AI news: Neural network learns when it should not be trusted - '99% won't cut it'

#artificialintelligence

Mr Amini said: "It was very calibrated to the errors that the network makes, which we believe was one of the most important things in judging the quality of a new uncertainty estimator." The test revealed the network's ability to flag when users should not place full trust in its decisions. In such examples, "if this is a health care application, maybe we don't trust the diagnosis that the model is giving, and instead seek a second opinion," Amini added. Dr Raia Hadsell, a DeepMind artificial intelligence researcher not involved with the workDeep evidential describes regression as "a simple and elegant approach that advances the field of uncertainty estimation, which is important for robotics and other real-world control systems. She added: "This is done in a novel way that avoids some of the messy aspects of other approaches -- [for example] sampling or ensembles -- which makes it not only elegant but also computationally more efficient -- a winning combination."


Vision-based fire detection facilities work better under new deep learning model

#artificialintelligence

Fast and accurate fire detection is significant to the sustainable development of human society and Earth ecology. The existence of objects with similar characteristics to fire increases the difficulty of vision-based fire detection. Improving the accuracy of fire detection by digging deeper visual features of fire always remains challenging. Recently, researchers from the Institute of Acoustics of the Chinese Academy of Sciences (IACAS) have proposed an efficient deep learning model for fast and accurate vision-based fire detection. The model is based on multiscale feature extraction, implicit deep supervision, and channel attention mechanism. The researchers utilized the real-time acquired image as the input of the model and normalized the image.


Deep Learning: Advanced NLP and RNNs

#artificialintelligence

It's hard to believe it's been been over a year since I released my first course on Deep Learning with NLP (natural language processing). A lot of cool stuff has happened since then, and I've been deep in the trenches learning, researching, and accumulating the best and most useful ideas to bring them back to you. So what is this course all about, and how have things changed since then? In previous courses, you learned about some of the fundamental building blocks of Deep NLP. We looked at RNNs (recurrent neural networks), CNNs (convolutional neural networks), and word embedding algorithms such as word2vec and GloVe.


What's happening in my LSTM layer?

#artificialintelligence

In building a deep neural network, especially using some of the higher level frameworks such as Keras, we often don't fully understand what's happening in each layer. The sequential model will get you far indeed, but when it's time to do something more complex or intriguing, you will need to dive into the details. In this article, I'm going to explain exactly what's happening as you pass a batch of data through an LSTM layer with an example from PyTorch. I want to note that, I won't be covering any of the exact mechanics of the LSTM cells or why they are useful. If you're reading this, you're probably aware of the vanishing gradient problem and understand the basics of the gating mechanisms.


Opensource: The magic power of AI research.

#artificialintelligence

PyTorch Lightning has its humble beginnings as a project that I developed during the first few years of my Ph.D. at NYU CILVR and later at Facebook AI Research. At NYU it gained the powers of rapid iteration and standardization that makes Lightning a pleasure to work with today -- it standardizes AI research code so everyone's code can be formatted the same way, and thus it becomes more readable and reproducible. At FAIR it learned how to train massive neural networks across hundreds of GPUs. But had I remained the only developer of the project it would be nowhere near where it is today as a quickly rising favorite for deep learning research. Our first non-facebook contributor Jirka, forced much-needed formatting and structuring to the internals.


Artificial Intelligence Neural Network Learns When It Should Not Be Trusted

#artificialintelligence

MIT researchers have developed a way for deep learning neural networks to rapidly estimate confidence levels in their output. The advance could enhance safety and efficiency in AI-assisted decision making. A faster way to estimate uncertainty in AI-assisted decision-making could lead to safer outcomes. Increasingly, artificial intelligence systems known as deep learning neural networks are used to inform decisions vital to human health and safety, such as in autonomous driving or medical diagnosis. These networks are good at recognizing patterns in large, complex datasets to aid in decision-making.


Building a One-shot Learning Network with PyTorch

#artificialintelligence

Deep learning has been quite popular for image recognition and classification tasks in recent years due to its high performances. However, traditional deep learning approaches usually require a large dataset for the model to be trained on to distinguish very few different classes, which is drastically different from how humans are able to learn from even very few examples. Few-shot or one-shot learning is a categorization problem that aims to classify objects given only a limited amount of samples, with the ultimate goal of creating a more human-like learning algorithm. In this article, we will dive into the deep learning approaches to solving the one-shot learning problem by using a special network structure: Siamese Network. We will build the network using PyTorch and test it on the Omniglot handwritten character dataset and performed several experiments to compare the results of different network structures and hyperparameters, using a one-shot learning evaluation metric.

How to Use Google Cloud and GPU Build Simple Deep Learning Environment

#artificialintelligence

Google Cloud Platform provides us with a wealth of resources to support data science, deep learning, and AI projects. Now all we need to care about is how to design and train models, and the platform manages the rest tasks. In current pandemic environment, the entire process of an AI project from design, coding to deployment, can be done remotely on the Cloud Platform. IMPORTANT: If you get the following notification when you create a VM that contains GPUs. You need to increase your GPU quota.


What is Artificial Intelligence? It's Applications and Importance

#artificialintelligence

The term artificial intelligence was initially revealed in 1956, yet AI has become more mainstream today on account of expanded data volumes, progressed algorithms, and enhancements in computing power and storage. During the 1960s, the US Department of Defense checked out this kind of work and started training computers to emulate fundamental human reasoning. For instance, the Defense Advanced Research Projects Agency (DARPA) finished road planning projects during the 1970s. What's more, DARPA created intelligent personal assistants in 2003, some time before Siri, Alexa or Cortana were easily recognized names. Artificial intelligence (AI), is the capacity of a digital computer or computer-controlled robot to perform activities usually connected with smart creatures.
