Deep Learning: Artificial Neural Networks with Python How To Learn Online

#artificialintelligence

This online course is designed to teach you how to create deep learning Algorithms in Python by two expert Machine Learning & Data Science experts. That's what we mean when we say that in this course we teach you the most cutting edge Deep Learning models and techniques. Thanks to Keras we can create powerful and complex Deep Learning models with only a few lines of code. By applying your Deep Learning model the bank may significantly reduce customer churn.


Who Made the News? Text Analysis using R, in 7 steps

@machinelearnbot

The dataset used for the analysis was obtained from Kaggle Datasets, and is attributed to UCI Machine Learning. Clean and pre-process the text by removing punctuations, removing "stop words" (a, the, and, …) using tm_map() function as shown below: Create wordclouds for Publisher "Reuters". The "color" option allows us to specify color palette, "rot.per" We create wordclouds for 2 more publishers (Celebrity Café & CBS_Local) as shown below. This dataset comes from the UCI Machine Learning Repository.


How the random forest algorithm works in machine learning

#artificialintelligence

If you are not aware of the concepts of decision tree classifier, Please spend some time on the below articles, As you need to know how the Decision tree classifier works before you learning the working nature of the random forest algorithm. Given the training dataset with targets and features, the decision tree algorithm will come up with some set of rules. In decision tree algorithm calculating these nodes and forming the rules will happen using the information gain and gini index calculations. In random forest algorithm, Instead of using information gain or gini index for calculating the root node, the process of finding the root node and splitting the feature nodes will happen randomly.


Profiting from Python & Machine Learning in the Financial Markets

@machinelearnbot

Equities, like genes, are influenced via a massive network of strong and weak hidden relationships shared between one another. One of my goals was to create long and short clusters of stocks or "basket clusters" I could use to hedge or just profit from. This would require an unsupervised machine learning approach to create clusters of stocks that would share strong and weak relationships with one another. Generating short basket clusters could be more profitable than long basket clusters.


UC Berkeley Releases Massive Dex-Net 2.0 Dataset

IEEE Spectrum Robotics Channel

The dataset consists of 6.7 million point object point clouds, accompanying parallel-jaw gripper poses, along with a robustness estimate of how likely it is that the grasp will be able to lift and carry the object, and now you can use it to train your own grasping system. Instead, Dex-Net 2.0 relies on "a probabilistic model to generate synthetic point clouds, grasps, and grasp robustness labels from datasets of 3D object meshes using physics-based models of grasping, image rendering, and camera noise." In other words, Dex-Net 2.0 leverages cloud computing to rapidly generate a large training set for a CNN, in "a hybrid of well-established analytic methods from robotics and Deep Learning," as Goldberg explains: The key to Dex-Net 2.0 is a hybrid approach to machine learning Jeff Mahler and I developed that combines physics with Deep Learning. Mahler: With the release we hope that other roboticists can replicate our training results to facilitate development of new architectures for predicting grasp robustness from point clouds, and to encourage benchmarking of new methods.


Neural Network R codes in Power BI Part2

#artificialintelligence

In this post I will show how to apply neural network in a scenario in R and how to see the results and hidden layers in a plot. As you can see in the below picture number 2,3 and 4,data is not in a same scale, we need to do some data normalization before applying any machine learning. Next, I am going to call a package for Neural network that has been used a lot, name as "neuralnet". The only changes is to add parameter "Hidden" to the neural net function (number 1).


Will Apache Spark Finally Advance Genomic Data Analysis?

@machinelearnbot

The last decade or so has shown massive advancements in the capabilities of storage and data processing like Apache Hadoop and as these big data technologies have grown, so have their uses. Cotton Seed, senior principal software engineer at Broad Institute said that he and his team use genomic research platform they built on Spark, leveraging its SQL querying function and its library of machine learning algorithms. Spark's speed and scalability for data mining and genomic data analysis have made it the number one player in genomics. Overall, Spark has given genomic data analysis the answer it's needed in running real time data seamlessly through a system and offering batch processing applications that are faster than any other platform out there.


Learning about the world through video – twentybn – Medium

#artificialintelligence

A few notable exceptions, like DeepMind's recently released Kinetics dataset, try to alleviate this by focusing on shorter clips, but since they show high-level human activities taken from YouTube videos, they fall short of representing the simplest physical object interactions that will be needed for modeling visual common sense. To generate the complex, labelled videos that neural networks need to learn, we use what we call "crowd acting". Predicting the textual labels from the videos therefore requires strong visual features that are capable of representing a wealth of physical properties of the objects and the world. The videos show human actors performing generic hand gestures in front of a webcam, such as "Swiping Left/Right," "Sliding Two Fingers Up/Down," or "Rolling Hand Forward/Backward."


Deep Learning with TensorFlow in Python

@machinelearnbot

Let's first learn about simple data curation practices, and familiarize ourselves with some of the data that are going to be used for deep learning using tensorflow. After preprocessing, let's peek a few samples from the training dataset and the next figure shows how it looks. Here is how the test dataset looks (a few samples chosen). Let's first train a simple LogisticRegression model from sklearn (using default parameters) on this data using 5000 training samples.


Visualizing Time-Series Change

@machinelearnbot

To evaluate the different methods for visualizing change, I chose to examine population data from the three major North American countries. The chart above shows population of the United States, Mexico, Canada, and North America as a whole (including Central America and the Caribbean). While plotting change in absolute units allows us to make comparisons within specific datasets, it is not particularly effective for comparing change across datasets with vastly different scales.
