Can Artificial Intelligence identify "Taste?

There is lot of debate these days about Artificial Intelligence (A.I). A large scientific community expects that in coming year’s lot of the problems that are bothering humankind can be solved with help of A.I. Let us discuss whether Artificial Intelligence identifies "Taste" such sweet , bitter , sour etc.,. For building a “taste identification system” we will need computer aided “Taste Buds”. These artificial taste buds will require some kind hardware instrumentation that can get stimuli from the food item such as lemon and give response.


The artificial taste buds should in fact first be able to identify “Food Items “, from where it can get idea about the taste. For recognition of the food items such as fruits, vegetables an image processing based system can build and from its database, the taste signature can by just be displayed characteristics of the Food and taste is one the characteristic of a food. However, this is does not qualify a sophisticated artificial Intelligence system.

The next will be a taste identification system that recognizes food taste using physical and chemical properties of the food items. In such case, a system has to work in manner that either it can recognize its biochemical properties at molecular level or at the level; it can characterize the food substance properties such as taste. This depends up the level of instrumentation we have. If we have instruments that can seek information at molecular level from a substance than the database of “tastes” can be maintained with help of molecular level.


Yes , AI can find your Taste :Taste Identification System (Molecular level)

If, we do not have facility to work at molecular level then we can build a system that extracts the properties of the food item-using array of sensors. These array of sensors can simply build a wave spectrum of the food item and display corresponding taste value if it has some trained machine learning model. A simplified process can be understood from the diagram below :

I hope , by this time it is clear that machine learning modeling , deep learning modeling can help us build “taste machines “.

Data Interpretation : Understanding OLS Regression Results and Outcomes

Data Interpretation Understanding OLS Regression Results & Outcomes Puneet Arora  These days Regression as a statistical method is undervalued and many are unable to find time under the clutter of machine & deep learning algorithms. But, everyone knows that “ Regression “ is the base on which the Artificial Intelligence is built on. In this article, we will learn to interpret the result os OLS regression method. In this method, the OLS method helps to find relationships between the various interacting variables. The mathematical relationship is found by minimizing the sum of squares between the actual/observed values and predicted values.  But before, we can do an analysis of the data, the data needs to be collected. There are primarily two ways by which we can obtain data for regression: Primary source and Secondary source. In the primary source, we directly collect data from the source (Original) for example by getting some survey form filled and in

Vedic Plaster (FAQ)

In this article, I shall try to address the most frequently asked questions (FAQ)  on “ Vedic Plaster ”, a  product manufactured and sold by Dr Shiv Dharshan Malik . I got introduced to product “ Vedic Plaster ” some two years ago when I saw it’s the application at Bhopal, Sehatvan. I recently also made a trip to his Dr Shiv Dharshan Malik’s place Rohtak . Hence, based on my knowledge, experience and feedback from others I will try to remove confusion from the minds of people about it. Vedic Plaster Office  What is Vedic Plaster? It is a mixture of cow dung, mud, lime and other ingredients that inhibit the growth of bacteria/fungi. The purpose of this mixture is to act as a wall plaster, not necessarily as mortar mixture. Can Vedic plaster be used for Bathroom floor and wall?  Yes, it can be used for the walls of the bathroom but, it will not be prefered as a bathroom floor plaster.  This plaster can provide a smooth surface and it can handle water in the lon

Overcoming Barriers to Roof Top Raise Bed Gardening

                            One of the biggest barriers to Roof Top Gardening is “Weight”. .Yes, I'm not talking about your Weight … Many people get discouraged by the fact the weight of the Pots and Potting mixture. As it normally so  high that it is hard to carry and construct Raise Beds on rooftops or in upper floors of the building. In-fact , I have been feeling the same challenge , that is why I had to resorted to Plastic Buckets and Containers. It's okay to use Plastic for growing your own food. But , alternatives to plastic must also be considered and put into practice. Move  over , we should think about overcoming the limitations of growing plastic buckets. A  raised bed with  potting mixture is better for growing veggies as compared to the plastic containers. This is because a raised bed would store more volume of soil  and will have a better mico-ecosystem as compared to the ecosystem of plastic containers. They allow us to have better drainage and the

Gobar Brick , Cow Dung and Tiles

Houses that  are heat resistant both in winter and Summer are rare these days. As we grow the socio-economic  ladder  , we want to live in a pucca  house made of cement. In-fact , We want every thing "Permanent ", "Ever Lasting"  things in life. Forgetting that  Every thing in this world is transient. We want to make a pucca house that the next generation does not like and they want to change the design of house , buy new furniture , buy new bed sheets curtains and in-fact the new generation keep coming back  and ask was  change in house itself. Some even go beyond  They want to move to new better places not just for jobs but for better life. Yet ,we want to make a pucca houses . A house that lasts generations.. Mobility is key factor in remaining employable these days. You find thousands of houses vacant just because the residents have moved away to make better living. Yet we want have house that lasts for ever. We never buy a Car , we the thought that it w
