We See in 3D – So Should Our CNN Models

Summary:  Autonomous vehicles (AUVs) and many other systems that need to accurately perceive the world around them will be much better off when image classification moves from 2D to 3D.  Here we examine the two leading approaches to 3D classification, Point Clouds and Voxel Grids.

 

One of the well-known…

Automation Eliminates Expensive Data Entry Errors

Organizations rarely regard data entry as a key strategic operation. In spite of the rise in automation, companies across the world rely on manual data entry for procurement. They employ staff to transfer data from requisition orders, purchase orders, and invoices into enterprise resource planning (ERP) systems such as SAP, Oracle, PeopleSoft, Netsuite, and many others. 

Transcription and transposition errors are…

Executive Mandate #1:  Become Value Driven, Not Data Driven

I hate it when I hear senior executives state that they want to become data-driven, as if somehow having data is value in of itself.  Now, one can hardly blame the unenlightened executive whose only perspectives on data are associated with statements like “Data is really the new oil” (Wall Street Journal) or “…

Artificial Neural Networks in a Nutshell

According to Wikipedia, an ANN is based on a collection of connected units or nodes called artificial neurons, which loosely model the neurons in a biological brain. Each connection, like the synapses in a biological brain, can transmit a signal to other neurons. An artificial neuron that receives a signal then processes it and can signal neurons connected to it.

In ANN implementations, the "signal" at a connection is a real number, and the output of each neuron is computed by some…

AI Trading the Market

Written by Jun Wu.

Every year since I worked on wall street, traditional trading-is-an-art-form traders are leaving and retiring.

Their jobs are replaced by a new breed of experts who are savvy with numbers, systems, and the market. These experts don’t sleep, eat or drink. They are the AI Systems that can run on a thousand machines to…

The Math of Machine Learning - Berkeley University Textbook

This document is an attempt to provide a summary of the mathematical background needed for an introductory class in machine learning, which at UC Berkeley is known as CS 189/289A.

Our assumption is that the reader is already familiar with the basic concepts of multivariable calculus and linear algebra (at the level of UCB Math 53/54). We emphasize that this document is not a replacement for the prerequisite classes. Most subjects presented here are covered rather minimally; we intend…

The simplest explanation of machine learning you’ll ever read

This article was written by Cassie Kozyrkov.

 

You’ve probably heard of machine learning and artificial intelligence, but are you sure you know what they are? If you’re struggling to make sense of them, you’re not alone. There’s a lot of buzz that makes it hard to tell what’s science and what’s science fiction. Starting with the names…

AWK -- a Blast from Wrangling Past.

I recently came across an interesting account by a practical data scientist on how to munge 25 TB of data. What caught my eye at first was the article's title: "Using AWK and R to parse 25tb". I'm a big R user now and made a living with AWK 30 years ago as a budding data analyst. I also empathized with the author's recountings of…

Applications of Data Analytics

I am presenting at the upcoming NISS (National Institute of Statistical Sciences) webinar on September 27. This was my first employer in US, back in 1996. I was then completing a post-doc.

My presentation focuses on new algorithms, original applications, theoretical data science (including a new conjecture about data sets) and implications to business analytics, as well as new foundations of statistics, based on general resampling and model free, data-driven techniques. It will also…

How AI/ML Could Return Manufacturing Prowess Back to US

I grew up in a small manufacturing town in Northeast Iowa.  The factory in my hometown made tractors (no surprise given that it was Iowa), but eventually the economics of cheap foreign labor and an interconnected global economy caught up with that factory – as it did with many US-based manufacturers – and soon the factory closed, and many people were laid off.

But the technology world continues to evolve – especially with respect to IoT, Data Science and AI/ML – and so…
