The problem Age & Sex Detection, Tool of Solidity & Blockchain solves

Age and Sex Detection can be used in many real-life applications such as for criminal identification and investigation which limits the search for wanted criminals. It can also be used in marketing and analytics for example, if we have a mall and we want to analyse what age group and gender are attracted by which section and brand, where it can be used and help to improvise the business. It can be used to cross-check the details and restrict a certain age from using particular services such as tinder.
As a Beginner in Blockchain Technology, I was not getting many resources from which I can learn solidity and about blockchain and create Dapps, Once I move forward, I collected all the resources I have gone through and did a comparison between the tools you will need and I have also created a curated path and steps we have to take in order to build a Dapps or blockchain project. This will not only save time and search but we can also get started with it.

Challenges I ran into

As I have to build and compare between three models and pick the one which is fast ad efficient, In order to achieve I was not able to think of any algorithms for the third one and not able to increase the efficiency by more than 97%, It was challenging as I increase the time for training and epochs, estimation of such factors was difficult for me to judge and bring down the desired result.
The main challenge I face in Solidity is to write a crisp and to-the-point comparison as there were many things to write and learn from the topics, but as a beginner, we always want to try out first, in order to observe the technology, So to make it interesting I have made it short and to the point.
