Temporal Fusion Transformers, as described in the Temporal Fusion Transformers for Interpretable Multi-horizon Time Series Forecasting article by Lim et al. [1], use a complex mix of inputs to provide multi-horizon forecasting for timeseries data. The first step in understanding these models is to understand the data inputs fed into the model and the predicted outputs …

In our latest release, version 1.12.0.60, we now support ChatGPT type architectures with Encoder/Decoder Transformer Models based on the open-source transformer-translator-pytorch GitHub project by Song [1]. ChatGPT uses encoder/decoder transformer models to learn the context of the input query, the context of the likely responses and a mapping between the two via attention layers. The …
With GPT and ChatGPT, transformer models have been proven to be very powerful AI models. However, how do they work on the inside? With this post, we use the SignalPop AI Designer to visually walk through the forward pass of a transformer model used for language translation. Before showing a visual walk-through we wanted to …

While completing the MyCaffe implementation of the transformer encoder/decoder model for language translation, we ran into a very difficult bug to fix – in fact it was the kind of bug feared most when developing a model for with this bug everything appeared to work as expected when training. Yet, the model would train up …
When training any deep learning AI model, knowing your data is critical. This is especially important when training a transformer-based encoder/decoder model for data ordering is important. In this post, we analyze the Python open-source language translation encoder/decoder transformer model by Jaewoo (Kyle) Song [1] which is based on the ‘Attention Is All You Need‘ …

GPT is a great transformer model used to solve many natural language problems, however GPT only implements the encoder side of a full encoder/decoder transformer model as described by Vaswani et al. [1]. Only a few changes are needed to implement a full encoder/decoder transformer model as shown below (GPT portion inspired by the minGPT …

In our latest release, version 1.11.8.27, we now support GPT and Transformer Models based on the open source minGPT GitHub project by Karpathy [1]. GPT uses transformer models to learn the context of the input data via attention layers. Stacking up a set of transformer blocks tends to learn context at several different levels from …

In our latest release, version 1.11.7.7, we showcase several new loss samples that demonstrate binary classification, multi-class classification, multi-label classification and regression with the new MSE and MAE layers – all using the latest NVIDIA CUDA 11.7.1 / cuDNN 8.4.1 release. Binary Classification The binary classification sample solves a simple 2-class classification problem, where the …
The SignalPop Trading Studio is Windows Store App that provides short-term option traders with real-time analytics geared to help the trader better understand what the market is doing during each intra-day trading session. Part of the analytics provided by the SignalPop Trading Studio include real-time, AI driven price directional predictions which when taken together give …

minGPT, created by Andrej Karpathy, is a simplified implementation of the original OpenAI GPT-2 open-source project. GPT has proven very useful in solving many Natural Language Processing problems (NLP) and as shown by Karpathy and others, also used to solve tasks outside of the NLP domain such as generative image processing and classification. One of …
