一、TensorFlow + Android (dataset: Mnist)

We used TensorFlow to define and train our machine learning model, which can recognize handwritten numbers, called a number classifier model in machine learning terminology.

We transform the trained TensorFlow model into TensorFlow Lite ready for deployment.

Train machine learning models

Run and get Model file named mnist.tflite.

Android application

https://github.com/tensorflow/examples/archive/master.zip

Import it in Android and put the model file in folder named assets.

三、Ideological Practice

Research on the "trinity" protection of cultivated land quantity, quality and ecology

1. Data collection (cases, pictures, data) 
2. Research design (feasibility analysis) 
3. Research results (Report: Data summary) -
4. Discussion and analysis (case analysis, feasibility suggestions) 

四、How do I check battery health on a Dell laptop

如何在戴尔笔记本电脑上检查电池运行状况 | Dell 中国

1. Check battery health in the BIOS

Turn on your computer and press the F2 key when the Dell logo screen appears

2. Check battery health in the diagnostics

Power on your computer and press the F12 key when the Dell logo screen appears.

In the one-time startup menu, select Diagnostics, and then press Enter.
Respond appropriately to user prompts in the prestartup diagnostics.
View the battery test results.

Result Code:2000-0000
