Jack Fitzsimons | Evil Models: Hiding Malware in Neural Networks

Did you know that it's possible to hide malware in neural networks? Actually, you can hide malware in many statistical models. This is the subject of two recently-published papers (aptly titled "EvilModel" & "EvilModel 2.0"). Dr. Jack Fitzsimons makes it easy to understand how this is done, using techniques that began long before computers.

Chris Tosh | The piranha problem in statistics

Épisode 82

mardi 22 février 2022 • Durée 01:09:41

The piranha problem (too many large, independent effect sizes influence the same outcome) has received some attention on Andrew Gelman’s blog. But now it’s a paper! Chris Tosh (Memorial Sloan Kettering) talks about multiple views of the piranha problem and detecting the implausible scientific claims that are published. The butterfly effect makes an appearance.

If you enjoyed the science-vs-pseudoscience topics, you’ll enjoy this one.

Charlotte Deane | Bioinformatics, Deepmind's AlphaFold 2, and Llamas #datascience #ai

Charlotte Deane (Oxford University) talks about statistical approaches to bioinformatics, the evolution of Google Deepmind's AlphaFold 2 & its place in protein informatics deep learning landscape. She also describes humanizing antibodies, and the increasing role of software engineers in statistical research groups. The topic of llamas, camels, and alpacas (and their unique place in proteomics research) makes a surprise visit.

Eric Schwitzgebel | Consciousness, Zombies, & First Person Data | Philosophy of Data Science

Épisode 78

jeudi 2 décembre 2021 • Durée 01:13:24

The philosophical community continuously aims to reconcile differing views on first person data and the consciousness of the mind. Is it possible to live without consciousness? Can one conceive thoughts without matching images to them? In this episode, Eric Schwitzgebel of the University of California tries to dissect such topics and questions to help us better understand the philosophical world.

Keywords: philosophy, epistemic data, first person data, stimulus error, imageless thought, consciousness

Jingyi Jessica Li | Statistical Hypothesis Testing versus Machine Learning Binary Classification

Jingyi Jessica Li (UCLA) discusses her paper "Statistical Hypothesis Testing versus Machine Learning Binary Classification". Jingyi noticed several high-impact cancer research papers using multiple hypothesis testing for binary classification problems. Concerned that these papers had no guarantee on their claimed false discovery rates, Jingyi wrote a perspective article about clarifying hypothesis testing and binary classification to scientists.

Gualtiero Piccinini | What Are First-Person Data?

First-person methods (and its associated data) have been scientifically and philosophically contentious. Are they pseudoscientific? Or simply pushing the bounds of scientific methodology? Obviously, I have no idea… so Prof. Gualtiero Piccinini (University of Missouri – St. Louis) provides a helpful introduction to the topic covering the key points of its history and the philosophical/scientific debate.

0:00 Why cover first-person methods & data? 2:26 First-person methods vs first-person data? 7:10 Are first-person data legitimate at all? 11:50 Phenomenology 13:26 First-person data is extracted from human behavior 18:25 Skepticism & arguments against first-person data 25:40 Psychophysics, introspectionists, behavioralists, cognitivists, and the origins of first-person data 35:20 Using new instruments & methods in science 46:00 Is this where the philosophers roam?
