Finding the best model and parameters for a model to your problem in machine learning is important. There is a technique Hyperparamter Tuning to help to find best parameters for model.
However, Finding the best model and tuning the model manually is a tedious and time consuming works, thus it…
Having a robust working environment can help you a lot along your way in machine learning or even in programming.
In the part7, we know that we have to preprocess data before training our model. We will define a function for loading dataset and do the following.
Prepare and preprocessing dataset is a big section. We can’t just feed raw data we have into machine learning model and then tell it to learn patterns from the data. Instead, we must prepare and preprocessing raw data before feed it to our model in order to train our model.
We have applied NLP to sommeliers description for each wine in part 5 .
Now we can find out frequency of words for a wine, for a grape and in all descriptions. Here we are going to visualise the frequency of words.
We will use winemag-data-130k-v2.csv …
After part 4, we now need to analyse the descriptions that was given by sommeliers. Sommeliers comprise words into sentence and sentences into paragraphs. We can try to find out what words had been used mostly in descriptions and for particular wine and for variety(grape). …
I have done data analysis on points and price in dataset from part 3 . Now I am going to look into country, winery and grape (variety).
We will use winemag-data-130k-v2.csv dataset for machine learning.
EDA (Exploratory Data Analysis)
Exploring the dataset that we have in our hand is important step in machine learning because it help me understand dataset. Machine Learning is also involved Data Science.
I can use Pandas and Matplotlib to assist me to understand dataset much better.
I am now focusing…
Select a particular data and viewing data is easy.
Here I use CSV for examples.
To see DataFrame, we can just load csv file and Pandas will turn it into a DataFrame
car_sale_df = pd.read_csv('drive/MyDrive/Colab Notebooks/Data/Data-Analysis-With-Pandas/car-sales.csv')car_sale_df
In this part of Wine Review journey, I am going to download dataset from Kaggle and start to clean dataset and fill missing values.
I am inspecting dataset and try to find out detail information about the dataset and then base on the information I gain from dataset inspection, I…
