#MonthOfArXiv

Oh wow, the past few days have been a lot. I will catch up with my #MonthOfArXiv, I promise ❤️

Yes, #MonthOfArXiv is A LOT OF WORK, but I do recommend it to everyone that needs a little extrinsic motivation to keep up with recent literature. 🔥

It made me so happy to talk to my supervisor today and point out something that I had read in the last couple of days while actually REALLY understanding what the paper was about (because I had to read it in detail for the thread, win-win 🙌🏻).

Do recommend! 🤭

@phdstudents

Is this really me catching up to TODAY?

For the fifth paper of my #MonthOfArXiv (IT’S FROM TODAY!!), I chose a paper studying the planet MASCARA-4 b. If you are intrigued by that name, I recommend reading yesterday’s thread about MASCARA-1 b.

The title of the paper is “Detection of rubidium and samarium in the atmosphere of the ultra-hot Jupiter MASCARA-4 b” and was written by Jiang and collaborators.

Let’s check it out! 👇🏼🧵

For the forth paper of my #MonthOfArXiv (catching up from yesterday again), I chose a paper studying the upper atmospheres of a couplet of planets.

The title of the paper is “Characterisation of the upper atmospheres of HAT-P-32 b, WASP-69 b, GJ 1214 b, and WASP-76 b through their He I triplet absorption” and was written by Lampón and collaborators.

Let’s dive right into it! 👇🏼🧵

Paper No. 2 for today!

For the third paper of my #MonthOfArXiv I have chosen a paper from my own field. I hope that I can give you a personal flavour, because it is about an important mechanism. Hooked? Follow me! 👇🏼🧵

The title of the paper is “The PEPSI Exoplanet Transit Survey. III: The detection of Fe I, Cr I and Ti I in the atmosphere of MASCARA-1 b through high-resolution emission spectroscopy” and was written by Scandariato et al.

For the second paper in my #MonthOfArXiv, I read a paper that is again not really in my field, but I just love reading about Hycean Worlds, maybe because I can somehow picture them? 🤔

The title of today’s first paper (originally from Friday) is “The Runaway Greenhouse Effect on Hycean Worlds” and it is written by Hamish Innes, Shang-Min Tsai and Raymond T. Pierrehumbert.

What is a Hycean world, you wonder? Well, let’s find out together! 👇🏼🧵

The main takeaway is that causal definitions of algorithmic fairness lead to Pareto-dominated policies.

In plain English, this means: whatever your preference (more efficiency or more equity) there will always be another strategy to is more satisfying to everyone involved.

Or, even simpler: this is bad for everyone involved.

#EthicalAI #MonthOfArxiv #machineLearning

How to fix this? The consequentialist framework (CF) to algorithmic fairness foregrounds the results of decisions, rather than properties of the prediction.

One starts by identifying the utility of different possible outcomes, eg efficiency and equity. Optimal decision policies can be derived with Linear Programming that uses stakeholder preferences.

This approach has advantages over static experimental designs (eg randomized trials)

#EthicalAI #MonthOfArxiv #AlgorithmicFairness

"Learning to Be Fair: A Consequentialist Approach to Equitable Decision-Making"

While designing fair machine learning systems an approach could be to ensure parity in error rates across race, gender etc. It turns out to really matter how we define this statistically: some strategies might sound fair but ignore downstream effects and can cause unexpected harm to the very groups we try to protect.

An interesting approach towards implementiny critical thinking is to use philosophical strategies for prompt engineering. For example, the maieutic method:

"The term “maieutic” comes from the Greek word “maieutikos,” which means midwife. The method of maieutics is based on the idea that the teacher’s role is to help the student give birth to their own understanding of a subject, rather than to impart knowledge directly."

#chatgpt #PromptEngineering #ethicalAI #MonthOfArxiv

In general, the goal is to give the model perception, attention/awareness, emotional and ethical reasoning, critical and exploratory thinking.

All of these are realised with a submodular framework:

"CoCoMo consists of four modules: the receptor, unconsciousness, consciousness, and effector modules"

#monthofarxiv #generativeAI #ethicalAI #consciousness #ai

They propose splitting up attention and awareness in the model, which is really interesting:

"Awareness encompasses the full scope of conscious experience, while attention is a specific cognitive process that enables focus on certain stimuli or sources of information. In CoCoMo, an event that is being aware of can be placed in a low-priority task/job pool, awaiting a central scheduler to prioritize and pay attention to it. "

#MonthOfArxiv #ethicalai #consciousness

"Sigmund Freud was among the first to propose a model of the mind that incorporates both conscious and unconscious processes"

The idea of modelling multiple agents, centers of activity, areas, just as we have conscious, subconscious and unconscious processes is really appealing to me.

#MonthOfArxiv #consciousness

A definition of consciousness:

The Integrated Information Theory (IIT) proposes that consciousness arises from the integration of information across different brain areas, and that the complexity of an organism’s consciousness is determined by the amount of integrated information it can process.

#MonthOfArxiv #ethicalai #consciouness

My first #MonthOfArxiv !

This paper describes a model for creating AI agents that combine knowledge with compassion.

AI is vulnerable to bias, toxicity and reliability issues; the idea is that by modelling emotional intelligence, impulse regulation and ethical reflection it should be possible to create generative AI that avoids these issues.

So let's get this party started!

For the first paper in my #MonthOfArXiv, I decided to go a little wild: I picked a paper that isn't really in my research field. Why not start this challenge with a real challenge?

The title of the paper is "G 68-34: A Double-Lined M-Dwarf Eclipsing Binary in a Hierarchical Triple System" and it is written by Emily K. Pass and David Charbonneau.

A double-lined M-dw... what? Well, let's get into this! 👇🏼🧵

#challenge #PaperThread

I have seen a few fellow researchers doing the #MonthOfArXiv on the bird app and I am really intrigued to try it.

The goal is to read and write a thread about a #paper on #arXiV every day (where there are new papers ofc). Anyone up for a #challenge together?
