First into the research pits, the basic concepts do not understand, in order to some of the necessary simple knowledge to add a memory, finishing this article, when it is a dictionary, ready to forget at any time to check. Referring to the explanations of some great gods, the knowledge points to be summarized today are some criteria for judging the results of the search, including: Accuracy rate (Precision rate), recall (

context is about 450 characters, and the average length of the answer is approximately 80 characters. The script that produces the dataset can also generate a test dataset (see the following figure). In the test dataset, each record includes: a context, 1 true answers, and 9 wrong answers. The goal of this model is to have the highest score for a true answer and a low score for the wrong answer (so that the model can pick the right answer.) ） Introduction of the data set, roughly speaking of th

This article introduces the content of the detailed classification evaluation indicators and regression evaluation indicators and Python code implementation, has a certain reference value, now share to everyone, there is a need for friends to refer to. 1. Concept Performance measurement (evaluation) indicators, the main divided into two major categories:1) Classification Evaluation Index (classification), main analysis, discrete, integer. Specific indicators include accuracy (accuracy rate), pre

controlled by the Raspberry Pi Gpio. Initially wanted to use GoPro as a video capture device, but looked up a lot of information also tried various methods found temporarily unable to achieve (if any, please leave a message to tell me:), so changed a cheap webcam.GoPro can pass the image to the phone or pad in real time via WiFi, which is not transmitted to the Raspberry Pi.(2) to write the gimbal control algorithmAccording to the characteristics of

Raspberry Pi Gpio controls the gimbal tilt and horizontal rotation. I began to want to use GoPro as a video collection device, but looked at a lot of information and tried various methods to find the temporary impossible to achieve (if there is a message please tell me:). So I switched to a cheap webcam.GoPro can pass the image to the phone or pad in real time via WiFi. Just can't pass it to the Raspberry Pi.(2) to write the gimbal control algorithmT
