for you to start.
There's some good discussion there as well as links to papers.

Hi,

, and L2 norm just means squared length. It's
not something you would write an ML paper on any more than what the
vector dot product is. Are you asking something else?

Hi all,
I've had smashing success with Spark 0.7.x with this code, and this same
code on Spark 0.8.0 using a smaller data set. However, when I try to use a
larger data set, some strange behavior occurs.
I'm trying to do L2 regularization with Logistic Regression using the new
ML Lib.

Anyone have any ideas based on the stack trace?
Thanks

I am sure you have already checked this, any chance the classpath has
v 0.7.x jars in it?

Hi,
I just updated my imports and tried to run my app using Spark 0.8, but it
breaks. The AMI's spark-shell says it's 0.7.3 or thereabouts, which is
what my app previously used. What is the official, step-by-step solution
to using Spark 0.8 on EC2

Hi,
The docs say that we should be careful to increase spark.akka.threads
when our cluster size increases. Is there a rule of thumb for how much we
should increase it? For instance
to all worker nodes
multiple times. Then the broadcast variable is a good choice

Shangyu,
Thanks for the tip re: the flag! Maybe the broadcast variable is only
for complex data structures?

Will that cause a hit to performance or cause the program to crash?
Thanks
Are there heuristics to check when the scheduler says it is missing
parents and just hangs?
