be:
    • "How would you tackle my current business challenge?"
  • Access to their insights is analogous to having a hard disk full of historical data.
  • Knowing your goals is crucial for extracting valuable insights.

Importance of Data

  • Owning data is just the beginning; knowing what's in the data is essential.
  • There are nontrivial challenges in transforming owned data into actionable knowledge.

The Four Vs of Big Data

  1. Volume:
    • Challenges in storing data, updating information, querying, and backing up data.
  2. Velocity:
    • Rate at which new data is generated (e.g., from sensors, programs).
    • Need for an efficient injection of new data into pipelines.
  3. Variety:
    • Different sources of data that need to be integrated into AI systems.
  4. Veracity:
    • Reliability of incoming data; issues with faulty sensors producing unreliable data.

Labeling Data

  • Essential for supervised learning.
  • A label indicates the category or class of each data point.
  • The labeling process can often be manual unless automated methods exist.
  • Approximately 50% of the time in a project may be spent on data preparation and labeling.

Data Formats

  • Four main categories of data formats:
    1. Images
    2. Time series (audio, forecasts)
    3. Text (documents, social media posts)
    4. Tabular (spreadsheets, tables)
  • Knowledge of these categories aids in data handling and solution development.

Reusability of AI Solutions

  • Solutions developed for one category can often be adapted for another industry (e.g., using retail image recognition technology in airport luggage identification).
  • Recognizing this potential can enhance efficiency in problem-solving across different sectors.

Conclusion

  • Understanding AI, data handling, and the nature of business challenges are vital for leveraging technology successfully.
  • Encouragement to join the next section on machine learning and AI.
