A Unified Framework for Speech Separation

arXiv.org Machine Learning

Speech separation refers to extracting each individual speech source in a given mixed signal. Recent advancements in speech separation and ongoing research in this area, have made these approaches as promising techniques for pre-processing of naturalistic audio streams. After incorporating deep learning techniques into speech separation, performance on these systems is improving faster. The initial solutions introduced for deep learning based speech separation analyzed the speech signals into time-frequency domain with STFT; and then encoded mixed signals were fed into a deep neural network based separator. Most recently, new methods are introduced to separate waveform of the mixed signal directly without analyzing them using STFT. Here, we introduce a unified framework to include both spectrogram and waveform separations into a single structure, while being only different in the kernel function used to encode and decode the data; where, both can achieve competitive performance. This new framework provides flexibility; in addition, depending on the characteristics of the data, or limitations of the memory and latency can set the hyper-parameters to flow in a pipeline of the framework which fits the task properly. We extend single-channel speech separation into multi-channel framework with end-to-end training of the network while optimizing the speech separation criterion (i.e., Si-SNR) directly. We emphasize on how tied kernel functions for calculating spatial features, encoder, and decoder in multi-channel framework can be effective. We simulate spatialized reverberate data for both WSJ0 and LibriSpeech corpora here, and while these two sets of data are different in the matter of size and duration, the effect of capturing shorter and longer dependencies of previous/+future samples are studied in detail. We report SDR, Si-SNR and PESQ to evaluate the performance of developed solutions.


Clarification: Health Care-Artificial Intelligence Story

#artificialintelligence

In a story Nov. 24, The Associated Press reported that an artificial intelligence program featuring a talking image of the Greek philosopher Aristotle is starting to help University of Southern California students cope with stress. The program's designers recently removed that image based on student feedback and are considering replacing it with another character.


What's the real end-game for AI music? Popgun's CEO has some ideas...

#artificialintelligence

There isn't this place in the world where teenagers come together to make music for each other. That place does not exist, and that's nuts! That thing needs to exist, and it will exist. And getting the AI working is the price of admission to build that thingโ€ฆ" Stephen Phillips, CEO of Australian startup Popgun, thinks that the early business models in this sector โ€“ AI-music as a replacement for production music, for example โ€“ are just a sliver of the ultimate potential for this technology. What's more, his thoughts on how AI music might disrupt the current music industry are less about people choosing to listen to AI-made music instead of human-made music, but rather about people (non-musicians) using AI tools to make music for one another. "Where's the'pop stars on training wheels' place where they make music for each other, release it and watch each other pretend to be pop stars, but then go on to become legitimate pop stars?


Greg Walters on real-world applications of GANs and PyTorch Packt Hub

#artificialintelligence

Introduced in 2014, GANs (Generative Adversarial Networks) was first presented by Ian Goodfellow and other researchers at the University of Montreal. It comprises of two deep networks, the generator which generates data instances, and the discriminator which evaluates the data for authenticity. GANs works not only as a form of generative model for unsupervised learning, but also has proved useful for semi-supervised learning, fully supervised learning, and reinforcement learning. In this article, we are in conversation with Greg Walters, one of the authors of the book'Hands-On Generative Adversarial Networks with PyTorch 1.x', where we discuss some of the real-world applications of GANs. According to Greg, facial recognition and age progression will one of the areas where GANs will shine in the future.

The Winding Road to Better Machine Learning Infrastructure Through Tensorflow Extended and Kubeflow

#artificialintelligence

As a result, our customers rarely have to build their own Docker containers, once again focusing less on infrastructure and more on their core use case. By having this controlled layer between the user and Kubeflow, we can easily manage upgrades of Kubeflow and TFX. We launched the alpha version of our platform in August and so far we have already seen about 100 users totaling 18,000 runs. Machine learning engineers can now focus on designing and analyzing their ML experiments instead of building and maintaining their own infrastructure, resulting in faster time from prototyping to production. In fact, early analysis indicates some teams are producing 7x more experiments already!



Edge compute creates exciting possibilities for emerging technology - SiliconANGLE

#artificialintelligence

Edge computing provides groundbreaking innovations to enterprise cloud organizations, including nearly instant code transfer, reduced latency, and enhanced performance. The lightning speed of edge compute is due to the placement of the platform. Unlike public cloud, edge compute is placed as close as possible to the point of interaction with humans, electronics, and various connected devices. Edge compute becomes more and more relevant to companies as applications evolve, including virtual reality, augmented reality, and video analytics, which rely on artificial intelligence. With real-time code transfer that AI needs to be extremely precise, and as AI evolves, every millisecond counts, according to Paul Savill (pictured), senior vice president of core network and technology solutions at CenturyLink Inc.



r/artificial - For Neuralink run tests to see if you can put thoughts into someone or something's head

#artificialintelligence

Easy enough to abstract information from someone's mind, but you'll know you're getting somewhere when you put information "in." Like maybe if you can get a monkey to "get the red ball" and they routinely do after having the thought put in their mind. Or for human trials have then be given a question they could know the answer to if the thought insertion worked. You shouldn't be trying to get a brain and a computer to work directly in tandem. Not at all compatible, but you can translate thoughts into computer code, have the computer do the processing and then insert the thought back.
