J0nyb0y:


I really appreciate your effort in breaking it down... Thanks for allowing the discussion continue..

Ive been able go grab some cogent and important points from your writeup... From the expert system example you gave, I did a lil more research and found out some other expert systems also...

Which I can also term as knowledge engineering products...I'll begin to look in to them individually so I can be able to identify some of their security challenges and ways the knowledge engineers could have done it better..

On designing a new expert systems for each security challenge might be cumbersome for different of these expert systems and I might begin to go off point from what my supervisor intended... I might just write another kA Stroud

What am thinking is I'll just propose a model of ways of Combating them.

I'll await the results of your research..

Thanks so much.

j0nyb0y,

Below are some links I found. Most of the materials are old. I was not too sure how to get recent information relevant to your context (I was seeing stuffs related to fuzzy-logic/rules). I believe it's just lack of proper vocabulary or the right keyword to check for.

Looking through list of references in paper may be a way to get other relevant materials

1. Knowledge Management: Practices and Challenges

Other links not related to security challenges in Knowledge Based System, but contains discussions about techniques used in KBS are listed below. Even though they are not related to security challenges, you can still extract some useful information that may inform you about security challenges in KBS, or lead you to other materials that can provide such (this is more of researching activity).

1. This document is quite recent (2013), and it talks about apply ant colony optimization knowledge based expert system

Thanks, I'll surely look into these and give you feedback..

You can try one of the following:

1. if you can use python, then I'll suggest you checkout pandas library. I believe it meets the requirements of what you are trying to achieve. Even though I haven't used extensively, I believe it's a mature and easy to use library.
2. check for online converter "csv to sql". (I don't know if such converter exist, but it's worth the try)
3. opening the csv file in excel, save to microsoft access format, and then check if you can convert the data to sql from microsoft access.

thanks would try these options out and get back to you on my success or failure report thanks mate

This is very nice and a bit different from Nairaland. I would not mind being part of this group. Please add me up. I think I will be able to contribute in some way to the progress of the group.

first of all here is what I did based on your suggestions
1. I sent the file to my friend who is good with python to perform your number one instructions still awaiting to hear from him tho

2. I went online and checked for an online converter I found some but it just didn't work probably since there are alot of data on that file am guessing after trying out four different online converters

3. I opened the file as usual in excel and tried saving but just didn't see the format I needed to save to access (.mdb) so I thought what if I can import the csv file from access directly and then I did thanks to MS Access addon tools it worked.

and I have just changed my mind about converting it to sql since I can manipulate the data now externally from my codes to give me what I want

beat regards.

Hello Great minds, from what I've seen here, I hope my question won't sound very foolish. I don't mind anyway.

I am using watson conversation API to buid a bot, but I am having some challenges.
For #A and @B, the bot is to respond "why na"; and for #B and @A, the bot is to say "na so e be".

but my challenge is, for A and B or B and A, the bot responds same "why na". How can I configure the bot to recognise A and B, & B and A in their different orders?

I hope I am clear enough to be understood.

I hail the initiators of this group, I am here to learn.

Sure thing. Thanks for your interest.
We discuss here on Nairaland. The (simple) requirements of the group are on the first page of this post (i.e.first comment on page 0)
Feel free to make contributions by raising discussions about AI related ideas/projects/research or ask questions or answer questions of others.

Thank you.

OK. That's good. Well done.

I remembered you mentioned you are a .NET developer from an earlier comment. I did a quick search for a pandas library equivalent in .NET and the library below was one of the results. Therefore, just in case you want to further pursue using a pandas-like library in .NET, then it may be worth exploring as well.

I haven't used Watson API and I can only contribute very little.

Please for those who have used (or played) with Watson, comment on this.

Even if you haven't used Watson, but have worked on conversational bots where you have "Entity" and "Intent" components, please comment. The Watson API follow similar parttern.

@ruffhandu
A link to wherever we can test what you are working on may be helpful in advising you appropriately.

My contribution
I am not sure how much work or material you have covered before your question, but here's a link to a getting started guide for Watson Conversational (system). If you have already gone through this material before now, then I apologise. If not, I recommend you check it out.

https://console.bluemix.net/docs/services/conversation/getting-started.html#gettingstarted

Additionally, you can also look through the codes of some examples in the link below. It may give you some ideas on how to fix issue(s) in the bot that you are building.

thanks for your effort, would stick with the .mdb format am using now

Am already working on a closed domain question system based on the dataset from sofifa

would share once done with it

Please can anyone explain YOLO algorithm very well?
Just heard of it this month, and apparently it's been around for more than 2 years now.
Cc: lum1 SoftEng Teempakguy and co...

@ruffhandu can we see what you did?
Anyways this link gives a ten minutes brush up of watson api.

Follow and report any anomaly if encountered.

Even though my recent project have been computer vision based (computer vision for video related tasks), I haven't seriously looked into Object Detection Tasks and I haven't read the YOLO paper. Previously, I heard about R-CNN and its variant, but I've been recently reading comments about YOLO recently (I didn't even know it plays in thesame space with R-CNN until your question).

I have been hearing about YOLO in relation to the [url]deeplearning.ai[/url] coursera courses, and I suppose the explanation in this 7mins video should do justice explaining YOLO.

I'm still trying to fully wrap my head around it.
It's performance is just incredible!!!

Hello everyone,

I just stumbled upon Data Science Nigeria 2018 plans. It's really packed with loads to data science goodies and I advise you try participating in one or more events. I really like this initiative, well done to the Data Science Nigeria team. Below is the link

http://www.datasciencenigeria.org/2018plan/


Extra Note
For those who don't know about Data Science Nigeria prior to this post, I apologise. I remember mentioning about the intiative on another AI/ML related thread, but not on this thread prio to this comment.

Later in the day, I will curate a list of other Nigerian/African related AI/ML/Data-Science communities or initiatives for you all to check out.

Thanks.

As mentioned earlier, here's a curation of Nigerian/African/[Black] related AI/ML/DS communities or initiatives.

1. Data Science Nigeria
This is a non-profit run and managed by the Data Scientists Network Foundation. Additionally, they are also throwing academia (especially PhD students) and industry partnership into the mix.

Website: http://www.datasciencenigeria.org/
Twitter: https://twitter.com/DataScienceNIG

In the past, they've organised bootcamps, data science competition on kaggle, and an annual summit.


2. Women In Machine Learning and Data Science (WIMLDS)
This is more of a global initiative, however, there is a Lagos chapter. The aim of the initiative is to support and promote women practicing, studying or interested in the fields machine learning and data science.

Website: [url]http://wimlds.org/[url]
Twitter: [url]https://twitter.com/wimlds[url]
Lagos Chapter Website: https://www.meetup.com/Lagos-Women-in-Machine-Learning-Data-Science/

Lastly, below are links to twitter handles of two co-organisers of the WIMLDS lagos chapter.

3. ForLoopAI
The forloop team travels around Nigeria and Africa hosting talks/meetups to spread more awareness and technical knowledge of software development (mostly web and mobile applications). However, they are currently working on include AI to content of their meet up. Hence ForLoopAI. I guess they will be kickstarting serious AI related talks/meetups in 2018 (this year).

Website: http://forloop.africa/
Twitter: https://twitter.com/forLoopAI

4. AI Saturdays
I just found out about this yesterday. Just like WIMLDS, this is an international intiative. However, they now have a Lagos Chapter. The aim of the initiative is help you become really good at AI via physical training sessions. Therefore, if you more into learning from physical training sessions than online, then you should check them out. The Lagos Chapter will be meeting every saturday from 6th January, 2018 - 21st April, 2018.

Website: https://nurture.ai/ai-saturdays
Twitter (Lagos Chapter): https://twitter.com/AISaturdayLagos

5. Deep Learning Indaba
This is more research oriented and I believe the aim is to span across entire Africa. They focus on increasing African participation and contribution to the advances in artificial intelligence and machine learning, and address issues of diversity in these fields of science. The inaugural event was held in South Africa in September 2017, and they plan to hold it anually.

Website: http://www.deeplearningindaba.com/
Twitter: https://twitter.com/DeepIndaba
Google Group (Mailing List & Discussions): https://groups.google.com/forum/#!forum/mlds-africa

6. Black in AI
This initiative is also an international one and also research oriented. The aim is to provide a space for sharing ideas, fostering collaborations and discussing initiatives to increase the presence of Black people in the field of Artificial Intelligence.

Website: https://blackinai.github.io/
Twitter: https://twitter.com/black_in_ai
Google Group (Discussions): https://groups.google.com/forum/#!forum/black-in-ai
Facebook Group: https://www./250631148730672/?ref=bookmarks


Final Note
If choose do participate in any of above groups please remember to come back and contribute to this Nairaland group here. This group may be the first point of entry to some people interested in Artificial Intelligence (AI), Machine Learning (ML), Data Science (DS) etc.

Thank you.

Wishing you all a HAPPY 2018

Thank you 4kings. I have gone through those, thanks.

@ house, I have to change my approach. I had designed the queries to go in pairs, but it seems the bot doesn't recorgnise order. #A and @B returns the same response as #B and @A.

I have decided to use child nodes, it'll have a 2-step interaction before the final bot response anyway.

Thanks everyone.

I've already registered for AI Saturdays, i saw it on DevCenter Slack group and this is the first time they're organizing in Nigeria.

Anyone interested can register here. *If you stay in Lagos*

Happy new year to everyone!
This is wishing all a blessed and prosperous 2018.

On the fifa dataset:
I did some exploratory data analysis which I love to share.

I have categorized the 'potential' variable on a scale of A(90 - 99) to F(40 - 49) for predictive modeling..., like predicting what is the potential of a player based on the input variables.

Please, comments/contributions will be helpful.

More visualizations.

finally....

Nice work Samcent.

raymod170:


thanks for your effort, would stick with the .mdb format am using now

Am already working on a closed domain question system based on the dataset from sofifa

would share once done with it

I just finished a demo version of the closed domain system take a look

I introduced Speech synthesis to artificially produce human speech as you interact with the software, introduced Part of speech tagging to aid in natural language processing and then my algorithm that processes the data to give desired result.

Would release the software later today

Happy New Year

Analysis on defenders work rate -
Basically this analysis goes to show the level at which fifa assigns a work rate to their game players which is a set and has elements of (High, Medium and low).

All i did was to write an algorithm that groups this elements together as its attached to a particular player and show me which element has the highest number

And from the diagram you can see that a total of 13,560 players has a work rate which falls on the medium element in the set named (work rate) ,2,860 players has a work rate which falls on the high element and 1,574 players has a work rate which falls on the low element

raymod170:
I hope the analysis is self explanatory if not i would also explain

Great work sir. Indeed, I will appreciate an explanation or even a tutorial. I am ready to be mentored. Please which tool/technique did you employ in developing this software? The UI is cool, does one require knowledge of html and/or CSS for such output? Thanks.

raymod170:
I hope the analysis is self explanatory if not i would also explain

bro you good.
Nice work. Like Samcent, I'm ready to be mentored.

Well done raymod170 and Samcent.

Keep up the good work.
