c++ - Which is faster: Stack allocation or Heap allocation - Stack Overflow
On my machine, using g++ 3.4.4 on Windows, I get "0 clock ticks" for both stack and heap allocation for anything less than 100000 allocations, and even then I get "0 clock ticks" for stack allocation and "15 clock ticks" for heap allocation. When I measure 10,000,000 allocations, stack allocation takes 31 clock ticks and heap allocation takes 1562 clock ticks.

so maybe around 100x difference? what does that work out to in terms of total workload?

Recent work shows that dynamic memory allocation consumes nearly 7% of all cycles in Google datacenters.

That's not too bad actually. Seems like I shouldn't worry about shifting from heap to stack/globals unless profiling says it's important, particularly for non-oly stuff.

edit: Actually, factor x100 for 7% is pretty high, could be increase constant factor by almost an order of magnitude.

classification - ImageNet: what is top-1 and top-5 error rate? - Cross Validated
Now, in the case of top-1 score, you check if the top class (the one having the highest probability) is the same as the target label.

In the case of top-5 score, you check if the target label is one of your top 5 predictions (the 5 ones with the highest probabilities).

Basic Error Rates
This page describes human error rates in a variety of contexts.

Most of the error rates are for mechanical errors. A good general figure for mechanical error rates appears to be about 0.5%.

Of course the denominator differs across studies. However only fairly simple actions are used in the denominator.

The Klemmer and Snyder study shows that much lower error rates are possible--in this case for people whose job consisted almost entirely of data entry.

The error rate for more complex logic errors is about 5%, based primarily on data on other pages, especially the program development page.
