StockSeqCompare

Head-to-head benchmark of six PyTorch sequence architectures — LSTM, GRU, Transformer, BiLSTM, LSTM+Attention, CNN-LSTM — on next-day stock return prediction. A naive OHLCV baseline isolates raw architecture performance, while a second causal, look-ahead-free feature-engineered pipeline backtests each model as a long/short strategy against buy-and-hold.
