<h2><span style="color: #000000; font-size: 18pt;">Machine Learning Services &ndash; The Basics of Transformers&nbsp;&nbsp;</span></h2>
<p><span style="font-size: 11pt; color: #000000;">In the most basic sense, Transformers are the tools that take an input and compute it to provide an output. One primary example of technology is a translator. It takes your input in one language and then changes it per the conditions, from input to the desired output language.&nbsp; &nbsp;</span></p>
<p><span style="color: #000000;"><span style="font-size: 11pt;">So, in essence, Transformers is the process of sequential input of data, like natural language, and using the application towards tasks like translation and text summarization.&nbsp;&nbsp;</span></span></p>
<p><span style="color: #000000;"><span style="font-size: 11pt;">Some of similar or other techniques used for sequential data include&nbsp;&nbsp;</span></span></p>
<p><span style="color: #000000;"><span style="font-size: 11pt;"><strong>RNN &ndash; </strong>Recurrent Neural Networks&nbsp;&nbsp;</span></span></p>
<p><span style="color: #000000;"><span style="font-size: 11pt;"><strong>LSTM &ndash;</strong> Long Short-Term Memory&nbsp;&nbsp;</span></span></p>
<p><span style="font-size: 11pt; color: #000000;"><strong>GRU &ndash;</strong> Gated Recurrent Units&nbsp;&nbsp;</span></p>
<p><span style="color: #000000;"><span style="font-size: 14.6667px;">While all three have the same purpose, they vary significantly in their infrastructure.&nbsp;&nbsp;</span></span></p>
<p><span style="font-size: 14.6667px; color: #000000;">Now that you understand the purpose of Transformers let's go into detail about the various technologies in play.</span></p>
<p>&nbsp;</p>
<h2><span style="font-size: 18pt;">RNN&nbsp;&nbsp;</span></h2>
<p>&nbsp;</p>
<p><span style="font-size: 18pt;"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://mooglelabs165918662.files.wordpress.com/2022/08/recurrent-neural-networks-2.png" alt="Recurrent Neural Networks  " width="600" height="350" /></span></p>
<p>&nbsp;</p>
<p><span style="color: #000000;"><span style="font-size: 14.6667px;"><span style="color: #e67e23;"><a style="color: #e67e23;" title="RNNs" href="https://en.wikipedia.org/wiki/Recurrent_neural_network" target="_blank" rel="nofollow,noopener">RNNs</a> </span>are a type of neural network. The data is fed sequentially, in time series. RNN has a hidden cell state which contains sequential information encoded from previous states and passes the current hidden state as to the next time stamp. These were designed for a range of applications, including:&nbsp;</span></span></p>
<ul>
<li><span style="color: #000000;"><span style="font-size: 14.6667px;">Speech Recognition&nbsp;&nbsp;</span></span></li>
<li><span style="color: #000000;"><span style="font-size: 14.6667px;">Translation&nbsp;&nbsp;</span></span></li>
<li><span style="color: #000000;"><span style="font-size: 14.6667px;">Language Modeling&nbsp;&nbsp;</span></span></li>
<li><span style="color: #000000;"><span style="font-size: 14.6667px;">Text Summarization&nbsp;&nbsp;</span></span></li>
<li><span style="font-size: 14.6667px; color: #000000;">Image Captioning&nbsp;&nbsp;</span><span style="font-size: 14.6667px;"><br /></span></li>
</ul>
<p><span style="font-size: 14.6667px;">&nbsp;&nbsp;</span></p>
<p><strong><span style="font-size: 18pt;">LSTM&nbsp;&nbsp;</span></strong></p>
<p>&nbsp;</p>
<p><strong><span style="font-size: 18pt;"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://mooglelabs165918662.files.wordpress.com/2022/08/recurrent-neural-networks-3.png" alt="Long Short-Term Memory  " width="600" height="350" /></span></strong></p>
<p>&nbsp;</p>
<p><span style="color: #000000;"><span style="font-size: 14.6667px;"><span style="color: #e67e23;"><a style="color: #e67e23;" title="LSTM" href="https://en.wikipedia.org/wiki/Long_short-term_memory" target="_blank" rel="nofollow,noopener">LSTM</a></span> is a special kind of RNN. The technology can learn long-term dependencies and comprises three main gates:&nbsp;&nbsp;</span></span></p>
<ul>
<li><span style="color: #000000;"><span style="font-size: 14.6667px;">Forget Gate - Decides, &ldquo;How much and what information from the previous timestamp should be carried to the next timestamp?&rdquo;&nbsp;</span></span></li>
<li><span style="color: #000000;"><span style="font-size: 14.6667px;">Input Gate - Decides &ldquo;What new information can the added from the current time stamp.&rdquo;&nbsp;</span></span></li>
<li><span style="font-size: 14.6667px; color: #000000;">Output Gate - Generates the output from the current timestamp to the next timestamp.&nbsp;</span></li>
</ul>
<p><span style="font-size: 14.6667px; color: #000000;">It can do so with the help of cell state that keeps long term dependencies while still having the hidden cell state.&nbsp;</span></p>
<p><span style="font-size: 14.6667px;">&nbsp;</span></p>
<h2><span style="font-size: 18pt;">GRU&nbsp;&nbsp;</span></h2>
<p><span style="color: #000000;"><span style="font-size: 14.6667px;"><span style="color: #e67e23;"><a style="color: #e67e23;" title="GRU" href="https://en.wikipedia.org/wiki/Gated_recurrent_unit" target="_blank" rel="nofollow,noopener">GRU</a></span> is essentially an advancement in standard RNN. They are more recent than LSTM and, while being similar, do have added advantages from this technology. It has no separate cell state, but it does have a hidden state.&nbsp; &nbsp;</span></span></p>
<ul>
<li><span style="color: #000000;"><span style="font-size: 14.6667px;">Reset Gate&nbsp;</span><span style="font-size: 14.6667px;"><br /></span></span></li>
<li><span style="font-size: 14.6667px; color: #000000;">Update Gate&nbsp;&nbsp;</span></li>
</ul>
<p><span style="color: #000000;"><span style="font-size: 14.6667px;">It is faster to train the GRU system than RNN and LSTM.&nbsp;</span></span></p>
<p><span style="font-size: 14.6667px; color: #000000;">The purpose of Gates is to work as the threshold to help the network determine when to use the normal stacked layers versus the identity connection.&nbsp;</span></p>
<h2>&nbsp;</h2>
<h2><span style="font-size: 18pt;">Understanding The Encoder-Decoder Architecture&nbsp;</span></h2>
<p><span style="font-size: 11pt; color: #000000;">The transformers use encoder-decoder architecture. The encoder's role is to extract features from the input sentence, and the decoder is responsible for using the features to create an output sentence.&nbsp;</span></p>
<p><span style="font-size: 11pt; color: #000000;">There are several encoder blocks in a transformer, known as encoder stack, and the input goes through the multiple encoder blocks. Then, the last encoder block becomes the input feature of the decoder stack given the special token or End of Sentence (EOS).&nbsp;</span></p>
<p><span style="font-size: 11pt; color: #000000;">The decoder also has several blocks known as decoder stack.&nbsp;</span></p>
<p><span style="font-size: 11pt; color: #000000;">The decoder aims to understand the input and use it to draw up a conclusion.&nbsp;&nbsp;</span></p>
<p>&nbsp;</p>
<p><span style="font-size: 11pt; color: #000000;"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://mooglelabs165918662.files.wordpress.com/2022/08/recurrent-neural-networks-4.png" alt="Understanding The Encoder-Decoder Architecture " width="600" height="350" /></span></p>
<p>&nbsp;</p>
<h2><span style="font-size: 18pt;">Attention&nbsp;</span></h2>
<p><span style="color: #000000;"><span style="font-size: 14.6667px;"><span style="color: #e67e23;"><a style="color: #e67e23;" title="Attention" href="https://en.wikipedia.org/wiki/Attention_(machine_learning)" target="_blank" rel="nofollow,noopener">Attention</a></span> is the part of neural networks that mimic cognitive attention in humans. It helps determine the tokens or parts of the input that need more weightage and those that need less weightage.&nbsp;</span></span></p>
<p><span style="color: #000000;"><span style="font-size: 14.6667px;">Attention was good in keeping long-term sequences. For the previous systems, it was not possible to have inferred information.&nbsp;&nbsp;</span></span></p>
<p><span style="color: #000000;"><span style="font-size: 14.6667px;">In neural networks, attention helps mimic cognitive attention. This results in the enhancement of some parts of the input while diminishing other parts. The technique helps ensure that the network focuses on small yet essential elements of the data.&nbsp;</span></span></p>
<ul>
<li><span style="color: #000000;"><span style="font-size: 14.6667px;">Scaled Dot-Product Attention&nbsp;&nbsp;</span></span></li>
<li><span style="font-size: 14.6667px; color: #000000;">Multi-Head Attention&nbsp;&nbsp;</span></li>
</ul>
<p><span style="color: #000000;"><span style="font-size: 14.6667px;">Attention came well before. The Transformer model in ML was generated through attention technology.&nbsp;</span></span></p>
<p><span style="font-size: 14.6667px; color: #000000;">Math is the language of computers. Hence, it is only natural that both the systems use mathematical formulas.&nbsp;</span></p>
<h2>&nbsp;</h2>
<h2><span style="font-size: 18pt;">Machine Learning - How Attention Works?&nbsp;</span></h2>
<p><span style="color: #000000;"><span style="font-size: 14.6667px;">In the learning phase, attention works differently. You give the model sentences with a special token at the end and start with the next sentence. Attention bits are generated as per the information and the formula in play. Attention bits assign weight to every piece of information, per the learning model. The context vector is multiplied with weights, and then the output is generated through it.&nbsp;&nbsp;</span></span></p>
<p>&nbsp;</p>
<p><span style="font-size: 14.6667px; color: #000000;">In this process, we get hidden states, use the already learned weights, normalize the weights, and multiply both to get the context vector that is used to get the outputs.&nbsp;</span></p>
<p>&nbsp;</p>
<p><span style="font-size: 14.6667px; color: #000000;"><img style="display: block; margin-left: auto; margin-right: auto;" src="https://mooglelabs165918662.files.wordpress.com/2022/08/how-attention-works-2.png" alt="Machine Learning - How Attention Works? " width="600" height="700" /></span></p>
<p>&nbsp;</p>
<p><span style="font-size: 14.6667px; color: #000000;">Currently, one of the best examples of Transformers in use is Bert. It is a transformer model by Google. Bert stands for Bidirectional Encoder Representations from Transformers and is being trained for various purposes. Bert is an encoder-only stack. It is called bidirectional because the information is given two ways.&nbsp;&nbsp;</span></p>
<p><span style="font-size: 14.6667px;">&nbsp;</span></p>

<p>&nbsp;</p>
<p><span style="font-size: 11pt; color: #000000;">Currently, one of the best examples of Transformers in use is Bert. It is a transformer model by Google. <span style="color: #e67e23;"><a style="color: #e67e23;" title="Bert" href="https://en.wikipedia.org/wiki/BERT_(language_model)" target="_blank" rel="nofollow,noopener">Bert</a></span> stands for Bidirectional Encoder Representations from Transformers and is being trained for various purposes. Bert is an encoder-only stack. It is called bidirectional because the information is given two ways.&nbsp;&nbsp;</span></p>
<p><span style="font-size: 11pt; color: #000000;">It comes in a range of variations to tackle different problems, namely, RoBERTa, ALBERT, ELECTRA, XLNet, DistilBERT, SPANBERT, and BERTSUM.&nbsp;</span></p>
<p><span style="font-size: 11pt; color: #000000;">Here are the Bert Data Sets&nbsp;&nbsp;</span></p>
<p><span style="font-size: 11pt; color: #000000;"><strong>MNLI:</strong> Multi-lingual Natural Language Interface&nbsp;&nbsp;</span></p>
<p><span style="font-size: 11pt; color: #000000;"><strong>QQP: </strong>Question-Question Pair&nbsp;&nbsp;</span></p>
<p><span style="font-size: 11pt; color: #000000;"><strong>SQuAD:</strong> Stanford Question Answering Dataset&nbsp;&nbsp;</span></p>
<p>&nbsp;</p>
<p><span style="color: #000000; font-size: 11pt;">At MoogleLabs, a machine learning consulting company, they are working on a question generation task where the text is in the Hungarian language. For this purpose, we are using the SQuAd model, which has been working well.&nbsp;&nbsp;</span></p>
<p><span style="color: #000000; font-size: 11pt;">In essence, you can take the appropriate transformer model and change the last few layers to get the appropriate results.&nbsp;</span></p>
<p><span style="color: #000000; font-size: 11pt;">Transfer learning, which relies on information gained from solving one problem to resolve a different yet related problem helps increase its application.&nbsp;</span></p>
<p><span style="color: #000000; font-size: 11pt;">Moreover, during the transfer learning, new IoT can be developed to better meet the needs of the new problem.&nbsp;</span></p>
<p>&nbsp;</p>

<p>&nbsp;</p>
<h3>Text Summarization&nbsp;&nbsp;</h3>
<p><span style="font-size: 11pt; color: #000000;">Text summarization refers to shortening the text without compromising the semantic structure of the body of information. It can occur through an extractive or abstractive approach.&nbsp;&nbsp;</span></p>
<p>&nbsp;</p>
<h3>Text Classification&nbsp;&nbsp;</h3>
<p><span style="font-size: 11pt; color: #000000;">Text classification service is available to categorize text in already organized groups. It essentially helps tag the content based on its category.&nbsp;&nbsp;</span></p>
<p>&nbsp;</p>
<h3>Name Entity Recognition (NER)&nbsp;&nbsp;</h3>
<p><span style="font-size: 11pt; color: #000000;">The purpose of named entity recognition (NER) is information extraction that aims to seek and categorize particular entities in one or several bodies of text.&nbsp; &nbsp;</span></p>
<p>&nbsp;</p>
<h3>Speech Recognition&nbsp;&nbsp;</h3>
<p><span style="font-size: 11pt; color: #000000;">When humans offer speech input for typing or searching, natural language processing uses this technology to turn the input into a relevant context for the computer to understand and then provide appropriate action. It can include both recognition and translation of the speech input.&nbsp;&nbsp;</span></p>
<p>&nbsp;</p>
<h3>Language Modelling&nbsp;&nbsp;</h3>
<p><span style="font-size: 11pt; color: #000000;">Language modeling analyzes the data to provide a basis for their word predictions. The tool is mainly used to generate text as output.&nbsp;</span></p>
<p>&nbsp;</p>
<h3>Image Captioning&nbsp;&nbsp;</h3>
<p><span style="color: #000000; font-size: 11pt;">Transformers also have provisions to create image captioning. It consists of getting information in the visual format and decoding it to make a descriptive caption for the image.&nbsp;</span></p>
<p>&nbsp;</p>
<h3>Text-to-Image Generation&nbsp;&nbsp;</h3>
<p><span style="color: #000000; font-size: 11pt;">Text-to-image generation includes providing cues to the software and letting it create an image per the text available. Here, the machine needs to comprehend the text to create the image.&nbsp;&nbsp;</span></p>
<p>&nbsp;</p>
<h3>Video Generation&nbsp;&nbsp;</h3>
<p><span style="font-size: 11pt; color: #000000;">Video generation through transformers includes mapping a sequence of random vectors to a sequence of video frames. Here, the motion is not affected by the text.&nbsp;&nbsp;</span></p>
<p>&nbsp;</p>
<h3>Article Generation&nbsp;&nbsp;</h3>
<p><span style="font-size: 11pt; color: #000000;">Article generation includes providing the system keywords and letting it create content based on the input. It reduces content-generation time significantly.&nbsp;&nbsp;</span></p>
<p>&nbsp;</p>
