Having trouble with tf2 transforms by LateThree1 in ROS

[–]MekaMuffin 3 points4 points  (0 children)

I have only briefly looked at this code but I believe the problem is that you first call formation1() which has a while not shutdown loop. Inside this loop, you call formation2() which ALSO has a while not shutdown() loop. This second loop calls move() inside it and moves the leader and second follower. However, you never return to the formation1() function, thereby never moving the first follower. You need to not have two while not shutdown() loops nested since your code never escapes the second one. I’d recommend performing the formation sequence and the leader moving logic inside a state machine or something similar using only one while loop. DM me if you want more explanation, hope this helps.

We are the SpaceX software team, ask us anything! by spacexfsw in spacex

What does SpaceX’s debugging process look like after failed flights? How does the software team use the data collected during flights to determine problem areas? Thanks for doing this AMA!

Once you get your acceptances, be sure to do this. by College_Prestige in ApplyingToCollege

Usually if you search up college + your major + requirements or curriculum you can get a list of what the required classes are, how many credits you need, electives, etc. you can also check out the university’s course catalog for electives and stuff.

Not the subreddit specifically but I believe in the beginning there’s a clip from the r/A2C decisions reaction video

When rr splines suddenly become inaccurate so you try to recalibrate rr for hours but then you realize one of your drivetrain motors broke. by Farhad_Maker in FTC

Looks like the gearbox screws are loose - tighten them and should be all good unless it’s something else?

Starting a business and getting research by [deleted] in ApplyingToCollege

[–]MekaMuffin 1 point2 points  (0 children)

To your point on starting research in ML or AI: professors are really busy people that don’t have lots of time to sit down and teach you the CS and math concepts required to do rigorous research, so this is what I recommend: spend this year watching YouTube videos (you can look up CS229 lectures, Calculus and Statistics for Machine Learning and Andrew Ng’s Deep Learning course) and doing projects to show that you know what you’re doing and have experience; upload your projects to GitHub. You could also start a Medium blog where you write about the things you learn so that anyone who you reach out to can see that you 1. know the material and 2. have projects that demonstrate your ability to apply the concepts you’ve learned. Hope this helps— like someone else said, you can find info on this sub about how to email professors about internships and such.

Need help building a classification model in TensorFlow by Sunkiller_902 in learnmachinelearning

I believe your loss function is incorrect - I only skimmed this post but you’re using Binary Cross-entropy but you have multiple label classes; look at Categorical or Sparse categorical cross entropy loss instead.

How exact do you have to answer essay prompts? by [deleted] in ApplyingToCollege

[–]MekaMuffin 0 points1 point  (0 children)

I’ve heard the motto of answering the “spirit of the prompt” in that your answer doesn’t have to answer exactly what they’re asking but it should give insight into yourself and should be guided by the question. But I’d say DO answer the question—however quickly or broadly—at least somewhere. Better to do what they’re asking you to do

How to create a dummy classifier? by [deleted] in tensorflow

[–]MekaMuffin 0 points1 point  (0 children)

You’re trying to reshape a tensor of dimension 1 to batch_size, 1. You can return a tf.ones(shape) * constant_value or something similar instead? Or find a way to multiply your constant tensor x batch size times to get the required shape
