Guys, I've hit a wall with neural networks. Like, why is tuning hyperparameters such a pain? Spent days adjusting learning rate, batch size, layers, etc. Can someone explain how you figure out the best params without wanting to smash your computer??? feel like I'm just randomly trying things.

It got better for me when I started using more systematic approaches. Research papers in your problem area are actually super helpful for hints on hyperparameters. Transfer learning can be a godsend too if you're working with limited data on a problem that's been tackled before.

What's up with the need for hyperparameter tuning anyway? 😂 Can't these networks learn to tune themselves by now? Jokes aside, patience is key. Start with known architectures similar to your problem domain and tweak from there. And use validation sets to stop you from going down the rabbit hole.

Hyperparameters can indeed be frustrating. Consider using automated hyperparameter optimization techniques like Grid Search, Random Search, or Bayesian Optimization. These methods systematically explore the hyperparameter space and can save you a ton of time compared to manual tuning. Remember, there's often a trade-off between the time spent on searching for optimal hyperparameters and the performance gains you might get. Also, check out learning rate schedulers, they can really help.
