How Artificial Intelligence Will Impact The Insurance Industry

#artificialintelligence

That's because the insurance industry is one of the least innovative areas for customer experience, meaning that customers typically come away from their interactions disappointed and dissatisfied. However, things are definitely changing, and artificial intelligence is playing a large role. The fast-growing technology has the potential to disrupt the entire industry and greatly improve the insurance customer experience. The insurance agency is notorious for its outdated processes. Filing a claim often looks the same today as it did decades ago because the industry isn't consistently leveraging new technologies that are available to them.


The Step-By-Step PM Guide to Building Machine Learning Based Products

#artificialintelligence

It's time for every product manager, entrepreneur or business leader to get up to speed on machine learning. Even if you're not building the next chatbot or self driving car, you'll probably need to use machine learning in your product sooner rather than later to stay competitive. The good news is you don't need to invent the technology (though kudos if you do), just leverage what already exists. Tech companies have open sourced tools and platforms (Amazon AI, TensorFlow, originally developed by Google, and many others) that make machine learning accessible to virtually any company today. When I started in machine learning I knew next to nothing about it, yet in a relatively short time I was leading the development of products with machine learning at their very core (such as this).


Intro -- Starting AI w/ fast.ai โ€“ Wayne Nixalo โ€“ Medium

#artificialintelligence

I found www.fast.ai in April 2017 and was a bit blown away. An AI course focused on actually getting things done? I was just finishing Yaser Abu-Mostafa's CS1156x'Learning from Data' on edX, and while a great theoretical course, it did cut down a lot of my enthusiasm for Machine Learning. I guess learning to code in Python while writing Linear Regression models by hand has that effect. What really got me about Jeremy Howard's'Practical Deep Learning I' (which I'll call FAI01/FADL1) was that, over and over again, he'd explain a thing, you'd go do it, and all of a sudden you're catapulted to the forefront of applied ML.


Google's DeepMind create AI with an 'imagination'

Daily Mail - Science & tech

Google's DeepMind has revealed a radical new research project designed to give AI's an imagination. The breakthrough means that systems will be able to think about their actions, and undertake'deliberate reasoning.' The radical system uses an internal'imagination encoder' that helps the AI decide what are and what aren't useful predictions about its environment. The breakthrough means that systems will be able to think about their actions, and undertake'deliberate reasoning.' The agents use an'imagination encoder'- a neural network which learns to extract any information useful for the agent's future decisions, but ignore that which is not relevant.


SoftBank bags stake in Roomba maker IRobot as part of tech grab: sources

The Japan Times

LONDON/NEW YORK โ€“ SoftBank Group Corp. has taken a stake in Roomba vacuum-cleaner maker IRobot Corp., people familiar with the matter said, as the Japanese company builds its holdings in robotics firms. SoftBank has built a less than 5 percent stake in IRobot, below the amount that would require a regulatory disclosure in the U.S., the people said, asking not to be identified because the purchase was private. The Bedford, Massachusetts-based technology company has a market value of $2.4 billion. Shares in IRobot rose 22 percent in late trading in New York. Representatives for SoftBank and IRobot declined comment.


Prediction of amino acid side chain conformation using a deep neural network

arXiv.org Machine Learning

A deep neural network based architecture was constructed to predict amino acid side chain conformation with unprecedented accuracy. Amino acid side chain conformation prediction is essential for protein homology modeling and protein design. Current widely-adopted methods use physics-based energy functions to evaluate side chain conformation. Here, using a deep neural network architecture without physics-based assumptions, we have demonstrated that side chain conformation prediction accuracy can be improved by more than 25%, especially for aromatic residues compared with current standard methods. More strikingly, the prediction method presented here is robust enough to identify individual conformational outliers from high resolution structures in a protein data bank without providing its structural factors. We envisage that our amino acid side chain predictor could be used as a quality check step for future protein structure model validation and many other potential applications such as side chain assignment in Cryo-electron microscopy, crystallography model auto-building, protein folding and small molecule ligand docking.


A Robust Multi-Batch L-BFGS Method for Machine Learning

arXiv.org Machine Learning

This paper describes an implementation of the L-BFGS method designed to deal with two adversarial situations. The first occurs in distributed computing environments where some of the computational nodes devoted to the evaluation of the function and gradient are unable to return results on time. A similar challenge occurs in a multi-batch approach in which the data points used to compute function and gradients are purposely changed at each iteration to accelerate the learning process. Difficulties arise because L-BFGS employs gradient differences to update the Hessian approximations, and when these gradients are computed using different data points the updating process can be unstable. This paper shows how to perform stable quasi-Newton updating in the multi-batch setting, studies the convergence properties for both convex and nonconvex functions, and illustrates the behavior of the algorithm in a distributed computing platform on binary classification logistic regression and neural network training problems that arise in machine learning.


Dynamic Clustering Algorithms via Small-Variance Analysis of Markov Chain Mixture Models

arXiv.org Machine Learning

Bayesian nonparametrics are a class of probabilistic models in which the model size is inferred from data. A recently developed methodology in this field is small-variance asymptotic analysis, a mathematical technique for deriving learning algorithms that capture much of the flexibility of Bayesian nonparametric inference algorithms, but are simpler to implement and less computationally expensive. Past work on small-variance analysis of Bayesian nonparametric inference algorithms has exclusively considered batch models trained on a single, static dataset, which are incapable of capturing time evolution in the latent structure of the data. This work presents a small-variance analysis of the maximum a posteriori filtering problem for a temporally varying mixture model with a Markov dependence structure, which captures temporally evolving clusters within a dataset. Two clustering algorithms result from the analysis: D-Means, an iterative clustering algorithm for linearly separable, spherical clusters; and SD-Means, a spectral clustering algorithm derived from a kernelized, relaxed version of the clustering problem. Empirical results from experiments demonstrate the advantages of using D-Means and SD-Means over contemporary clustering algorithms, in terms of both computational cost and clustering accuracy.


DARLA: Improving Zero-Shot Transfer in Reinforcement Learning

arXiv.org Machine Learning

Domain adaptation is an important open problem in deep reinforcement learning (RL). In many scenarios of interest data is hard to obtain, so agents may learn a source policy in a setting where data is readily available, with the hope that it generalises well to the target domain. We propose a new multi-stage RL agent, DARLA (DisentAngled Representation Learning Agent), which learns to see before learning to act. DARLA's vision is based on learning a disentangled representation of the observed environment. Once DARLA can see, it is able to acquire source policies that are robust to many domain shifts - even with no access to the target domain. DARLA significantly outperforms conventional baselines in zero-shot domain adaptation scenarios, an effect that holds across a variety of RL environments (Jaco arm, DeepMind Lab) and base RL algorithms (DQN, A3C and EC).


Context-Independent Polyphonic Piano Onset Transcription with an Infinite Training Dataset

arXiv.org Machine Learning

Many of the recent approaches to polyphonic piano note onset transcription require training a machine learning model on a large piano database. However, such approaches are limited by dataset availability; additional training data is difficult to produce, and proposed systems often perform poorly on novel recording conditions. We propose a method to quickly synthesize arbitrary quantities of training data, avoiding the need for curating large datasets. Various aspects of piano note dynamics - including nonlinearity of note signatures with velocity, different articulations, temporal clustering of onsets, and nonlinear note partial interference - are modeled to match the characteristics of real pianos. Our method also avoids the disentanglement problem, a recently noted issue affecting machine-learning based approaches. We train a feed-forward neural network with two hidden layers on our generated training data and achieve both good transcription performance on the large MAPS piano dataset and excellent generalization qualities.
