Defining Data Science

  • Data science is still evolving as a well-defined field.
  • There isn't a standard, universally accepted collection of knowledge.
  • Significant overlap exists with other disciplines.
  • The field is subject to hype and exaggeration.
  • A central authority to correct misinformation is lacking.
  • This ambiguity makes curriculum development challenging.

Learning Data Science

  • Some industry professionals argue that data science is best learned on the job, rather than in academic settings or through books.
  • However, the lecturer believes that there are fundamental principles that can be taught.

The Art of Data Science

  • Many practitioners jump directly to complex algorithms.
  • However, there are crucial steps and considerations before that.
  • One vital aspect is the infrastructure required to support these algorithms.
  • Functionality can be broken down into three areas:
    • Data management
    • Data processing
    • Resource management

Industry Insights from ZHAW Survey (2022)

  • Survey by Mildenberger & Stockinger at ZHAW in 2022 revealed:
    • Machine learning is gaining traction in industry.
    • Data engineering skills, particularly in data management (e.g., SQL & DWH), are highly sought after.

A Word of Warning: Potential Pitfalls

  • Data science systems can handle vast amounts of data, enabling analysis and model building.
  • However, these models can inadvertently encode prejudices, misunderstandings, and biases.
  • Increasingly, these models govern aspects of our lives.

Addressing the Pitfalls

  • Cathy O’Neil refers to problematic models as “Weapons of Math Destruction.”
  • The systems and data aren't going away.
  • Actions to mitigate the negative impacts:
    • Increase transparency
    • Implement checks and balances
    • Ensure accountability for responsible parties
