Word2Vec Experiments
In this post, I’ll describe some experiments on word2vec, a technique invented by researchers at Google that aims to find compact vector representations for words […]
Understanding Data Parallelism in Machine Learning
In this post, I’ll show how to modify the spiral data set example presented in Karpathy’s post (http://cs231n.github.io/neural-networks-case-study/) to run in a data parallel mode. […]
Building a 2 Layer Network to Classify a Spiral Dataset using Matlab and CNTK
The purpose of this post is to provide some additional insights and Matlab and CNTK implementations for the two layer network used to classify a […]
Calculating the Derivative of the Error with respect to Convolution Filter Weights in a CNN
Over the last month, I have been exploring the world of deep learning. Deep learning based algorithms have been around for a long time, but […]
Calculating Position from Raw GPS Data
We are all familiar with GPS (Global Positioning System) and its myriad applications. From getting directions using Google maps to hailing a ride using a ride sharing […]
Sensor Fusion: Part 4
In this post, we’ll add the math and provide implementation for adding image based measurements. Let’s recap the notation and geometry first introduced in part […]
Sensor Fusion – Part 3: Implementation of Gyro-Accel Sensor Fusion
In the previous posts, we laid the mathematical foundation necessary for implementing the error state kalman filter. In this post, we’ll provide the Matlab implementation […]
Sensor Fusion: Part 2 (combining Gyro-Accel data)
In the previous post, we laid some of the mathematical foundation behind the kalman filter. In this post, we’ll look at our first concrete example […]
Sensor Fusion: Part 1
In this series of posts, I’ll provide the mathematical derivations, implementation details and my own insights for the sensor fusion algorithm described in 1. This paper describes a […]
