In the present research, we delve into the intricate realm of electroencephalogram (EEG) data analysis, focusing on sequence-to-sequence prediction of data across 32 EEG channels. The study harmoniously fuses the principles of applied chaos theory and dynamical systems theory to engender a novel feature set, enriching the representational capacity of our deep learning model. The endeavour's cornerstone is a transformer-based sequence-to-sequence architecture, calibrated meticulously to capture the non-linear and high-dimensional temporal dependencies inherent in EEG sequences. Through judicious architecture design, parameter initialisation strategies, and optimisation techniques, we have navigated the intricate balance between computational expediency and predictive performance. Our model stands as a vanguard in EEG data sequence prediction, demonstrating remarkable generalisability and robustness. The findings not only extend our understanding of EEG data dynamics but also unveil a potent analytical framework that can be adapted to diverse temporal sequence prediction tasks in neuroscience and beyond.

In this paper, we introduce MCTensor, a library based on PyTorch for providing general-purpose and high-precision arithmetic for DL training. MCTensor is used in the same way as PyTorch Tensor: we implement multiple basic, matrix-level computation operators and NN modules for MCTensor with identical PyTorch interface. Our algorithms achieve high precision computation and also benefits from heavily-optimized PyTorch floating-point arithmetic. We evaluate MCTensor arithmetic against PyTorch native arithmetic for a series of tasks, where models using MCTensor in float16 would match or outperform the PyTorch model with float32 or float64 precision.

This blog is part of the Torch Thursdays series. The plan is to share some tidbits on PyTorch usage through this. Today's blog particularly is to share some quick notes based on PyTorch's video tutorial on tensors. This blog assumes familiarity with PyTorch framework and numpy. PyTorch provides torch.Tensor to represent a multi-dimensional array containing elements of a single data type.

Recently, Microsoft and PyTorch announced a "PyTorch Fundamentals" tutorial, which you can find on Microsoft's site and on PyTorch's site. The code in this post is based on the code appearing in that tutorial, and forms the foundation for a series of other posts, where I'll explore other machine learning frameworks and show integration with Azure ML. In this post, I'll explain how you can create a basic neural network in PyTorch, using the Fashion MNIST dataset as a data source. The neural network we'll build takes as input images of clothing, and classifies them according to their contents, such as "Shirt," "Coat," or "Dress." I'll assume that you have a basic conceptual understanding of neural networks, and that you're comfortable with Python, but I assume no knowledge of PyTorch. Let's start by getting familiar with the data we'll be using, the Fashion MNIST dataset. This dataset contains 70,000 grayscale images of articles of clothing -- 60,000 meant to be used for training and 10,000 meant for testing.

Before even calculating the predictions we have to ensure that the data is structured in the same way for the program to process all the different images. Let's make sure that we have two different tensors, each for all of the'nines' and'twos' in the dataset. Before progressing further, we have to discuss what exactly is a tensor. I first heard of the word tensor in the name TensorFlow, which is a (completely!) A PyTorch Tensor in this case is a multidimensional table of data, with all data items of the same type.

With the rise in technological advancements in the field of artificial neural networks, there have been several libraries that are used to solve and compute modern deep learning tasks. In my previous articles, I have covered some other deep learning frameworks, such as TensorFlow and Keras, in detail. It is recommended that the viewers who are new to this topic to out the following link for TensorFlow and this particular link for Keras. In this article, we will cover another spectacular deep learning framework in PyTorch, which is also widely used for performing a variety of complex tasks. PyTorch, since its release in September 2016, has always offered stiff competition to TensorFlow due to its Pythonic style of coding archetypes and comparatively more simple coding methodologies in some cases. The table of contents for the concepts we will discuss in this article is provided on the right. For starters, we will get accustomed to PyTorch with a basic introduction.

As we know, PyTorch is a popular, open source ML framework and an optimized tensor library developed by researchers at Facebook AI, used widely in deep learning and AI Research. The torch package contains data structures for multi-dimensional tensors (N-dimensional arrays) and mathematical operations over these are defined. In this blog post, we seek to cover some of the useful functions that the torch package provides for tensor manipulation, by looking at working examples for each and an example when the function doesn't work as expected. This function concatenates the given sequence of tensors along the given dimension. All tensors must either have the same shape (except in the concatenating dimension) or be empty.

Making code run fast on GPUs requires a very different approach to making code run fast on CPUs because the hardware architecture is fundamentally different. If you come from a background of efficient coding on CPU then you'll have to adjust some assumptions about what patterns are best. Machine learning engineers of all kinds should care about squeezing performance from their models and hardware -- not just for production purposes, but also for research and training. In research as in development, a fast iteration loop leads to faster improvement. This article is a practical deep dive into making a specific deep learning model (Nvidia's SSD300) run fast on a powerful GPU server, but the general principles apply to all GPU programming.

PyTorch is an open source Machine Learning library based on the Torch library, used for applications such as computer vision and natural language processing. PyTorch is an open source Machine Learning library based on the Torch library, used for applications such as computer vision and natural language processing. This tutorial introduces the fundamental concepts of PyTorch through self-contained examples. We will use a fully-connected ReLU network as our running example. The network will have a single hidden layer, and will be trained with gradient descent to fit random data by minimizing the Euclidean distance between the network output and the true output.

Recent advances in training deep neural networks have led to a whole bunch of impressive machine learning models which are able to tackle a very diverse range of tasks. When you are developing such a model, one of the notable downsides is that it is considered a "black-box" approach in the sense that your model learns from data you feed it, but you don't really know what is going on inside the model. To make it clearer: you don't really know what your model actually learned and if you have a flaw in your training / data approach it might work well according to your metrics while having learnt the wrong thing. As a self-respecting developer you want to do better than that, so today I will show you a method you can use to get some better introspection into your model by using visualization techniques. So what is a visualization techniqe when we talk about deep neural networks?
