Campaign Success Prediction – End-to-End ML Deployment on GCP Vertex AI

• Business Problem: A marketing agency runs thousands of digital ad campaigns. The business wants to predict whether a campaign will succeed (e.g., meet conversion targets) based on parameters like budget, platform, ad type, CTR, and audience segment.
• Goal: Help campaign managers estimate success upfront — to optimize ad spending and maximize ROI.
• Data Science Framing

• We re-framed this into a binary classification problem
  • Target: Whether a campaign is successful (1) or not (0)
  • Features: Budget, Impressions, CTR, Past Success Rate, Ad Type, Target Age Group, etc

• This is the Gradio based prototype of a smart parking solution Kivy mobile app that we presented in a local hackathon and won second prize. 
• A high quality research backed dataset-considered benchmark in computer vision was used. (Source)
• The prediction model was made using Vision Transformer and it outclassed all other algorithm showing that transformer architecture, which was originally designed for NLP works equally well for image classification.
• Final app had enhanced version of this including object detection, image detection, ability to handle streaming data, QR code based authentication for end users. 

• Stroke is the second largest cause of death, according to WHO. The image shows devastating impact of stroke
• However, stroke can be easily prevented if we can successfully identify at risk patients by easily monitoring simple clinical and life-style features. 
• But for prevention, first we need to accurately predict the stroke.
• So, we designed this app to predict stroke with 95% precision, recall and F-1 score and astounding 99% AUC-ROC on actual patients' data. The analysis is based on an excellent research paper in the reputed journal nature.
• A functional streamlit app built by us is deployed here.

• This is loan eligibility chatbot based on real data of a US financial institution.
• User enters various options and a profile of user is built. 
• Instantly ‘Loan Approved’ or ‘Loan Not Approved’ decision is displayed with a message and image.
• User gets reasons which factors of his profile are helping approval and which are pulling against approval.
• The highlights of the app are its lightweight footprint which leads to real time decision and interpretablity of results.
• A very accurate and efficient random forest model. 

• This is a heart attack prediction app based on real data and easy features so that even a layman can do self-health check.
• Features are Gender, Age, CigarettesPerDay, BPMeds , PrevalentHypertension, Diabetes, TotalCholesterol, SystolicBP, DiastolicBP, BMI, HeartRate, FastingBloodGlucose.
• User enters value and he can see probability of heart-attack. A custom cut off of 42% was used to get the best F1-Score so as to minimize both false positives and false negatives to the most optimal level.
• A powerful XGBoost model with Grid search CV and 5 fold cross validation , having F1- score 96.7% was obtained for very precise diagnosis.
• Post-diagnosis, next stage is advising patient on what are the most important risk factors for him/her. Here EACH PATIENT IS DIFFERENT. So, it is possible to see which factors are pulling the prediction to 1 heart-attack (red) and which are pulling to 0 no heart-attack. (blue). A new diagram is generated for each patient based on values entered by him.

• This is a highly scalable customer churn application using real data (10000 rows)  of a multinational European bank.
• The business problem is:

1.  To predict which customers are likely to churn based on customer's features and history.
2. To find mean and median churn probability for  each feature-group for  the high churn list.
3. To study which factors are causing churn and which are preventing churn for an individual customer.
4. To develop a Flask app with JavaScript, HTML, CSS and trained XGB model and deploy on AWS.

• Data science problem is  to do binary classification, to create a reproducible pipeline , try different algorithms and find the best algorithm. Extensive data preprocessing and feature engineering are involved.

• This is a standalone python app with minimal footprint but great features.
• User uploads CSV or XLSX data file as input. Size of the data set is limited only by user's hardware capacity. 
• App displays necessary EDA information and statistical summary.
• User selects his response variable for binary or multi-class classification. 
• App allows user to select one of 13 classification algorithms. 
• User adjusts hyper-parameters for chosen classifier by convenient controls. 
• For each classifier and each set of hyper parameters the model training and Evaluation are performed independently and evaluation metrics and classification reports are seen in output-2. During training data pre-processing steps are also performed in the pipeline meaning that input data need to be 100% clean.
• Once the best classifier and best hyper parameters are chosen based on characteristics of data and the use-case, the user can plot seven different types of plots.
• Below each plot helpful short information is printed explaining how to use that plot for interpretation and inference.
• The application be easily ported to be deployed on any OS or on web.

• This is the POC version of a real life project executed by us for a real-estate consultant firm having operations in six metro-cities of India. Actual production app had a dedicated database to store client data.
• It is a multi-page python flask application which can be deployed on any cloud. 
• Real and recent (2022) price data of six Indian metros (Mumbai, Delhi, Kolkata, Chennai, Hyderabad and Bengaluru) was used.
• As data distribution for each city was different, six different pickle models - one for each city- were prepared.
• As location was affecting price in same city, so, location was kept as feature. However, presence of hundreds of location made it challenging to design the app and subsequent testing.
• Many regression algorithms were tried  before deciding on XGBOOST with  5 fold cross validation and grid search CV to decide on the optimal hyper parameters.
• Impressive evaluation metrics were obtained for both train and test set. Even in actual production environment performance was very good. 
• Later, on client's request, new features like RERA approval status, rental yield and a recommendation systems.were added.
