Deep Learning
A Beginners Guide to Deep Learning โ #WeCoCreate โ Medium - Top Big Data News
In a deep network, there are many layers between the input and output (and the layers are not made of neurons but it can help to think of it that way), allowing the algorithm to use multiple processing layers, composed of multiple linear and non-linear Learning has revolutionized the machineโฆ These methods have dramaticallyimproved the state-of-the-art in speech recognition, visual object recognition, object detection and many other domains such as drug discovery and genomics. But, the ancient term "Deep Learning" was first introduced to Machine Learning by Dechter (1986)[10], and to Artificial Neural Networks (NNs) by Aizenberg et al (2000)[11]. It was further popularized by the development of Convolutional Networks Architecture by Alex Krizhevsky named'AlexNet' that won the competition of ImageNet in 2012 by defeating all the image processing methods and creating a way for deep learning architectures to be used in Image Processing.
Deep Learning in Multiple Multistep Time Series Prediction
The project aims to research on combining deep learning specifically Long-Short Memory (LSTM) and basic statistics in multiple multistep time series prediction. LSTM can dive into all the pages and learn the general trends of variation in a large scope, while the well selected medians for each page can keep the special seasonality of different pages so that the future trend will not fluctuate too much from the reality. A recent Kaggle competition on 145K Web Traffic Time Series Forecasting [1] is used to thoroughly illustrate and test this idea.
Bayesian Hypernetworks
Krueger, David, Huang, Chin-Wei, Islam, Riashat, Turner, Ryan, Lacoste, Alexandre, Courville, Aaron
We propose Bayesian hypernetworks: a framework for approximate Bayesian inference in neural networks. A Bayesian hypernetwork, $h$, is a neural network which learns to transform a simple noise distribution, $p(\epsilon) = \mathcal{N}(0,I)$, to a distribution $q(\theta) \doteq q(h(\epsilon))$ over the parameters $\theta$ of another neural network (the "primary network"). We train $q$ with variational inference, using an invertible $h$ to enable efficient estimation of the variational lower bound on the posterior $p(\theta | \mathcal{D})$ via sampling. In contrast to most methods for Bayesian deep learning, Bayesian hypernets can represent a complex multimodal approximate posterior with correlations between parameters, while enabling cheap i.i.d. sampling of $q(\theta)$. We demonstrate these qualitative advantages of Bayesian hypernets, which also achieve competitive performance on a suite of tasks that demonstrate the advantage of estimating model uncertainty, including active learning and anomaly detection.
Multiplicative LSTM for sequence modelling
Krause, Ben, Lu, Liang, Murray, Iain, Renals, Steve
We introduce multiplicative LSTM (mLSTM), a recurrent neural network architecture for sequence modelling that combines the long short-term memory (LSTM) and multiplicative recurrent neural network architectures. mLSTM is characterised by its ability to have different recurrent transition functions for each possible input, which we argue makes it more expressive for autoregressive density estimation. We demonstrate empirically that mLSTM outperforms standard LSTM and its deep variants for a range of character level language modelling tasks. In this version of the paper, we regularise mLSTM to achieve 1.27 bits/char on text8 and 1.24 bits/char on Hutter Prize. We also apply a purely byte-level mLSTM on the WikiText-2 dataset to achieve a character level entropy of 1.26 bits/char, corresponding to a word level perplexity of 88.8, which is comparable to word level LSTMs regularised in similar ways on the same task.
AI Is Changing The Way We Look At Data Science Abe
So how does deep learning deal with that? Well, when they asked me to define the neural models in a very compact way, I referred to the cat and dog problem and I just threw it. I said okay, "neural models learn to distinguish a dog from a cat just like the brain of a baby." What happens to the brain of a baby? We never explained what are the features of the cat, or the typical features of a dog.
Autonomous Delivery Demo Uses Nvidia AI Platform
A test fleet of autonomous delivery trucks scheduled for deployment next year will be outfitted with self-driving system based on Nvidia's AI processing technology for autonomous vehicles. The AI car computer called Drive PX will be combined with German automotive supplier ZF's self-driving platform in a fleet test planned by package delivery and logistics vendor Deutsche Post DHL Group (DPDHL). The goal is solving one of the biggest challenges for automating package delivery: getting deliveries the "last mile" between a central location to their final destination. The 2018 demonstration will use the package delivery company's (ETR: DPW) fleet of 3,400 electric delivery vehicles outfitted with cameras, radar and lidar (light detection and ranging). Sensor data is fed into an AI platform based on Drive PX.
How will we face being defeated by machines?
What can we learn from losing? That's the question at the heart of the documentary AlphaGo, about an AI program designed to play the ancient Chinese board game Go. The film follows AlphaGo and its creators, the Google-owned firm DeepMind, as the program defeats first the European champion, Fan Hui, then the legendary player Lee Se-dol. Fan and Lee are forced to answer this question as they're overwhelmed by AlphaGo's uncanny play style. And as artificial intelligence imitates more of the qualities we consider uniquely human, their conundrum is an important preview for the rest of us, who may soon be asking ourselves the very same things: What will do when a computer takes our jobs?
Now's the time for enterprises to do deep learning in the cloud
The AWS Re:invent conference is coming up, and predictions are starting to fly around what Amazon Web Services will announce there. A sure bet is that it will announce some sort of deep learning cloud service. Of course, Google, Microsoft, and IBM won't be far behind; indeed, both IBM and Microsoft have their own special deep learning projects in the works, called Brainwave and Distributed Deep Learning, respectively. Simply put, machine learning typically deals with tactical applications of AI, such as making instant predictions. Deep learning provides a foundation for the understanding of massive amounts of patterns or data.
The Rise of Artificial Intelligence through Deep Learning: Yoshua Bengio โ Artificial Intelligence and Magnificent Brain
A revolution in AI is occurring thanks to progress in deep learning. How far are we towards the goal of achieving human-level AI? What are some of the main challenges ahead? Yoshua Bengio believes that understanding the basics of AI is within every citizen's reach. That democratizing these issues is important so that our societies can make the best collective decisions regarding the major changes AI will bring, thus making these changes beneficial and advantageous for all.
