Unit rationale, description and aim
Machine learning is the process of teaching a machine to learn from datasets for a variety of tasks. Machine learning models and algorithms are widely used in human’s digital life such as email client, search engine, social media, virtual personal assistant, healthcare and recommendation system. This unit provides a practical and technical introduction to machine learning models and algorithms. Topics to be covered include problems of discovering patterns in the data, classification, regression, feature extraction and data visualisation. Also covered are hands-on implementation and usage of various types of machine learning techniques via Python Scikit-Learn to solve real-world problems such as in digital health. This unit will also consider the issue of machine bias and how it may have an adverse impact on the common good.
Learning outcomes
To successfully complete this unit you will be able to demonstrate you have achieved the learning outcomes (LO) detailed in the below table.
Each outcome is informed by a number of graduate capabilities (GC) to ensure your work in this, and every unit, is part of a larger goal of graduating from ACU with the attributes of insight, empathy, imagination and impact.
Explore the graduate capabilities.
| Learning Outcome Number | Learning Outcome Description | Relevant Graduate Capabilities |
|---|---|---|
| LO1 | Demonstrate comprehensive knowledge of using data science libraries and tools for data processing and analysis | GC1, GC2, GC9, GC10, GC11 |
| LO2 | Appraise the use of fundamental data science and machine learning theories, key techniques and relevant tools for machine learning preparation | GC1, GC2, GC3, GC7, GC10, GC11 |

Learning and teaching strategy and rationale
Multimode
This unit will be delivered in a multimode over a twelve-week semester or equivalent study period. Students will have access to all primary learning materials online through Canvas, along with formative and summative assessments, all of which will be available online, to provide a learning experience beyond the classroom. While there are no formal classroom lectures for this unit, students will be required to attend weekly two-hour workshop and fortnightly one-hour lab for the achievement of the unit learning outcomes. Workshops facilitate learning by theory comprehension and problem solving while lab sessions focus on hands on practices, which in combination is particularly effective for learning information technology skills.
Students should anticipate undertaking 150 hours of study for this unit, including class attendance, readings, online forum participation and assessment preparation.
ACU Online
This unit uses an active learning approach to support students in the exploration of knowledge essential to the discipline. Students are provided with choice and variety in how they learn. Students are encouraged to contribute to asynchronous weekly discussions. Active learning opportunities provide students with opportunities to practice and apply their learning in situations similar to their future professions. Activities encourage students to bring their own examples to demonstrate understanding, application and engage constructively with their peers. Students receive regular and timely feedback on their learning, which includes information on their progress.
Assessment strategy and rationale
A range of assessment procedures will be used to meet the unit learning outcomes and develop graduate attributes consistent with University assessment requirements. The first assessment consists of simple programming tasks to practice data processing, analysis practical and machine learning skills. The purpose is to assess students’ practical skills of using Python data science and machine learning libraries and tools for data processing and analysis. The second assessment is a more specific image data exploration and machine learning preparation task that covers fundamental knowledge of data science and machine learning. The purpose is to assess students’ understanding and skills in data preparation for machine learning preparation. The final assessment is a group project to do experiments with machine learning models and algorithms. The purpose is to assess students’ knowledge and skills of applying key machine learning algorithms to solve real-world problems e.g. in digital health with consideration of machine bias, continuing from the machine learning preparation task. There are fortnightly lab sessions associated with the assessments including assessable lab participation/engagement.
The assessments for this unit are designed to demonstrate the achievement of each learning outcome. To pass this unit, students are required to obtain an overall mark of at least 50%.
Overview of assessments
