II. Planetary Prodigy: A Global Sapiensphere Learns by Her/His Self

1. Earthificial Intelligence: Deep Neural Network Learning

Silver, David, et al. Mastering the Game of Go without Human Knowledge. Nature. 550/354, 2017. An 18 member team (all male) from the Google’s DeepMind London artificial intelligence group including founder Demis Hassabis and AlphaGo European winner Fan Hui enhance the capabilities of their neural network learning programs. With regard to the second quote for the gist of the paper, these algorithmic, reinforcement methods appear as a microcosm of an ascendant, self-reinforcing evolutionary education as it may at last reach a consummate worldwise sapience. While we are wary of game metaphors, a vital truth could be gleaned. What am I trying to say – to wit that a universe to human quickening procreation seems like a game that plays itself. In regard, it may be the case that only one sentient ovoplanet is needed to achieve its self-observation, and realization, so as in this venue, “to log on to itself.” While life’s course is a long slog of stochastic chance, rife with injustice and tragedy, it is a game that yet can be won. As Great Earth, Natural Algorithms, Cosmo Opus and elsewhere try to evoke, our Geonate moment may give us an opportunity to be the fittest people and planet by virtue of a Cosmonate act of self-selection and continuance.

A long-standing goal of artificial intelligence is an algorithm that learns, tabula rasa, superhuman proficiency in challenging domains. Recently, AlphaGo became the first program to defeat a world champion in the game of Go. The tree search in AlphaGo evaluated positions and selected moves using deep neural networks. These neural networks were trained by supervised learning from human expert moves, and by reinforcement learning from self-play. Here we introduce an algorithm based solely on reinforcement learning, without human data, guidance or domain knowledge beyond game rules. AlphaGo becomes its own teacher: a neural network is trained to predict AlphaGo’s own move selections and also the winner of AlphaGo’s games. This neural network improves the strength of the tree search, resulting in higher quality move selection and stronger self-play in the next iteration. Starting tabula rasa, our new program AlphaGo Zero achieved superhuman performance, winning 100–0 against the previously published, champion-defeating AlphaGo. (Abstract)

Conclusion Humankind has accumulated Go knowledge from millions of games played over thousands of years, collectively distilled into patterns, proverbs and books. In the space of a few days, starting tabula rasa, AlphaGo Zero was able to rediscover much of this Go knowledge, as well as novel strategies that provide new insights into the oldest of games. (358)

Soltoggio, Andrea, et al. Born to Learn: the Inspiration, Progress, and Future of Evolved Plastic Artificial Neural Networks. Neural Networks. 108/48, 2018. Loughborough University, University of Central Florida and University of Copenhagen computer scientists draw upon the evolutionary and biological origins of this ubiquitous multicomplex learning system to achieve further understandings and usages. Their theme is that life’s temporal development seems to be a learning, neuromodulation, plasticity, and discovery progression. The approach is seen as akin to the Evolutionary Neurodynamics school of Richard Watson, et al, see section V.C. See also herein Evolution in Groups: A Deeper Look at Synaptic Cluster Driven Evolution of Deep Neural Networks (M. Shafiee) and other similar entries.

Biological neural networks are systems of extraordinary computational capabilities shaped by evolution, development, and lifetime learning. Inspired by such intricate natural phenomena, Evolved Plastic Artificial Neural Networks (EPANNs) use simulated evolution in-silico to breed plastic neural networks, artificial systems composed of sensors, outputs, and plastic components that change in response to sensory-output experiences in an environment. These systems may reveal key algorithmic ingredients of adaptation, autonomously discover novel adaptive algorithms, and lead to hypotheses on the emergence of biological adaptation. In particular, the limitations of hand-designed structures and algorithms currently used in most deep neural networks could be overcome by more flexible and innovative solutions. This paper brings together a variety of inspiring ideas that define the field of EPANNs. (Abstract)

Over the course of millions of years, evolution has led to the emergence of innumerable biological systems, and intelligence itself, crowned by the discovery of the human brain. Evolution, development, and learning are the fundamental processes that underpin biological intelligence. Thus, it is no surprise that scientists have modeled artificial systems to reproduce such phenomena. However, our current knowledge of evolution, biology, and neuroscience remains insufficient to provide clear guidance on the essential mechanisms that are key to the emergence of such complex systems.

This paper frames the field that attempts to evolve plastic artificial neural networks, and introduces the acronym EPANN. EPANNs are evolved because parts of their design are determined by an evolutionary algorithm; they are plastic because they undergo various time-scale changes, beyond neural activity, while experiencing sensory-motor information streams during a lifetime simulation. The final capabilities of such networks are a result of genetic instructions, determined by evolution, that enable learning once the network is placed in an environment. Static ANNs with evolved connection weights are not considered EPANN. (1) Whilst the range of inspiring ideas is large and heterogeneous, the analysis in this review proposes that EPANNs build upon five main concepts: evolutionary processes, inspiration from biological neural networks, abstractions in brain simulations, artificial plastic neural networks, and intelligence-testing environments.

Much of recent machine learning has focused on deep learning, in which neural network weights are trained through variants of stochastic gradient descent. An alternative approach comes from the field of neuroevolution, which harnesses evolutionary algorithms to optimize neural networks, inspired by the fact that natural brains themselves are the products of an evolutionary process. Neuroevolution enables important capabilities that are typically unavailable to gradient-based approaches, including learning neural network building blocks, hyperparameters, architectures and algorithms for learning itself. Neuroevolution differs deep reinforcement learning via a population of solutions during search, enabling exploration and parallelization. This Review looks at several key aspects of modern neuroevolution, including large-scale computing, the benefits of novelty and diversity, the power of indirect encoding, and the field’s contributions to meta-learning and architecture search.

Vaidya, Satyarth, et al. Brief Review of Computational Intelligence Algorithms. arXiv:1901.00983. Birla Institute of Technology and Science, Pilani Campus, Dubai computer scientists survey a wide array of brain-based and indigenous algorithmic methods, along with showing how they are finding service in far afield domains from geology to cerebral phenomena.

Computational Intelligence algorithms have been found to deliver near optimal solutions. In this paper we propose a new hierarchy which classifies algorithms based on their sources of inspiration. The algorithms have two broad domains namely modeling of human mind and nature inspired intelligence. Algorithms of Modeling of human mind take their motivation from the manner in which humans perceive and deal with information. Similarly algorithms of nature inspired intelligence are based on ordinary phenomenon occurring in nature. The latter has further been broken into swarm intelligence, geosciences and artificial immune system. (Abstract)

Deep learning methods employ multiple processing layers to learn hierarchical representations of data, and have produced state-of-the-art results in many domains. Recently, a variety of model designs and methods have blossomed in the context of natural language processing (NLP). In this paper, we review significant deep learning related models and methods that have been employed for numerous NLP tasks and provide a walk-through of their evolution. We also summarize, compare and contrast the various models and put forward a detailed understanding of the past, present and future of deep learning in NLP. (Abstract)

Yue, Tianwei and Haohan Wang. Deep Learning for Genomics: A Concise Overview. arXiv:1802.00810. Xi’an Jiaotong University and Carnegie Mellon University scientists post an invited chapter for the 2018 Springer edition Handbook of Deep Learning Applications. We record as an example of how so many natural and social realms are now being treated by way of an organic neural network-like cognitive process.

Advancements in genomic research such as high-throughput sequencing techniques have driven modern genomic studies into "big data" disciplines. This data explosion is constantly challenging conventional methods used in genomics. In parallel with the urgent demand for robust algorithms, deep learning has succeeded in a variety of fields such as vision, speech, and text processing. Yet genomics entails unique challenges since we are expecting from deep learning a superhuman intelligence that explores beyond our knowledge to interpret the genome. In this paper, we briefly discuss the strengths of different models from a genomic perspective so as to fit each particular task with a proper deep architecture. (Abstract excerpts)

Zhu, Jun, et al. Big Learning with Bayesian Methods. National Science Review. Online May, 2017. In this Oxford Academic journal of technical advances from China, as their AI programs intensify State Key Lab for Intelligent Technology and Systems, Tsinghua University, computer scientists consider this iterative method of winnowing uncertainties and probabilities, often with massive data input, so as to reach sufficiently credible answers unto knowledge.

The explosive growth in data volume and the availability of cheap computing resources have sparked increasing interest in Big learning, an emerging subfield that studies scalable machine learning algorithms, systems and applications with Big Data. Bayesian methods represent one important class of statistical methods for machine learning, with substantial recent developments on adaptive, flexible and scalable Bayesian learning. This article provides a survey of the recent advances in Big learning with Bayesian methods, termed Big Bayesian Learning, including non-parametric Bayesian methods for adaptively inferring model complexity, regularized Bayesian inference for improving the flexibility via posterior regularization, and scalable algorithms and systems based on stochastic subsampling and distributed computing for dealing with large-scale applications. We also provide various new perspectives on the large-scale Bayesian modeling and inference. (Abstract)
