Neural network training and execution cycle
Definition
In the training cycle, weightings and threshold values for each node are set by exposing the network to inputs with known responses. In the execution cycle, those learned values are used to produce the output. Stronger weightings mean higher priority.
Example: Training sets the weights; execution uses them.
Found in: course specifications, school notes.

How to use it in an answer
A model sentence
“In the training cycle, weightings and threshold values for each node are set by exposing the network to inputs with known responses.” Then apply it: Training sets the weights; execution uses them.
In a short answer, give the definition in your own words first, then tie it to the situation in the question. Do not copy the example above unless it fits the scenario.
Command words used with it
- Explain: Relate cause and effect; make the relationship between things evident; provide why and/or how. (2025 HSC Q25 (5 marks): Patterns in human behaviour; neural networks (virtual personal assistant))
Technique for the question types
- Short answer: One clear point per mark, use the stimulus and course terms, and answer the command word.
- Multiple choice: Read all four options, rule out wrong ones, pick one; no penalty for guessing so never leave blank.
What the marking guidelines and feedback say
Marker feedback: explain how a neural network interacts with the VPA; differentiate neural networks from AI; use course language (nodes, weightings); pick clear positive and negative impacts from the stimulus.
Worked answers from the marking guidelines
2025 HSC Q25 (5 marks): Patterns in human behaviour; neural networks (virtual personal assistant) (5 marks): criteria and sample answer
Criteria
5: Explains how the neural network supports the VPA AND includes one positive AND one negative impact. 4: Explains how the NN supports the VPA OR outlines how it supports the VPA and includes one positive AND one negative impact. 3: Outlines features of a neural network AND/OR impacts. 2: Outlines a feature of a neural network OR an impact, OR identifies features/impacts. 1: Some relevant information.
Sample answer
Neural networks recognise natural language patterns to categorise common support queries, such as lost luggage, and use nodes to assist with processing. They assess language tone to gauge frustration or urgency, allowing the virtual personal assistant to recommend specific phrasing for customer service staff. For instance, calming language may be suggested for distressed customers. By tracking customer ratings and turnaround times, the neural network uses weightings to refine recommendations to prioritise high-frequency queries or improve suggestions for poorly rated interactions. While this system streamlines support processes and improves response accuracy, it may also impact the role of customer service staff. As the neural network learns from interactions, staff may rely more on its recommendations, potentially reducing their familiarity with emerging query trends or response strategies. Customers may come to expect faster, more precise service, raising the standard for human interactions.
Common mistakes
- Use the term exactly as the syllabus words it, then link it to the scenario in the question; the 2025 feedback repeatedly rewards using the stimulus.
- Answer the command word: outline gives main points only, explain gives a reason or cause, discuss gives both sides.
