How to use

• Get word list (best to use domain-specific words to lower the computational costs)
• Train the Model (check out example-train.py)
• Specify the path to save the model to reuse afterward.
• Load the Model and correct the words (check out example.py)

How the model works (high level)

• Preprocess the dictionary removing accentuation and transform to lowercase
• Extract char n_grams from the dictionary
• Create a sparse matrix from the dictionary utilizing the Bag of Words strategy
• Create a sparse matrix from the word preprocessed
• Compare the two sparse matrices by cosine similarity
• Return the most similar word
