TABLEAU is considered as a Business Intelligence tool to visually analyze data and is used by businesses, academic researchers, and many government organizations. With the tool, users can create and distribute an interactive and shareable dashboard, which depict the trends, variations, and density of the data in the form of graphs and charts. The software allows data blending and real-time collaboration. The unique features of the tool include:
✔ Tableau's drag and drop interface to visualize any data, explore different views, and even combine multiple databases easily
✔ as it does not require high level of programming expertise, any user with access to data can use the tool to derive value from the data
✔ visual tools like colors, trend lines, charts, and graphs to visualize and analyze data for potential correlation between different data points
✔ allows blending different relational, semi-structured and raw data sources in real time

Explored the tool and tried to analyze data from KDD cup 2015
KDD Cup is an annual Data Mining and Knowledge Discovery competition organized by ACM Special Interest Group on Knowledge Discovery and Data Mining, the leading professional organization of data miners. In 2015, the task was to perform Dropout Prediction on XuetangX, one of the largest MOOC platforms in China. The dataset had 39 courses, 120,542 enrollments and 79,186 users. The Tableau tool was used to perform descriptive analysis of the KDD cup 2015 data.

AUDACITY is a free, open-source and easy-to-use, multi-track audio editor and recorder software. It has cross-platform compatibility and supports multiple plugins and libraries for enhanced functionality. The important features of Audacity include live recording of sound and audio playback on a PC, editing multiple audio formats such as MP2, MP3, AIFF, WAV, FLAC, taking different sound documents and duplicate, cut, blend, or graft them together and change the pitch or speed of a sound recording.
SCRATCH is a unique visual programming language that allows users especially students to create their own interactive stories, games and animations. Designing Scratch projects enable students to think creatively, reason systematically, and work collaboratively. There are four main elements of Scratch:
- stage, where the output of the program is displayed
- sprites are the main characters or actors used in the programme
- script is used to programme each sprite. It tells the actors what to do
- programming palette which is used to programme the sprite to perform some task

Sunny Prakash Prajapati, Shirish, Utkarsh, Arjun Prasad
As part of exploration of the tool, the Scratch programme was used to develop a race game.
Instructions:
Click on the green flag
Press space bar continuously to see the race game
ORANGE
Orange is an open-source, code-free, GUI based platform that is commonly used for data mining and analysis. It helps in getting a understanding of the data at hand and also helps to quickly build machine learning models to understand the relationship between the data points better. The platform is built on Python that lets you do everything required to build machine learning models without code. Orange also includes a wide range of data visualisation, exploration, preprocessing and modelling techniques.

A built-in dataset named Iris flower dataset was used to make predictions. The dataset contains 150 instances, 4 features and 3 class labels (Iris setosa, Iris virginica and Iris versicolor).
Step 1: Load the data
Step 2: Divide the data for training and testing purpose using Data sampler widget (use 75% as training data; remaining 25% as testing data). Out of 150 data, 113 are used for training purpose.
Step 3: To create the machine learning model, the Tree algorithm was used.
Step 4: To make predictions, choose Prediction tab and connect with Data sampler widget. Make connection between Remaining data and Data so that the testing data will be used for making predictions.
Step 5: Connect the trained model as another input for the Predictions. Clicking on the Predictions widget displays the actual output and predicted output.
Step 6: Add the Confusion matrix widget to clearly identify the correctly predicted and incorrectly predicted samples.
Step 7: Add a Data table widget to display the correctly and incorrectly predicted data.
Step 8: Scatter plot widget can also be used to visualize the predicted values
BRAINSTORMING TECHNIQUES
Brainstorming is considered as a unique method to generate creative ideas for problems. The process involves sharing of ideas without any judgement. The process involves thinking freely from diverse perspectives, encouraging critical thinking and teamwork. For every specific problem identified, it is important to focus on the point of view statement, which make the problem statement human centred, considering the specific users and their needs. The following are some of the online brainstorming tools:
1. IdeaBoardz
2. Google Documents/Sheets
3. Coggle
4. WiseMapping
5. Freeplane
6. MindMup
7. Mindomo
8. Mind Vector
9. Mindly

Broad problem identified: Commuting during rainy season
Specific problem identified: Unpredictable rains in Mumbai so there is always a fear of getting wet, infections and wetting of mobile phone, laptop, getting late etc.
Point of View statement: Hari is new at the IIT Bombay campus and due to the unpredictable rains, he forgets to carry an umbrella or raincoat every time. He gets wet in rains and is frequently facing many health issues.
Tinkercad
Tinkercad
Tinkercad is a free online platform with a wide collection of software tools that enable beginners to create 3D models. The tool is based on constructive solid geometry (CSG), which allows users to create complex models by combining simpler objects together. Hence, the tool can be used by children, teachers, designers to create models. The output models created are also compatible with 3D printing.

HTML5 Package
HTML5 Package
HTML5 Package or H5P is an open-source interactive tool that allows to create, share and reuse interactive HTML5 content. Interactive videos, interactive presentations, quizzes, interactive timelines can be developed using the tool to hold the viewer’s attention. H5P is coded in HTML but does not require the user to have definite knowledge of the coding language. The backend interface lets the user to drag and drop elements or directly add interactive buttons to the video. The following are the important steps to create an interactive video:
Identify the suitable video
Identify the reflection points to add interactions
MCQs, True or False questions, Fill in the blanks, feedback questions drag & drop can be added
The interactive video can be shared using the embed option to share the video on Moodle or personal web page.
FDM 3D machine
Fused deposition modeling (FDM) is a material extrusion method of additive manufacturing where materials are extruded through a nozzle and joined together to create 3D objects. The “standard” FDM process distinguishes itself from other material extrusion techniques, such as concrete and food 3D printing, by using thermoplastics as feedstock materials, usually in the forms of filaments or pellets. A typical FDM 3D printer takes a polymer-based filament and forces it through a heated nozzle, which melts the material and deposits it in 2D layers on the build platform. While still warm, these layers fuse with each other to eventually create a three-dimensional part. FDM printers dominate the 3D printing market.
Itouch Plus Pen are 3D pens used to create outlines for the objects that you need to 3D print. Once the 3D objects get created, they could have some voids, flaws or deformities on their outer surface. You can use this 3D pens to fill the voids of the 3D objects and offer them a better outer finish. Different colors of PLA filaments are used as the glue. It is easy to operate and safe to use. The filament is heated, squeezed and cooled by the pen body. Using the pen, it is able to create custom 3D objects without clogging and smooth graffiti. The filament type can be freely switched and the patented nozzle and thermal design prevent burns. It automatically shuts down after 5 minutes of inactivity. The pen can be used by children to improve their spatial thinking skills and encourage their creative imagination, thereby creating quality time.
