Create your own ChatGPT with Retrieval-Augmented-Generation workshop
Marketing Data Science is a first of a series of courses on Business Data Science. The course was constructed to be a meeting point between Marketing and Data Science. A marketing framework analysis is proposed composed of four blocs: Profiling, Segmentation, Targeting and Recommendation. For each of these blocs a Data Science analysis is applied. The pivoting question is: How to better understand your customer. Throughout the course we will use a single database to apply the different concepts and Data Science techniques. Three tools will be presented and used: SQL, Power BI and Microsoft Azure ML If you are a marketer who want to be introduced to the Data-Driven analysis field, then this course is for you. If you have a technical background (IT professional, Developer) and you inspire to become a Data Scientist, then you can take advantage of the Marketing Framework Analysis to introduce you to the business skills a has to know.
Summary In this article, we are going to present the solution for the Women’s Health Risk Assessment data science competition on Microsoft’s Cortana Intelligence platform which was ranked among the top 5%. In this page, you can find the published Azure ML Studio experiment., a description of the data science process used, and finally a link to the R code (in GitHub). Competition Here is the description from the Microsoft Cortana Competition “To help achieve the goal of improving women's reproductive health outcomes in underdeveloped regions, this competition calls for optimized machine learning solutions so that a patient can be accurately categorized into different health risk segments and subgroups. Based on the categories that a patient falls in, healthcare providers can offer an appropriate education and training program to patients. Such customized programs have a better chance to help reduce the reproductive health risk of patients. This dataset used in this competition was collected via survey in 2015 as part of a Bill & Melinda Gates Foundation funded project exploring the wants, needs, and behaviors of women and girls with regards to their sexual and reproductive health in nine geographies. The objective of this machine learning competition is to build machine learning models to assign a young woman subject (15-30 years old) in one of the 9 underdeveloped regions into a risk segment, and a subgroup within the segment.” https://gallery.cortanaintelligence.com/Competition/Womens-Health-Risk-Assessment-1 Dataset The contains 9000 observations The original training dataset is in CSV format and can be found in the competition’s description. To submit a solution, two options are possible: build it in Azure ML Studio or build your solutions locally in R and then submit it through Azure ML Studio. An Azure ML’s solution, and a R script code where given as example. The two solutions are based on the use of a Generalized Linear Model is automatically downloaded. You can find a detailed description of the dataset, the R sample Code and a tutorial using Azure ML and R in the competition page Solution I started following the R tutorial for this competition. Then I have submitted the exact same R solution. The sample model has a 77% accuracy Pre-processing & Cleaning The first thing I did was changing the initial multinomial model (nnet package) for a random forest model (RandomForest package). All missing values have been replaced by 0 Feature selection Features have been selected using the function varImpPlot from the randomforest package Parameter tuning I have chosen (for educational matter) to use the module Tune Model Hyperparameters in Azure ML Studio. I could have also used the R Package Caret. Evaluation The final model has an accuracy of 86.36% (18 position over almost 500 participants) You can download the R code here
