Machine Learning and the Future of Music: An era of ML artists

#artificialintelligence

Artificial Intelligence has already taken over our lives and transformed it for the good. The days are over when you could still debate whether AI will impact a certain industry and transform it like others. Because artificial intelligence has already penetrated every other industry that we know and continues to impact several others. It is already being used in several ways, while others are under research. The only question we can think about is, how much will AI take over an existing industry and change it for the good?


SemEval-2017 Task 3: Community Question Answering

arXiv.org Artificial Intelligence

We describe SemEval-2017 Task 3 on Community Question Answering. This year, we reran the four subtasks from SemEval-2016:(A) Question-Comment Similarity,(B) Question-Question Similarity,(C) Question-External Comment Similarity, and (D) Rerank the correct answers for a new question in Arabic, providing all the data from 2015 and 2016 for training, and fresh data for testing. Additionally, we added a new subtask E in order to enable experimentation with Multi-domain Question Duplicate Detection in a larger-scale scenario, using StackExchange subforums. A total of 23 teams participated in the task, and submitted a total of 85 runs (36 primary and 49 contrastive) for subtasks A-D. Unfortunately, no teams participated in subtask E. A variety of approaches and features were used by the participating systems to address the different subtasks. The best systems achieved an official score (MAP) of 88.43, 47.22, 15.46, and 61.16 in subtasks A, B, C, and D, respectively. These scores are better than the baselines, especially for subtasks A-C.


Latent Replay for Real-Time Continual Learning

arXiv.org Machine Learning

Training deep networks on light computational devices is nowadays very challenging. Continual learning techniques, where complex models are incrementally trained on small batches of new data, can make the learning problem tractable even for CPU-only edge devices. However, a number of practical problems need to be solved: catastrophic forgetting before anything else. In this paper we introduce an original technique named ``Latent Replay'' where, instead of storing a portion of past data in the input space, we store activations volumes at some intermediate layer. This can significantly reduce the computation and storage required by native rehearsal. To keep the representation stable and the stored activations valid we propose to slow-down learning at all the layers below the latent replay one, leaving the layers above free to learn at full pace. In our experiments we show that Latent Replay, combined with existing continual learning techniques, achieves state-of-the-art accuracy on a difficult benchmark such as CORe50 NICv2 with nearly 400 small and highly non-i.i.d. batches. Finally, we demonstrate the feasibility of nearly real-time continual learning on the edge through the porting of the proposed technique on a smartphone device.


TX-Ray: Quantifying and Explaining Model-Knowledge Transfer in (Un-)Supervised NLP

arXiv.org Machine Learning

While state-of-the-art NLP explainability (XAI) methods focus on supervised, per-instance end or diagnostic probing task evaluation[4, 2, 10], this is insufficient to interpret and quantify model knowledge transfer during (un-) supervised training. By instead expressing each neuron as an interpretable token-activation distribution collected over many instances, one can quantify and guide visual exploration of neuron-knowledge change between model training stages to analyze transfer beyond probing tasks and the per-instance level. This allows one to analyze: (RQ1) how neurons abstract knowledge during unsupervised pretraining; (RQ2) how pretrained neurons zero-shot transfer knowledge to new domain data; and (RQ3) how supervised tasks reorder pretrained neuron knowledge abstractions. Since the meaningfulness of XAI methods is hard to quantify [11, 4], we analyze three example learning setups (RQ1-3) to empirically verify that our method (TX-Ray): identifies transfer (ir-)relevant neurons for pruning (RQ3), and that its transfer metrics coincide with traditional measures like perplexity (RQ1). We also find, that TX-Ray guided pruning of supervision (ir-)relevant neuron-knowledge (RQ3) can identify `lottery ticket'-like [9, 40] neurons that drive model performance and robustness. Upon inspecting pruned neurons, we find that task-relevant neuron-knowledge (`tickets'), appear (over-)fit, while task-irrelevant neurons lower overfitting, i.e. TX-Ray identifies neurons that generalize, transfer or specialize model-knowledge [25]. Finally, through RQ1-3, we find that TX-Ray helps to explore and quantify dynamics of (continual) knowledge transfer and that it can shed light on neuron-knowledge specialization and generalization, to complement (costly) supervised probing task procurement and established `summary' statistics like perplexity, ROC or F scores.


LOGAN: Latent Optimisation for Generative Adversarial Networks

arXiv.org Machine Learning

Training generative adversarial networks requires balancing of delicate adversarial dynamics. Even with careful tuning, training may diverge or end up in a bad equilibrium with dropped modes. In this work, we introduce a new form of latent optimisation inspired by the CS-GAN and show that it improves adversarial dynamics by enhancing interactions between the discriminator and the generator. We develop supporting theoretical analysis from the perspectives of differentiable games and stochastic approximation. Our experiments demonstrate that latent optimisation can significantly improve GAN training, obtaining state-of-the-art performance for the ImageNet ( 128 128) dataset. Our model achieves an Inception Score (IS) of 148 and an Fr echet Inception Distance (FID) of 3.4, an improvement of 17% and 32% in IS and FID respectively, compared with the baseline BigGAN-deep model with the same architecture and number of parameters. Generative Adversarial Nets (GANs) are implicit generative models that can be trained to match a given data distribution. GANs were originally developed by Goodfellow et al. (2014) for image data. As the field of generative modelling has advanced, GANs remain at the frontier, generating high-fidelity images at large scale (Brock et al., 2018).


Patchy Image Structure Classification Using Multi-Orientation Region Transform

arXiv.org Artificial Intelligence

Exterior contour and interior structure are both vital features for classifying objects. However, most of the existing methods consider exterior contour feature and internal structure feature separately, and thus fail to function when classifying patchy image structures that have similar contours and flexible structures. To address above limitations, this paper proposes a novel Multi-Orientation Region Transform (MORT), which can effectively characterize both contour and structure features simultaneously, for patchy image structure classification. MORT is performed over multiple orientation regions at multiple scales to effectively integrate patchy features, and thus enables a better description of the shape in a coarse-to-fine manner. Moreover, the proposed MORT can be extended to combine with the deep convolutional neural network techniques, for further enhancement of classification accuracy. V ery encouraging experimental results on the challenging ultra-fine-grained cultivar recognition task, insect wing recognition task, and large variation butterfly recognition task are obtained, which demonstrate the effectiveness and superiority of the proposed MORT over the state-of-the-art methods in classifying patchy image structures. Our code and three patchy image structure datasets are available at: https://github.com/XiaohanY


Towards Successful Collaboration: Design Guidelines for AI-based Services enriching Information Systems in Organisations

arXiv.org Artificial Intelligence

Information systems (IS) are widely used in organisations to improve business performance. The steady progression in improving technologies like artificial intelligence (AI) and the need of securing future success of organisations lead to new requirements for IS. This research in progress firstly introduces the term AI-based services (AIBS) describing AI as a component enriching IS aiming at collaborating with employees and assisting in the execution of work-related tasks. The study derives requirements from ten expert interviews to successful design AIBS following Design Science Research (DSR). For a successful deployment of AIBS in organisations the D&M IS Success Model will be considered to validated requirements within three major dimensions of quality: Information Quality, System Quality, and Service Quality. Amongst others, preliminary findings propose that AIBS must be preferably authentic. Further discussion and research on AIBS is forced, thus, providing first insights on the deployment of AIBS in organisations.


Optimality and limitations of audio-visual integration for cognitive systems

arXiv.org Artificial Intelligence

Multimodal integration is an important process in perceptual decision-making. In humans, this process has often been shown to be statistically optimal, or near optimal: sensory information is combined in a fashion that minimises the average error in perceptual representation of stimuli. However, sometimes there are costs that come with the optimization, manifesting as illusory percepts. We review audio-visual facilitations and illusions that are products of multisensory integration, and the computational models that account for these phenomena. In particular, the same optimal computational model can lead to illusory percepts, and we suggest that more studies should be needed to detect and mitigate these illusions, as artefacts in artificial cognitive systems. We provide cautionary considerations when designing artificial cognitive systems with the view of avoiding such artefacts. Finally, we suggest avenues of research towards solutions to potential pitfalls in system design. We conclude that detailed understanding of multisensory integration and the mechanisms behind audio-visual illusions can benefit the design of artificial cognitive systems.


Microsoft teamed up with Indigenous traditional owners in Kakadu, using AI and drones to rehabilitate parts of the national park

#artificialintelligence

Microsoft is blending Indigenous knowledge with AI to protect parts of Kakadu National Park. The tech behemoth partnered with the CSIRO and Indigenous rangers at the World Heritage-listed park to restore native wildlife using artificial intelligence (AI). Located in the Northern Territory, Kakadu is jointly managed by Parks Australia and traditional Indigenous owners. Its wetlands are home to protected Australian species such as magpie geese, which are considered by traditional custodians as a major indicator of'healthy country'. But the introduction of a weed called para grass has seen the reduction of native plants and has removed habitats for the magpie geese. Michael Douglas, leader of NESP Northern Australia Environmental Resources Hub, explained that para grass was planted in the area during the late 1960s before Kakadu was a national park, used as buffalo and cattle feed.


Does the healthcare industry lack tech talent? Waitematā doesn't think so - Wyndham Media

#artificialintelligence

TECHNOLOGIES such as artificial intelligence (AI), machine learning (ML), the internet of things (IoT), 5G, and robotics have plenty of potential in the healthcare space. However, most healthcare organizations are unable to leverage those technologies because they neither have the digital infrastructure nor the technology talent to turn their vision into real projects. "Health services have a lot to do before they can make the most of these opportunities," Waitematā District Health Board (DHB) Clinical Director Innovation Robyn Whittaker told Tech Wire Asia underscoring the fact that industry professionals aren't oblivious to the power that technology holds. Whittaker and her team at Waitematā DHB have just made it to the list of finalists in the talent accelerator category at the IDC Digital Transformation Awards. To prepare for the digital age, Whittaker's team is working on the foundational layers, digitizing data, and making it available for clinicians and researchers looking to make sense of that data.
