How general/efficient are these AD systems ? New ops in tensorflow seem to be oriented towards forward-mode AD rather than reverse-mode (for which one needs a pull back op on a dual).

Do you know if CompNeuro models have been trained to do things interesting to CS folk ?

This is probably the only project which goes about building a backplate from household tools, rather than having it milled.

It should be noted that things like momentum etc in DNN training are inspired directly from Nesterov, and apparently work very well.

It's probably (n^3 * n^2) vs (n^2 * n^2) , and not cubic vs linear as was stated, where (n = 1/h).

Nesterov's method attains super-linear convergence on Convex functions. They don't really (if I remember right) work otherwise; but then this is okay, since Convex problems are really the only ones we can solve in poly-time (esp.

AlJazeera has a nice documentary, https://www.youtube.com/watch?v=8OsMdzrxQfA It appears that tusks from African elephants are more valued in China than those from S/S.E Asia. Does anyone know why this is ?

Ah, is this https://github.com/CNugteren/CLBlast ? I was looking at, https://github.com/uncomplicate/neanderthal/blob/master/src/...

Ah, you're right; 5.6 Gflops is for Hawaii. That's doubly impressive. I'll make sure to try your kernel then. Thank you!

by akssri 10y ago
I think it's about 5.6 Tflops. Wow, 3.75 Tflops on Hawaii is very good indeed; I agree this is not something that clBLAS would beat by a wide-margin if at all.

by akssri 10y ago
I found the latest version of clBLAS on Fiji achieves a fantastic ~4 Tflops (on 2^n matrices). NVblas has probably had more resources allocated to it that clBLAS. I'd be positively surprised if the kernels in Neantherdal beat those. Do

by akssri 10y ago
Sweet! Did you consider using AutoGEMM.py from clBLAS instead of a static GEMM kernel ? I was considering using a polyhedral compiler macro (like PPCG), for writing OpenCL kernels in matlisp, but it's not clear how optimal this would b

This of course was political, much as it is today in Tibet. As an aside, I've always found the way in which East Asian Buddhists held firm against cultural invaders, extremely inspiring. In India, there seems to be little other than me

I think he meant Protestantism in particular.

One wonders if this on a meta-philosophical level is related to the acceptance of death in Eastern cultures as just the beginning of another birth. Or may be it's a clever device to make people become attached to life ? Hmm.

Actually there is one such living practice amongst Jains, https://en.wikipedia.org/wiki/Santhara sAkyamuni himself did, and many sAdhus today go to great trouble to become "asaktaH" (non-attached). It's

Rather odd that the course omits decision trees.

These algorithms can't really make much use of Tensorflow.

KF is essentially a symbolic unrolling of a LU decomposition. There is a graphical algorithm which makes all the minutae trivial [1]. [1] https://arxiv.org/pdf/1508.00952.pdf

Fun fact: Symbolics continues to sell 'Macsyma'.
85.
by akssri 11y ago
I think it's also important to note that Macsyma (or atleast Maxima) has a lot of cruft in the code. I actually like Weyl better, even if it hasn't seen active development in ~2 decades. P.S: Maxima actually uses a list-of-lis

What exactly were these 'problems' ?

by akssri 11y ago
Exactly. I think the libertarian way to go would be to limit the role of the Govt. to enable Tax breaks for spouses, and other impersonal things.

by akssri 11y ago
Yeah it's fairly easy to fix this (and you can even do it without unwinding the stack!). There are tons of sbcl global variables which you can tweak on-the-fly.
