How do you improve precision and recall?

If you want to maximize recall, set the threshold below 0.5 i.e., somewhere around 0.2. For example, greater than 0.3 is an apple, 0.1 is not an apple. This will increase the recall of the system. For precision, the threshold can be set to a much higher value, such as 0.6 or 0.7.

Does more data increase accuracy?

One last thing to note is that more data will almost always increase the accuracy of a model. However, that does not necessarily mean that spending resources to increase the training dataset size is the best way to affect the model’s predictive performance.

How can validation loss be reduced?

Solutions to this are to decrease your network size, or to increase dropout. For example you could try dropout of 0.5 and so on. If your training/validation loss are about equal then your model is underfitting. Increase the size of your model (either number of layers or the raw number of neurons per layer)

Why is more data better?

More Data = More Features

The first and perhaps most obvious way in which more data delivers better results in data science is the ability to expose more features to feed your data, science models. In this case, accessing and using more data assets can lead to “wider datasets” containing more variables.

What is accuracy formula?

To estimate the accuracy of a test, we should calculate the proportion of true positive and true negative in all evaluated cases. Mathematically, this can be stated as: Accuracy = TP + TN TP + TN + FP + FN. Sensitivity: The sensitivity of a test is its ability to determine the patient cases correctly.

What makes a measurement precise?

Precision refers to the closeness of two or more measurements to each other. Using the example above, if you weigh a given substance five times, and get 3.2 kg each time, then your measurement is very precise. Precision is independent of accuracy. You can be very precise but inaccurate, as described above.

Can we increase both precision and recall?

As we increase precision, we decrease recall and vice-versa. Precision is the number of true positives divided by the number of true positives plus the number of false positives.
