Activation Functions in Deep Neural Networks

#artificialintelligence

In order to understand the importance of activation functions, we must first recap how a neural network computes a prediction/output. This is generally referred to as Forward Propagation. During forward propagation, the neural network receives an input vector x and outputs a prediction vector y. Each layer of the network is connected via a so-called weight matrix with the next layer. In total, we have 4 weight matrices W1, W2, W3, and W4.


Way beyond AlphaZero: Berkeley and Google work shows robotics may be the deepest machine learning of all

ZDNet

The seemingly simple task of grasping an object from a large cluster of different kinds of objects is "one of the most significant open problems in robotics," according to Sergey Levine and collaborators. Grasping is a good example of problems that bedevil real-world machine learning, including latency that throws off the expected order of events, and goals that may be difficult to specify. The vast majority of artificial intelligence has been developed in an idealized environment: a computer simulation that dodges the bumps of the real world. Be it DeepMind's AlphaMu program for Go and chess and Atari or OpenAI's GPT-3 for language generation, the most sophisticated deep learning programs have all benefitted from a pruned set of constraints by which software is improved. For that reason, the hardest and perhaps the most promising work of deep learning may lie in the realm of robotics, where the real world introduces constraints that cannot be fully anticipated.


[N] Mastering PyTorch - hands on deep learning with PyTorch is on Amazon

#artificialintelligence

I recently wrote a book on deep learning - Mastering PyTorch which is now available on Amazon. It is an applied deep learning book with tons of exercises on training, testing, deploying, interpreting .. various kinds of deep learning models, using PyTorch. If you want to get hands-on proficiency in deep learning, this book can be a good resource. I have tried to keep the contents easy to grasp while retaining all the essential technical concepts.If you do get a copy, please let me know how you found it, and possibly leave an Amazon review. You can also read a synopsis of the book here.


Bioinformatics tool accurately tracks synthetic DNA

#artificialintelligence

A Rice University computer science lab challenges -- and beats -- deep learning in a test to see if a new bioinformatics approach effectively tracks the lab of origin of a synthetic genetic sequence.


What Is Deep Learning and what is Artificial Neural Networking…

#artificialintelligence

Deep learning is an Artificial intelligence function that imitates the workings of the human brain in processing data and creating patterns for use in decision making. Deep learning is a subset of machine learning in artificial intelligence that has networks capable of learning unsupervised from data that is unstructured or unlabeled. Also known as deep neural learning or deep neural network. Deep learning is an AI function that mimics the workings of the human brain in processing data for use in detecting objects, recognizing speech, translating languages, and making decisions. Deep learning AI is able to learn without human supervision, drawing from data that is both unstructured and unlabeled.


Amazon makes Alexa Conversations generally available

ZDNet

Amazon on Monday announced the general availability of Alexa Conversations, a deep learning-based dialog manager for the Alexa Skills Kit. The tool, first introduced in preview in 2019, helps developers create more natural conversations with customers. "Natural language is actually a very difficult thing to emulate," Nedim Fresko, Amazon's VP of Alexa Devices and Developer Technologies, told ZDNet last year. "When people speak naturally, they change direction, they make contextual references to things they said. Sometimes they over-supply information, sometimes they under-supply it -- when that happens, consumers revert to robotic language and simple phrases, and developers just give up."


Train Your Custom Deep Learning Model in AWS SageMaker

#artificialintelligence

If you are someone like me who does not want to setup an at home server to train your Deep Learning model, this article is for you. Likely, cloud-based Machine Learning infrastructures are your options. I will go over the step-by-step process of how to do this in AWS SageMaker. Amazon SageMaker comes with a good number of pre-trained models. These models are prebuilt docker images in AWS.


Fast Oriented Text Spotting with a Unified Network (FOTS)

#artificialintelligence

Text detection and recognition (also known as Text Spotting) from an image is a very useful and challenging problem that deep learning researchers have been working on since many years because of its practical applications in fields like document scanning, robot navigation and image retrieval, etc. Almost all the methods consisted of two separate stages so far: 1) Text detection 2) Text recognition. Text detection just finds out where the text is located in the given image and on these results, text recognition actually recognizes the characters from the text. Because of these two stages, two separate models were required to be trained and hence prediction time was a bit higher. Because of higher test time, the models were not suitable for real time applications. Contrary to this, FOTS solves this two stage problem using a unified end to end trainable model/network by detecting and recognizing text simultaneously.

Applications of Artificial Intelligence for Retinopathy of Prematurity Screening - Docwire News

#artificialintelligence

OBJECTIVES: Childhood blindness from retinopathy of prematurity (ROP) is increasing as a result of improvements in neonatal care worldwide. We evaluate the effectiveness of artificial intelligence (AI)-based screening in an Indian ROP telemedicine program and whether differences in ROP severity between neonatal care units (NCUs) identified by using AI are related to differences in oxygen-titrating capability. All images were assigned an ROP severity score (1-9) by using the Imaging and Informatics in Retinopathy of Prematurity Deep Learning system. We calculated the area under the receiver operating characteristic curve and sensitivity and specificity for treatment-requiring retinopathy of prematurity. Using multivariable linear regression, we evaluated the mean and median ROP severity in each NCU as a function of mean birth weight, gestational age, and the presence of oxygen blenders and pulse oxygenation monitors.
