creating an informer for forex indicator
Hello,I want to train an informer from scratch but I’m running into the complexity of language barrier.I understand the worlds I read individually but I can’t make sens of the sentences.Or I might be a moron… don’t know.it’s been several weeks that I started this project to see if I could create an indicator for FOREX pairs to help in the decision making but I hit wall after wall.I finally found this forum and hope to lift the fog before my eyes about AI training.Right now I have the dataset ready and need to create the model.As I understand the huggingface docs I need to create a config for my informer model :dataset = Dataset.from_pandas ( data[["open", "high", "low", "close", "open_change", "high_change", "low_change", "close_change", "day_of_year", "day_of_month", "day_of_week", "hour", "minute"]] )

train_test = dataset.train_test_split(test_size=0.2, shuffle=False)
test_val = train_test["test"].train_test_split(test_size=0.5, shuffle=False)

dataset = DatasetDict({
    "train": train_test["train"],
    "test": test_val["train"],
    "val": test_val["test"],
})

#series configuration
history_length = 50
prediction_length = 15

#the lag sequence (I don't really understand what it does)
#my assumption is that it takes history_length datapoints from the set lag
#not sure if it is needed for my application
lags_sequence = get_lags_for_frequency("15min")

config = InformerConfig(
    # number of forcasting
    prediction_length=prediction_length, 
    #data to predict from
    context_length=history_length, 
    #as I understand it, it should be my "day_of_year", "day_of_month", "day_of_week", "hour" and "minute" I might add a position metric relative to the "age" of the datapoint
    num_time_features=5, 
    #should be the rest of my fields "open", "high", "low", "close", "open_change", "high_change", "low_change", "close_change"
    num_dynamic_real_features=8, 
    # complexity of the model
    d_model=128,
    # not sure if these parameters have rules to be followed relative to the input and output size or the size of prediction length
    encoder_layers=4, 
    decoder_layers=4,
    encoder_attention_heads=8,
    decoder_attention_heads=8,
    #since I don't have static or categories I don't think it is worth the trouble to cache or maybe it the inferences are done in real life the 99%of the time series will be the same for each inference
    use_cache=False, 
    sampling_factor=2
)

#this seams straight forward
model = InformerForPrediction(config)
criterion = torch.nn.MSELoss() #I might change it depending on the performances
optimizer = torch.optim.Adam(model.parameters(), lr=1e-3)

#using cuda of course
device = torch.device("cuda:0" if torch.cuda.is_available() else "cpu")

load_train = DataLoader(
    dataset=dataset["train"],
    batch_size=history_length,
    shuffle=False, #keep the timeseries ordered obviously for timedependant data
    num_workers=0, # don't know what it's for ... parallelism maybe
)

#and here I am struggling with yet an other seemingly simple thing
#I can't figure out how to proceed from here... assuming the rest of the code is ok
for epoch in range(10):
    model.train()
    total_loss = 0
    for batch in load_train:
        optimizer.zero_grad()
        print (batch)In the comment I made some points of what I think some things work and needing much clarification.Now for the main question. How can I train my model…I tried to put the batch in video memory but I’m kindly reminded that dict doesn’t have a “to” memberI might need to decompose the batch and send every timeseries in memory individually  but I feel like missing something huge.Can anyone help me ?
