Evaluation Criteria
Your plan will be assessed on its clarity, depth of analysis, and the feasibility of the proposed implementation roadmap. Consistency, detail-oriented planning, and effective use of NLP theory in a practical context are key factors in evaluation. This task timeline is designed to demand 30 to 35 hours of focused work, bridging theoretical understanding and potential practical implementation.
Objective
This week, your focus is on devising a comprehensive strategy for data preprocessing and feature engineering as applied to NLP projects. The objective is to demonstrate your understanding of how raw text can be transformed into structured inputs for modeling by incorporating techniques such as tokenization, normalization, and vectorization.
Expected Deliverables
Produce a DOC file detailing a step-by-step data preprocessing and feature engineering strategy. The document should include sequential sections describing each step, potential challenges, and creative solutions for handling diverse textual data.
Key Steps
- Introduction to Data Preprocessing: Provide an overview of the importance of preprocessing in NLP.
- Detailing Techniques: Discuss techniques like tokenization, stemming, lemmatization, and handling stop words with clear examples drawn from publicly available sources.
- Feature Engineering: Explore methods for feature extraction such as TF-IDF, word embeddings, and other vectorization techniques. Explain how these methods add value to the modeling process.
- Challenges and Solutions: Identify potential issues such as data imbalance or noise in textual data and propose strategies to mitigate these issues.
- Documentation and Presentation: Ensure your final plan is well-organized and easy to follow.
Evaluation Criteria
Submissions will be evaluated on clarity, structure, depth of technical detail, and the logical flow of data processing ideas. The quality of your DOC file presentation and the comprehensiveness of your strategies are crucial to the review process. This task is intended to be completed in 30 to 35 hours, emphasizing detailed planning and innovative thinking within the realm of NLP data preparation.
Objective
This week’s task focuses on designing a thorough framework for the evaluation of NLP models. You will research and articulate the best evaluation metrics for a chosen NLP application, then propose a method to analyze model performance based on these metrics.
Expected Deliverables
Submit a DOC file that contains an exhaustive evaluation plan. This document should cover the selection rationale for specific metrics, a detailed analysis plan, and recommendations for subsequent steps based on performance outcomes.
Key Steps
- Selecting the Application and Model: Choose an NLP application, such as chatbots, translation, or sentiment analysis, and identify an appropriate evaluation strategy.
- Literature Review: Investigate existing research and techniques regarding evaluation metrics in NLP. Summarize findings in your DOC file.
- Designing Evaluation Metrics: Clearly explain metrics such as accuracy, precision, recall, F1 score, BLEU score, or others depending on your model’s needs.
- Performance Analysis: Develop detailed methods for analyzing model output quality and performance trends over time.
- Actionable Recommendations: Provide a section that explains how these evaluations would guide improvements in the model and project strategy.
Evaluation Criteria
Your submission will be assessed based on the relevance and depth of your evaluation and performance analysis framework, clarity in reasoning, and thoroughness in proposing actionable recommendations.
