Getting Started with Deep Learning


Editor's note: Please note that, while this chart and post was up to date when it was first published, the landscape has changed in such a way that the table below is not depict a fully accurate picture at this point (e.g. Keras now supports a greater number of frameworks). The post is still beneficial, however, with this caveat noted. At SVDS, our R&D team has been investigating different deep learning technologies, from recognizing images of trains to speech recognition. We needed to build a pipeline for ingesting data, creating a model, and evaluating the model performance.

Evolution of Neural Networks


Today, AI lives its golden age whereas neural networks make a great contribution to it. Previous applications such as AND, OR and OR logic functions are linear problems whereas XOR function is non-linear problem. He transforms the concept of neural networks to deep learning which includes too many hidden layers. Today, deep learning stands in back of most of challenging technologies such as speech recognition, image recognition, language translation.

Digital transformation: How machine learning could help change business 7wData


Machine learning (ML) based data analytics is rewriting the rules for how enterprises handle data. With minimal pre-task human efforts needed, the scalability of unsupervised machine learning is much higher. Supervised ML requires humans to create sets of training data and validate the results of the training. With minimal pre-task human efforts needed, the scalability of unsupervised ML (particularly in terms of the human workload upfront) is much higher.

Russia launches its own version of Amazon Alexa with 'near-human levels' of speech recognition


The Russian technology company Yandex has launched an artificial intelligence (AI) assistant called "Alice". Yandex, Russia's largest search engine, said in a press release Tuesday that Alice is the first conversational online assistant, possessing "near-human levels of speech." "We wanted Alice to interact with users more like a human, so that users don't need to adapt their requests," said Denis Filippov, head of speech technologies at Yandex. Based on word error rate (WER) measurements, Alice demonstrates near-human levels of speech recognition accuracy," Filippov added.

Using Amazon Polly to Provide Real-Time Home Monitoring Alerts Amazon Web Services


After the call is established, Twilio steps through the TwiML instructions and uses synthesized speech retrieved from Amazon Polly to start streaming to the customer. Call recipients respond by pressing buttons on their mobile phone keypad (DTMF codes). Depending on the DTMF codes, our service takes the specified action and returns the TwiML instructions for synthesized speech retrieval from Amazon Polly. We are planning to use Amazon Lex in the future, so that customers can issue controlled commands to their home security system instead of pressing DTML codes.

Ipsos Encyclopedia - Artificial Intelligence


Particular applications of AI include expert systems, speech recognition and machine vision (also referred as computer vision). There are three types of machine learning algorithms: supervised learning, in which data sets are labelled so that patterns can be detected and used to label new data sets; unsupervised learning, in which data sets aren't labelled and are sorted according to similarities or differences; and reinforcement learning, in which data sets aren't labelled but, after performing an action or several actions, the AI system is given feedback. Natural language processing (NLP) is the processing of human language by a computer program. Pattern recognition is a branch of machine learning that focuses on identifying patterns in data.

Cheap chips and simple AI could make voice recognition hardware disposable


Squeezing down, say, the AI that powers Amazon's AI assistant, Alexa, to run on simple battery-powered chips with clock speeds of just hundreds of megahertz isn't feasible. That's partly because Alexa has to interpret a lot of different sounds, but also because most voice recognition AIs use neural networks that are resource-hungry, which is why Alexa sends its processing to the cloud. The team's first attempts required eight million calculations to analyze a one-second clip of audio with 89 percent accuracy. Instead, he suggests that slightly high-power chips that can summon more of the linguistic capabilities of the kind found in Google Assistant and Amazon's Alexa may be better suited to consumer applications.

The Real Power of Artificial Intelligence


Periods of major technological advancement are often marked by alienation. Artificial intelligence is defined as the development of computer systems to perform tasks that normally require human intelligence, including speech recognition, visual perception, and decision-making. Machine learning has enabled the two biggest advances in artificial intelligence: perception and cognition. In a machine's case, perception refers to the ability to detect objects without being explicitly told and cognition refers to the ability to identify patterns to form new knowledge.

Promise of Deep Learning for Natural Language Processing - Machine Learning Mastery


The first promise for deep learning in natural language processing is the ability to replace existing linear models with better performing models capable of learning and exploiting nonlinear relationships. In his book expanding on deep learning for NLP, Yoav Goldberg comments that sophisticated neural network models like recurrent neural networks allow for wholly new NLP modeling opportunities. In the same initial lecture on deep learning for NLP, Chris Manning goes on to describe that deep learning methods are popular for natural language because they are working. A final promise of deep learning is the ability to develop and train end-to-end models for natural language problems instead of developing pipelines of specialized models.

Google now lets you mute an ad because it 'knew too much'


The search giant now lets you tell it as much through a muting tool built into each of its third-party display ads. That share includes display ads placed on millions of third-party sites through Google's various ad platforms. The company does now let you turn off or customize this sort of ad personalization in your account settings (Click your account avatar in the top right corner of a Google page, then "My Account," and "Ad settings" under "Personal info & privacy"). You can also block individual advertisers and ads on Google searches, YouTube, Gmail, and independent sites through the new built-in tools, which a Google spokesperson said the company added earlier this year.
