Sheryl Sandberg: Develop Your Voice, Not Your Brand [Theodore Kinni / Stanford GSB ]

The idea of developing your personal brand is a bad one, according to Sandberg. “People aren’t brands,” she says. “That’s what products need. They need to be packaged cleanly, neatly, concretely. People aren’t like that.”

“Who am I?” asks Sandberg. “I am the COO of Facebook, a company I deeply believe in. I’m an author. I’m a mom. I’m a widow. At some level, I’m still deeply heartbroken. I am a friend and I am a sister. I am a lot of very messy, complicated things. I don’t have a brand, but I have a voice.”

How to Monetize Your Podcast by Selling Your Recording Equipment [Dustin Meadows / Hard Style ]

I was once like you. I thought, “man, I’ll bet there’s a lot of people out there who wanna hear about the plot holes I’ve discovered in the Marvel Cinematic Universe,” but it turns out like 10,000 other people have already made podcasts about the plot holes in the Marvel Cinematic Universe and about 9,998 of them were better than mine.

Facebook’s AI Robots Shut Down After They Start Talking to Each Other in Their Own Language [Andrew Griffin / The Independent]

Facebook abandoned an experiment after two artificially intelligent programs appeared to be chatting to each other in a strange language only they understood.

The two chatbots came to create their own changes to English that made it easier for them to work – but which remained mysterious to the humans that supposedly look after them….

The robots had been instructed to work out how to negotiate between themselves, and improve their bartering as they went along. But they were not told to use comprehensible English, allowing them to create their own “shorthand”, according to researchers.

Demystifying data science

The key to a successful analytical model is having a robust set of variables against which to test for their predictive capabilities. And the key to having a robust set of variables from which to test is to get the business users engaged early in the process.

How machine learning is shaking up e-commerce and customer engagement

From a content perspective, [Sitecore] performs semantic analysis to:

  • Auto generate taxonomies and tagging
  • Help improve the tone of your content by analyzing for things like wordiness, slang, and other grammar-like faux pax

From a digital marketing perspective, ML can:

  • Help detect segments of your customers or audience
  • Improve the effectiveness of your testing and optimization processes
  • Provide content and product recommendations that increase the engagement time a customer spends on your website.

And from a backend perspective, it can help with fraud detection, something that every company with an e-commerce model needs to monitor actively.

Gartner 2017 magic quadrant for data science platforms: gainers and losers

Firms covered:

  • Leaders (4): IBM, SAS, RapidMiner, KNIME
  • Challengers (4): MathWorks (new), Quest (formerly Dell), Alteryx, Angoss
  • Visionaries (5): Microsoft, H2O.ai (new), Dataiku (new), Domino Data Lab (new), Alpine Data
  • Niche Players (3): FICO, SAP, Teradata (new)

Gartner notes that even the lowest-scoring vendors in MQ are still among the top 16 firms among over 100 vendors in the heated Data Science market.

Among those not on the quadrant, I’ve been impressed by DataRobot.

Emotion Detection and Recognition from Text Using Deep Learning

The researchers used a data set of short English text messages labeled by Mechanical Turkers with five emotion classes anger, sadness, fear, happiness, and excitement. A multi-layered neural network was trained to classify text messages by emotion. The model was able to classify anger, sadness, and excitement well but didn’t do well at recognizing fear.

Adapting ideas from neuroscience for AI

We don’t really know why neurons spike. One theory is that they want to be noisy so as to regularize, because we have many more parameters than we have data points. The idea of dropout [a technique developed to help prevent overfitting] is that if you have noisy activations, you can afford to use a much bigger model. That might be why they spike, but we don’t know. Another reason why they might spike is so they can use the analog dimension of time, to code a real value at the time of the spike. This theory has been around for 50 years, but no one knows if it’s right. In certain subsystems, neurons definitely do that, like in judging the relative time of arrival of a signal to two ears so you can get the direction.

Five AI Startup Predictions for 2017

My favorite: “Full stack AI startups actually work”

When you focus on a vertical, you can find high level customer needs that we can meet better with AI, or new needs that can’t be met without AI. These are terrific business opportunities, but they require much more business savvy and subject matter expertise. The generally more technical crowd starting AI startups tend to have neither, and tend to not realize the need for or have the humility to bring in the business and subject matter expertise required to ‘move up the stack’ or ‘go full stack’ as I like to call it.
