## Features

- This toolbox consists of multiple modules including the following :
    - [Search Searcher module](tinynas/searchers/README.md)
    - [Search Strategy module](tinynas/strategy/README.md)
    - [Models Definition module](tinynas/models/README.md)
    - [Score module](tinynas/scores/README.md)
    - [Search Space module](tinynas/spaces/README.md)
    - [Budgets module](tinynas/budgets/README.md)
    - [Latency Module](tinynas/latency/op_profiler/README.md)
    - [Population module](tinynas/evolutions/README.md)

It manages these modules with the help of [ModelScope](https://github.com/modelscope/modelscope) Registry and Configuration mechanism.

- The `Searcher` is defined to be responsible for building and completing the entire search process. Through the combination of these modules and the corresponding configuration files, we can complete backbone search for different tasks (such as classification, detection, etc.) under different budget constraints (such as the number of parameters, FLOPs, delay, etc.).

- Currently supported tasks: For each task, we provide several sample configurations and scripts as follows to help you get started quickly.

- `Classification`：Please Refer to [Search Space](tinynas/spaces/space_k1kxk1.py) and [Config](configs/classification/R50_FLOPs.py)
    - `Detection`：Please Refer to [Search Space](tinynas/spaces/space_k1kx.py) and [Config](configs/detection/R50_FLOPs.py)
    - `Quantization`: Please Refer to [Search Space](tinynas/spaces/space_quant_k1dwk1.py) and [Config](configs/quant/Mixed_7d0G.py)
