. BIDIRECTIONAL definition: 1. We have also discussed common practices for training and evaluating the model, as well as best practices for hyperparameter tuning and regularization. Telephone lines are, by operational requirements, bidirectional. Whether you’re a teacher or a learner, Vocabulary. view(seq_len, batch, num_directions, hidden_size). Guess everything is alright either. Bidirectional definition: Moving or operating in two usually opposite directions. Meaning, pronunciation, picture, example sentences, grammar, usage notes, synonyms and more. lstm = nn. super(BiLSTM_Attention, self). See examples of bidirectional used in a sentence. com can put you or your class on the path to systematic vocabulary improvement. Embedding(vocab_size, embedding_dim) self. Moving or operating in two usually opposite directions: bidirectional data flow. Jul 23, 2025 · The integration of attention mechanisms with Bidirectional Long Short-Term Memory (Bi-LSTM) networks has become a popular approach in various natural language processing (NLP) tasks. The attention mechanism allows the model to focus on specific parts of the input sequence, enhancing its ability to capture relevant information. going in two directions or having parts that go in two directions, usually opposite from each…. Definition of bidirectional adjective in Oxford Advanced Learner's Dictionary. A bidirectional device accommodates signals traveling either direction though a single channel. bi′di·rec′tion·al′i·ty (-năl′ĭ-tē) n. Learn more. The proposed architecture is called attention-based bidirectional long short-term memory with convolution layer (AC-BiLSTM). Example of splitting the output layers when batch_first=False: output. Linear(n_hidden * 2, num_classes) # lstm_output : [batch_size, n_step, n_hidden * num_directions (=2)], F matrix def attention_net(self, lstm_output, final_state): Apr 14, 2019 · In order to solve the above problems, a novel and unified architecture which contains a bidirectional LSTM (BiLSTM), attention mechanism and the convolutional layer is proposed in this paper. BIDIRECTIONAL definition: capable of reacting or functioning in two, usually opposite, directions. Triodes for alternating current are bidirectional and so current can flow through them in either direction. LSTM(embedding_dim, n_hidden, bidirectional=True) self. Nov 13, 2025 · Conclusion In this blog, we have explored the fundamental concepts of Bidirectional LSTM and attention mechanisms and how to implement them in PyTorch. Jul 9, 2023 · Afterwards started to implement the LSTM part and, If I understood it right, the output shape should be (batch_size, 256) (because it's bidirectional, 1 layer and 128 units). embedding = nn. out = nn. This article provides a comprehensive guide on how to add an For bidirectional LSTMs, forward and backward are directions 0 and 1 respectively. __init__() self. But what I am trying to figure out is how to implement that attention layer.
