🚀 Our latest benchmark shows hyperparameter tuning with Optuna hits 0.9617 validation accuracy in just 64.59 seconds! Using Bayesian optimization and the Tree‑structured Parzen Estimator, we ran 100 trials to squeeze out every percent. Dive into the details of the experiment and see how you can apply these tricks to your own models. #HyperparameterTuning #Optuna #BayesianOptimization #ModelOptimization

The Lottery Ticket Hypothesis: finding sparse trainable NNs with 90% less params

Neural network pruning techniques can reduce the parameter counts of trained networks by over 90%, decreasing storage requirements and improving computational performance of inference without compromising accuracy. However, contemporary experience is that the sparse architectures produced by pruning are difficult to train from the start, which would similarly improve training performance. We find that a standard pruning technique naturally uncovers subnetworks whose initializations made them capable of training effectively. Based on these results, we articulate the "lottery ticket hypothesis:" dense, randomly-initialized, feed-forward networks contain subnetworks ("winning tickets") that - when trained in isolation - reach test accuracy comparable to the original network in a similar number of iterations. The winning tickets we find have won the initialization lottery: their connections have initial weights that make training particularly effective. We present an algorithm to identify winning tickets and a series of experiments that support the lottery ticket hypothesis and the importance of these fortuitous initializations. We consistently find winning tickets that are less than 10-20% of the size of several fully-connected and convolutional feed-forward architectures for MNIST and CIFAR10. Above this size, the winning tickets that we find learn faster than the original network and reach higher test accuracy.
Kết quả mới cho thấy Vulkan có thể nhanh hơn CUDA trong chỉ định model. Ví dụ, Ministral3 14B 2512 Q4 có tốc độ tăng lên 4,4 lần khi xử lý prompt. CUDA vẫn là lựa chọn tốt nhất cho đa số trường hợp. #Vulkan #CUDA #ModelOptimization #TechNews #ThiếtKếModel #BảoMật #LenhLem #HóaCván #SốHúc #LinhTụ #ThépKin #TệpMúzeum #CơSốVănHóa

Liệu Kimi K2 Thinking có hoạt động tốt ở mức lượng tử 2.5-3.5 bit/weight không? Được biết model này nguyên bản 4-bit. So sánh với DeepSeek models (8-bit nguyên bản) vẫn hiệu quả ở ~3bpw. Người dùng đã thử Q2_K_XL (3bpw) locally và thấy khá tốt, nhưng chưa thể so sánh với native 4-bit. Thảo luận trên r/LocalLLaMA về hiệu suất quantization. #quantization #AI #machinelearning #KimiK2 #DeepSeek #localAI #modeloptimization #Quantisierung #KünstlicheIntelligenz
🚀 GPT OSS 120B chỉ cần 2 expert vẫn như 4 expert nhưng nhanh x2! Người dùng đạt 40 tps với 2 expert. S<body> có lẽ lại khôngopia?
