In September, Alphabet's DeepMind published a paper in the journal Physical Review Research detailing Fermionic Neural Network (FermiNet), a new neural network architecture that's well-suited to modeling the quantum state of large collections of electrons. The FermiNet, which DeepMind claims is one of the first demonstrations of AI for computing atomic energy, is now available in open source on GitHub -- and ostensibly remains one of the most accurate methods to date. In quantum systems, particles like electrons don't have exact locations. Their positions are instead described by a probability cloud. Representing the state of a quantum system is challenging, because probabilities have to be assigned to possible configurations of electron positions. These are encoded in the wavefunction, which assigns a positive or negative number to every configuration of electrons; the wavefunction squared gives the probability of finding the system in that configuration.

The Self-Driving car might still be having difficulties understanding the difference between humans and garbage can, but that does not take anything away from the amazing progress state-of-the-art object detection models have made in the last decade. Combine that with the image processing abilities of libraries like OpenCV, it is much easier today to build a real-time object detection system prototype in hours. In this guide, I will try to show you how to develop sub-systems that go into a simple object detection application and how to put all of that together. I know some of you might be thinking why I am using Python, isn't it too slow for a real-time application, and you are right; to some extent. The most compute-heavy operations, like predictions or image processing, are being performed by PyTorch and OpenCV both of which use c behind the scene to implement these operations, therefore it won't make much difference if we use c or python for our use case here.

Word embeddings are a type of word representation that allows words with similar meanings to have a similar representation. A word is characterized by the company it keeps -- J.R.Firth (1957) All the NLP applications we build today have a single purpose and that is to make the computers understand human language but the biggest challenge to do that makes the machines understand how we understand human language in the form of reading, writing, or speaking. To start with we first train our machine learning or deep learning algorithms to understand textual data. As machines do not understand the text we need to make the input to a machine-readable format. For example, Imagine I'm trying to describe my dog -- With all of this dog's features and precise description, anyone could draw it, even though we have never seen it.

I bet most of us have heard about "GPUs". There have been sayings that GPU is the best investment you can do for gaming. But the technology that once fancies the Gaming Industry, is now a core element of various other realms including Artificial Intelligence, Video Rendering, Healthcare. The electronic giants once used to focus solely on the gaming industry to design their GPUs, but as the corpus of AI is expanding, the demand and specialization of GPUs are increasing exponentially. The increasing attention on Deep Learning has enabled manufacturers to also focus on software rather than just hardware.

This chapter focuses on Deep Learning and techniques that can be used to keep neural networks from getting out of hand as their complexities get deeper. Traditionally Deep Learning is defined as a neural network that contains 3 or more layers. But, with this addition of layers comes additional complexity and with complexity comes more ways for a project to break. Most of this chapter deals with introducing us to the techniques that we can use to minimize these breakages when training deep models. Neural Networks are trained through backpropagation using gradient descent to adjust their weighting so that we get the intended result.

Is it possible to use large models such as GPT-3 (175B parameters) for downstream tasks with training only 37M parameters and outperform the fine-tuned model? Everyone knows there are lots of problems with the direction Deep Neural Networks models are going. It feels like they are getting larger every minute. While it is beneficial to have these pre-trained models to chose from, it is getting really hard to find enough resources to fine-tune them for any downstream task. But, What if I tell you there is no need to fine-tune the model anymore?

In the previous post, we covered RNN (Recurrent Neural Networks) and in this post we will be talking about LSTMs(Long Short Term Memory) architecture. LSTM is an extension to recurrent neural networks. They are the special kind of RNN's capable of handling Long-Term dependencies. We will discuss this later in the article. LSTMs are best known for handling sequences of data (such as speech or video).

We employ constraints to control the parameter space of deep neural networks throughout training. The use of customized, appropriately designed constraints can reduce the vanishing/exploding gradients problem, improve smoothness of classification boundaries, control weight magnitudes and stabilize deep neural networks, and thus enhance the robustness of training algorithms and the generalization capabilities of neural networks. We provide a general approach to efficiently incorporate constraints into a stochastic gradient Langevin framework, allowing enhanced exploration of the loss landscape. We also present specific examples of constrained training methods motivated by orthogonality preservation for weight matrices and explicit weight normalizations. Discretization schemes are provided both for the overdamped formulation of Langevin dynamics and the underdamped form, in which momenta further improve sampling efficiency. These optimization schemes can be used directly, without needing to adapt neural network architecture design choices or to modify the objective with regularization terms, and see performance improvements in classification tasks.

Neural shape representations have recently shown to be effective in shape analysis and reconstruction tasks. Existing neural network methods require point coordinates and corresponding normal vectors to learn the implicit level sets of the shape. Normal vectors are often not provided as raw data, therefore, approximation and reorientation are required as pre-processing stages, both of which can introduce noise. In this paper, we propose a divergence guided shape representation learning approach that does not require normal vectors as input. We show that incorporating a soft constraint on the divergence of the distance function favours smooth solutions that reliably orients gradients to match the unknown normal at each point, in some cases even better than approaches that use ground truth normal vectors directly. Additionally, we introduce a novel geometric initialization method for sinusoidal shape representation networks that further improves convergence to the desired solution. We evaluate the effectiveness of our approach on the task of surface reconstruction and show state-of-the-art performance compared to other unoriented methods and on-par performance compared to oriented methods.
