Data Science Capstone Project
Explainable Deep Learning for Coral Classification
Coral taxonomy is currently undergoing a ‘molecular revolution’ which is fundamentally altering our understanding of the systematics and evolution of reefs. Importantly, molecular phylogenetic (tree of life) data is showing that micromorphological and microstructural features of the coral skeleton better reflect species evolutionary relationships than traditional macromorphological traits. While the combination of molecular phylogenetics and morphological analysis has facilitated better understanding of coral diversity, analysing microstructural features under the microscope is time-consuming and requires considerable expertise. Furthermore, this integrated taxonomic approach cannot be applied to the tens of thousands of coral specimens in the Queensland Museums (QM) collections collected before the time tissue preservation became necessary.
Machine learning could help overcome these problems by identifying and classifying species based on their skeletal morphology from high-resolution images, providing a valuable tool for coral taxonomy. Importantly, machine-learning tools could then be applied to accurately identify the extensive historical collections at QM, a task that would otherwise be completely unfeasible given the time required to examine each specimen.
The aim of the project is to build deep learning tools that can classify images of coral specimens into a hierarchical taxonomy also providing explanations for the picked category (e.g., using https://github.com/marcotcr/lime). Methods include the use of computer vision models (e.g., pretrained imagenet models or training models from available coral image datasets).

    Project's
    CyberBullying Detection in Social Media | Toxic Comment Classification Challenge | Kaggle
    Cyberbullying is a crime where one person becomes the target of harassment, racism, toxicity and hate etc. A sequential deep learning architecture: Embedding, Convolution, Max Pooling, Dense layers eliminates the need for feature engineering and produces better prediction than traditional machine learning approaches using the concept of word embedding using a high-level API of TensorFlow open-source library.

    Analyzing the Factors Affecting Delivery Time | Olist | Kaggle
    E-commerce has increasingly become more popular as well as customer's expectations. Olist, an ecommerce platform, does not always predict an accurate delivery time. We go through the data science process to reduce the error in estimating the delivery time. After explorative data analysis, we identify the features that contributes to the longer estimated delivery time. In consideration to the findings of the analysis we make recommendations that can be considered to improve delivery experience.
