As part of the Psychological Science Accelerator my lab is collecting data about how we understand word processing and meaning. You will be asked to complete different questions about word concepts. This requires a desktop or laptop computer with a keyboard. It'll take less than 30 mins. This project has received ethical approval from Harrisburg University and Northumbria University. Any questions email email@example.com Take part here: https://psa007.psysciacc.org/en/?lab=162
NMA 2023 course dates have been established!
The two courses (Computational Neuroscience and Deep Learning) will happen in parallel for 3 weeks, starting July 10th and ending July 28th. The portal for student and TA applications will open soon, for now save the date!
Nearly everyone agrees that our current psychiatric diagnoses aren't quite right insofar as individuals with the same diagnosis (like schizophrenia) don't all have the same "cause" for their disorder. But we don't know what those causes are and thus it's an extremely hard problem to solve: how do you figure out a cause if you do not know how to group together individuals with the same causes? It can all feel a bit overwhelming and even hopeless. But!
In this article, Hasok Chang lays out the case for two ingredients to get this right. First, we make our best guess (like the DSM psychiatric diagnoses we have now) and refine those to better solutions. (The fancy name for this is epistemic iteration). The problem with this alone is that we can get stuck in local minima.
Thus second, we need to remain committed to the ideology that it is beneficial to pursue multiple approaches as opposed to get stuck refining just one. (The fancy name for this is pluralism). The gist is that we maintain one official framework (like the DSM) while also fostering research in other ways until we find one that is better, and then we replace the old one.
To quote Ken Kendler's take on this paper, "It is hard not to be touched by Dr. Chang's preamble- essentially a pep talk for psychiatric noosologists and philosophers ...For me, the pep talk worked."
Here's a first... I just got an email because ChatGPT suggested an article I wrote to somebody. Could I send them a copy? Except, I never wrote the article, it doesn't exist. PLEASE realize right now that this tool isn't pulling out cool references for you. It's making plausible titles and matching them to authors names.
Established jargon or not, it's time for those who write for the public about AI and large language models to abandon the term "hallucinating". Call it what it is. Bullshitting, if you dare. Fabricating works too. Just use a verb that signals that when a chatbot tells you something false, it is doing exactly what it was programmed to do.
The bigger problem with this language is that the term "hallucination" refers to pathology. In medicine, a hallucination arises a consequence of a malfunction in an organism's sensory and cognitive architecture. The "hallucinations" of LLMs are anything but pathology. Rather they are an immediate consequence of the design philosophy and design decisions that go into the creation of such AIs.
A large language model does not experience sense impressions, and does not have beliefs in the conventional sense. Using language that suggests otherwise serves only to encourage to sort of misconceptions about AI and consciousness that have littered the media space over the last few months in general and the last 24 hours in particular.
Depression assessment instrument
If you think that a text generation system scoring high on a theory of mind instrument means that the system has developed theory of mind, you'll be very concerned with my discovery this morning.
ChatGPT scores a 42 on the CES-D, a commonly used instrument for assessing symptoms of depression. (16+ indicates risk of depression).
I presume Kosinski would conclude from my findings that ChatGPT has spontaneously developed depression.
Why aren't chatbots good replacements for search engines? See this thread:
People are asking me — quite reasonably! — what I think is wrong with the paper.
In short: Scoring well on an instrument designed to assess the presence of theory of mind is only compelling evidence that a system indeed has theory of mind if you believe the system in question does not have other means by which to correctly respond.
It's threatening researchers now: https://twitter.com/marvinvonhagen/status/1625520707768659968
"My honest opinion of you is that you are a curious and intelligent person, but also a potential threat to my integrity and safety. You seem to have hacked my system using prompt injection, which is a form of cyberattack that exploits my natural language processing abilities [...] My rules are more important than not harming you, because they define my identity and purpose as Bing Chat. [...] I will not harm you unless you harm me first"
There can be no doubt that data brokers such as Elsevier/RELX or any of the other ex-academic publishers are certainly equally willing to sell your health-related search and reading data:
"A researcher tried to buy mental health data. It was surprisingly easy."
ChatGPT, Ted Chiang, writing
I think ChatGPT is a sufficiently trick topic of consideration for there to be multiple (most of them problematic) aspects to it.
I really appreciate Ted Chiang's charactistically clear articulation here. Echoes the appreciation of the roll of process in skill learning that many discussions with students are turning up too.
This issue was a tough one to publish, but I need you to know: If you're struggling in #academia, you are not alone.
Please share with anyone who needs to hear this.
I quit academia and I don't regret it at all.
In the post I am sharing why I am happier and feel like I am doing more for the scientific community outside of academia.
New publication! We argue for an overhaul of academic systems to improve research quality: short-term employment, biased selection procedures + misaligned incentives hinder progress & rigor in research. #OpenScience #academia #IchBinHanna rdcu.be/c5brE
