An artificial intelligence (AI) technology made by a firm co-founded by billionaire Elon Musk has won praise for its ability to generate coherent stories, novels and even computer code but it remains blind to racism or sexism. GPT-3, as Californian company OpenAI's latest AI language model is known, is capable of completing a dialogue between two people, continuing a series of questions and answers or finishing a Shakespeare-style poem. Start a sentence or text and it completes it for you, basing its response on the gigantic amount of information it has been fed. This could come in useful for customer service, lawyers needing to sum up a legal precedent or for authors in need of inspiration. While the technology is not new and has not yet learnt to reason like a human mind, OpenAI's latest offering has won praise for the way its text resembles human writing.

Such functions can be regarded as vector functions. Linear vector functions, also known as linear operators, are of great importance in linear algebra and it's applications. We can write down the general representation of a linear form L(x) defined on an n-dimensional space K_n. Let e1, e2, …, en be and arbitrary basis of the space know, and denote the quantity L(e_k) by l_k (k 1,2,…,n). A morphism A A(x) of a linear space X is another linear space Y over the same filed k.

MR imaging is a powerful and diverse imaging technique employed to investigate and diagnose a range of diseases in different body areas. MRI scans are acquired by employing specific parameters in a "sequence" to encode in data in arbitrary space known as "k-space". Image is reconstructed by applying mathematical transforms (mainly Fourier) to the k-space data. To obtain images of particular contrast (T1w, T2w, T2* etc) optimal sequence settings must be employed. Briefly, image contrast arise from magnetic property of the hydrogen atoms, that can varied setting such as echo time and Tr in sequence setting.

Training the popular GPT-3 from scratch can cost millions of dollars. But, what if an individual researcher wants to experiment on such a large scale? It is almost impossible to generate funds for toying with networks. To address this large gap between innovation and computation in ML, a team of researchers from Russia have introduced Learning@home -- a neural network training paradigm that handles large amounts of poorly connected participants. "Hypothetically, a researcher could crowdsource the training of large neural networks with thousands of regular PCs provided by volunteers. The raw computing power of a hundred thousand $2500 desktops dwarfs that of a $250M server pod," wrote the researchers.

What do NeuraLink and OpenAI have in common? They are both on a quest to synthesize intelligence using a wet lab vs. dry lab approach. Neuralink [wet lab] is trying to interact with the brain and learn straight from the source through implantable brain-machine interfaces. OpenAI [dry lab] is looking to emulate brain functions in the real world. The OpenAI researchers want to democratize access to safe artificial intelligence.

It's an essential prerequisite for deciding how we want critical decisions about our health and well-being to be made -- possibly for a very long time to come. To understand why the "how" behind AI functionality is so important, we first have to appreciate the fact that there have historically been two very different approaches to AI. The first is symbolism, which deals with semantics and symbols. Many early AI advances utilized a symbolistic approach to AI programming, striving to create smart systems by modeling relationships and using symbols and programs to convey meaning. But it soon became clear that one weakness to these semantic networks and this "top-down" approach was that true learning was relatively limited.

Cross-network recommender systems use auxiliary information from multiple source networks to create holistic user profiles and improve recommendations in a target network. However, we find two major limitations in existing cross-network solutions that reduce overall recommender performance. Existing models (1) fail to capture complex non-linear relationships in user interactions, and (2) are designed for offline settings hence, not updated online with incoming interactions to capture the dynamics in the recommender environment. We propose a novel multi-layered Long Short-Term Memory (LSTM) network based online solution to mitigate these issues. The proposed model contains three main extensions to the standard LSTM: First, an attention gated mechanism to capture long-term user preference changes. Second, a higher order interaction layer to alleviate data sparsity. Third, time aware LSTM cell gates to capture irregular time intervals between user interactions. We illustrate our solution using auxiliary information from Twitter and Google Plus to improve recommendations on YouTube. Extensive experiments show that the proposed model consistently outperforms state-of-the-art in terms of accuracy, diversity and novelty.

RNAs play crucial and versatile roles in biological processes. Computational prediction approaches can help to understand RNA structures and their stabilizing factors, thus providing information on their functions, and facilitating the design of new RNAs. Machine learning (ML) techniques have made tremendous progress in many fields in the past few years. Although their usage in protein-related fields has a long history, the use of ML methods in predicting RNA tertiary structures is new and rare. Here, we review the recent advances of using ML methods on RNA structure predictions and discuss the advantages and limitation, the difficulties and potentials of these approaches when applied in the field. Introduction RNAs are macromolecules of crucial and versatile biological functions. To fully understand their functions, knowledge of the three-dimensional (3D) structures is essential. Since experimental approaches to determinate RNA 3D structures are difficult and expensive, many computational approaches have been developed to this purpose. To date, although template-based and homology-modeling methods could achieve high accuracies, de novo predictions still depends on the size and complexity of the RNA, and further improvement in predicting non-canonical interactions are required, according to the recent RNA-Puzzles round III. For a comprehensive study of the recent work, we refer readers to the relevant literature.
