CNTK Python 如何将多个特征传递到模型中

Question

我得到如下数据文件：

|HandPercentage 0.5958  |NoOfPlayersInPlay 2    |HeroPosition 5 |Pot 1.00   |Player0 0 0.00 100.00  |Player1 1 0.00 100.00  |Player2 2 0.00 100.00  |Player3 3 0.00 100.00  |Player4 4 1.00 99.00   |Player5 5 0.00 100.00  |Action 0 0 1

我在 python 中使用 CNTK，我的读者如下：

def create_reader(path):
    streams = CTFDeserializer(path, StreamDefs(
        HandPercentage = StreamDef(field='HandPercentage', shape=input_dim,   is_sparse=False),
        NoOfPlayersInPlay = StreamDef(field='NoOfPlayersInPlay', shape=input_dim,   is_sparse=False),
        HeroPosition = StreamDef(field='HeroPosition', shape=input_dim,   is_sparse=False),
        Pot = StreamDef(field='Pot', shape=input_dim,   is_sparse=False),
        Player0 = StreamDef(field='Player0', shape=player_dim,   is_sparse=False),
        Player1 = StreamDef(field='Player1', shape=player_dim,   is_sparse=False),
        Player2 = StreamDef(field='Player2', shape=player_dim,   is_sparse=False),
        Player3 = StreamDef(field='Player3', shape=player_dim,   is_sparse=False),
        Player4 = StreamDef(field='Player4', shape=player_dim,   is_sparse=False),
        Player5 = StreamDef(field='Player5', shape=player_dim,   is_sparse=False),
        labels  = StreamDef(field='Action', shape=label_dim,   is_sparse=False)))
    return MinibatchSource(streams)

当我需要训练我的模型时，我需要将所有节点放在一起，我创建一个如下所示的 input_map：

input_dim = 1
player_dim = 3
label_dim = 3

....

HandPercentage = Input(input_dim,  is_sparse=False)
NoOfPlayersInPlay = Input(input_dim,  is_sparse=False)
HeroPosition = Input(input_dim,  is_sparse=False)
Pot = Input(input_dim,  is_sparse=False)
Player0 = Input(player_dim,  is_sparse=False)
Player1 = Input(player_dim,  is_sparse=False)
Player2 = Input(player_dim,  is_sparse=False)
Player3 = Input(player_dim,  is_sparse=False)
Player4 = Input(player_dim,  is_sparse=False)
Player5 = Input(player_dim,  is_sparse=False)
labels = Input(label_dim, is_sparse=False)  # TODO: make sparse once it works

input_map = {
    HandPercentage : reader.streams.HandPercentage,
    NoOfPlayersInPlay : reader.streams.NoOfPlayersInPlay,
    HeroPosition : reader.streams.HeroPosition,
    Pot : reader.streams.Pot,
    Player0 : reader.streams.Player0,
    Player1 : reader.streams.Player1,
    Player2 : reader.streams.Player2,
    Player3 : reader.streams.Player3,
    Player4 : reader.streams.Player4,
    Player5 : reader.streams.Player5,
    labels : reader.streams.labels
}

我想将它们连接在一起，然后将它们传递到我的火车模型中：

inputs = []
inputs.append(HandPercentage)
inputs.append(NoOfPlayersInPlay)
inputs.append(HeroPosition)
inputs.append(Pot)
inputs.append(Player0)
inputs.append(Player1)
inputs.append(Player2)
inputs.append(Player3)
inputs.append(Player4)
inputs.append(Player5)

features = inputs

# apply model to input
z = model(features)

有谁知道我怎么能在 BrainScript 中做类似 RowStack 的事情？

Answer 1

由于您拥有所有密集特征，如果可能的话，为什么不将所有输入连接到一个平面特征向量中以开始生成输入文件。
