- The document discusses estimating structured vector autoregressive (VAR) models from time series data.
- A VAR model of order d is defined as xt = A1xt-1 + ... + Adxt-d + εt, where xt is a p-dimensional time series, Ak are parameter matrices, and εt is noise.
- The document proposes regularizing the VAR model estimation problem to promote structured sparsity in the parameter matrices Ak. This involves transforming the model into a linear regression form and applying group lasso or fused lasso regularization.

GPUサーバを搭載すると
空調性能(8kW)がボトルネック
DGX1だと4台搭載できるかどうか
12Uしか使えない
37Uがデッドスペース
49Uラック
NVIDIA DGX1

IDCFでは
通常のCPUクラウドサーバとGPUクラウドサーバ
を混載することでスペースを有効活用
GPUサーバ 16U(2Ux8台)
CPUサーバ 16U(1Ux16台)
NWスイッチ 7U
GPUの熱を逃がすためにラックの上部に設置するとかも考慮してたりします。。
