  • HomeWork1:
    (0) How do you collect your own data (Friends)? (FB, Google, IG, Line?)
    =>(At least 100 records=> 5-fold, You have to make As robust as Possible)
    => Is your dataset Robust enough?
    What characteristis (features),
    Nation(Country),
    sex (M or F),
    Zodiac Signs (Star Signs)"
    "Blood Type"(A,B,AB,O)
    Personal Favors(Spicy? Colors? ...)

  • Chapter 6: Learning Best Practices for Model Evaluation and Hyperparameter Tuning
  • Middle Project (40%)
    (1) you choose for predicting "Zodiac Signs (Star Signs)" and "Blood Type"
    (2) Classifying with your own data (CV K-fold?)(Confution Matrix, Accuracy, F-Measure)
    (3) From your own experimental results, can we pridict the "Zodiac Signs (Star Signs)" or "Blood Type" of some ones
    (4) What are your points to improve your experimental results if possible

    　Top 10 CancerTypes in PubMed

    PubMed_Cancer_jdwang2021_9_28.7z
    Topic : Text Classification of Cancers via Medical Articeles in PubMed Corpus
    The types of Cancer(Choose five types at least)
    Resource : PubMed
    (Download PedMed Articles via PubMed API
    (Download PedMed Articles via Download MEDLINE/PubMed Data
    Try to train and construct a classifier for determining the class ("cancer type") of PubMed articles
    (Python Package : NLTK Natural Language ToolKit)
    (bag-of-words)
    Term-Frequency (TF)
    Inverse-Document-Frequency (IDF)
    Term Weighting : TF*IDF
    stop-word removal
    Word stemming : Porter stemming algorithm
    Single-class Classification (Sentiment Analysis (positive or negative)) vs. Multi-classes Classification (Which type of cancers is ?)
    Computation Power limitation : Out-of-core learning

    As in Chapter 9, construct a Web interace for user to upload one PubMed articels and then to determine the cancer types of that PubMed article via above trained classifier.
