Study Notes
- Effective communication within data science and machine learning is crucial
Importance of Communication
- Communication skills relate to job performance and is valid in industry and in academic settings.
- Your perceived value by an organization depends on communication.
- It is important to create a portfolio of analyses and products to showcase your expertise.
Why Communication Is Challenging
- Stakeholders often have varied expertise levels.
- Conflicting priorities or goals may exist among stakeholders.
- Stakeholders often have limited time to absorb detailed data analysis.
- Audiences may lack comfort interpreting complex datasets or visualizations.
Stakeholder Identification
- Primary stakeholders are directly impacted by your analysis
- Examples of primary stakeholders includes customers, internal teams, or decision-makers.
- Secondary stakeholders have less direct interest but are still impacted
- Examples of secondary stakeholders includes regulators, investors, or the community where your project has an impact.
- Non-obvious stakeholders may be less visible but still affected e.g., customer service teams when analyzing customer data.
- The stakeholder landscape evolves, requiring regular reassessment.
Managing Stakeholders
- Establish proactive communication to build relationships.
- Understand stakeholder priorities, concerns, and goals that data analysis can address.
- Adjust the detail level of reporting to match the needs of certain stakeholders.
- Involve stakeholders early to gather input and improve the data science process.
- You should be transparent about timelines, data limitations, and insight scope when managing expectations.
Domain Expertise
- Speaking the language of stakeholders requires domain expertise
- Domain expertise allows focuses on framing how project results solve the problems and opportunities
- Domain expertise helps build credibility and trust, thus making analysis more impactful.
- Asking informed questions comes from domain expertise.
Adapting to Stakeholders
- Communicating requires tailoring language at multiple levels
- This includes relevant vocabulary for specific stakeholders (technical vs. jargon).
- Considerations should be made whether to speak briefly or at length to the recipient of the information
- Adjust the level of explanation and facts based on the audience's familiarity with the data.
Common Forms of Communication
- Data science spans academia and industry, and central to both is communication.
- Common forms includes academic research papers, posters, executive summaries, and dashboards.
Academic Papers
- Academic papers aim to deliver information and have a structure of introduction, methods, results, and discussion
- IMRaD is an efficient method of structuring, but can stray from it to make the writing more exciting
Key areas for scientific papers
- Introduction is for setting up the problem, explaining the topic, and giving solution
- Methods explains a solution and how to evaluate it
- Results shows the results of an evaluation
- Discussion focuses on impact related to results
V Structure
- Introduction to introduce the problem and extract research questions
- Methods explains and evaluates a proposed solution.
- Results presents the findings and contextualizes these findings.
- Conclusion summarizes research questions and results; future applications can also be presented here
Paper Structure: Zooming In
- Level 1 headings should contain contain major sections, like the methods, results, etc.
- Level 2 headings should identify themes (e.g., Methods > Evaluation)
- Level 3 Headings contain topics (Methods > Evaluation > Evaluation Metrics.)
- Paragraphs should contain ideas (Methods > Evaluation > Metric > F1-Score)
Paragraph Construction
- Each paragraph should consist of:
- An introductory sentence setting the stage.
- A main body to elaborate on key points.
- A closing sentence to provides closure or transition
Academic Posters
- Academic posters are graphical, per-reviewed, and meant to inform within academic settings.
- The posters are non-linear, meant to explain a speaker with many plots present.
Executive Summaries
- These summaries should act as a single page linked to a technical report
- The target should be executives and decision makers, meant to assist in the decision making process.
- Key elements are problem statements, methodologies, key findings, recommendations, and visualizations.
Dashboards
- Interactive dashboards allow exploration of data analysis.
- These are often informed from live data and should assist with decision making.
- They often center around key performance indicators (KPIs) and metrics.
Dashboard Design Principles
- Dashboards should have an intuitive layout for immediate user understanding.
- Visual emphasis should be given to impactful data using appropriate charts.
- Interactivity should be supported.
- Dashboards should be clean and uncluttered.
Active vs Passive Dashboards
- Active dashboards allow to interact with and act upon the data, whereas passive are read only.
- Human involvement becomes important for active dashboards due to data, removing of observations and labelling
The Need for Human-in-the-Loop AI
- Various approaches exist, including interactive sense-making, explainable AI, adversarial training with human involvement, active learning, and meta-learning.
- There is an emphasis on full automation in AI and machine learning with large datasets and models.
- This process lends itself better to benchmark marking and specialization.
- Retaining humans in the process of improving beyond limitations, improving context
Active Learning
- Traditional supervised learning relies on randomly sampled and labeled training examples.
- Active learning enables algorithms to start with limited amount of labeled or unlabeled data.
General Active Learning
- A new batch of data points are selected based on specific criteria.
- You query human user to label that batch and retrain the model for the next batch.
Common Query Models
- Uncertainty sampling: Labelling is least certain among all instances; classifiers find documents closest to random chance
- Query by committee involves training multiple models, disagreeing on labelling based on votes and sends to user
- Expected outcomes involves documents where knowing would produce an estimate on the generalisation error.
Reasons to prefer active learning over supervised learning:
- Active learning allows for continuous labeling and allows to adapt to shifts in data.
- Active learning is cost effective.
- Quality is preferred over quantity.
Data Storytelling
- Data storytelling connects facts, transforming the analysis into a memorable narrative
- It uses a compelling question, builds tension, resolves with impacts, and utilizes visuals
Storytelling Frameworks
- A.I.D.A. captures attention, presents interest, shows how positive outcomes happen, and calls to action with information
- 5W is about using the structure to write a complete and through summary
- S.C.Q.A. defines a situation, followed with a complication, then a question, and the answering with the data given
- A Pyramid Structure gives conclusion first, followed with arguments and background data
Presenting an Analysis
- Presentations should begin with relevant hooks
- Focus on 2-3 major findings.
- Give recommendations with actionable steps
- Reiterate the importance of the work
Presentations
- Explain why results matter, and use impactful charts.
- Practice presenting, and anticipate questions.
Communication: BLUF
- BLUF communicates the bottom line up front early, sets clear expectations, and starts with the key conclusion.
Communication: Being Clear and Concise
- Cut unnecessary jargon and tangential details
- In a paper/dissertation use the active voice rather than passive, avoid subjective language, and be precise.
Communication: Visuals
- Utilize charts, as often visual are most memorable when comparing to text alone
- Common graphs are stacked bar charts, scatter plots, and line graph.
Communication: Abstracts
- Short versions of a paper, the abstract includes objectives to the work, ideas of methods used, results and important outcomes.
- Abstracts should aim to capture the reader
Communication: Audience
- Scientific papers should be adapted to relevant audience, discover/use vocabulary, and conventions as well should be used.
Communication: Formatting
- Figures should be correctly labeled
- Choose the right figure and be careful to avoid "chart junk"
Ethics
- The main ethical aspect should be focused on plagiarism prevention
- Data should not be manipulated
- Cherry picking and random seed optimisation is to be avoided
- It all comes down presenting work in a way where the audience understands
