「/」単位で年、月、日単位で月をTimestamp列に再抽出し、学習データを再加工します.データ検証

モデル定義
class NN(torch.nn.Module):
def __init__(self):
super(NN,self).__init__()
self.linear1 = nn.Linear(7,512,bias=True)
self.linear2 = nn.Linear(512,256,bias=True)
self.linear3 = nn.Linear(256,512,bias=True)
self.linear4 = nn.Linear(512,64,bias=True)
self.linear5 = nn.Linear(64,32,bias=True)
self.linear6 = nn.Linear(32,1,bias=True)
self.relu = nn.ReLU()
torch.nn.init.orthogonal_(self.linear1.weight)
torch.nn.init.orthogonal_(self.linear2.weight)
torch.nn.init.orthogonal_(self.linear3.weight)
torch.nn.init.orthogonal_(self.linear4.weight)
torch.nn.init.orthogonal_(self.linear5.weight)
torch.nn.init.orthogonal_(self.linear6.weight)
def forward(self,x):
out = self.linear1(x)
out = self.relu(out)
out = self.linear2(out)
out = self.relu(out)
out = self.linear3(out)
out = self.relu(out)
out = self.linear4(out)
out = self.relu(out)
out = self.linear5(out)
out = self.relu(out)
out = self.linear6(out)
return out
カラムが追加され、入力が7に設定されます.学習パラメータの設定
model = NN().to(device)
optimizer = optim.Adam(model.parameters(), lr=15e-5)
loss = nn.MSELoss().to(device)
epochs = 1500
model
マッチングを避けるために,epochを1500に減らすと性能が最も高いと決定した.
学習速度も変更しました.
学習モデル
model.train()
plt_los = []
train_total_batch = len(x_train)
for epoch in range(epochs+1) :
avg_cost = 0
model.train()
hypothesis = model(x_train)
cost = loss(hypothesis,y_train)
optimizer.zero_grad()
cost.backward()
optimizer.step()
avg_cost += cost / train_total_batch
plt_los.append([avg_cost.item()])
if epoch%100==0:
print('Epoch : {}, Cost : {}'.format(epoch, avg_cost.item()))
Plot
import matplotlib.pyplot as plt
def plot(loss_list: list, ylim=None, title=None) -> None:
bn = [i[0] for i in loss_list]
plt.figure(figsize=(10, 10))
plt.plot(bn, label='avg_cost')
if ylim:
plt.ylim(ylim)
if title:
plt.title(title)
plt.legend()
plt.grid('on')
plt.show()
plot(plt_los , [0.0, 1.0], title='Loss at Epoch')
print(avg_cost.item())
plot関数を定義してコスト値を可視化し,学習が良好であることを確認した.
予測のエクスポートとコミット
model.eval()
with torch.no_grad():
y_pred = model(x_test)
sample['hash-rate'] = y_pred.cpu().numpy()
sample.to_csv('submit_sample.csv',index=False)
sample
