Create new dataframe that contain the average value from some of the columns in the old dataframe

Asked 2022-Mar-11 at 05:00

I have a dataframe extracted from a csv file. I want to iterate a data process where only some of the columns's data is the mean of n rows, while the rest of the columns is the first row for each iteration.

For example, the data extracted from the csv consisted of 100 rows and 6 columns. I have a variable n_AVE = 6, which tells the code to average the data per 6 rows.

ANSWER

Answered 2022-Mar-11 at 05:00

You can group the dataframe by the grouper np.arange(len(df)) // 6 which groups the dataframe every six rows, then aggregate the columns using the desired aggregation functions to get the result, optionally reindex along axis=1 to reorder the columns

To generate a csv file where each column is a data of sine wave of frequency 1 Hz, 2 Hz, 3Hz, 4Hz, 5Hz, 6Hz and 7 Hz. The amplitude is one volt. There should be 100 points in one cycle and thus 700 points in seven waves.

Using TFDS datasets with Keras Functional API

Asked 2022-Mar-02 at 20:05

I'm trying to train a neural network made with the Keras Functional API with one of the default TFDS Datasets, but I keep getting dataset related errors.

The idea is doing a model for object detection, but for the first draft I was trying to do just plain image classification (img, label). The input would be (256x256x3) images. The input layer is as follows:

ANSWER

Answered 2022-Mar-02 at 07:54

I think the problem is that each image can belong to multiple classes, so I would recommend one-hot encoding the labels. It should then work. Here is an example:

ANSWER

Answered 2021-Nov-16 at 18:02

The duplication issue comes from the fact that you are reading two files in a nested way, once a line from the test.txt is read, you open the location.txt file for reading and process it. Then, you read the second line from test.txt, and re-open the location.txt and process it again.

Instead, get all the necessary data from the location.txt, say, into a dictionary, and then use it while reading the test.txt:

How to split pascal case address in SnowFlake?

Asked 2021-Oct-03 at 22:38

In order to create PlaceKey for addresses to link some of my tables, I need to split an address column in SnowFlake.

I am not familiar with JavaScript, but I tried Javascript UDF in SnowFlake. Then I don't know how to deal with the addresses like '123_45ThSt'.

The output of my function is like '123_45 Th St'. I am stuck here.

The expected output is '123 45Th St'. Hope someone could help me out. Much appreciated!
