Posted on by Dexlab

How AI is Powering Manufacturing in 2020

The world has seen a transformation in its economic activities since the coronavirus pandemic broke out. Economies have come to a grinding halt and manufacturing has dipped. Now what nations need is resilience and strength to carry on production in all sectors. What they are most depending on is the power of Artificial Intelligence to enhance the manufacturing process and help save money and drive down costs.

Here are some examples of how AI is powering the manufacturing sector in 2020.

  • AI is being used to transform machinery maintenance and quality in manufacturing operations today, according to Capgemini.
  • Caterpillar’s Marine Division is using machine learning to analyze data on how often its shipping equipment should be cleaned helping it save thousands of dollars.
  • The BMW Group is using AI to study manufacturing component images in and spot deviations from the standard production procedure in real-time.

In fact, a study shows that in the four earlier global economic downturns companies using AI were actually successful in increasing both sales and profit margins. Companies are all striving to utilize human experience, insights and AI techniques to give manufacturing a fillip in these times of a crisis.

Manufacturing using AI in real-time

Real-time monitoring of the manufacturing process is advantageous because it translates to sorting out production bottlenecks, tracking scrap rates and meeting customer deadlines among other things. The huge cache of data used can be utilized to build machine learning models.

Supervised and unsupervised machine learning algorithms can study multiple production shifts’ real-time data within seconds and predict processes, products, and workflow patterns that were not known before. A report  suggests 29% of AI implementations in manufacturing are for maintaining machinery and production assets.

Detecting Outages

It was found that the most popular use of AI in manufacturing is predicting when equipment are likely to fail and suggesting optimal times to conduct maintenance. Companies like General Motors analyze images of its robots from cameras mounted above to spot anomalies and possible failures in the production line and thus preempt outages.

Optimizing Design

General Motors uses AI algorithms to give and produce optimized product design. General Motors can achieve the goal of rapid prototyping with the help of AI and ML algorithms. Designers provide definitions of the functional needs, raw materials, manufacturing methods and other constraints and the company along with AutoDesk has customized Dreamcatcher to optimize for weight and other vital criterion. In this way, AI comes together with human endeavor to produce a-class product designs that cost lesser.

Data Science Machine Learning Certification

Inconsistencies

Nokia has begun using a video application that takes the help of machine learning to alert an assembly operator if there are inconsistencies in the production process in one of its factories in Oulu, Finland. It alerts a machine operator about inconsistencies in the production of electronic items and this helps preempt poor production process and helps the company save on a lot of money and capital.

There are many other production processes AI is helping revolutionize. Only time will tell how much of AI will power the manufacturing sector. But this technological advancement is surely making an impact on economies worldwide. Meanwhile, for more details, do peruse the DexLab Analytics website.

Stacking Regressor – Latest Releases of Scikit-Learn 0.22

Posted on by Dexlab

Stacking Regressor - Latest Releases of Scikit-Learn 0.22

Today we are going to learn about the new releases from Scikit-learn version 0.22, a machine learning library in Python. First we learn how to install it on our systems. Then, we come to the much talked about new release called stacking regression.

Now, how does stacking regression work? Well, you have been using machine learning algorithms like Decision Tree or Random Forest. Have you heard of Voter Classifier? It is an algorithm in Scikit-learn. Ensemble algorithm is a combination of two or more algorithms to make it stronger.

When working on a set of data, we must apply all these algorithms to get predicted values. Then we vote out classified predicted values in Voter Classifier. Stacking Classifier is different. What we are doing in it is stacking together the predicted values to make a new input.

Initially, we make prediction by using various algorithms separately. Their results or output are then concatenated together. Then we use this output as a new input and apply the algorithms to it to get target variable. This method is known as stacking regression.

We try this out on a data set that can be taken from a github repository the link to which is given below.

 

Then we use two algorithms as estimators. Then we use stacking regression to build a model. For more on this do watch the video attached herewith. This tutorial was brought to you by DexLab Analytics. DexLab Analytics is a premiere Machine Learning institute in Gurgaon.

5 Chatbots You Should Know About

Chatbots or “conversational agents” are software applications that mimic or imitate written or spoken human speech for the purposes of facilitating a conversation or interaction with a human being.

These applications have become one of the most ubiquitous software applications out there with the advancement of machine learning technology and NLP.

“Today’s chatbots are smarter, more responsive, and more useful – and we’re likely to see even more of them in the coming years… chatbots are used most commonly in the customer service space, assuming roles traditionally performed by living, breathing human beings such as Tier-1 support operatives and customer satisfaction reps.”

Conversational agents are becoming a common occurrence partly due to the fact that barriers to entry in creating chatbots such as sophisticated programming knowledge have become redundant.

How Chatbots work

The crux of chatbot technology is natural language processing or NLP, the same technology “that forms the basis of the voice recognition systems used by virtual assistants such as Google Now, Apple’s Siri, and Microsoft’s Cortana.” “Chatbots process the text presented to them by the user…infer what they mean and/or want, and determine a series of appropriate responses based on this information.”

Here are 5 companies using chatbots for various roles like marketing, communicating with marginalized groups and patients suffering from sleeplessness and memory loss.

Endurance

Russian technology company Endurance developed a companion chatbot to help dementia patients cope with decreased verbal ability. Many patients with Alzheimer’s disease use the chatbot to converse with. In turn, the chatbot identifies deviations in conversational patterns of the patient that might indicate a problem with memory and recollection.

Casper

Casper’s Insomnobot 3000 is a conversational agent that aims to help insomniacs by posing as a companion to talk to while the rest of the world sleeps. However, at this point, “Insomnobot 3000 is a little rudimentary.”

UNICEF

International child advocacy nonprofit UNICEF is using chatbots to help people living in developing countries speak out about the most urgent needs in their communities. The bot, named U-Report, focuses on large-scale data gathering via polls. UNICEF then uses feedback as the basis for potential policy recommendations.

MedWhat

This chatbot aims at making medical diagnoses faster, easier, and more transparent for both patients and physicians. MedWhat is powered by a highly sophisticated machine learning system that offers increasingly accurate responses to user questions based on behaviors that it “learns” by interacting with human beings. Also, it acts as a repository of a vast source of medical journals and medical advice.

Data Science Machine Learning Certification

Roof Ai

Roof Ai is a chatbot that helps real-estate marketers to “automate interacting with potential leads and lead assignment via social media”. The bot identifies potential leads via social media and responds immediately, irrespective of the time of the day. “Based on user input, Roof Ai prompts potential leads to provide a little more information, before automatically assigning the lead to a sales agent.”

Top Six Applications of Natural Language Processing (NLP)

Posted on by Dexlab

Top Six Applications of Natural Language Processing (NLP)

Words are all around us – in the form of spoken language, texts, sound bytes and even videos. The world would have been a chaotic place had it not been for words and languages that help us communicate with each other.

Now, if we were to enhance language with the attributes of artificial intelligence, we would be working with what is known as Natural Language Processing or NLP – the confluence of artificial intelligence and computational linguistics.

In other words, “NLP is the machine’s ability to process what was said to it, structure the information received, determine the necessary response and respond in a language that we understand”.

Here is a list of popular applications of NLP in the modern world.

1. Machine Translation

When a machine translates from one language to another, “we deal with “Machine” Translation. The idea behind MT is simple — to develop computer algorithms to allow automatic translation without any human intervention. The best-known application is probably Google Translate.”

2. Voice and Speech Recognition

Though voice recognition technology has been around for 50 years, it is only in the last few decades, owing to NLP, have scientists achieved significant success in the field. “Now we have a whole variety of speech recognition software programs that allow us to decode the human voice,”be it in mobile telephony, home automation, hands-free computing, virtual assistance and video games.

3. Sentiment Analysis

“Sentiment analysis (also known as opinion mining or emotion AI) is an interesting type of data mining that measures the inclination of people’s opinions. The task of this analysis is to identify subjective information in the text”. Companies use sentiment analysis to keep abreast of their reputation and customer satisfaction.

4. Question Answering

Question-Answering concerns building systems that “automatically answer questions posed by humans in a natural language”. The real examples of Question-Answering applications are: Siri, OK Google, chat boxes and virtual assistants.

5. Automatic Summarization

Automatic Summarization is the process of creating a short, accurate, and fluent summary of a longer text document. The most important advantage of using a summary is it reduces the time taken to read a piece of text. Here are some applications – Aylien Text Analysis, MeaningCloud Summarization, ML Analyzer, Summarize Text and Text Summary.

Data Science Machine Learning Certification

6. Chatbots

Chatbots currently operate on several channels like the Internet, web applications and messaging platforms. “Businesses today are interested in developing bots that can not only understand a person but also communicate with him at one level”.

While such applications celebrate the use of NLP in modern computing, there are some glitches that arise in systems that cannot be ignored. “The very nature of human natural language makes some NLP tasks difficult…For example, the task of automatically detecting sarcasm, irony, and implications in texts has not yet been effectively solved. NLP technologies still struggle with the complexities inherent in elements of speech such as similes and metaphors.”

How Pharma Companies Are Using Machine Learning and AI to Fight Against COVID-19

In the midst of a crisis as big as COVID-19 which has as per the current update taken more than 80,000 lives around the world and caused nations to go under a lockdown, machine learning and artificial intelligence has played a vital role in detecting COVID-19 positive cases and helping fast track the tests and analysis of drugs that can be a solution to the problem.

Countries around the world are building algorithms to better understand the molecular structure of the diseaseso that the so-called protein around the SARS-CoV-2, the virus that causes COVID-19, can be blocked.

Use of AI and machine learning around the world

The legendary story of a Canada-based AI named Bluedot is not something one can forget. Buledot is a low cost AI based tool that predicted the outbreak of the disease in December 2019 and also predicted the top 20 destinations where passengers from Wuhan, the origin of pandemic, would arrive.

Deargen a South-Korean company built an AI tool named MT-DTI to test and analyze the molecular bond of the SARS-CoV-2 protein and recommend medication on the basis of the same. Even though their recommendations are yet to be reviewed and tested properly, their find might prove to be a super solution to reduce the number of death counts and covid positive cases.

Insilico Medicine, a Hong-Kong based company instead of building a platform to recommend the currently available medication to break the protein of covid-19 virus and stop it from replicating, built an AI based tool to formulate and test the potency of new and chemically advanced medication to break the chain.

Benevolent AI, a British startup based on its machine learning tool discovered six important covid-19 virus fighting compounds that can prove to be helpful in curing and limiting the spread of the disease. Out of the six compounds discovered, ‘baricitinib’, a compound used to cure rheumatoid arthritis according to the sources, proves to be the safest compound that can be tested on the covid positive volunteers.

Use of AI and machine learning in India

The spread of the covid-19 pandemic in India began by the end of January 2020 and till date more than 5000 cases have been reported. The Government of India declared a lockdown by mid-March 2020 and in the middle of all this when misinformation and rumors were rising day by day, to tackle the problem the Government of India launched its covid-19 tracking app called Aarogya Setu that means ‘a bridge of health’.

This AI-based app uses bluetooth and the mobile location of the user and informs them if there is any person covid positive within 6 feet of their location or not. The app checks the user’s data in their own database and in case the data matches a corona positive patient then it only notifies their presence keeping their identity anonymous.

India has also launched a whatsapp chatbot and any one using the whatsapp platform can access the chatbot by simply typing “MyGov Corona Helpdesk” and get the relevant and authentic information relating to the symptoms and how they can get help from direct sources.

Apart from the above initiatives to tackle the pandemic, medical practitioners, data analysts and data scientists from around the world are trying to find ways and means and analyzing the database to capture the trends and are working day and night to find best possible cure to fight the disease.

AI’s Fight Against Coronavirus Continues

Posted on by Dexlab

AI’s Fight Against Coronavirus Continues

The world has come to a grinding halt with the spread of the deadly novel coronavirus (COVID-19), one of the most contagious diseases to affect us as a people of late.

In little over three months since the virus was first detected in China’s Wuhan late last year, it has spread to more than 90 countries, infected almost a million people, and taken about48,000 lives as of Thursday, April 2, 2020.

Scientists, governments and health organizations are doing the best they can to contain and fight the disease and they are trying to take all the help they can. Including the help of technology – and Artificial Intelligence – in tracking, diagnosing cases, disinfecting areas and speeding up the hunt for a cure.

Here is a short essay on how artificial intelligence is assisting in the fight against COVID-19.“Data science and machine learning might be two of the most effective weapons we have in the fight against the coronavirus outbreak,” says a report.

Tracking the virus outbreak with machine learning

In December last year, a Canada-based artificial intelligence platform that tracks the spread of infectious diseases around the world, detected a cluster of “unusual pneumonia” cases reported in China’s Wuhan. You can read about the detection of the disease here.

The Toronto-based start-up uses Natural Language Processing or NLP and machine learning algorithms to scour tons of information on infectious diseases from sources like statements from health organizations, commercial flights and live stock health reports. It alerted its clients about the outbreak of the disease almost a week before international health organizations declared the outbreak of COVID-19 in China.

Computer Vision being used to detect coronavirus infection

As of today, authorities the world over are checking temperatures of their citizens at airports and railway stations or other crowded places through thermal guns and manually screening them for signs of fever, cough and breathing difficulties.

However, computer vision algorithms can accelerate this crucial screening process by equipping cameras with computer vision technology.

In China, a tech giant has invented a thermal scanner that uses computer vision and infrared sensors to check people’s temperatures in public places. The system invented can check up to 200 people per minute.

Another tech giant has invented a system that uses AI to detect coronavirus in chest CT scans (in 20 seconds as opposed to the 15 minutes spent by human health workers) with a 96 per cent accuracy rate. The system is reportedly being adopted by 100 hospitals in China.

Data Science Machine Learning Certification

AI is speeding up drug research

Developing new drugs and vaccines, in the race to win the fight against coronavirus, is proving long and tedious. Some reports suggest it can take anywhere near 12 years at a cost of billions of dollars.

However, that said, AI will help speed up the process of drug discovery to some extent. “DeepMind, the AI research lab acquired by Google in 2014, recently declared that it has used deep learning to find new information about the structure of proteins associated with COVID-19”, a process that could have taken many more months.

“Understanding protein structures can provide important clues to the coronavirus vaccine formula. DeepMind is one of several organizations engaged in the race to unlock the coronavirus vaccine. It has leveraged the result of decades of machine learning progress as well as research on protein folding.”

5 Problems Machine Learning Can Solve

Posted on by Dexlab

5 Problems Machine Learning Can Solve

Machine Learning, a subset of Artificial Intelligence, has taken the world by storm. A method of data analysis, it is a system that is equipped with expertise to learn from data, identify patterns and take decisions with minimal human intervention.

From clearing our email inboxes of spam to tagging our friends’ faces in social media photograph uploads, Machine Learning is crucial to all aspects of our lives. Here are some problems that Machine Learning can easily take care of.

Manual Data Entry

The problem of inaccuracy and duplication of data that business houses wish to avoid when automating their processes can be tackled with the help of Machine Learning (ML). A report says, “ML programs use the discovered data to improve the process as more calculations are made. Thus machines can learn to perform time-intensive documentation and data entry tasks.”

Moreover, ML knowledge workers can, nowadays spend more time solving problems of higher-value while ML takes care of repetitive work. “Arria, an AI based firm has developed a natural language processing technology which scans texts and determines the relationship between concepts to write reports.”

Detecting Spam

Spam detection, one of the earliest tasks for ML systems, has upgraded.“Four years ago, email service providers used pre-existing rule-based techniques to remove spam. But now the spam filters create new rules themselves using ML.”This is because of ‘neural networks’ installed in spam filters, “Google now boasts of 0.1 percent of spam rate.”

Neural Networks fitted in spam filters can teach themselves to learn to recognize junk mail and phishing messages “by analyzing rules across an enormous collection of computers. In addition to spam detection, social media websites are using ML as a way to identify and filter abuse.”

Product Recommendation

Unsupervised learning enables companies to put in place a product based recommendation system. By studying purchase history of a customer and a correspondingly large inventory of products, ML models can identify certain products in which a customer is likely to be interested.

“The algorithm identifies hidden pattern among items and focuses on grouping similar products into clusters. A model of this decision process would allow a program to make recommendations to a customer and motivate product purchases.”

Medical Diagnosis

Machine Learning in the medical field is touted to improve patients’ health with minimum costs. “Use cases of ML are making near perfect diagnoses, recommend best medicines, predict readmissions and identify high-risk patients. These predictions are based on the dataset of anonymized patient records and symptoms exhibited by a patient.”

Data Science Machine Learning Certification

Computer Vision

Computer vision “produces numerical or symbolic information from images and high-dimensional data. It involves machine learning, data mining, database knowledge discovery and pattern recognition.” Potential business applications of image recognition technology can be found in healthcare and automobiles. A tech giant has produced a computer vision powered earpiece that can narrate its interpretation of the outside world to a visually impaired person.

Machine Learning has many applications in industries the world over. For more on this, or a related subject, do peruse the DexLab Analytics website. DexLab Analytics is the best Machine Learning course in Delhi.
