Deep Residual Networks for Image Classification with Python NumPy

#artificialintelligence

A description of the main concepts that permitted the goals achieved in the last decade, an introduction of image classification and object localization problems, ILSVRC and the models that obtained best results from 2012 to 2015 in both the tasks. This chapter contains an explanation on how to implement both forward and backward steps for each one of the layers used by the residual model, the residual model's implementation and some method to test a network before training. After developed the model and a solver to train it, I conducted several experiments with the residual model on CIFAR-10, in this chapter I show how I tested the model and how the behavior of the network changes when one removes the residual paths, applies data-augmenting functions to reduce overfitting or increases the number of the layers, then I show how to foil a trained network using random generated images or images from the dataset. Here I describe other results obtained training the same model on MNIST and SFDDD (check below for more infos), an overview of the project and possible future works with it. Below I describe in brief how I got all of that, the sources I used, the structure of the residual model I trained and the results I obtained. Please keep in mind that my first objective was to develop and train the model so I didn't spent much time on the design aspect of the framework, but I'm working on it (and pull requests are welcome)! When I started to think I wanted to implement "Deep Residual Networks for Image Recognition", on GitHub there was only this project from gcr, based on Lua Torch, this code really helped me a lot when I had to implement the residual model. Neural Networks and Deep Learning by Michael Nielsen contains a really well organized exhaustive introduction to the subject and a lot of code to help the user understand what is going on on each part of the process.


Is the IoT acting in the Right Interest? - Netopia

#artificialintelligence

A major concern for our rights as consumers is the way that machines direct us according to their interests and not ours. Experts such as Dr Jonathan Cave warn about the growing influence of software machines on our lives. Cave says that software machines will make use of what they know about us to present information to us which may not be to our advantage. Because the search engines that we have used know a certain amount about us and our previous buying decisions, they are keen to exploit that by turning us into a buyer of something, by a process known as'filter bubbles' โ€“ a feedback loop where recommendations only reinforce existing patterns. As Dr Rupp states'if you are not paying then you are not the customer'. Thus if you are not paying for an internet technology such as Google or Facebook it is not acting in your interests, but rather in the interests of the customers who are paying to present information to you.

Using neuroscience to create learning machines

#artificialintelligence

Most AI systems these days have a learning component to them, and I've touched on the ways in which systems learn a few times previously. One of the more interesting approaches aims to mimic the way humans learn. Such approaches have their roots in a theory that was first published in 1995, which suggested that learning is a two pronged approach. The first system acquires knowledge gradually based upon our exposure to new experiences. The second system then stores each of these experiences so that we can replay them and effectively integrate them.


Why Artificial Intelligence Will Never, Ever Destroy The World - Verboten Publishing - Articles

#artificialintelligence

Why Artificial Intelligence Will Never, Ever Destroy The World Production being based on opportunity relies on external reactions to create a cycle. Even the fastest machine often finds itself waiting. So even if an Artificial Intelligence emerged (which it won't I believe we'll just go straight to producing real digital intelligence), it will be bound by the same self constraining laws of consumption as any other organism. There won't be any doomsday, no sudden explosion of chaos as some malignant digital cancer concludes the pointlessness of man and begins an extermination. Instead the program will co-exist and compete, it will take chances and sometimes lose. Yes, even with perfect memory, trillions of cycles a second, and all available facts the machine will still face limits, because the Universe itself is infinitly more complex and energy intensive than any object granted elevated influence through better intelligence.


Trust issues? Use Trooly and machine learning to figure out who you may be working with

#artificialintelligence

You may think you're a great judge of character, but how much do you really know about someone after a single meeting? Despite the importance of trust in any relationship, business or otherwise, it can be hard to ascertain, especially in a short period of time. So to help you make better, more informed decisions about people you may want to work with, tech company Trooly has launched its Instant Trust rating service, which claims to help "businesses verify, screen, and predict trustworthy relationships and interactions." It's all based on machine learning and the wealth of information available within your digital footprint, and Trooly says it hopes to fill the "trust gap" that results from the "speed of modern commerce and community." Available to both businesses and consumers, Trooly uses data that is generally publicly available to better understand an individual's -- or a company's -- personality and behavior traits.


Artificial Self Deception

#artificialintelligence

With all the talk about A.I. what is missing is a definition of the I. Intelligence, I believe, is about self-awareness. We don't know what causes it. We can't isolate it for study. What we have in the works are systems to mimic the complexity of thought. To do that, we have to build in biases.


Fundamentals of Machine Learning for Predictive Data Analytics

#artificialintelligence

Machine learning is often used to build predictive models by extracting patterns from large datasets. These models are used in predictive data analytics applications including price prediction, risk assessment, predicting customer behavior, and document classification. This introductory textbook offers a detailed and focused treatment of the most important machine learning approaches used in predictive data analytics, covering both theoretical concepts and practical applications. Technical and mathematical material is augmented with explanatory worked examples, and case studies illustrate the application of these models in the broader business context. After discussing the trajectory from data to insight to decision, the book describes four approaches to machine learning: information-based learning, similarity-based learning, probability-based learning, and error-based learning.


Machine Learning Meta-analysis of Large Metagenomic Datasets: Tools and Biological Insights

#artificialintelligence

Shotgun metagenomic analysis of the human associated microbiome provides a rich set of microbial features for prediction and biomarker discovery in the context of human diseases and health conditions. However, the use of such high-resolution microbial features presents new challenges, and validated computational tools for learning tasks are lacking. Moreover, classification rules have scarcely been validated in independent studies, posing questions about the generality and generalization of disease-predictive models across cohorts. In this paper, we comprehensively assess approaches to metagenomics-based prediction tasks and for quantitative assessment of the strength of potential microbiome-phenotype associations. We develop a computational framework for prediction tasks using quantitative microbiome profiles, including species-level relative abundances and presence of strain-specific markers.


How a Technical Co-founder Spends his Time: Minute-by-minute Data for a Year

#artificialintelligence

I'm co-founder and CTO at Overleaf, a successful SaaS startup based in London. From August 2014 to December 2015, I manually tracked all of my work time, minute-by-minute, and analysed the data in R. Like most people who track their time, my goal was to improve my productivity. It gave me data to answer questions about whether I was spending too much or too little time on particular activities, for example user support or client projects. The data showed that my intuition on these questions was often wrong. There were also some less tangible benefits. It was reassuring on a Friday to have an answer to that usually rhetorical question, "where did this week go?" I feel like it also reduced context switching: if I stopped what I was doing to answer an chat message or email, I had to take the time to record it in my time tracker. I think this added friction was a win for overall productivity, perhaps paradoxically. This post documents the (simple) system I built to record my time, how I analysed the data, and the results.
