What is Deep Learning and how does it work?

#artificialintelligence

One of these is neural networks – the algorithms that underpin deep learning and play a central part in image recognition and robotic vision. Inspired by the nerve cells (neurons) that make up the human brain, neural networks comprise layers (neurons) that are connected in adjacent layers to each other. So we need to compile a training set of images – thousands of examples of cat faces, which we (humans) label "cat", and pictures of objects that aren't cats, labelled (you guessed it) "not cat". In 2001, Paul Viola and Michael Jones from Mitsubishi Electric Research Laboratories, in the US, used a machine learning algorithm called adaptive boosting, or AdaBoost, to detect faces in an image in real time.


Machine Learning vs. Statistics: The Texas Death Match of Data Science

@machinelearnbot

Both Statistics and Machine Learning create models from data, but for different purposes. In conclusion, the Statistician is concerned primarily with model validity, accurate estimation of model parameters, and inference from the model. In Machine Learning, the predominant task is predictive modeling: the creation of models for the purpose of predicting labels of new examples. In predictive analytics, the ML algorithm is given a set of historical labeled examples.


How Artificial Intelligence is Key to Making Real Estate Brokers Better cre.tech

#artificialintelligence

Those are the words of Andrew Bermudez, CEO and co-founder of Digsy AI, an AI powered prospecting automation platform for commercial real estate. "No one has ever been able to truly quantify what precise prospecting activities make a broker successful," he continued. To do that they must document every text, email and phone call through their system and collect every bit of data they can. One of the best quotes I got from Andrew was this: "Software can create efficiencies, but AI can find where the efficiencies can be created."


Applied Statistical Modeling for Data Analysis in R

@machinelearnbot

I created this course to take you by hand and teach you all the concepts, and take your statistical modeling from basic to an advanced level for practical data analysis. Frankly, this is the only one course you need to complete in order to get a head start in practical statistical modeling for data analysis using R. My course has 9.5 hours of lectures and provides a robust foundation to carry out PRACTICAL, real-life statistical data analysis tasks in R, one of the most popular and FREE data analysis frameworks. This course is your sure-fire way of acquiring the knowledge and statistical data analysis skills that I acquired from the rigorous training I received at 2 of the best universities in the world, perusal of numerous books and publishing statistically rich papers in renowned international journal like PLOS One. To be more specific, here's what the course will do for you: The course will mostly focus on helping you implement different statistical analysis techniques on your data and interpret the results.


Data Science: Deep Learning in Python - Udemy

#artificialintelligence

This course will get you started in building your FIRST artificial neural network using deep learning techniques. Following my previous course on logistic regression, we take this basic building block, and build full-on non-linear neural networks right out of the gate using Python and Numpy. You should take this course if you are interested in starting your journey toward becoming a master at deep learning, or if you are interested in machine learning and data science in general. If you already know about softmax and backpropagation, and you want to skip over the theory and speed things up using more advanced techniques along with GPU-optimization, check out my follow-up course on this topic, Data Science: Practical Deep Learning Concepts in Theano and TensorFlow.


Quant Trading using Machine Learning - Udemy

@machinelearnbot

The focus is on practically applying ML techniques to develop sophisticated Quant Trading models. Quant Trading: Quant Trading is a perfect example of an area where the use of Machine Learning leads to a step change in the quality of the models used. Traditional models often depend on Excel and building sophisticated models requires a huge amount of manual effort and domain knowledge. The only way to keep our prices this low is to *NOT offer additional technical support over email or in-person*.


Predict the future with Machine Learning

#artificialintelligence

Fundamentally it is Software that works like our brain, learning from information (data), then applying it to make smart decisions. Ok let's dive head first into the 3 major types of algorithms in the field of Machine Learning; Supervised learning, Unsupervised learning and Reinforcement learning. One common clustering technique is called "k-means clustering", which aims to solve clustering problems. Bayesian Networks utilise graphs, probability theory and statistics to model real-world situations and infer data insights.


Apple is now publishing a 'journal' with its cutting-edge machine learning research

#artificialintelligence

Very excited for the launch of Apple's Machine Learning blog: https://t.co/SLDpnhwgT5. For example, its Silicon Valley rival, Google, has a subsidiary, DeepMind, which is one of the leaders in a machine learning technology called deep learning or neural networks. Increasingly, interesting applications and techniques for machine learning have been published on ArXiv, a website that collects academic-style papers before they've been peer-reviewed. The first substantive post examines a way to generate simulated images to train a machine learning algorithm using a technique called generative adversarial networks.


What is Machine Learning?

#artificialintelligence

Machine learning is perhaps the principal technology behind two emerging domains: data science and artificial intelligence. Whether it's manufacturing or logistics, efficiency can be improved by automating components of the processes to improve the flow of goods. In these processing pipelines, manufacturing, logistics or data management, the overall pipeline normally also requires human intervention from an operator. In information processing settings these atoms require emulation of our cognitive skills.


Machine Learning at Scale with Spark

@machinelearnbot

The second lab provided WebServer Logs from NASA and asked students to parse the Apache Common Log Format, create Spark RDDs (that is Resilient Distributed Datasets), and analyze how many valid requests/responses (200X), how many failed, which resources failed and when! A TF-IDF (Term Frequency and Inverted Document Frequency) technique was used to compute similarity between documents of product descriptions. CF was combined with Alternating Least Squared techniques to make predictions of movie ratings. Finally, the lab asked the user to rate a small sample of movies to make personalized movie recommendations.
