Garbage In is Garbage Out in Data Sciences!

Whether you are a data analyst in a firm or a developer training its machine learning model, you deal with data. Rather you need data! Data is one of the essential things which is needed to create a foundation. The decisions and results are relied on the output you get from the data. Thus, data is important and like every other thing, it also works on the principle of Garbage In, Garbage Out.

Many people make mistake while feeding data to their data set with a hope to get better results.

However, they end up having an ugly dataset with a greater risk of damaging their product.

The 6 most common mistakes are: Not Enough Data, Low Quality Classes, Low Quality Data, Unbalanced Classes, Unbalanced Data, No Validation or Testing.

These mistakes can be fixed which could further help in fetching good results.

One just need to remember that their dataset is equally important to the model they are working on. Without a balanced dataset, getting a fine finish product is next to impossible.

Artificial Intelligence: A boon or a bane for employment

Destroying traditional jobs but creating new ones, technical innovations have changed the course of work over the years. The Industrial Revolution of the 18th century marked the transition to new manufacturing processes, effectively increasing the output levels and discovering the modern industrial marvels. With AI improving the standard of living, the current and future generations are likely to witness taxing employment pattern changes.

AI would change the future of work by bringing about the following changes:

1)      Create new jobs: Tasks requiring the least of the human cognitive mind would be dealt with the application of modern AI powered robotics allowing individuals to devote their time to community services, volunteering etc.

2)      Bring Automation: A research carried out by Carl Benedikt Frey and Michael Osborne of Oxford University in 2013 reported that approximately 47% of jobs would be automated in the next few decades with non-routine jobs and tasks requiring  high cognitive and good social skills having the lowest probability of being automated compared to a greater probability involved in automation of manual jobs and routine jobs like data entry, production logistics etc.

3)      Increase the gap between the owner and the worker: AI is likely to widen the gap between high skilled and low skilled workers and also increase the persistent inequality between the owner and the workers by laying off workers that would inflate the profit margin of the owners as robots and chat-bots would not demand overtime allowances.

Gartner, the global research and advisory firm, reported that AI is creating more jobs than it is destroying by bringing about a net increase of nearly 2 million jobs by 2025. The core objective of AI should be to make human workers more efficient without laying them off. AI coupled with human intelligence is all set to revolutionize the economy we inhabit.

Life saving Artificial intelligence

Artificial Intelligence, big data and machine learning have been ruling the industry in recent times. Starting from Amazon to Google, indulgence in predictive modelling is indispensible. When it comes to the human body, well, artificial intelligence plays a pivotal role in saving lives. Rampant use of AI is involved in CT scans in cases of stroke or brain injuries. Radiologists have a backlog of cases which might delay the detection of the criticality involved in a particular case. To the rescue comes AI, which by streamlining the CT scan interpretation workflow by triage process and automation of the initial screening process, radically reduces the time lapse in detection and diagnosis of time sensitive cases. To detect abnormalities demanding urgent attention such as intracranial haemorrhage, cranial fractures, midline shifts etc, has provided automated deep learning algorithms to assist physicians. The algorithms’ accuracy is equal to that of a physician and classification algorithms are used in radiology itself. TITAN X of NVIDIA, cuDNN and GeForce GTX 1080 GPUs were used that achieved almost 95% accuracy rate as compared to that of 97% by radiologists. Such AI algorithms tend to become a life saver in a world where there is an acute shortage of specialized radiologists.

Analytics in Construction Business: Scope and uses.

Business Intelligence and Business Analytics are being used interchangeably nowadays in almost every field of businesses worldwide involving, in particular, leveraging the data of a company in order to evolve and grow. In addition to other sectors, predictive analytics greatly benefit the construction business categorizing information with relevance and accuracy. Predictive Analytics assists in the following ways:

1)      Leveraging work packages: Predictive Analytics helps in task breakdown matching the right people for the right job, scans past project documents, including the Work Breakdown Structure (WBS), and assess the fallacies in project execution. With such technical know-how, businesses can scientifically cut on resourcing costs without compromising on potential.

2)      Prescribe, Predict and Describe: Descriptive Analytics creates a database containing the failures and their severity which is followed by predictive analytics analyzing their recurrence. Finally, prescriptive analytics explores options that can prevent such fallacies in future work.

3)      Scanning risks: The construction space advocates vociferously for the health and safety of the crew and this purpose could be served by predictive analysis in conjunction with prescriptive analytics. Pinpointing disaster zones to nth degree accuracy and using pedometer analytics to measure the distance the crew covers, predictive analysis places heavy-duty equipments at various access points improving visibility in low lying areas and also alerts about the resources that demand servicing. It ensures both the project’s progress and the business’s adherence to the crew’s safety standards.

4)      Lowered production costs: Manual monitoring methods are laborious and entail a cost on the business’s profits. GE’s Kimberlite Survey reported that businesses using predictive approach using retrofit sensors and cloud computing experienced approximately 40% less unplanned downtime.

5)      Immersive Insight: Predictive analysis converts dormant data into actionable analysis and prevents any information from lying unanalyzed.

Big Data Analytics in the Indian Economy

Data has become a central part of the economy and applications in analytics have been proliferating fast from private to the public sector. Data collection and analysis are at the root of critical economic decision-making which makes the socio-economic issues easy to interpret and comprehend, thus playing a pivotal role in economic battles. Big data analytics help the government in infusing transparency into the system, combat fraudulence and deliver public services effectively and efficiently.

The year 2017 will always be known to have triggered off this big data journey with Demonetization and GST being the two notable data-driven policies injected into the system coupled with the shift in focus to the macroeconomic issues like Aadhar data collection which gained an edge to bring economic reforms. Using big data analytics, the following few untapped areas can positively impact the government:

1)      Tax and Welfare: The ‘Project Insight’ rolled out by the Indian govt. used data mining techniques to counter tax evasion in 2017. It also helped in tracking down deregistered firms and gathered information about black money potholes in existence.

2)      National Security:  The uncertainties faced by national security officers with regards to the unpredictable security situation can be overcome by the use of analytics thus enabling them to combat crime attacks easily.

3)      Healthcare: Healthcare system in India has the opportunity to leverage big data analytics on the data emanating from biometric, patient records and thus provide actionable insights with greater prediction power contributing to effective public health.

4)      Education:  Ranking second in terms of student enrollment,  the titanic amount of student data can be analyzed to predict statistical figures and would help in efficient budget allocation.

In addition to these, analytics has also entered the farming sector where the concept of geo-tagging the entire agriculture infrastructure was implemented. Although the entire process is still in its infancy, the outcomes that big data analytics present to the Indian economy are much more effective. Though big data analytics have not been used in policymaking yet, the budget allocation hints at a widespread adoption of artificial intelligence and big data analytics in the Indian economy.

Growth stalled? What to do next

For any budding company or an industry, the ultimate driving force that can help them survive the thorny path of competition is ‘growth’. A particular company may not last long without growth fuelling its fire of success. It not only ensures easy and faster cash transaction but also makes ways for new project, satisfied customers and talented new hires. However if growth halts once, a company’s future is fully dependent on its founder’s ability to restart the engine of success. In fact in many cases half of the new businesses close down in five years in absence of the driving force.  Question arises on how to take up a company from the path of despair and jumpstart growth again. Let’s look at the following tips:

·         Adding empathy screening to hiring process- A better understanding among the workers of the company can lead to better anticipation of needs and improving productivity thus inevitably leading to faster growth processes. In fact empathetic behaviour helps to evaluate others’ agendas and deliver something that meets the needs of all.

·         Investing in relationship not in sales- Where authenticity is craved by the modern customers, one should promote content in such a manner such that it leads people to have a deeper connection to the brand. Just a mere commercialisation with clever camera edited marketing skills won’t help accelerate growth of the products much if it doesn’t make any sense for the brand.

Hence putting together a strong team and leveraging the most attractive features of a company can put off the stagnating growth and initialise the processes of success again.

China’s Laser Blaster

Signs of exhilaration are heightened among the ‘Star Wars’ fans as China has invented a new weapon called ZKZM-500 similar to the laser blaster in the movie. Weighing more than 6.6 lbs., the 15 mm laser gun can fire more than 1,000 laser shots, each one lasting up to 2 seconds. Although the weapon is claimed to be non lethal by the Chinese government, the invisible energy beam produced by it can cause instant carbonization of human tissues and skin. Infact it has the ability to penetrate through windowhs thus igniting gas tanks and burning anything nearby. However burning hole through a body will take several zaps by the weapon. The gun can have wide usage such as it can be used by the Government to fire illegal banners in a protest or setting fire to the clothing of the protester. Although ready for mass production, its creator ZKZM Laser hasn’t yet found a licensed company ready to take up the $15,000/unit worth guns. The weapons will be in future handed over to the Chinese army and police.

Big Data in Aviation Industry

Fifteen years ago it was only fair for the airlines companies to keep record of the ingoing and outgoing flights only. But now let’s imagine a sudden storm hitting the East Coast today. This would imply that several flights will be delayed. Hence keeping up to their standards and adding a value to the every penny the passengers have paid would involve several entailing jobs like determining the flights to be connected with the airline, baggage transfer time, the number of transferring passengers, the flights that are coming from and so on. It naturally means a proliferating amount of big data sifting and shifting from a constellation of different sources. A Boeing 787 alone creates a half a terabyte of data every day. Big data in aviation are useful in many cases such as:

·         Fuel Efficiency- Fuel is the second highest expense for airlines and estimating power has developed to a point where airlines can congregate and process the enormous amounts of data they need to analyze on a per-trip basis. It is hoped that data mining will produce actionable intelligence around decisions such as adding or subtracting flights to routes, setting fuel loads for each aircraft, and selling additional passenger tickets. 

·         Smart Maintenance- The big data, including mechanic write-ups, shop findings and in-flight measurements, helps the airline company to plan equipment maintenance with minimal disturbance to flights.

·         Airline Safety- A data collection and analysis program named Data4Safety has been recently launched by The European Aviation Safety Agency (EASA)  to detect risks using a amalgamation of safety reports, in-flight telemetry data, air traffic surveillance information, weather data and so on.

On demand start-ups: failure or success? On demand start-ups: failure or success?

Technology has helped develop such apps which provides services at the door right from cabs to groceries. Provision of other services like plumber, electrician and other maintenance services still are unavailable on apps. Providing these services is not a good option because if we see the calculation then the overall costs is more than the money paid by the customer. To break-even the customer should use their services at least 10 times to average the price to 44 Rupees. There are other factors too like loyalty of customers and discounts which is definitely not sustainable for the company. This market is unorganised sector in India and has a lot opportunities. Customers complained about quality of services and prices and hence this needs to be rectified.
