BiLSTM
A bidirectional long short-term memory network that captures dependencies before and after a point in a time series by using both past and future context. It is often combined with Transformers for sequence modeling tasks such as financial forecasting.
Timeline (last 90 days)
The quantum recommender and the BiLSTM baseline were benchmarked on the same dataset and the same objective function; the two models achieved comparable performance on the similarity learning task, but the quantum model requires only 47k parameters while the BiLSTM needs 17.8M parameters, the former being about 1/379 of the latter.
When the BiLSTM was constrained to a parameter budget matching the quantum model, its performance dropped significantly, with mean average precision (MAP) falling by 3.63 percentage points.
The short-term BTC/USDT price direction prediction system built by the developer uses a Transformer architecture combined with BiLSTM and cross-attention mechanisms, with about 1.5 million training samples, and the model's direction accuracy is about 60%, a clear improvement over the roughly 52% baseline.
Bidirectional LSTMs scan text simultaneously from left to right and from right to left, concatenating the hidden states from both directions before feeding them into the classification head.
The model uses stacked multi-kernel convolutions to combine sentence-level embeddings into inter-sentence representations, and employs bidirectional LSTM to model long-range dependencies.
