Method calculate accuracy

[NathanFirmo]

🗒️ Context

Add a method to calculate algorithm accuracy based on a datase.

Example

[
  {
    "sentence": "im feeling quite sad and sorry for myself but ill snap out of it soon",
    "category": "sadness"
  },
  {
    "sentence": "i feel like i am still looking at a blank canvas blank pieces of paper",
    "category": "sadness"
  },
  {
    "sentence": "i feel like a faithful servant",
    "category": "love"
  },
  {
    "sentence": "i am just feeling cranky and blue",
    "category": "anger"
  },
  {
    "sentence": "i can have for a treat or if i am feeling festive",
    "category": "joy"
  },
  {
    "sentence": "i start to feel more appreciative of what god has done for me",
    "category": "joy"
  },
]

Behaviour

The classifier will automatically split dataset into train and validation data and will calculate its own accuracy.
