We’re back with our round-up of the biggest news on big data, business intelligence, and data visualization. Going forward, we’ll be doing this on a bi-weekly schedule, which we think would be the ideal frequency.
1. Explaining machine learning to non-computer-science people
Quora is a great place to find nuggets of interesting conversations between prominent thinkers today. One conversation particularly caught my interest this week. It seeks to put machine learning in common man’s terms. Many people pull out their best stories, and examples to explain it best, but the top voted reply is entertaining illustration from the way we pick mangoes in the market. It’s a great read for experts in the topic who are looking for an easy way to explain what they do, or for novices seeking to wrap their minds around this new phrase. Here’s an excerpt:
You take a randomly selected specimen of mangoes from the market (training data), make a table of all the physical characteristics of each mango, like color, size, shape, grown in which part of the country, sold by which vendor, etc (features), along with the sweetness, juicyness, ripeness of that mango (output variables). You feed this data to the machine learning algorithm (classification/regression), and it learns a model of the correlation between an average mango’s physical characteristics, and its quality.The writer, ends with a catchy definition of machine learning: “Making your algorithms smart, so that you don’t need to be. ;)”. Head over to Quora and read this and the other amusing stories. It’s probably the lightest read on this otherwise heavy topic. 2. Facebook’s white paper ‘A Focus on Data Efficiency’ This past month Facebook, Qualcomm, and Ericsson released an extensive white paper on how they’re driving efficiency working with data, and the challenges they face with existing spectrum standards. Here are some of the main pointers from the white paper:
- How Facebook built and open-sourced the HipHop Virtual Machine execution engine and achieved a 500% increased in server throughput
- How Open Compute technologies allows Facebook to house 250 billion photos without hang ups
- How Facebook created Air Traffic Control to help engineers handle different network conditions like bandwidth, latency, packet loss, corrupted packets, and packet ordering
- Facebook uses Google’s WebP image compression technology to save over 20% of total network traffic, without loss of image quality
- Qualcomm is working on technology that can handle 1000 times more network traffic than today
