Bio

Vincenzo is a data scientist with five years of professional experience. For three years, he worked for a product-data-focused eCommerce startup, in which his main areas were data cleaning and data classification using NLP tools. In this primarily remote and customer-facing position, he had to understand and implement the customer's needs. During his free time, he is a successful Kaggle and Numerai participant and loves solving complex problems.

Work Experience

Data Analyst

2019 - 2021
ONEDOT
  • Led and worked on the integration of product data into the customer's system with the help of machine learning and NLP tools, namely translation, cleaning and enhancing of product descriptions and classification of products.
  • Automated a daily two-hour process by automating the fetching, categorization, and integration of around 600,000 from 4-6 files with a daily varying layout.
  • Managed, engineered, tracked, and simultaneously implemented requirements for up to four data processing and integration projects.
  • Led and partially implemented the solution to automate the daily integration of nearly 4.1 million products into the customer's system from around 50,000 semi-structured XML files.

Experience

Daily Auto-integration | The Product Data of 4.1 Million Articles

Led the implementation for the fetching of around 50,000 semi-structured XMLs containing product data of 4.1 million articles and combining them into one structured XML File (BMECat) while simultaneously enhancing the product data and classifying products.

Image Captioning

https://github.com/kenfus/ImageCaptioning
As part of a semester project, we implemented our solution to the image captioning task presented by vizwiz.com, where you need to describe the content of an image to people who are blind.

The architecture is basically as follows:

• A pre-trained CNN model, namely ResNet50. It is used to generate features from the images.
• With the help of an embedding, the dimension is adapted to the predefined vocab size, and the embedding dimension is selected based on available computing resources.
• This vector is then passed as the first hidden state in an LSTM, and a sentence is generated from it.

Deep Learning-based Question and Answering

https://github.com/kenfus/QuestionAndAnsweringOnSquad
For a semester project, we implemented and evaluated different models based on their performance on the Stanford question answering dataset (SQuAD) and our questions and contexts.

Based on its answers, we made a recommendation to our University.

Text Sentiment Analysis

https://github.com/kenfus/SentimentClassification
We evaluated with different metrics the performance of different methods, namely deep learning to SVC to Bayesian models, to analyze the sentiment of reviews.

For each metric, we presented the best method and where this metric could be the most important.
