DATA1002: Informatics: Data and Computation

DATA1002: Informatics: Data and Computation

Semester 2, 2023 [Normal day] - Camperdown/Darlington, Sydney

Overview

This unit covers computation and data handling, integrating sophisticated use of existing productivity software, e.g. spreadsheets, with the development of custom software using the general-purpose Python language. It will focus on skills directly applicable to data-driven decision-making. Students will see examples from many domains, and be able to write code to automate the common processes of data science, such as data ingestion, format conversion, cleaning, summarization, creation and application of a predictive model.

Assessment summary

  • Weekly coding tasks: Tasks where the student must write a Python program to produce precisely described output. The program will be run automatically against test cases. Grade is based on participation. These are started in tutorial, and completed in students’ own time. Late work is not accepted for these assessments. When special consideration is approved for a task, the appropriate consideration should be “mark adjustment” based on estimating a grade using the average from other tasks or the final exam.
  • Weekly quizzes: Each quiz consists of multiple-choice questions related to the lecture, lab, or tutorial content from the previous week. Done in students own time. Late work is not accepted for these assessments. When special consideration is approved for a task, the appropriate consideration should be “mark adjustment” based on estimating a grade using the average from other tasks or the final exam.
  • Practice Python coding test A: Done in student’s own time. There are 5 separate tasks; for each, the student must extend a Python code skeleton so that it calculates precisely described output from data in a file. Each task is graded automatically, by comparing the output produced on several different inputs to what is described. This carries no weight in final grade, but is intended to accustom students to the setting in preparation for the later coding test, and to trigger remedial learning for any student who does not succeed in the practice. Late work is not accepted for this assessment. When special consideration is approved, the appropriate consideration should be “No action”.
  • Practice Python coding test B: Done in student’s own time. The student must produce Python code that calculates precisely described output from data in a file. This assessment is graded automatically, by comparing the output produced on several different inputs to what is described. This carries no weight in final grade, but is intended to accustom students to the setting in preparation for the later coding test, and to trigger remedial learning for any student who does not succeed in the practice. Late work is not accepted for this assessment. When special consideration is approved, the appropriate consideration should be “No action”.
  • Python coding test A: Held during a scheduled lecture timeslot, or an alternative scheuled timeslot (for cases of special consideration, or where the lecture timeslot is unsuitable). There are 5 separate tasks; for each, the student must extend a Python code skeleton so that it calculates precisely described output from data in a file. Each task is graded automatically, by comparing the output produced on several different inputs to what is described. Late work is not accepted for this assessment. When special consideration is approved, the appropriate consideration should be “New or varied assessment”.
  • Python coding test B: Held during a scheduled lecture timeslot, or an alternative scheuled timeslot (for cases of special consideration, or where the lecture timeslot is unsuitable). The student must produce Python code that calculates precisely described output from data in a file. This assessment is graded automatically, by comparing the output produced on several different inputs to what is described. Late work is not accepted for this assessment. When special consideration is approved, the appropriate consideration should be “New or varied assessment”.
  • Project Stage 1: This is the first part of a group project (the students in a group must all be attending the same scheduled lab session). This stage involves finding data from a domain of interest for the students, data cleaning and importing to a tool, and doing a very simple analysis from some of the data. A report is required that describes the dataset (including the metadata associated to it), how it was obtained, and how it was processed by the tool. If this stage is missed or badly done, the group can be given a clean data set, for a domain chosen by the instructor, to use in the rest of the project. It is crucial that each group manages its internal working effectively, and use mechanisms to detect problems and report them to the coordinator early. When special consideration is approved, the appropriate consideration should be “extension of time”.
  • Project Stage 2: The group will use computational tools to explore the data, and report on both what was done and what was found (using appropriate summaries and charts). It is crucial that each group manages its internal working effectively, and use mechanisms to detect problems and report them to the coordinator early. When special consideration is approved, the appropriate consideration should be “extension of time”.
  • Project Stage 3: The group will use computational tools to produce a predictive model for some aspect of the data, and evaluate this model; deliverable is a report on both what was done and what was found. It is crucial that each group manages its internal working effectively, and use mechanisms to detect problems and report them to the coordinator early. When special consideration is approved, the appropriate consideration should be “extension of time”.
  • Exam: An online exam, with multiple-choice, short-answer, longer (eg half-page) discussions. Covering knowlede, conceptual content, skills, and experiences. Late work is not accepted for this assessment. When special consideration is approved, the appropriate action should be “replacement exam”.

Detailed information for each assessment can be found on Canvas.

Minimum requirement: It is a policy of the School of Computer Science that in order to pass this unit, a student must achieve at least 40% in the written examination. For subjects without a final exam, the 40% minimum requirement applies to the corresponding major assessment component specified by the lecturer. A student must also achieve an overall final mark of 50 or more. Any student not meeting these requirements may be given a maximum final mark of no more than 45 regardless of their average.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

Late work is not accepted for the following assessments: Weekly coding tasks, Weekly quizzes, Python coding test A, Python coding test B, final exam, and for all the unweighted formative assessments (practice assessments). Late work is accepted up till 10 days late, subject to the standard penalties (subtract 5% of maximum possible mark, per day late) for Project stage 1, Project stage 2, Project stage 3. However, note that work submitted late may not receive feedback before the next stage is due.

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Learning support

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Attendance and class requirements

Laboratories: attendance at lab sessions is crucial, as this is where groups are formed, work together, and get feedback on the project stages.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Required readings

These books are optional extra reading; they can be accessed through the Library eReserve, available on Canvas.

  • J. Grus, Data Science from Scratch 2nd ed. O`Reilly, 2019. isbn 1492041130.

Learning outcomes

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University’s graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. automate a computational process, when given a clear account of the algorithm to be applied (to be done by writing Python programs with core techniques of procedural programming)
  • LO2. demonstrate knowledge of Python syntax and semantics, to trace and understand idiomatic code typical of data science activities, including features such as user-defined functions, exception-raising, and handling
  • LO3. understand automation of the computational process needed for examples of the various activity in the data science pipeline: data ingestion and cleaning, data format conversion, data summarization, visual and tabular presentation of the results from summarization, creation of a predictive model of a given form, application of a predictive model to new data, evaluation of a predictive model (and also, automation of a pipeline that scripts use of existing tools for these activities)
  • LO4. understand both spreadsheets, and programs in Python, for automatically performing computational processes of data science, and awareness of the similarities and differences between tools
  • LO5. understand main issues for data management in connection with data science activities, including value of data, importance of metadata, and issues when sharing data across time and users
  • LO6. understand how data sets are represented in computer files, in particular, the many-to-many relationship between the physical representation and the logical representation; advantages and disadvantages of different representations
  • LO7. understand principles of charting and information presentation, and ability to produce good charts using both Python libraries and spreadsheets; also capability to evaluate charts for effectiveness in communication.
  • LO8. understand principles of machine learning and its role in data science, in particular creation, use, and limitations of predictive models for regression and classification tasks, issues of over-fitting and under-fitting, and evaluation of models.

Responding to student feedback

This section outlines changes made to this unit following staff and student reviews.

Unit has been adjusted following feedback from last year survey. I will walk through in more details of the flip-learning and will redesign the Canvas site to give students better idea on how to proceed with the course.
