Hi Peter, thanks for the AMA. Are there any benefits to converting from a green card to citizenship, in the context of employment? Access to some government jobs is the only thing I can think of. Can green cards be extended every time they

Amazing idea and execution. If you don’t mind revealing, can you describe the ML components in the background? Model, data trained on, etc.? Thanks and good luck!

Please keep in mind that the tips/tools/techniques that people list are highly subjective and may not be applicable everywhere. I realized this from my own experience (worked at two startups in the past, and now at BigCo): * Glass

I did. Once I joined the companies that did not openly answer my questions during interviews (about finances, strike price, etc.), I ended up realizing all the negatives/problems of the companies from the inside. Then on, I had only tw

So true! I've interviewed with several startups (about 50-60) in the past, over the course of 5 years. I had offers from most of them, while some of them rejected me after the interviews (for whatever reasons they had). Your comment is

Some good points by others on this post. I want to focus on something more latent. Are you sure there are no other distractions in your life? Try to find out if there is something deeper than surface level that is bothering you. Such distra

Yes, the primary utility is to understand how discriminative your features are. There is no meaning of what each face represents. Checkout the Chernoff Fish demo posted below by the user meagher here: https://news.ycombinator.com

I agree. I don't think this isn't any more revealing. Just a different way of visualizing. And there is also the drawback of a whole new interpretation when you re-map your input features to Chernoff facial features.

I worked with Chernoff faces long time back and love how this is an interesting way to visualize how discriminative your features are. The idea is that you take features of your dataset, and use those to represent a face. Say for example, y

I lean towards what Velodyne is saying in this situation. I have been working with LiDAR systems for over 4 years of which the last 1.5 years have been towards building autonomous driving vehicles. When I saw the videos, I was truly baffled

Great question. At least in our algorithms we do this - to adjust the driving speed based on the conditions (e.g., visibility or perception capabilities). At the end of the day, you can drive only as fast as your perception capabilities. A

I have the same questions as well. But my best guess is that they probably have permission to drive at non-highway speeds at late nights/early mornings (which is when this accident occurred, at 10 PM). My first reaction when I watche

This looks great! Nice work. I have a suggestion: Could you highlight a path when an edge is clicked on? I guess the clicking on the nodes can link to their wiki pages.

Did any of you succeed in asking such questions to companies (ML/AL or not) and ended up receiving reasonable responses to your questions? My experiences have never been great when asking such loaded questions. To be clear, I interview

You surely can, but it could be very difficult. Publishing research without any affiliation could be difficult because of various reasons beyond your control. Having an advisor or a team can significantly boost your publication quality.
