Project Introduction
This project that utilizes Selenium and Machine Learning to get good candidate web pages and classify webpages as a demo day page containing a list of cohort companies, currently using scikit learn's random forest model and a bag of words approach

Development Notes
Right now I am working on two different classifier: Kyran's old Random Forest model - optimizing it by tweaking parameters and different combination of features - and my RNN text classifier.
The RF model has a ~92% accuracy on the training data and ~70% accuracy on the test data.
The RNN currently has a ~50% accuracy on both train and est data, which is rather concerning.
Test : train ration is 1:3 (25/75)
Both model is currently using the Bag-of-word approach to preprocess data, but I will try to use Yang's code in the industry classifier to preprocess using word2vec. I'm not familiar with this approach, but I will try to learn this.
The Crawler Functionality
To be updated
The Classifier
Input (Features)
The input (features) right now is the frequency of X_NUMBER of words appearing in each documents. The word choice is hand selected. This is the naive bag-of-word approach.
Idea: Create a matrix with the first col being the file BiBTex, and the following columns are the words, and the value at (file, word) is the frequency of that word in the file. Then, split the matrix into an array of row vectors, and each vector is then feed into the RNN)
This seems to not give really high accuracy with our LSTM RNN, so I will consider a word2vec approach
