Portfolio Projects

Description

Our dataset contains the sample of candidates of a company who is facing challenge that about 30% of the candidate who accept the job offers but do not join the company. So with the help of Decision Tree algorithm, ‘gini’ as criterion, I build a model to predict the likelihood of candidate joining the company.

Description

Objective: A health condition when liquid is accumulated in lungs, with the help of neural network based model we tried to classify x-ray image of chest whether is person have pleural effusion or not. 

Solution: Training resnet18 architecture on x-ray image with user-defined callbacks. Methodology: Pre-processing image data and data augmentation with the help of keras.
Performing Ablation experiment in small chunk of data to evaluate resnet18 architecture
Key Achievement: Developed a model with AUC score 87 % on validation data.
