Breaking the OpenAI-Microsoft Monopoly
OpenAI has become an extremely well-known AI company after the deserved popularity of GPT-3, their celebrity AI model. GPT-3 has amazing skills, it can compose poetry, write essays, or code, but none of that could've been possible without the help of Microsoft's money and computing power. GPT-3 is arguably the most advanced language model out there (at least among those that are publicly available). As such, it'd be reasonable to make it accessible for research purposes at universities and non-profit institutes. Instead, OpenAI decided they'd limit its access to a few privileged through a private API.
Researchers Warn Of 'Dangerous' Artificial Intelligence-Generated Disinformation At Scale - Breaking Defense
A "like" icon seen through raindrops. WASHINGTON: Researchers at Georgetown University's Center for Security and Emerging Technology (CSET) are raising alarms about powerful artificial intelligence technology now more widely available that could be used to generate disinformation at a troubling scale. The warning comes after CSET researchers conducted experiments using the second and third versions of Generative Pre-trained Transformer (GPT-2 and GPT-3), a technology developed by San Francisco company OpenAI. GPT's text-generation capabilities are characterized by CSET researchers as "autocomplete on steroids." "We don't often think of autocomplete as being very capable, but with these large language models, the autocomplete is really capable, and you can tailor what you're starting with to get it to write all sorts of things," Andrew Lohn, senior research fellow at CSET, said during a recent event where researchers discussed their findings.
ECNet is an evolutionary context-integrated deep learning framework for protein engineering - Nature Communications
Machine learning has been increasingly used for protein engineering. However, because the general sequence contexts they capture are not specific to the protein being engineered, the accuracy of existing machine learning algorithms is rather limited. Here, we report ECNet (evolutionary context-integrated neural network), a deep-learning algorithm that exploits evolutionary contexts to predict functional fitness for protein engineering. This algorithm integrates local evolutionary context from homologous sequences that explicitly model residue-residue epistasis for the protein of interest with the global evolutionary context that encodes rich semantic and structural features from the enormous protein sequence universe. As such, it enables accurate mapping from sequence to function and provides generalization from low-order mutants to higher-order mutants. We show that ECNet predicts the sequence-function relationship more accurately as compared to existing machine learning algorithms by using ~50 deep mutational scanning and random mutagenesis datasets. Moreover, we used ECNet to guide the engineering of TEM-1 ฮฒ-lactamase and identified variants with improved ampicillin resistance with high success rates. Protein engineering is an active area of research in which machine learning has proven quite powerful. Here, the authors present a deep learning method that integrates both general and protein-specific sequence representations to improve the engineering of oneโs protein of interest.
Deep Learning: Recurrent Neural Networks with Python - CouponED
Deep Learning: Recurrent Neural Networks with Python Recurrent Neural Networks (RNNs), a class of neural networks, are essential in processing sequences such as sensor measurements, daily stock prices, etc. Description Recurrent Neural Networks (RNNs), a class of neural networks, are essential in processing sequences such as sensor measurements, daily stock prices, etc. In fact, most of the sequence modelling problems on images and videos are still hard to solve without Recurrent Neural Networks. Further, RNNs are also considered to be the general form of deep learning architecture. Hence, the understanding of RNNs is crucial in all the fields of Data Science. This course addresses all these concerns and empowers you to take your career to the next level with a masterful grip on the theoretical concepts and practical implementations of RNNs in Data Science.
Soon Your Google Searches Can Combine Text and Images
In May, Google executives unveiled experimental new artificial intelligence trained with text and images they said would make internet searches more intuitive. Wednesday, Google offered a glimpse into how the tech will change the way people search the web. Starting next year, the Multitask Unified Model, or MUM, will enable Google users to combine text and image searches using Lens, a smartphone app that's also incorporated into Google search and other products. So you could, for example, take a picture of a shirt with Lens, then search for "socks with this pattern." Searching "how to fix" on an image of a bike part will surface instructional videos or blog posts.
Google develops AI that can accurately predict if it will rain in the next 90 minutes
We've all been there: rushing out of the house without an umbrella only to be caught in an unexpected rain shower. But now experts at Google DeepMind have developed an artificial intelligence-based'now-casting' system which they claim is more accurate at predicting the chances of rain within the next 90 minutes than existing models. It uses high-resolution radar data from the past 20 minutes to estimate whether medium to heavy rain is likely to fall up to two hours ahead. This graphic shows how Google DeepMind's system uses high-resolution radar data from the previous 20 minutes to produce accurate predictions on rainfall to come Experts at Google DeepMind have developed an artificial intelligence-based'now-casting' system which they claim is more accurate at predicting the chances of rain within the next 90 minutes than existing models The now-casting system developed by Google's London-based tech company DeepMind relies on high-resolution radar data. The radar repeatedly fires a beam into the lower atmosphere which then tracks the amount of moisture in the air.
Recurrent Neural Network
Recurrent neural network or RNN is important and heavily used network in Natural Language Processing. RNNs is sequential network where output from previous steps feed as input to current step. RNN has concept of memory through which it able to remember the information that has been process before. Before diving into Technical stuff let's understand why do we use RNN? In our feed forward neural network two successive inputs are independent of each other means input at time t has no relation with input at time t-1 but in case we want to predict next word in sentence, it required previous information.
A deep understanding of deep learning (with Python intro)
Deep learning is increasingly dominating technology and has major implications for society. From self-driving cars to medical diagnoses, from face recognition to deep fakes, and from language translation to music generation, deep learning is spreading like wildfire throughout all areas of modern technology. But deep learning is not only about super-fancy, cutting-edge, highly sophisticated applications. Deep learning is increasingly becoming a standard tool in machine-learning, data science, and statistics. Deep learning is used by small startups for data mining and dimension reduction, by governments for detecting tax evasion, and by scientists for detecting patterns in their research data.
Capitalizing on the many artificial neural network uses
Convolutional neural networks (CNNs) are best suited for solving problems related to spatial data, such as images. Organizations use them for services such as facial recognition software, analysis of medical results (x-rays) and image classification on retail websites for targeted marketing. E-commerce sites, such as eBay, utilize CNNs to create a more efficient buying and selling platform, improving customer experience. "The use of deep learning and visual experiences has been a key focus for us," said Nitzan Mekel-Bobrov, chief AI officer at eBay. For example, eBay uses neural networks to automatically list products, such as trading cards, for sellers based on data collected from previous listings.
UC Berkeley Uses a Causal Perspective to Formalise the Desiderata for Representation Learning
Representation learning is used to summarize essential features of high-dimensional data and turn them into lower-dimensional representations with desirable properties. A popular method for this is the heuristic approach, which fits a neural network that maps from the high dimensional data to a set of labels, taking the top layer of the neural network as the representation of the inputs. However, such heuristic approaches often end up capturing spurious features that do not transfer well; or finding entangled dimensions that are uninterpretable. And while non-spuriousness or disentanglement are natural desiderata of representations, they are difficult to evaluate and optimize over algorithmically. To address this issue, a new study by UC Berkeley researchers Yixian Wang and Michael I. Jordon takes a causal perspective on representation learning, which enables the formalization of non-spuriousness, efficiency and disentanglement representation learning desiderata using causal notions.
