 ### What your learning application must do:
 
-1. Your application must be able read a comma separated file as training data with the following columns: 
+1. Your application must be able read provided comma separated files. 
 
 2. Similarly, your application must accept a separate comma separated file as validation data with the same format.
 3. You can make the following assumptions:
- 1. Columns will always be in that order.
- 2. There will always be data in each column.
- 3. There will always be a header line.

 An example input files named `training_data_example.csv`, `validation_data_example.csv` and `employee.csv` are included in this repo.  A sample code `file_parser.py` is provided in Python to help get you started with loading all the files.  You are welcome to use if you like.
 
 1. Your application must parse the given files.
 2. Your application should train only on the training data but report on its performance for both data sets.
-3. You are free to define appropriate performance metrics, in additional to anyones predefined, that fit the problem and chosen algorithm.

 4. You are welcome to answer one or more of the following questions.  Also, you are free to drill down further on any of these questions by providing additional insights.
 
 Your application should be easy to run, and should run on either Linux or Mac OS X.  It should not require any non open-source software.

 ### Questions to answer:
 1. Train a learning model that assigns each expense transaction to one of the set of predefined categories and evaluate it against the validation data provided.  The set of categories are those found in the "category" column in the training data. Report on accuracy and at least one other performance metric.
 2. Mixing of personal and business expenses is a common problem for small business.  Create an algorithm that can separate any potential personal expenses in the training data.  Labels of personal and business expenses were deliberately not given as this is often the case in our system.  There is no right answer so it is important you provide any assumptions you have made.
-3. (Bonus) Train your learning algorithm for one of the above questions in a distributed fashion, such as using Spark.  Here, you can assuming either the data or the model is too large/efficient to be process in a single computer.
