What are bi-directional attention networks? And their applications...


Please, I need some explanations and articles on topic.


Thanks...
Attention or neural networks?

Please bro
Am seeing so many videos on YouTube
Please which person's video can u recommend for me that will be easy for jjc like me

What type of videos are you talking about? Excel or what..? If you go through this thread from the beginning I'm sure you would gain a lot of insight and as well some relevant links or videos suitable for your trips. Kindly find time to check this thread bro.

Start with excel.. Up to advance level ( functions , formula, slicers, chart, pivot tables, vlookups, power query etc

I think attention networks are the main component of transformer architecture models used in nlp tasks such as text generation, question/answering systems.
You could check google for "BERT" or "XLNET" or preferably the "transformer architecture".

P.s:this doesn't really answer your question completely but I just thought to point you in a particular direction.

Check "Excel is fun" by mike on youtube.

He has a series called MSTPDA.

Thats a complete thread for data analysis in excel.

Its a long series but worth the length.

I wish you stay near by Ajeromi Apapa, I would just send them to you from my my machine.


Good luck.

When you get stuck, google answer or reach out to me on my signature.

Not just for Excel alone but for Power Bi as well, dude is an analysis wizard.
In case you’re around Badagry, I have his Power Bi and Excel video tutorials.
hello bro. are you still in badagry?

Good morning,
I have learnt SQL and Tableau even SSIS but i'm a little bit confused as to how to practice and perfect those skills.
I want to make sure that i'm good at them before learning python for data science.
Please what should i do to perfect these skills.
thanks

Not data base... U know when dealing with real data u have to be careful, a professional in SQL will tell never to import data directly.. you Know data analysis/ science is an art u can do many things to achieve same results.
Although I started with PostgrSQL then moved to mysql, I later realised I can be more flexible in Microsoft SQl than the rest. Although there are different ways to convert data, after importing them u can create a new table and copy the data into the new table. Have created a store procedures on my MSQl just to convert any data within 5 minutes.
I was using visual studio shell before but all the process has been added to the lastest Msql version, but using VSS for ETL is still cool cause within it u can do some data clearing, removing NaN values, or unnecessary column and doing some adjustments.

good day boss. please can we meet at sango. really need those tutorials

It's still possible, yes. The most important thing is to have a first degree. Now you can overcome this shortcoming of not having a degree in these aforementioned disciplines by showing some impressive projects, certificates that you've been able to accomplish with the language(s) or tools in question (Python, MySQL etc)

How can one build portfolio in data science?

I want to perform multiple image processing using opencv in jupyter notebook. I tried to upload the datasets (images) that's stored in my desktop using this code:

import os
import numpy as np
import cv2

img = cv2.imread('/User/victor/Desktop/data/mask/facemask.jpg', 0)
img



import os
import numpy as np
import cv2

resize_width = 100
resize_height = 100
path = '/User/victor/Desktop/data/mask/facemask
images = [] # List to append the images as 2D numpy arrays.
target = [] # List to append the target
originalrepo = [] # Create a repo for flattened pixels

for root, dirs, files in os.walk(path):
for file in files:
with open(os.path.join(root, file), "r"wink as auto:
img = cv2.imread(root+'/'+file, 0)
img = cv2.resize(img, (resize_width, resize_height))
images.append(img)
# Append the flattened image to the pixel repo
originalrepo.append(img.flatten())
# Append the folder where the image is to the target list
target.append(root.replace(path,'').replace('/',''))
# Convert the repo list into numpy array
originalrepo = np.array(originalrepo)
print(originalrepo)
print(target)

I got this error :"opencv(4.5.1)/private/var/folders/nz/vv4_9tw56nv9kvyaszvwg80000gn/T/pip-req-build-39p1qqfs/opencv/modules/imgproc/src/resize.cpp:4051: error: (-215:Assertion failed) !seize. Empty() in function 'resize'

Please I'm appealing for assistance, if there's another simpler code I could use or if I made any error.
Note that I opened the jupyter notebook in the same folder that the dataset are located.

try using os.path.join in the cv2.imread() method instead of concatenating the root and file,and also is there really a need for the "with" statement because you didn't use it?
