Download, prepare, and upload a census income dataset. 2. Create a new Azure Machine Learning experiment. 3. Train and evaluate a prediction model. #The overall workflow of the experiment • Create New blank experiment. Name = Adult Income 1 • Click Data Input and Output • Drag & drop Import Data #Configure Import data module: • Data source = Web URL via HTTP<br> • Data source URL = http://archive.ics.uci.edu/ml/ machine-learning-databases/adult/adult.data • Data format = CSV • Run experiment • Right click at the output of Import Data • Click Visualize • Click on Col2 • Look at Statistics and Histogram #Split up the dataset • Training data This grouping is used for creating our new predictive model based on the inherent patterns found in the historical data via the ML algorithm we use for the solution. • Validation data This grouping is used for testing the new predictive model against known outcomes to determine accuracy and probabilities. #Add Split Data: • Click Data Transformation<br> • Click Sample and Split • Drag & drop Split Data module into canvas • Connect Import Data to Split Data • Set properties Fraction of row to 0.80 • Add Two-Class Boosted Decision Tree and Train Model • Connect Two-Class Boosted Decision Tree to Train Model • Connect Split Data to Train Model • Click Train Model • Click Launch column selector • Include col15 • Click • Save • Run #Score the model: • Add Score Model to canvas • Connect Score Model to Train and Split model • Run #Visualize the model results • Visualize output of Score Model • Scored Labels This column denotes the model’s prediction for this row of the dataset. • Scored Probabilities This column denotes the numerical probability (or the likelihood) of whether the income level for this row exceeds $50,000.   #Type of datasets #Training set • A set of examples used for learning • Where the answer value is known. #Validation set • A set of examples data • Used to tune the architecture of a classifier • And estimate the error #Test set • Use to test the performances of a classifier • Never used during the training process • Give estimate of error **#More Information** #Two-Class Boosted Decision Tree https://msdn.microsoft.com/en-us/library/azure/dn906025.aspx #Score Model https://msdn.microsoft.com/en-us/library/azure/dn905995.aspx <br><br> ---------- > This ML experiment is for [Microsoft Azure Machine Learning Course][101].<br> For the complete experiment list [Click here][102].<br> Laploy | laploy@gmail.com | 084 007 5544 | [www.laploy.com][103]<br> ![enter image description here][104] ---------- [101]: https://notebooks.azure.com/laploy/libraries/loyml/html/00001%20Sessions%20summary.ipynb [102]: https://gallery.cortanaintelligence.com/Home/Author?authorId=81E333F747E3429B55A3445E6714C36F60B397C13B4D0B07F34DEF1421F64D73 [103]: http://laploy.com [104]: https://raw.githubusercontent.com/laploy/mli/master//loy-small.jpg [11]: https://raw.githubusercontent.com/laploy/mli/master//loy-small.jpg
