Sentence2Vec

Final Paper of research on using word-embeddings to improve students learning using Machine Learning.

Code cannot be shared due to data confidentiality and sensitivity.

Technologies Used: Python, Keras, gensim, Pandas.



Youtube Videos Data ETL using AWS

Using AWS Athena, Glue, Lambda, Spark, I created a fully functional data catalog using AWS technologies.

Using Youtube video data from a Kaggle commpetition, the data catalog contians raw, queriable, and processed (transformed) data. The user can run MySQL queries to retrieve data and then move data to processed data and display graphs and charts for visualization.

Technologies Used: Python, AWS

Future Salary App

Scrapped more than 20,000 data and tech related jobs in main cities of the United States to create a Salary Predictor using NLP and Machine Learning Algorithms.

I used Beautiful Soup and Selenium to first retrieve text data and then automatize the process. The metadata contained features such as name, location, description, and others. Based on the exploratory analysis of my data, I created custom salary buckets to target the regression prediction.

Technologies Used: Python, Scikit-Learn, PyTorch, gensim, Heroku, Streamlit.

Toxic Text Dectector App

Using a previous Kaggle Competition data and advanced Machine Learning algorithms, I created an Mutilabel Predictor of toxic text data.

Technologies Used: Python, Seaborn, Streamlit, Flask, Heroku, NLTK, Scikit-Learn.

Spotify Models
Spotify Project Part 3 - Classification Modeling and Comparison

I used the Logistic Regression as the based model to compare with other Machine Learning Classification models. This part of the project was an opportunity for me to learn more about other Machine Learning Models that I didn't know before.

Technologies Used: Python, Scikit-Learn, XGBoost and LightGBM imports, Spotify's API (Spotipy).

Spotify Project Part 2 - EDA & PCA Construction

We continue from Part 1 to proceed to explore the streaming history dataset and their Spotify's features. In this part of the project we focus more in what is the internal sense of the dataset.

Also, I extract other playlists such Weekly Discover and my Liked Songs playlists that we later used for Machine Learning modeling purposes.

I used Seaborn and Plotly to explore the data through an incisive EDA. Then, discuss the idea behind the PCA algorithm for dimensionality reduction and proceed to construct the PCA algorithm from scratch.

Technologies Used: Python, Numpy, Seaborn, Plotly, Spotify's API (Spotipy).

Spotify Project Part 1 - Spotify Features & Data Extraction

First part of a series of 3 parts series using my own data from Spotify. I requested Spotify to send me all the data that they could collect from my user account.

Here I used my year-long streaming history that I requested to add each song the Spotify's features that the music platform uses for their own recommendation algorithms. I wrote a Python script to interact with Spotify's API and extract the important information.

Technologies Used: Python, Spotify's API (Spotipy).

Santiago's Accident Prediction Classifier

This is the final project of the Graduate version of the class Data 100/200: Principles of Data Science at Berkeley.

I wanted to explore my homecity, Santiago, Chile, casualties in vehicle accidents data and construct a Classifier that may predict when and what streets are more likely to cause deathly accidents. The goal here is to help authorities to use better their resources and create policies based on data to help to prevent life losses.

Data was obtained from various places such as the Chilean Congress Library, OpenStreetMap, and official Chilean police data reports of accidents.

Technologies Used: Python, GeoPandas, Seaborn, Scikit-Learn

BearMaps + Trie Data Structure

This is one of the assingments in another Berkeley course, CS 61B: Data Structures. In this project I did an extra function to the project which it creates a Trie Data Structure from scratch.

Unfortunately, I can't share the code publicly because of the class's policy.

Technologies Used: Java



This Website

I wrote this website from scratch. I always wanted to have my own website. I hope you like it! :)

Technologies Used: HTML, CSS, Javascript, Bootstrap
