The transformer neural network was a revolution in the field of machine learning. Let’s have look at the reasons why transformer architecture is needed: 1. RNN suffers from the vanishing gradient problemwhich causes long-term memory loss. RNN does the processing of text sequentially, which means if there is a long sentence like- ‘XYZ went to France...
Positional Encoding
Transformers lack an inherent understanding of the sequential order of elements, positional encodings are incorporated into the input embeddings. These encodings serve to convey information about the specific positions of tokens within the sequence.
Position-wise Feedforward Networks
The feedforward network consists if a fully connected layer for followed by non-linear activation function, such as Rectified Linear Unit (ReLU). The model captures and process features at different position in the sequence. These networks in both the encoder and decoder operate independently on each position.
Attention Mechanism
Theattention mechanismin transformers employs a scaled dot-product approach, where the computation involves scaled dot products between the query, key, and value vectors. This produces weighted values that are then summed to yield the attention output. To enhance the model’s capacity to capture diverse relationships within the input, the multi-head attention mechanism is introduced. This involves applying the attention mechanism multiple times concurrently, each with distinct learned linear p...
Some of the applications of transformers are: 1. Transformers is used for NLP tasks like, machine translation, text summarization, name entity recognitionand sentimental analysis. 2. Another application is speech recognition system, where audio signals are processed to provide transcribed text. 3. The application transformers in only limited to NLP...
