In order to celebrate the 100,000 stars of transformers, we have decided to put the spotlight on thecommunity, and we have created the awesome-transformers page which lists 100incredible projects built in the vicinity of transformers.
An electrical transformer is a device that converts electricity from one potential to another by changing voltage levels. Transformers improve the safety and efficiency of power systems by raising or lowering voltage levels as needed. In the commercial and industrial environments, they are used in the distribution and regulation of power across long distances. Transformer failures lead to power outages and, depending on what is consuming the power, determines how widespread and how critical the outage will be. Can transformers be monitored to identify faults before an actual failure occurs? The answer is YES!
Condition based maintenance is key to avoiding a transformer failure and unplanned power interruption. A preventive maintenance schedule on transformers also facilitates replacement and budget planning for the company. Technologies exist today that allow the maintenance team to detect early warning signs of failure. These technologies include:
EMSDs make routine inspections of transformers easier and safer to perform. A condition based maintenance strategy collects and trends inspection data over time allowing the maintenance team to assess and monitor the health of transformers. Fixing a problem before acute failure occurs saves a company time, money and more importantly, eliminates power outages to the end user customer.

We develop and evaluate two deep learning architectures, an image-based (MACSSwin-T) and a video-based (vidMACSSwin-T) for performing aneurysm detection and classification, based on the lightweight version of the shifted-windows Transformer model (Swin-T) [11]. Attention-based learning architectures have been previously adapted for surgical video analysis and applied in tasks such as depth estimation [12], phase recognition [13] and instruction generation [14].
We formulate our problem as a frame classification task and adapt the tiny version of the Transformer model using shifted-windows (Swin-T) [11] to tackle it. The proposed architecture is illustrated in Fig. 3. The MACSSwin-T model extracts features at 4 stages, where each stage consists of multiple consecutive Swin Transformer blocks. Each block is composed by a shifted-window multi-head self-attention (MSA) layer and a 2-layer MLP with GELU activation functions in between. Global average pooling is applied to the feature maps, resulting in a 768-dimensional feature vector, processed by a single-layer perceptron with softmax activation to predict the final class (aneurysm presence/absence).
In the SWIN transformer, the local self-attention is applied in non-overlapping windows. The window-to-window communication in the next layer produces a hierarchical representation by progressively merging the windows themselves5.
Let's make it clear, the return of plastic windows (or even just open windows) won't stop theft. It'll just make our life easier by not unknowingly buying an incomplete or swapped figure. If you read the conversation, that's usually the real motivator for people's objections to the lack of a window.
Is this a joke? The main problem with plastic free packaging wasn't that people were stealing transformers due to open-window packaging, but that people were swapping figures from closed-box packaging and returning a different figure (or a box of rocks or something) to a store with it being hard to tell if you were going to get what you actually were purchasing. I don't think stealing from the open window packaging has really been an issue and anecdotally I have seen more people stealing smaller figures (Marvel Legends, Black Series, etc) from closed box packaging due to how weak they now are than Transformers with open window packaging.
Deep-learning models have enabled performance leaps in analysis of high-dimensional functional MRI (fMRI) data. Yet, many previous methods are suboptimally sensitive for contextual representations across diverse time scales. Here, we present BolT, a blood-oxygen-level-dependent transformer model, for analyzing multi-variate fMRI time series. BolT leverages a cascade of transformer encoders equipped with a novel fused window attention mechanism. Encoding is performed on temporally-overlapped windows within the time series to capture local representations. To integrate information temporally, cross-window attention is computed between base tokens in each window and fringe tokens from neighboring windows. To gradually transition from local to global representations, the extent of window overlap and thereby number of fringe tokens are progressively increased across the cascade. Finally, a novel cross-window regularization is employed to align high-level classification features across the time series. Comprehensive experiments on large-scale public datasets demonstrate the superior performance of BolT against state-of-the-art methods. Furthermore, explanatory analyses to identify landmark time points and regions that contribute most significantly to model decisions corroborate prominent neuroscientific findings in the literature.
While there is currently no standard method of circumventing this issue, a plausible strategy is to use the sliding window approach. Here, any sequence exceeding the max_seq_length will be split into several windows (sub-sequences), each of length max_seq_length.
The windows will typically overlap each other to a certain degree to minimize any information loss that may be caused by hard cutoffs. The amount of overlap between the windows is determined by the stride. The stride is the distance (in terms of number of tokens) that the window will be, well, slid to obtain the next sub-sequence.
That enables these models to ride a virtuous cycle in transformer AI. Created with large datasets, transformers make accurate predictions that drive their wider use, generating more data that can be used to create even better models.
Before transformers arrived, users had to train neural networks with large, labeled datasets that were costly and time-consuming to produce. By finding patterns between elements mathematically, transformers eliminate that need, making available the trillions of images and petabytes of text data on the web and in corporate databases.
NVIDIA and Microsoft hit a high watermark in November, announcing the Megatron-Turing Natural Language Generation model (MT-NLG) with 530 billion parameters. It debuted along with a new framework, NVIDIA NeMo Megatron, that aims to let any business create its own billion- or trillion-parameter transformers to power custom chatbots, personal assistants and other AI applications that understand language.

Once the models are downloaded, one option to configure them is to create a YAML configuration file.Note that the configuration needs to contain both a spaCy pipeline name and a transformers model name.In addition, different configurations for parsing the results of the transformers model can be added.
In addition to the approach described in this document, one can decide to integrate a transformers model as a recognizer.We allow these two options, as a user might want to have multiple NER models running in parallel. In this case, one can create multiple EntityRecognizer instances, each serving a different model, instead of one model used in an NlpEngine. See this sample for more info on integrating a transformers model as a Presidio recognizer and not as a Presidio NLPEngine.
