UnverifiedPCA 是线性降维方法，对于具有非线性流形结构的数据，t-SNE 或 UMAP 等方法往往更为有效76% similarUnverifiedPCA achieves dimensionality reduction by performing eigenvalue decomposition of the covariance matrix (or SVD on the data matrix), and can only encode second-order statistical relationships (linear correlations) among variables, thus inherently only capable of discovering linear manifold structures.63% similarUnverifiedOn-device inference adopts the paradigm of 'data stays, model moves': a pre-trained model is downloaded to the local device, inference is completed on the device's NPU or GPU, and input data remains within the secure sandbox.58% similarUnverified专家预取（Expert Prefetching）机制在当前层计算时异步预测下一层可能激活的专家并提前通过PCIe传输至GPU显存以隐藏传输延迟56% similarUnverifiedThe model training section of this project organizes full-pipeline resources covering pre-training, fine-tuning (SFT/RLHF/DPO), and efficient inference deployment.55% similar
