Mish
54 mentions across 5 sources · 36% positive — critical (averaged across 5 sources)
Hacker News, YouTube, Product Hunt, GitHub, Lemmy
What users praise
- • Clear accuracy gains over ReLU and Swish on CIFAR-10 and ImageNet
- • Drop-in replacement — swap activation functions with minimal code changes
- • Self-regularized and non-monotonic, mitigates dying ReLU problem
- • Smooth and unbounded above, improving gradient flow
What frustrates them
- • Can underperform other activations (e.g., ELU) on some architectures
- • Computational overhead from tanh and softplus not fully negligible
- • Correct kaiming gain not documented initially — user had to find it
- • Framework-specific bugs, like TensorFlow 1.14 NameError in RNNs

Praktika
68 mentions across 5 sources · 51% positive — mixed (weighted across 4 sources)
Hacker News, YouTube, Product Hunt, App Store, Lemmy
What users praise
- • Unlimited low-stakes speaking reps without finding or paying a human tutor
- • Non-judging AI tutors help shy learners actually start speaking
- • Named tutors (Raika, Tama, Skye, Camila, Min-Jun) give a sense of continuity
- • Corrections land inside the dialogue instead of interrupting it
What frustrates them
- • AI occasionally marks correct words as wrong and suggests nonsense replacements
- • Pronunciation is reportedly wrong for Chinese and sounds off for Persian
- • Some users hit 'insane latency at every exchange' and high bandwidth requirements
- • Buggy across updates — one user says a fix in one version breaks something else
