Machine Learning datasets for Innovation and Progress

1. Machine Learning datasets for Innovation and Progress

2. ”It is widely known that machine learning is as good as the data that we input in it. We often use an extremely large dataset to teach the machine learning model to differentiate between the identified datapoints.” • Before we go through training data, it is worth mentioning that in machine learning, there are three types of machine learning datasets: training, test, and validation. • If further classified, there are 2 different types of training data: Labeled data and unlabelled data.

3. Labeled data • Is used for supervised machine learning models. The data is tagged, labeled, or annotated by humans according to the defined criteria so that the particular machine learning model can produce the desired output. • Labeled data also can even have more than one label depending on the set criteria. • For example, an image of a "drink can" could be assigned more than one tag; can, crushed can, drink can. This way, the machine is able to learn all the attributes of the particular image that are relevant to the model. • Unlabelled data • Is quite opposite of labeled data. We feed the machine learning model with raw data and let the model learn the pattern by itself. No human tagging is involved in unlabelled data.

4. If we used the drink example, then the model will evaluate the images based on their characteristics and in this case its shape. After dozens of images being fed into the model, the model should then be able to recognise the difference between those drinks. • There are also hybrid models which combine both supervised and unsupervised machine learning. • After learning the differences between labeled and unlabelled data now arises the question, • "How do we know that our training data is GOOD?"

5. There are two important elements any good training dataset must have: • Relevancy • The data used must be related to the objective of the machine learning model and the items it learns from. You don’t want to use a picture of cars on a highway for your model to learn the differences between various types of drinks. • Focus on the dataset that’s related to your defined criteria. • 2. Consistency • With consistent data, You will likely have a high accuracy model in the testing phase. For example, the label used for specific characteristics is consistent throughout the entire dataset. This can be managed by simple tasks such as making sure the bounding boxes are always tight and the quality of the image is constant.

6. Employing these two methods would ensure high consistency and even higher accuracy. • Garbage in, garbage out • It is very easy and common to find low-quality data for a cheaper price or lesser resources. The question now stands, do you really want to feed this data to your machine learning or AI models, only to get inaccurate and inefficient results? • The world of Artificial Intelligence very strictly follows the “Garbage in, garbage out” notion. That is why you may want to feed your machine only very high-quality data to obtain high accuracy output or result.

7. As of right now, there are lots of Machine Learning datasetsthat you can find online. So in case you want to train your model on specific cases, you might want to search it up online first before you start making your own dataset to save yourself some time. • Sourced from https://www.tictag.io/post/training-data-dataannotation-data-science
