Key Steps to Complete the Task
- Feature Identification: Brainstorm and identify potential features from the data explored in Week 1 that could prove predictive and meaningful.
- Engineering: Explain how raw data may be transformed (e.g., normalization, encoding) into useful features, including any considerations for dimensionality reduction.
- Model Selection: Evaluate different machine learning model families, such as regression vs. classification models, and justify your choice based on application context.
- Documentation: Provide a structured narrative in your DOC file that clearly details every step of your reasoning process.
Evaluation Criteria
The submission will be assessed on your clarity of thought in feature transformation, logical reasoning in model selection, thoroughness in comparative analysis, and the overall coherence of the document. The task is designed to be completed in about 30 to 35 hours. Your final DOC file should reflect a deep understanding of the relationship between data features and model performance in real-world scenarios.
Task Objective
This task requires you to implement a machine learning model tailored to a scenario in the apparel and textiles industry using publicly available data insights from earlier weeks. The goal is to build a prototype that demonstrates the practical application of your selected algorithms. Emphasis should be placed on explaining your implementation process and assumptions, ensuring that the final document stands alone for a technical audience.
Expected Deliverables
- A DOC file detailing the entire implementation process.
- Sections covering code explanation, algorithm selection rationale, technical challenges, and simulated results or output summaries.
- Flowcharts or pseudo-code segments to illustrate the operational logic of your solution.
Key Steps to Complete the Task
- Algorithm Implementation: Describe the process of coding a prototype model using common programming frameworks. Present an overview of your chosen method (e.g., decision trees, logistic regression, or clustering techniques) and explain its suitability.
- Experimental Setup: Detail your experimental design, how you prepared the data, handled training vs. testing splits, and ensured an unbiased evaluation.
- Documentation of Challenges: Document any issues encountered and solutions or workarounds applied. Highlight assumptions and steps taken to mitigate potential errors.
- Summary of Findings: Provide an analysis of the model's performance, even if using simulated metrics or theoretical outcomes.
Evaluation Criteria
Your DOC file will be evaluated based on the clarity of technical explanations, logical structuring of implementation steps, thorough documentation of challenges, and the overall robustness of your simulated results. The task should require roughly 30 to 35 hours to complete and should display a well-rounded approach to bridging theoretical and practical aspects of machine learning in the context of apparel and textiles.
Task Objective
This week's task centers on evaluating and interpreting the machine learning model developed in the previous week. Your objective is to analyze how well the model performs and to provide strategic insights based on its output. In addition, you must document a comprehensive report that details performance metrics, potential biases, and actionable recommendations for model improvement.
Expected Deliverables
- A detailed DOC file containing the evaluation report.
- Sections should cover performance metrics (accuracy, precision, recall, etc.), diagnostic plots, and interpretations of the model’s behavior.
- A section dedicated to discussing potential biases and flaws in the model, with suggested strategies to overcome these issues.
Key Steps to Complete the Task
- Performance Analysis: Choose appropriate evaluation metrics that are relevant to the apparel & textiles domain and explain why they were selected.
- Diagnostic Visualizations: Create visual aids that demonstrate the strengths and weaknesses of the model’s predictions, and explain the patterns observed.
- Error Analysis: Conduct a thorough error analysis to identify potential shortcomings, overfitting, or underfitting in the model.
- Recommendations: Based on your analysis, propose actionable recommendations for model fine-tuning or feature adjustments.
- Comprehensive Reporting: Compile your findings, visualizations, and recommendations into a structured DOC file that communicates all key aspects effectively.
Evaluation Criteria
Your evaluation will focus on the thoroughness of the performance discussion, clarity in presenting evaluation metrics and visualizations, depth of error analysis, and the practicality of improvement recommendations. The DOC file should be organized, detailed, and reflective of about 30 to 35 hours of thoughtful work.
Task Objective
The final weekly task encourages you to integrate your learnings from the previous weeks into a strategic planning document that reflects on the overall machine learning pipeline developed for an apparel and textiles scenario. This task is designed to piece together all previous efforts into a cohesive strategy that outlines practical steps for production deployment, iterative improvements, and potential business impact.
Expected Deliverables
- A DOC file that serves as a reflective report and strategic guide.
- The document should include sections on project overview, pipeline summary, strategic insights, and a roadmap for future enhancements.
