What is Coco in machine learning?
Common Objects in Context (COCO) is a database that aims to enable future research for object detection, instance segmentation, image captioning, and person keypoints localization
How do I train a python model?
Train/Test is a method to measure the accuracy of your model It is called Train/Test because you split the the data set into two sets: a training set and a testing set 80% for training, and 20% for testing You train the model using the training set
How do you split data into train and test in Python?
The process is pretty much the same as with the previous example:
- Import the classes you need
- Create model instances using these classes
- Fit the model instances with fit() using the training set
- Evaluate the model with score() using the test set
How do you become a deep learning model?
Deep learning models are built using neural networks A neural network takes in inputs, which are then processed in hidden layers using weights that are adjusted during training Then the model spits out a prediction The weights are adjusted to find patterns in order to make better predictions
How do I learn Scikit learn?

Should I learn Scikit learn or TensorFlow?
TensorFlow really shines if we want to implement deep learning algorithms, since it allows us to take advantage of GPUs for more efficient training Tensorflow is mainly used for deep learning while Scikit-Learn is used for machine learning
Why Sklearn is used in Python?
Scikit-learn is probably the most useful library for machine learning in Python The sklearn library contains a lot of efficient tools for machine learning and statistical modeling including classification, regression, clustering and dimensionality reduction
What method does Scikit learn to find the best classification hypothesis for the training data?
In scikit-learn, an estimator for classification is a Python object that implements the methods fit(X, y) and predict(T) An example of an estimator is the class sklearn svm SVC , which implements support vector classification
What is fit () in Python?
The fit() method takes the training data as arguments, which can be one array in the case of unsupervised learning, or two arrays in the case of supervised learning Note that the model is fitted using X and y , but the object holds no reference to X and y
What is supervised and unsupervised learning?
In a supervised learning model, the algorithm learns on a labeled dataset, providing an answer key that the algorithm can use to evaluate its accuracy on training data An unsupervised model, in contrast, provides unlabeled data that the algorithm tries to make sense of by extracting features and patterns on its own
Why linear regression is not suitable for classification?
This article explains why logistic regression performs better than linear regression for classification problems, and 2 reasons why linear regression is not suitable: the predicted value is continuous, not probabilistic sensitive to imbalance data when using linear regression for classification
Why would a linear regression model be appropriate?
Simple linear regression is appropriate when the following conditions are satisfied The dependent variable Y has a linear relationship to the independent variable X To check this, make sure that the XY scatterplot is linear and that the residual plot shows a random pattern (Don’t worry
Why logistic regression is better than linear regression?
Linear regression is used to predict the continuous dependent variable using a given set of independent variables Logistic Regression is used to predict the categorical dependent variable using a given set of independent variables Logistic regression is used for solving Classification problems
Can you use linear regression categorical data?
Categorical variables can absolutely used in a linear regression model In linear regression the independent variables can be categorical and/or continuous But, when you fit the model if you have more than two category in the categorical independent variable make sure you are creating dummy variables
How do you convert categorical data to numeric?
Below are the methods to convert a categorical (string) input to numerical nature:
- Label Encoder: It is used to transform non-numerical labels to numerical labels (or nominal categorical variables)
- Convert numeric bins to number: Let’s say, bins of a continuous variable are available in the data set (shown below)
Which regression model is best?
Statistical Methods for Finding the Best Regression Model
- Adjusted R-squared and Predicted R-squared: Generally, you choose the models that have higher adjusted and predicted R-squared values
- P-values for the predictors: In regression, low p-values indicate terms that are statistically significant
How do you tell if a regression model is a good fit?
Lower values of RMSE indicate better fit RMSE is a good measure of how accurately the model predicts the response, and it is the most important criterion for fit if the main purpose of the model is prediction The best measure of model fit depends on the researcher’s objectives, and more than one are often useful
What is the best fit model?
Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points Statisticians typically use the least squares method to arrive at the geometric equation for the line, either though manual calculations or regression analysis software
How do you know if a regression model is good?
The best fit line is the one that minimises sum of squared differences between actual and estimated results Taking average of minimum sum of squared difference is known as Mean Squared Error (MSE) Smaller the value, better the regression model
