One last comment: I though about improving performance (apparently the only thing on my mind during this little project) by doing the whole thing at a lower resolution and then recreating it at a higher one. LDA is particularly useful for finding reasonably accurate mixtures of topics within a given document set. Machine Learning in Action is a clearly written tutorial for developers. Therefore it works best for quickly iterating on rule training and visualization with low-medium sized datasets. By assigning values to the parameters support and confident, and set minlen to prune the rules of 1 item, the apriori function returns all the rules having at least 2 items which exceeds the confident threshold. DataFrames allow you to store and manipulate tabular data in rows of observations and columns of variables. Release your projects faster by plugging-in one of our reusable code snippets.
