Which method finds better neural nets — slow search, random tries, or evolutionary picks?
We looked at three simple ways to hunt for good neural network designs and saw clear differences.
Grid Search checks many fixed options and can be slow, but sometimes it finds steady results.
Random Search just tries many random choices and often finds good settings faster than expected.
And Genetic Algorithm mixes and mutates designs over time, it can discover clever designs but needs more runs to shine.
The tests were run on a common image dataset, so results reflect real tasks people care about.
What matters most is the trade off between time and final accuracy; some methods run quick but give okay models, others take longer and sometimes win on quality.
If you want quick answers, pick random; if you have time to wait, try the evolutionary route; if you like thoroughness, grid might suit you.
Each way has pros and cons, so choose what fits your goal and compute budget, and try different ways, because results can surprise you.
