edhu2017··on Q-learning is not yet scalable
Care to elaborate how AZ/MZ are not model based? MuZero learns a transition function. AZ uses a known transition model to do planning, but I would still say that's model-based RL.
edhu2017··on Ask HN: What interesting problems are you working on?
Data-driven robot control methods for solving furniture assembly.

It's an interesting problem, requiring both dexterous manipulation and long-term planning. It's also compositional, so I believe some form of hierarchical control and planning can solve it.

edhu2017··on IKEA Furniture Assembly Environment
Hey all, I'm one of the authors of the environment. I'm excited to see what researchers will come up with to tackle the furniture assembly problem. Let me know if you have any questions or comments.
edhu2017··on ‘A toxic culture of overwork’: The graduate student mental health crisis
We don't plan too many meetings. Once a week for a lab wide meeting. Most of these meetings are casual and just discussions between cliques of phd students on specific topics.
edhu2017··on ‘A toxic culture of overwork’: The graduate student mental health crisis
Being in the lab helps me focus on my thinking. I also discuss my current thinking and problems with my peers for critique, and I can do the same for them. I'm more conditioned to do research, and my mind wanders less in the lab.

However, I do agree that having free time and being away from the lab is important to get a fresh view of things.

Disclaimer: Our field is extremely competitive (deep learning) and other labs may have better working styles depending on their lab size and member composition.

My lab's workload on average is 8 - 12 hours a day for 6-7 days a week, ramping up even more closer to deadlines. That being said, a lot of this time (50% or more) is for thinking and discussing. This schedule, while hard, seems to be effective for publishing in good conferences.

This is AI snakeoil.
edhu2017··on Why Most Published Research Findings Are False (2005)
Agreed, reimplementation is pretty good for students to learn. Our lab requires everybody to work on an implementation project
edhu2017··on Federated Learning
definitely has been done before.
edhu2017··on Python Fire – Generates CLIs from any Python object
Good question, for me I programatically generate a folder with the hyperparameter key - values in the name and store the checkpoints under it. As you can imagine, it can get out of control quickly if not managed well, but it works for 1-3 person projects. For anything more large scale or organized, I would recommend looking into Comet ML which lets you query and filter your experiments by hyperparameter ranges instead of manually looking at folder names.
edhu2017··on Python Fire – Generates CLIs from any Python object
seems great for my reinforcement learning models. instead of parsing my hyperparameters through the tensorflow cli API and editing the training file a line at a time to take in an additional hyperparameter, I can just directly set them through the cli with fire.
edhu2017··on Taking Tesla Private
I think it's a great move. Prevents short term greedy shareholder strategies.
edhu2017··on Building a Kickass Portfolio
Depends on how simple you want to get. If literally displaying text once in a while, you don't even need jekyll. If you are a blog writer, want some sort of templating / reusable snippets, or want cool themes then jekyll is good.

fight on! these projects are interesting but i'm still a student
edhu2017··on Macbook eGPU Redux: Sticking a GTX 1080 in an AKiTiO Thunder2
I see, but I think for areas like Reinforcement Learning or sequence models though eGPUs would be significantly slower since you have to constantly shuttle new data into the GPU from your computer.

edhu2017··on Macbook eGPU Redux: Sticking a GTX 1080 in an AKiTiO Thunder2
I heard the eGPU gets throttled memory wise because there are less pcie lanes. does this have a big impact on ML performance?
edhu2017··on Efficient Methods and Hardware for Deep Learning [pdf]
Pruning, Weight Sharing and Quantization are commonly used techniques and can be done in tf.
edhu2017··on Live tracking of Amtrak trains
somebody with conjoined fingers!
edhu2017··on Facebook AI Research Expands with New Academic Collaborations
Total compensation: Definitely a wide range, but a few hundred K would be the median. Recruiting: one of my labmates flat out refused to do algorithmic interviews for a research position and the company still gave him an offer. Your projects, papers, and ability to demonstrate your understanding of research topics are far more important then your ability to solve a small, defined problem in 45 minutes.

most of the images won't load for me.

whats the comparison between hammerjs and this?
edhu2017··on Blot – a blogging platform with no interface
would like to see mathjax support
edhu2017··on Microsoft has sunk a data centre in the sea to investigate energy efficiency
It's not, because no one would use a coin with such imbalance in mining power. It would be all around more efficient for people to just donate to scientists.
edhu2017··on AI at Google: our principles
From my observations in my college, Google is starting to become the new "Microsoft". It is still seen as well paying, and nerdy but it is no longer new and exciting. Facebook is taking over Google's spot as the well established but still exciting tech company, while Airbnb seems to be taking FB's spot as the new and exciting tech company.
edhu2017··on Microsoft has sunk a data centre in the sea to investigate energy efficiency
Here's the problem for me. These mining operations can be exploited to an extreme. Any scientist or professor with knowledge in protein representations will have an unfair advantage over normal miners. This gap will be even larger than the hashpower gaps we see between ASICs and "normal" miners in bitcoin, litecoin, etc because scientists will have access to not only hardware but also extremely specific domain knowledge.
edhu2017··on TDM: From Model-Free to Model-Based Deep Reinforcement Learning
How is the distance getting estimated? Like another comment said, if a good distance estimator is provided this simplifies the task. Is there a baseline that uses distance in its input as well?
edhu2017··on Evolved Policy Gradients
"EPG takes a step toward agents that are not blank slates but instead know what it means to make progress on a new task, by having experienced making progress on similar tasks in the past." Can someone explain to me how they take a step? It seems like they just use random search define a loss function for the sub-policy to optimize against. Is it because the loss function is "learned" over the sequence of actions, making it adaptive?
edhu2017··on OpenSimpleLidar
As somebody with software engineering experience but little hardware experience, how do I get started with building my own Lidar? I notice he provides STL files for base plates and a component list https://hackaday.io/project/20628/components. Still not too sure how to start though.
