MachineHack has not too long ago concluded Information Engineering Championship – a hiring hackathon for information scientists and information engineers, organised in affiliation with Publicis Sapient, iMerit, USEReady, Tiger Analytics & The Math Firm.
The hackathon was part of the Information Engineering Summit 2022, introduced by Google Cloud and organised by Analytics India Journal, and was an enormous success with over 700 registrations. The winners stood an opportunity to current their answer method at DES 2022 & acquired a chance to land an interview with one of many main analytics organisations.

Listed below are the answer approaches of the winners who secured the highest three positions within the Information Engineering Championship.
Rank 01: Sylas John Rathinaraj
Rathinaraj acquired all in favour of predictive analytics in 2017. He attended Coursera and Udemy programs in statistics, exploratory information evaluation (EDA), machine studying, information science and deep studying to enhance his expertise. As well as, he has participated in a slew of ML hackathons on totally different platforms to check and construct his information.
Method
The members had been offered particulars about an airport together with a climate info dataset. That they had columns comparable to ‘DATE’,’ LOW’,’ HIGH’, and’ TIMESTAMP’ for which the members might impute the fixed worth. Within the yr column lacking data, you’ll be able to impute 2020 as they’d 2020 as a yr for all different data. It’s the similar with the month column the place one can impute with 01 as we had 01(Jan) for all different data. The principle challenges within the datasets had been:
- Information missingness
- Formulation column with uncertainty
Information missingness
Within the airport particulars with the climate info dataset, for a number of columns, 20 per cent of the information are lacking. The bar chart under reveals the non-missing data rely of the columns.
The system for computing might be simply formulated with different dependent columns. For lacking data within the dependent columns, used imputation primarily based on group-by of the imply worth.
Formulation column with uncertainty
The definition for the WIND_CHILL column given within the competitors was “the perceived temperature as a result of cooling impact of wind blowing”. Rathinaraj utilised info from the TMAX (temperature max0, AWND (MAX wind pace of the day), SNOW and timing of the day when the flight departs. He used a mixture of this info and calculated the WIND_CHILL columns. WIND_CHILL column is in ranges from 0 to 80 Fahrenheit. The WIND_CHILL column is important within the competitors to get the most effective rating because the imply absolute error will increase in the identical vary(0 to 80) for incorrect calculation.
Rathinaraj feels that MachineHack supplies members with totally different domains of the ML and Information Engineering competitors. “Taking part within the competitors helps me to develop into extra educated. After the competitors ends, I all the time spend time exploring the top-ranked achiever’s answer method and codes,” he provides.

Rank 02: Jeena Binex
Jeena has been working as an embedded system engineer for 9 years in Mumbai, and for the final 5 years, she has been working in a courier firm in Singapore, the place her profile is to keep up the In-house ERP system which is constructed on .Internet Framework and SQL Database and analyse the information out there to establish the traits for gross sales, operations, customer support and many others.
“I began analysing the information with the restricted information I had, and my curiosity in information analysing began right here and therefore determined to have in-depth information on this area. So, in July 2021, I enrolled in an information science on-line course. After spending 12 months within the course, I studied supervised and unsupervised Machine studying and Time Sequence. Then, I moved on to deep studying, NLP.
Method
Jeena’s method to the issue included the next steps:
- Studying by way of the dataset and understanding the which means of every column of the dataset (26 columns)
- Studying by way of the options to be created and figuring out the columns of the dataset contributing to the creation of options. The principle agenda was to fill the lacking values of those columns,
- She used two approaches for filling the lacking values-Regressive imputation and Imply and median imputation.
- Lastly, she calculated the options utilizing the formulation.
“Fixing hackathons helped put into follow the information I gained from the idea, which was an enormous confidence booster for me,” concluded Jeena.

Rank 03: Suresh Arunachalam
Suresh has all the time been captivated with information science and interested by understanding its reference to real-world enterprise use instances. “This curiosity enabled me to spend extra effort through the day and the weekends to be taught extra about it from the web, which finally created a pathway to realizing concerning the hackathon occasions taking place throughout the globe within the information science house,” he mentioned.
Method
Suresh says {that a} use case was given to calculate Wind Chillness, Airline Seat Distribution, Snow Ratio and some different helpful items of data together with the date and time stamp, which helps the airline corporations to plan their journeys from the airport information dump. The dump contained about 200k rows and 26 columns with varied info (comparable to wind pace, latitude, longitude, snowfall, flight ID, and many others.).
He adopted these steps:
- At first, he eliminated the undesirable columns and changed the null values utilizing Max () and Median () strategies from NumPy.
- He did a column break up to kind the date and timestamp utilizing Pandas.
- He then carried out some primary arithmetic operations to calculate the anticipated use case outcomes.
“I used to be delighted to be a part of this hackathon occasion performed by MachineHack, which helped me to enhance my analytical and problem-solving expertise. Furthermore, the principles and pointers set by MachineHack for such occasions helped in intuiting my aggressive expertise to maintain myself within the high three positions every single day on the leaderboard,” Suresh provides.
