Deep Reinforcement Learning for AGV Routing

#artificialintelligence

This mapping will be included in an AGV Picking Simulation Model that will be used for testing our routing strategies. Dijkstra's algorithm is an optimization algorithm that solves the single-source shortest path problem for a directed graph with weighted edges (non-negative weights). This length can be the absolute length of the path, it can also be computed considering other constraints situated on the edges or the nodes. These parameters will vary in time, therefore let's use a reinforcement learning approach to select the optimal route from these candidates in accordance with this state.


Growing role for AI in fresh produce

#artificialintelligence

There is a growing role for artificial intelligence within horticulture, experts have claimed – but it is not the silver bullet many people think. Speaking at World of Fresh Ideas, Anthony Atlas, head of product and growth at agronomic machine-learning specialist ClimateAI, outlined the benefits and pitfalls of AI use on farms. Describing AI as "systems that generate predictions from past correlations – a giant pattern-identification machine", Atlas said AI is only as good as the training it receives. He stressed that it is not easy to build, and that there isn't one single system that does everything, but instead each task is done by a separate model trained to perform a particular task. In horticulture, AI is being used as a decision-support system in climate and weather forecasting, imagery interpretation and precision automation of greenhouses. Benefits of AI include more complexity, nuance and power, the ability to cheaply automate repetitive tasks, and the fact it is more lightweight than a supercomputer.


Artificial Intelligence for Rapid Exclusion of COVID-19 Infection

#artificialintelligence

An international retrospective study finds that infection with SARS-CoV-2, the virus that causes COVID-19, creates subtle electrical changes in the heart. An AI-enhanced EKG can detect these changes and potentially be used as a rapid, reliable COVID-19 screening test to rule out COVID-19 infection. The AI-enhanced EKG was able to detect COVID-19 infection in the test with a positive predictive value -- people infected -- of 37% and a negative predictive value -- people not infected -- of 91%. When additional normal control subjects were added to reflect a 5% prevalence of COVID-19 -- similar to a real-world population -- the negative predictive value jumped to 99.2%. The findings are published in Mayo Clinic Proceedings.


Random Forest Algorithm in Python from Scratch

#artificialintelligence

The intuition behind the random forest algorithm can be split into two big parts: the random part and the forest part. Let us start with the latter. A forest in real life is made up of a bunch of trees. A random forest classifier is made up of a bunch of decision tree classifiers (here and throughout the text -- DT). Each DT in an RF algorithm is completely independent of one another.


How to run (Model-Agnostic Meta-Learning) MAML algorithm

#artificialintelligence

MAML is a class of meta-learning algorithms created by Stanford Research and UC Berkeley Alum Dr. Chelsea Finn. MAML was inspired by the idea behind the question that how much data is really needed to learn about something. Can we teach algorithms to learn how to learn? Taken from Chelsea Finn's original research: MAML is designed such that it trains a model on a variety of tasks such that it can learn a new learning task with only a small number of training samples. MAML introduces an outer loop called meta-training.

Everything You Need To Know About Google's Vertex AI

#artificialintelligence

Alphabet CEO Sundar Pichai has introduced Vertex AI, a managed machine learning platform for deploying and maintaining AI models, during his keynote speech at the recently concluded Google I/O conference. The new platform brings AutoML and AI Platform together into a unified API, client library and user interface. "When we were training algorithms before, we would have to run millions of test images," said Jeff Houghton, chief operating officer of L'Oréal's ModiFace, which develops augmented reality and AI digital services for the beauty industry. "Now, we can rely on the Vertex technology stack to do the heavy lifting. Vertex has the computing power to figure out complex problems. It can do billions of iterations, and Vertex comes up with the best algorithms," Houghton added.


How to Build An Image Classifier in Few Lines of Code with Flash

#artificialintelligence

Image classification is a task where we want to predict which class belongs to an image. This task is difficult because of the image representation. If we flatten the image, it will create a long one-dimensional vector. Also, that representation will lose the neighbor information. Therefore, we need deep learning for extracting features and predict the result.


Understanding Seq2seq Models With Attention

#artificialintelligence

Here red appears before car in English whereas rouge(red) appears after voiture(car) in French. Not only in translation tasks model needs to understand the context properly even with QnA tasks, Text summarization, Image captioning and soon. This car is 2m in height -- so lean on my friend, 12m in width -- not very hug-able unfortunately, with a 8m wheelbase -- whatever use that information is for, a turning radius of just 0.1m -- making it easier to turn away from all your problems, a boot-space of 200 litres -- for all the luggage you'll carry for a trip and never use, a ground clearance of 0.25m -- in case you ever seek refuge under the car, a 6 cylinder engine with 5 valves -- a spec you'll only ever use while showing off and lastly has a dual overhead camshaft because big cars comes with big words. Here the model needs to memorize the numbers along with the corresponding features like height 2m, width 12m and soon and predict the answer based on the context it understood from the paragraph. Here context which is nothing but array of numbers, plays an important role in predicting the ouput sentence.


Here's How Ransomware Is Going To Fiendishly Impede AI Self-Driving Cars

#artificialintelligence

Ransomware will inevitably plague self-driving cars. Ransomware is being continually mentioned in the daily news and appears to be a seemingly unstoppable fiendish craze. Perhaps the recent attack of ransomware on the Colonial Pipeline received the most rapt attention since it led to concerns over gasoline shortages and caused quite a stir amongst the general public. When ransomware is used against a particular bank or hospital or school, this normally doesn't have quite the same widespread disruption as did the fuel pipeline incident. The thing is, we are probably going to see a lot more ransomware being fielded and doing so against all manner of businesses and governmental entities. Some would assert that we are only so far at the tip of the iceberg when it comes to ransomware hacks. Part of the reason why you can expect more use of ransomware is that it is relatively easy for an evildoer or crook to deploy the computer hacking scourge. Whereas the perpetrator used to need to have some keen computer nerdish skills, that's pretty much not the case anymore. Sadly, the ease of attempting to infect computer systems with ransomware has become nearly easy-peasy and has opened the floodgates to just about any determined villain to try (ransomware programs can be cheaply purchased online via the so-called dark web). There are now plentiful Ransomware-as-a-Service (RaaS) capabilities available that will do most of the heavy lifting for those that prefer a hands-off chauffeured form of ransomware cyberattacks.
