WebGPU is the new GPU API that available in browser. It’s one of the only 2 APIs that currently available to access the GPU from browser (the other is WebGL).
WebGPU is the successor to WebGL, providing better compatibility with modern GPUs, support for general-purpose GPU computations, faster operations, and access to more advanced GPU features.
WebGL基本问题 WebGL has some fundamental issues that needed addressing:
Since WebGL’s release, a new generation of native GPU APIs have appeared — the most popular being Microsoft’s Direct3D 12, Apple’s Metal, and The Khronos Group’s Vulkan — which provide a multitude of new features.
目前有三种主流的Subword分词算法，分别是Byte Pair Encoding (BPE), WordPiece和Unigram Language Model
Back in the ancient times, before 2013, we usually encoded basic unigram tokens using simple 1’s and 0’s in a process called One-Hot encoding. word2vec improved things by expanding these 1’s and 0’s into full vectors (aka word embeddings). BERT improved things further by using transformers and self-attention heads to create full contextual sentence embeddings.
传统的词编码：one-hot 分布式词编码：word embedding word2vec CBOW模型是在已知当前词上下文context的前提下预测当前词w(t)，类似阅读理解中的完形填空； 而Skip-Gram模型恰恰相反，是在已知当前词w(t)的前提下，预测上下文context。

CAN消息总线格式 DBC格式 BO_ 500 IO_DEBUG: 4 IO SG_ IO_DEBUG_test_unsigned : 0|8@1+ (1,0) [0|0] "" DBG 说明：
The message name is IO_DEBUG and MID is 500 (decimal), and the length is 4 bytes (though we only need 1 for 8-bit signal) The sender is IO 0|8: The unsigned signal starts at bit position 0, and the size of this signal is 8 (1,0): The scale and offset (discussed later) [0|0]: Min and Max is not defined (discussed later) ””: There are no units (it could be, for instance “inches”) @1+: Defines that the signal is little-endian, and unsigned: Never change this!
three main use cases for metadata repositories: Finding data assets For example, a data architect may want to know which tables in which databases contain a Customer_ID.
Tracking lineage (provenance) Many regulations require enterprises to document the lineage of data assets—in other words, where the data for those assets came from and how it was generated or transformed.
Impact analysis If developers are making changes in a complex ecosystem, there is always a dan‐ ger of breaking something.
