The problem Divide n conquer solves

problem

• While dealing with real-life data science problems the Datasets can be very huge.
• In cases like that, the system you are currently working on might not have enough resources to contain the whole data set psychically at a time.
• If you've done some projects on deep learning you understand that we train the model with small amounts of data at a time, to improve processing speed and fine-tune the parameters in between. we call it a batch.

Solution 💡

Dividing the Dataset into batches of smaller size

how we do 😎

• We upload the dataset by splitting the entire dataset into parts
• when user clicks receive, one batch is sent at a time
• only after the first batch is completed the next batch is fetched
• during the process of fetching, the first batch is deleted in order to free the space

Use case 👨‍💻

Consider another scenario where you are applying a Deep Learning Model on a huge image dataset and you don't have enough memory to store the entire dataset, this problem can also be solved by using Divide And Conquer. The dataset can be divided into smaller chunks and stored in the blockchain and can be used to train the model by downloading and deleting different parts of the dataset

How to Use 🤔

• Install the module
• run

  dividenconquer.upload()

  to upload the dataset into web3.storage
• after uploading, click on the

  dividenconquer.download_first()

  to download the first batch of the dataset
• for the subsequent batches you can run

  dividenconquer.download_next()

• NOTE : these functions have to be called within the Jupiter notebook while writing the ML model

Challenges we ran into

Challenges we ran into

Synchronous download of batches

The main problem was the synchronous download of the data batch by batch, if the data was fetched after the previous one is completed, then the entire code would have some amount of empty time between batch 1 and batch2

• to avoid this, we have started downloading half batch at a time thereby leaving the remaining half as a buffer either for the incoming next batch or the about-to-be-deleted batch
  

Velo by wix

It was interesting to work with wix , but also time consuming since this was our first time with the platform,we were unable to handle few customizations for our website

incremental learning

Different problems include finding a proper classification algorithm that can perform incremental learning and also exploring Wix to create a website which proved to be pretty useful in the end

• We found that SGDClassifier can be used for incremental learning

ipfs in python

we were unable to execute the store function in python , since the documentation only had js

• created a js file that runs through the trigger made by the

  main.py
