## Dataset Description |
|
|
|
This dataset includes 8 episodes of pong-v4 environment. The expert policy is EfficientZero, which is able to generate MCTS hidden states. |
|
|
|
## Dataset Structure |
|
### Data Instances |
|
A data point comprises tuples of sequences of (observations, actions, hidden_states): |
|
``` |
|
{ |
|
"obs":datasets.Array3D(), |
|
"actions":int, |
|
"hidden_state":datasets.Array3D(), |
|
} |
|
``` |
|
## Source Data |
|
|
|
### Data Fields |
|
|
|
- `obs`: An Array3D containing observations from 8 trajectories of an evaluated agent. The data type is uint8 and each value is in 0 to 255. |
|
- `actions`: An integer containing actions from 8 trajectories of an evaluated agent. This value is from 0 to 5. |
|
- `hidden_state`: An Array3D containing corresponding hidden states generated by EfficientZero, from 8 trajectories of an evaluated agent. The data type is float32. |
|
|
|
### Data Splits |
|
There is only a training set for this dataset, as evaluation is undertaken by interacting with a simulator. |
|
|
|
## Data Creation |
|
|
|
### Curation Rationale |
|
|
|
- This dataset includes expert data generated by EfficientZero. Since it contains hidden states for each observation, it is suitable for Imitation Learning methods that learn from a sequence like [Procedure Cloning (PC)](https://arxiv.org/abs/2205.10816). |
|
### Source Data |
|
#### Initial Data Collection and Normalization |
|
- This dataset is collected by EfficientZero policy. |
|
- Each return of 8 episodes is 20. |
|
- No normalization is previously applied ( i.e. each value of observation is a uint8 scalar in [0, 255] ) |
|
#### Who are the source language producers? |
|
- [@kxzxvbk](https://huggingface.co/kxzxvbk) |
|
|
|
#### Annotations |
|
- The format of observation picture is [H, W, C], where the channel dimension is the last dimension of the tensor. |
|
|
|
## Considerations for Using the Data |
|
|
|
### Social Impact of Dataset |
|
|
|
- This dataset can be used for Imitation Learning, especially for algorithms that learn from a sequence. |
|
- Very few dataset is open-sourced currently for MCTS based policy. |
|
- This dataset can potentially promote the research for sequence based imitation learning algorithms. |
|
