Twitter's Jack Dorsey is being pressured by a bunch of social media reporters from CNN to silence voices like Alex Jones; and all of the big socials are caving in fast. It's time to unmask the seemingly reasonable justifications for these bans for what they are - censorship. I add to the voices calling for a freer flow of information, and I call for entrepreneurs, engineers, and product designers to come up with a new generation of platforms that will be better than the old. We also talk about m...

Today we dive into the current Bayesian flame wars on Twitter. Do Bayesian priors converge? As Nassim Taleb (@nntaleb) points out, not necessarily until a fat tail or power law distribution. We'll talk about what that means, and the wonders worked by Bayes rule even under some seemingly preposterous priors. Also - the military wants to do machine learning with less data. Is the era of big data over and giving way to the era of the big algorithm? The results of the Twitter Shadow Ban poll, QA bia...

I may be on vacaction, but I still snuck in some time to put together a show! Decided to go solo this week and focus on Twitter's purging of bots and trolls. There is wide agreement that they need to do something to fix their platform, but there is not wide agreement on what exactly the problem is and what should be fixed. Can they focus on the experience and wellbeing of their enduser, or will they fall victim promoting fashionable political trends and end up with censorship? Get full access to...

So the overall theme of the show today is applying what we learned last time. Bayesian Probability is good. P-Value hacking - is where we get into trouble. Death to P-hacking! We start by following up on my monologue from last week about Beliefs and Probability. This leads us into an article about the Reverend Thomas Bayes himself, and how his ideas transformed our thinking on probability and belief. And finally, are most of the scientific studies that you hear about wrong? Worry about p-hacking...

I explore the nature of probability, and my approach to thinking about facts and belief. I talk about problem solving a lot; here I go into the fundamentals and work to justify how I think about it. What problem does probability solve? Should we always think in terms of probability? What's the difference between an artificial language (code, math) and natural language? How many water molecules are in the Atlantic Ocean? Sometimes we have vague questions and make vague statements - should that be...

An article about MIT research claims that they've built a psychopathic AI. We think the article is a little off base, and try to determine what's actually going on.

I also check in with Christian Hubbs, host of Artifically Intelligent, about his podcast. I was interviewed for todays episode, so check that out! I also define a Convolutional Neural Net,...

Today's concept is underfitting vs. overfitting. Someone who underfits doesn't adapt quickly enough to new data. But if you think that's bad, an overfitter will read TOO MUCH into new data and come up with wild ideas. How do you balance between them and what are some examples? We also talk about Warren Buffet's Recent statements on Bitcoin as Rat Poison Squared, and the response from Union Square Venure's Fred Wilson. How does Bitcoin get it's value? We look at underfitters and overfitters in th...

Aaron comes back on the program to discuss the Mark Zuckerberg testimony before congress, particularly the part pertaining to moderation and censorship. In the last episode, I described the current approach that companies like Facebook, Twitter, and Google have towards this problem and why it might be flawed. Today, we see this theory play out in the Facebook CEO's answers. We discuss the case of Diamond and Silk, which I mentioned last week but had no idea would appear in the hearings. Also, Fa...

Don't hold your breath expecting them to try out my proposal! I also discuss Lindy's Law, which is a helpful rule of thumb in technological and social forecasting.

The big news right now is around an analytics company that used a dataset from Facebook - gotten by the company under false pretenses - to help the Trump campaign in 2016. Everyone is SHOCKED - but this kind of data mining was glorified and extolled as a social good when it was used for Obama in 2012. The comparison of the coverage is stark. How are we going to get out of this? What exactly is the problem? I think that the vast centralization of data services has led to all sorts of problems, an...
