[Apache TVM Discuss] [Questions] Question about the "pack-sum" loss of XGBoost in Ansor

2021-07-28 Thread Chenfan via Apache TVM Discuss
In my mind, this part in Ansor is almost similar to AutoTVM, I'm not sure if this has been explained in these two papers. Recently there's also another work about the cost model of Ansor: https://openreview.net/forum?id=aIfp8kLuvc9 cc @merrymercy --- [Visit Topic](https://discuss.tvm.ap

[Apache TVM Discuss] [Questions] Question about the "pack-sum" loss of XGBoost in Ansor

2021-07-28 Thread Tang Shizhi via Apache TVM Discuss
Ansor uses its XGBoost based cost model in an advanced manner. Each prediction is a sum of several XGBoost calls. To train the model, a "pack-sum" loss is used. Training a cost model in this way seems interesting. Can anyone explain the mechanism in detail? The only thing I got is the source

The compiler output is a tree of `runtime.Module`. DSO-exportable means a `runtime.Module` in that tree whose `type_key` is `c` or `llvm`. TVM links directly against LLVM and invokes the LLVM APIs to generate code. When you call `export_library`, TVM traverses the tree of `runtime.Module`. W
