Robust AI: Protecting neural networks against adversarial attacks

#artificialintelligence

In its latest annual report, filed with the Securities and Exchange Commission, tech giant Alphabet warned investors against the many challenges of artificial intelligence, following the lead of Microsoft, which issued similar warnings last August. Recent advances in deep learning and neural networks have created much hope about the possibilities that AI presents to various domains that were previously thought to be off the limits for computer software. But there's also concern about new threats AI will pose to different fields, especially where bad decisions can have very destructive results. We've already seen some of these threats manifest themselves in various ways, including biased algorithms, AI-based forgery and the spread of fake news during important events such as elections. The past few years have seen the development of a growing discussion around building trust in artificial intelligence and creating safeguards that prevent abuse and malicious behavior of AI models.


AI researchers debate the ethics of sharing potentially harmful programs

#artificialintelligence

A recent decision by research lab OpenAI to limit the release of a new algorithm has caused controversy in the AI community. The nonprofit said it decided not to share the full version of the program, a text-generation algorithm named GPT-2, due to concerns over "malicious applications." But many AI researchers have criticized the decision, accusing the lab of exaggerating the danger posed by the work and inadvertently stoking "mass hysteria" about AI in the process. The debate has been wide-ranging and sometimes contentious. It even turned into a bit of a meme among AI researchers, who joked that they've had an amazing breakthrough in the lab, but the results were too dangerous to share at the moment.

Global AI in healthcare Market: Key Geographic Segment Based on region, the AI in healthcare market is divided into North America, Europe, Asia-Pacific, and LAMEA. North America accounted for the largest market share in the AI in healthcare market in 2016, and is expected to retain its dominance throughout the forecast period.


Natural Language-Focused AI From OpenAI Shows Promise, Creates Stories With Humor

#artificialintelligence

Is it possible that an AI could exist or will exist in the near future that is too dangerous to release as open source and should not be uploaded to the public or even released even within companies' private networks? Were movies like Tron, Matrix, Terminators and others warning us of such a scenario? Surprisingly such a dangerous AI algorithm may already exist although for now it focuses on text and natural language processing. Click here to view original webpage at www.forbes.com


What Are Hyperparameters And How Do They Determine A Model's Performance - Analytics India Magazine

#artificialintelligence

A key balancing act in machine learning is choosing an appropriate level of model complexity: if the model is too complex, it will fit the data used to construct the model very well but generalise poorly to unseen data (overfitting); if the complexity is too low the model won't capture all the information in the data (underfitting). In deep learning or machine learning scenarios, model performance depends heavily on the hyperparameter values selected. The goal of hyperparameter exploration is to search across various hyperparameter configurations to find a configuration that results in the best performance. Typically, the hyperparameter exploration process is painstakingly manual, given that the search space is vast and evaluation of each configuration can be expensive. The model parameters tell how to transform input data into desired output whereas, the hyperparameters are used to determine the structure of the model in use.


Infographic: 10 companies hiring the most AI talent

Demand for workers in artificial intelligence (AI) has increased by up to 119% in the past three years, with AI related roles nearly doubling, according to an RS Components report. By analyzing job posts from the world's biggest tech companies, the report revealed the organizations with the highest percentage of AI-related job openings. SEE: IT leader's guide to deep learning (Tech Pro Research) Contrary to popular belief, AI isn't replacing humans in tech; rather, at this point, it is creating more jobs. By eliminating time-consuming manual tasks, automation allows humans to spend more time on productive initiatives. Microsoft has the most open AI jobs available currently, totaling 1,964 positions, which is 36% of all open jobs at the company, the report found.


The Deep Learning AI Playbook: Strategy for Disruptive Artificial Intelligence: Carlos E Perez: 9781978487529: Amazon.com: Books

#artificialintelligence

NOTE TO PROSPECTIVE BUYERS: Save your money and read the Intuition Machine blog on Medium. It's free, and most of the material from this book is just compiled from the author's blog posts. Pros: 1) Thought-provoking survey of ideas at the forefront of AI research Cons: 1) The book is full of glaring grammatical errors that an editor should have caught. This makes whole sections of the book incomprehensible on the first pass. I know this because there are chapters where the author fails to remove lines such as "in this post..." Bottom line: the book lacks polish and, as such, is way overpriced.


Generalized Language Models

#artificialintelligence

As a follow up of word embedding post, we will discuss the models on learning contextualized word vectors, as well as the new trend in large unsupervised pre-trained language models which have achieved amazing SOTA results on a variety of language tasks. I guess they are Elmo & Bert? (Image source: here) We have seen amazing progress in NLP in 2018. Large-scale pre-trained language modes like OpenAI GPT and BERT have achieved great performance on a variety of language tasks using generic model architectures. The idea is similar to how ImageNet classification pre-training helps many vision tasks (*). Even better than vision classification pre-training, this simple and powerful approach in NLP does not require labeled data for pre-training, allowing us to experiment with increased training scale, up to our very limit. In my previous NLP post on word embedding, the introduced embeddings are not context-specific -- they are learned based on word concurrency but not sequential context.


Machine learning and therapeutics 2.0: Avoiding hype, realizing potential

#artificialintelligence

Clarifying the elements of an algorithm--and their distinctive impact--will be increasingly important if machine learning is to overcome skepticism among healthcare stakeholders. Machine learning algorithms must offer insights that are credible and aligned with the scientific or clinical consensus. An algorithm that fails to replicate established findings or counters the established body of evidence is more likely an indication of a methodological oversight or a data artifact than a truly novel insight. A pharmaceutical manufacturer recently described a scenario in which a machine learning algorithm concluded that reducing low-density lipoprotein cholesterol after a heart attack was not associated with cardiac outcomes. This finding does not change 20-plus years of established clinical science, but rather speaks to nuances in the data and analytic structure. Without such a context, machine learning could conclude that cigarette lighters cause lung cancer. This context is provided by domain-specific expertise. Its absence results in decisions that, while analytically sound, produce algorithms that are not likely to be adopted. For instance, a recent machine learning algorithm to predict cardiovascular events included "lack of data" as a key risk factor.12


Deep Learning for Natural Language Processing (NLP) โ€“ using RNNs & CNNs

#artificialintelligence

Wouldn't it be cool if a computer could understand the actual human sentiment behind sarcastic texts that can sometimes even trump actual humans? Or what if computers could understand a human language so well that it can estimate a probability telling you how likely it is to encounter any random sentence that you give it? Or maybe it could generate completely fake code snippets of the Linux kernel that look so authentic that they are just as intimidating as the actual source code (well, unless you are a kernel programmer yourself)? What if computers could immaculately translate English to French or over 100 languages from all over the world? Or "see" an image and describe the items found in the photo?
