Deep Neural Network Autoencoder for Data Compression in High Energy Physics at CERN ATLAs

Large Hadron Collider is the world's largest and highest-energy particle collider with the ATLAS detector generating 1 petabyte of raw data and 40 million packets of protons colliding every second. High collision rate 20 MHz means not all events can be stored. A particle physics trigger system selects specific events. The goal is to reduce the size of the data by engineering a compression algorithm for the trigger system.

Autoencoder neural networks were used for data compression and anomaly detection. The two part encoder and decoder system compresses hadron jet event data from 4 to 3 variables. It was trained over a dataset to encode the inputs into a smaller memory space with PyTorch, FastAI Library, ROOT Data Analysis Framework, and CERN ATLAS Docker images. Analysis includes plots and graphs to explain the concepts of invariant mass, purity selection, trigger efficiency, and hadron event reconstruction.

Yeezy Taught Me Text Generation - Train Next Character Prediction using Long Short Term Memory Model (LSTM)

LSTM is one of the most commercial AI achievement used in time series prediction, speech recognition, music learning, handwriting recognition, and sign language translations. Yeezy Taught Me is a web application for AI model training and text generation. Trained LSTM model to generate text based on patterns in a given text corpus. Yeezy's Model makes probability predictions of the character that follows the input sequence. Process is repeated in order to generate a character sequence of a given length hence the "text generation" part of the project.

Input file takes input text data. Model saved in IndexedDB database. User inputs Yeezy's model parameters to train model: [model layer size, number of epochs, examples per epoch, batch size, validation split, or learning rate].

Stochastic SoundCloud - Lucy’s New Mozart Mixtape. Machine Learning Generative Music using RNN LSTMs

Stochastic SoundCloud uses machine learning to generate melodies as music is an art with a temporal and hierarchical structure. The output musical state is partially determined by the preceding musical state where the concrete musical state n+2 follows after the state n+1. Piano roll representation is a music storage data type where a music piece is represented by a score-like binary valued (0 XOR 1) matrix representing music notes over different time step. Piano roll of each bar and track for generated data is represented as a fixed-size matrix for M tracks.

Music generation with three novel recurrent neural networks (basic, lookback, and attention RNNs) using Magenta from Google's Tensorflow AI. Lookback and Attention RNNs are proposed to tackle the problem of creating the melody’s long-term structure. It was fed with a chord sequence and outputs a Prediction Matrix, which was transformed into a piano roll matrix and into a melody MIDI file. 10 stochastically generated "output.mid" music files are composed and opened up on Mac's Garageband.

En Français Si Vous Plait? French-English Natural Language Processing (NLP)

Vision of connecting people through language and advancing a barrier free society for billingual speakers. As a Canadian citizen, ensure respect for English and French as the offical languages of Canada and have equality of status, rights, and privileges.

French-English translations using PyTorch’s Transformer model and paper implementation of "Attention is All You Need”. Led the development of the machine language translation transformer model uses encoder-decoder attention mechanisms in a sequence-to-sequence model. "On the WMT 2014 English-to-French translation task, model establishes a BLEU score of 41.8 after training for 3.5 days on eight GPUs, a small fraction of the training costs of the best models from the literature"

Salty Wet Man - Not Suitable for Work (NSFW) Image Classification using VGG16 Neural Network

Inspired by the #Metoo and #Timesup movements in the fight for gender equity in the workplace to create safe economic opportunities for women. Salty Wet Man is a Not Suitable for Work image classification trained on the ImageNet dataset. Defining NSFW material is subjective and the task of identifying these images is non-trivial. Salty-Wet-Man identifies images into two categories: [SFW] positively trained for neutral images that are safe for work [NSFW] negatively trained for pornographic images involving sexually explicit images.

CNN for large-scale image recognition model implementation achieves object recognition functionalities like Content-Based Retrival via Localization, Image Detection, and Segmentation, and Image Region Proposal Cropping.
