Goals

• Design a system that utilizes NLP techniques to extract meaning from support ticket text.
• Automate ticket classification by assigning relevant tags and routing tickets to appropriate support teams.
• Reduce support resolution times by ensuring tickets reach the specialists best equipped to handle them.

Challenges

• Natural language ambiguity: Interpreting the intent and meaning behind different writing styles and terminology.
• Handling unstructured data: Support tickets can contain informal language, typos, and varying formats.
• Evolving customer language: The system needs to adapt to new terminology and phrasing used in support requests.

Achievements

• Developed a support ticket categorization system with high accuracy in classifying incoming tickets.
• Leveraged large language models and transformers to extract key information and assign relevant tags to tickets.
• Designed the system to be scalable and adaptable to evolving customer language patterns.

Project Purpose

Build a robust image classifier using Convolutional Neural Networks (CNNs) to efficiently differentiate between plant seedlings and weeds, improving crop yield management.

Goals

• Develop a CNN model capable of accurately classifying plant seedlings from images.
• Minimize human involvement in seedling identification for faster and more efficient agricultural practices.
• Improve crop yields by enabling targeted weed control and resource allocation.

Challenges

• Image variability: Ensuring the model can handle variations in lighting, image quality, and plant growth stages.
• Class imbalance: There might be more images of certain plant species compared to others.
• Overfitting: Preventing the model from memorizing training data and performing poorly on unseen images.

Achievements

• Developed a CNN model with over 95% accuracy in classifying plant seedlings from images.
• Implemented data augmentation techniques to address image variability and class imbalance.
• Designed a scalable model to handle large datasets with diverse plant species and environmental conditions.

Project Purpose

• Develop a neural network model to predict customer churn for a bank, enabling proactive retention strategies.

Goals

• Design and train a neural network model to analyze customer data and identify churn risk.
• Evaluate model performance using relevant metrics like accuracy and F1 score.
• Provide recommendations for customer segmentation and targeted marketing campaigns.

Challenges

• Data preprocessing: Cleaning and preparing customer data for neural network training
• Hyperparameter tuning: Optimizing neural network architecture and parameters for optimal performance.
• Model bias: Mitigating potential bias in the model that could lead to unfair customer segmentation.

Achievements

• Achieved over 85% accuracy in predicting bank customer churn.
• Utilized feature importance analysis to identify key factors driving churn, such as account activity, product usage, and customer satisfaction levels.
• Fine-tuned the neural network architecture to improve model performance and minimize false positives.

This project aims to develop a robust Credit Card Users Churn prediction model to proactively identify customers at risk of canceling their service.

Project Purpose

Develop a predictive model to identify credit card users at risk of churning (canceling their service) and predict the reasons behind it.

Goals

• Build a highly accurate model to predict potential credit card users churn.
• Analyze the data to understand key factors influencing credit card users churn behavior.
• Generate actionable insights for targeted interventions to retain valuable customers.

Challenges

• Imbalanced datasets: A common challenge in credit card users churn prediction is the disproportionate number of customers who stay versus churn.
• Feature engineering: Selecting and transforming raw data into features that significantly impact the model’s ability to predict credit card users churn requires careful consideration.
• Model interpretability: Understanding how the model arrives at its credit card Users churn predictions is crucial for building trust and implementing effective interventions.

Achievements

• Achieved over 90% accuracy in predicting credit card user churn.
• Conducted feature importance analysis to identify critical factors influencing churn, such as spending habits, credit utilization, and customer service interactions.
• Developed a robust model using techniques like cross-validation and ensemble learning to improve generalization and avoid overfitting.
