Blog Post 8 Optimizing the NN This week I began testing different configurations of Neural Nets with tensorboard to find out which gave the most promising results. Previously , when I was training on the raw wav data, I found the best results with models that included 1 or more 1D Convolutional layers. Interestingly, when …

Week 9 (2/9/19)
Blog Post 7 Data Issues: This week came with a couple of setbacks and some pretty cool break throughs. At the end of last week I had a pretty robust model that could acuratley classify a sound file on weather it had been recorded in one of two rooms. After this I decided to up …
Week 8 (26/8/19)
Blog Post 6 More Data This week was all about generating more data. Data Management
Week 7 (19/8/19)
Blog Post 5 Week 7 Dataset management This week I began using the tensorflow library with my data to generate some preliminary neural nets and test out which models performed best. After looking at a plotted graph of my wav file data set I realised that the majority of useful information was contained in the …
Weeks 4/5/6
Due to a combination of things, I’ve recently had to put the project about a half ways on hold. As such I haven’t had a chance to update the blog recently, so this post will cover my progress over the last few weeks from 24/7/19 to the end of this week 9/8/19. Permissions Granted / …
Week 3 (15/7/19)
Blog Post 3 Muiredach O’Riain week: 3 Starting: 15th July 2019 – 15/7/19 GNN – An exciting development for this project came early in the week when I was put in touch with Roger Dev, the leader of HPCC Systems Machine Learning Library. Roger and his team are currently developping a Generalized Neural Network (GNN) …
Week 2 (8/7/19)
week: 2 Starting: 8th July 2019 – 8/7/19 Goal For this week was to finish extracting the .wav files from the .mat files and batch convolving code. Distorted files Emailed the people at Aachen University for the .wav file version of the IRs, not in the .mat files, however they were 24bit files which wavefile.read() …
Week 1 (1/7/19)
Muiredach O’Riain week: 1Starting: 1st July 2019 – 1/7/19 My main plan for this week was deciding Deciding Upon and Defining the Relevant Features to ClassifyFinding relevant Impulse ResponsesFinding a series of clean sounds to be convolved as a basis for the training data The problem of finding suitable Impulse Responses solved thanks to the …
What’s the big idea?
The goal of this project is to use HPCC Systems technology to help build a reliable classification model that is able to accurately classify an input sound file to a description of its location. The project intends to not only demonstrate a proof of concept for this technology but also to lay the groundwork for what …
