Training & Inference
NMT systems are trained with large amounts of parallel data. Think of this data as examples or lessons designed to teach the neural machine. The encoder learns to read input sequences and produce corresponding output sequences. When the NMT system is trained, it’s ready for inference, the process of translating new text data.
Encoder-Decoder
Next, the encoder takes a sentence in the source language and lithuania mobile database transforms it into a representation vector, a sequence of numbers. Then, the decoder transforms those numbers into the corresponding words of the new target language and generates an output sequence.
Attention Mechanism
Experts created attention mechanisms to improve the accuracy and reliability of machine learning translation. You can think of this much like your attention. It allows the encoder and decoder to focus on the most relevant parts of the source text when translating to the target language.
Output Layer
Many different output layers can be used, such as a softmax layer or a linear layer. The output layer of an NMT system is responsible for considering all the possible outputs. It then selects the most likely answer as the final translation.
Evaluation Metrics
Evaluation metrics measure the quality of translations produced by the NMT system. The most popular evaluation metric is the BLEU score. More on this below.
