     1. Data cleaning
         1. Tokenize text
         2. Clean & normalize tokens: remove stop words, punctuation, make all text lowercase and lemmatize words (extracting base words, e.g., "running" becomes "run")
-    2. Convert text into matrix format: convert preprocessed tokens to a numerical format models can take in using a count vectorizer which takes in n-grams from the corpus and counts the number of instances that n-gram is seen in the example
+    2. Embed text: convert preprocessed tokens to a numerical format models can take in using a count vectorizer which takes in n-grams from the corpus and counts the number of instances that n-gram is seen in the example
 
 2. Build a machine learning pipeline to obtain predictions (each notebook performs requisite text cleaning and preprocessing before applying models)
-    1. Build and tune two models, logistic regression and gradient boosted trees, to predict whether an article is from an unreliable source (fake)

     2. Perform Linear discriminant analysis (LDA) topic modeling to analyze which topics are more likely to be manipulated into fake news.
