Dense Vector 和 Sparse Vector 都是指我们数据的向量表达方式。MetaData 就是元数据。 3 基于 Pinecone 实现语义搜索 安装依赖包 !pip install -qU \ "pinecone-client[grpc]"==2.2.1 \ pinecone-datasets=='0.5.0rc11' \ sentence-transformers==2.2.2 我们跳过数据准备步骤,因为它们非常耗时,直接使用...
Vectors.sparse(size, ret_indices, ret_values).asInstanceOf[SparseVector] } 调用:val w=rand2(4,3) 返回,SparseVector有3个要素函数,size,indices,values. 取某一部分就调用那3个函数。比如:w.size=4,w.indices=(1,2,3,4) def rand3(numRows:Int,numCols:Int,seed:Int):SparseMatrix={ val rand...
We study the sparsity of the solutions to systems of linear Diophantine equations with and without non-negativity constraints. The sparsity of a solution vector is the number of its nonzero entries, which is referred to as the 0-norm of the vector. Our main results are new improved bounds ...

The Compressive Sensing (CS) framework aims to ease the burden on analog-to-digital converters (ADCs) by reducing the sampling rate required to acquire and stably recover sparse signals. Practical ADCs not only sample but also quantize each measurement to a finite number of bits; moreover, ther...
