Reality of Practical Impletation of ML Projects

After completing two initial ML courses, which I did reasonably comfortably, I wanted to make a very basic project my self based on what I learnt. I experienced that there are a number of problems like set up data, enviroment creation etc is required to be solved, which are readily available for exercises to be completed in such tutorials which I comleted. So it is utmost important to be able to create basic set up and environment creation other than data preparation for the project you are working on. Data preparation is making digital representation of your project in Numpy. If you are building an image compression project, you have to convert your png or jpg image into matrix of intensities of pixels etc. and than converting them in to required formats. Some of the imported libraries do not work at all as I am unable to run run_kMeans() So I am stuck up here and decided to first practice those small things before attempting to take on the third course. I am enjoying the course content. I feel I will enjoy more if I practice the basics to get more clearer ideas about what's happening under the hood. I quote Prof Andrew Ng "It is completely fine to start small, and use that to learn and continue to grow! " I am taking a break for 15-20 days for my neurological checkup in hospital. Then I will get back to the ML and share my learning experience. Until next week BYE! I am back from my medical follow up. I have since completed third course of ML that covers unsupervised leaning anomaly detection, Reinforced learning including moon lander project. It sounds some thing great. Course material is good but for lab work solutions were almost available, human being tend to follow path of least resistance and I was also not exceptional. Though the basics are clear but implementation and data preparation part which is about 80% of the lab was readily available, which otherwise could have required you to take up advanced skill in data visualization, data preparation apart from getting expertise in numpy, tensor flow, pandas etc., how ever it was a good course to peep into. Now as I started from data science and python course, I will get back to that field once I quench my curiosity related to Django web development.

बंजारानामा / नज़ीर अकबराबादी

I liked a snippet from "BANJARANAMA" by Nazir (written way back in late 18th century) this week and wanted to share it with you. In a simple way he describes the futility of worldly material gain . I believe many of us have an untold story, sweet or bitter, sharing gives comfort and joy. (टुक हिर्सो-हवस= लालच, क़ज़्ज़ाक़ = डाकू, अजल= मौत, शुतर= ऊंट) टुक हिर्सो-हवस को छोड़ मियां, मत देस विदेश फिरे मारा। क़ज़्ज़ाक़ अजल का लूटे है, दिन रात बजाकर नक़्क़ारा। क्या बधिया, भैंसा, बैल, शुतर क्या गोने पल्ला सर भारा। क्या गेहूं, चावल, मोंठ, मटर, क्या आग, धुंआ और अंगारा। सब ठाठ पड़ा रह जावेगा, जब लाद चलेगा बंजारा॥1॥ गर तू है लक्खी बंजारा और खेप भी तेरी भारी है। ऐ ग़ाफ़िल, तुझ से भी चढ़ता एक और बड़ा व्यापारी है। क्या शक्कर, मिश्री, क़ंद, गरी, क्या सांभर मीठा खारी है। क्या दाख, मुनक़्क़ा सोंठ, मिरच, क्या केसर, लौंग, सुपारी है। सब ठाठ पड़ा रह जावेगा, जब लाद चलेगा बंजारा॥2॥ तू बधिया लादे बैल भरे, जो पूरब पश्चिम जावेगा। या सूद बढ़ाकर लावेगा, या टोटा घाटा पावेगा। क़ज़्ज़ाक अजल का रस्ते में जब भाला मार गिरावेगा। धन, दौलत, नाती पोता क्या, एक कुनबा काम न आवेगा। सब ठाठ पड़ा रह जावेगा, जब लाद चलेगा बंजारा॥3॥ हर मंजिल में अब साथ तेरे यह जितना डेरा डंडा है। ज़र दाम दिरम का भांडा है, बन्दूक सिपर और खाँड़ा है। जब नायक तन का निकल गया, जो मुल्कों मुल्कों हांडा है। फिर हांडा है न भांडा है, न हलवा है न मांडा है। सब ठाठ पड़ा रह जावेगा, जब लाद चलेगा बंजारा॥4॥ जब चलते-चलते रस्ते में यह गौन तेरी ढल जावेगी। एक बधिया तेरी मिट्टी पर, फिर घास न चरने आवेगी। यह खेप जो तूने लादी है, सब हिस्सों में बंट जावेगी। धी, पूत, जमाई, बेटा क्या, बंजारिन पास न आवेगी। सब ठाठ पड़ा रह जावेगा, जब लाद चलेगा बंजारा॥5॥ यह खेप भरे जो जाता है, यह खेप मियां मत गिन अपनी। अब कोई घड़ी, पल साअत में, यह खेप बदन की है कफ़नी। क्या थाल कटोरे चांदी के, क्या पीतल की डिबिया ढकनी। क्या बरतन सोने चांदी के, क्या मिट्टी की हंडिया चपनी। सब ठाठ पड़ा रह जावेगा, जब लाद चलेगा बंजारा॥6॥

Neural network

After completing my Supervised Machine Learning: Regression and Classification I am now starting Neural Network from this week. I will try to make my personal notes on this site. I want to share the fact that, while taking up the course I realized that the mental agility and memory is reduced drastically. You can measure your ability when you are challenged. Working in public utility company in comfort of my office rendered me worthless. I have now found a new purpose of living but a bit late, I am at present in my late sixties. How ever I target to complete all the three courses of Prof Andrew Young including deep learning through coursera plateform. Earlier I completed part of the syllabus working with Octave (A kind similar to MatLab) which let me concentrate fully on the Machine Learning with less stress on coding, but later I found that Python is a must as mostly all practical problem is dealt using Python more over Python has great tools for data analysis like Pandas, Numpy, Mtplotlib, Scikit-learn etc. This led me to take up a course on Python (Python For Every body by Charles Severlence) and a youtube course of Corey Schafer on Python and Django. It induced in me a fresh interest towards Python including web scraping using RE tools. Let me see how far can I complete neural network. 29-8-2022 I could complete another 4 week course on advanced algorithm on neural network. I sincerely admit that completing the course is only knowing how much we do not know about the depth of this strange world. Practicing on the machine learning is abstracting the unimaginable capacity of the computer and put them to service of mankind in different sphere of knowledge. See you next week

TINKANANA

I am sure if you are reading this post you must be puzzled with the title of this strange looking word. But for some it reminds of great treasure of love and affection. The word gets its true meaning how they are applied. Tinkanana was a lean and thin personality in his seventies when he was naturally adored by this title by cute looking group of children just learned to walk and speak. Its a different story that those little ones are now standing tall in their respective fields in new world full of challenges. Back to the story of Tinkanana, for some he was grandfather, for some he was affectionate loving father. Coming from an old village in Narayanganj (Now in Bangladesh, at that time undivided India ) way back in 1920 a flamboyant kid of 10 years full of energy with nothing to loose, playing in open ground of the village, swimming in the ponds, riding on back of buffaloes, some times jumping down to the river from a branch of the tree leaning to wards the inflating river at its bank, at times fled away from home and coming back with a wide smile on his face. This kid while enjoying life to its full also completed schooling and came through with flying colors in math's from Sonergaon GR Institute Dacca, Bengal Academy Anglo-Vernacular High School. I wonder how a village educated boy could have developed such a professionally high writing skill, I still have an old letter, the handwriting speaks so much about the education of old time. Continuing his journey in life destiny brought him to Rangoon, where Tinkanana's father Bhuvan Mohan Chowdhury was posted as station master( You may be wondering how come there came railway line in 1928 yes it was there in British India ). He completed his Civil Engineering Diploma Course from Government Technical Institute Insein, Government of Burma. When I think of it how they could have gathered courage and confidence to move to a far off place to get education from an unknown far off village to a renowned city. Then there came the ill-fated shadow of war during war time 1941-42 he was posted in Burma PWD. It was a hard time to work in aerodrome and work day and night to facilitate landing and taking off fighter planes. The army has to retreat, with that came the great journey to save life with two kids and family. We at this age can not even think of hardship and trauma of war time. Escaping from Burma to India was not easy involved land forest and part of journey on streamer in engulfing waves of Bay of Bengal. It was a miracle that Tinkanana and family survived this journey of life and death and securely bringing back not only his family, and all dependents solely securely to the land mass of main land India. Here it was a new challenge to feed a large group of family with cousins in-laws. Tinkanana being the eldest and ablest naturally took the new challenge. It rarely seen in this new social setup of all the convenience, the culture of joint family, joint responsibility and helping out looking after all equally. It was a span of about 4-10 years that took Tinkanas family to settle down. It must be 1948 family came to Akaltara then to Bilaspur and settled down there. He got posted as overseer in MP PWD. The family was now secure and could hope and work hard to get to a promising future. The journey of Tinkanana was a journey of fighting to the end, as he started as a kid with a thought of losing nothing, I think the root of all the great achievements lies in this mentality throw your self as there is nothing to loose and come up with treasure if the almighty wishes so. After all in this age of abundance and knowledge the inquisitive instinct of man kind have lead us to install James Webb Space telescope to see deep in to unknown past, I find similarity to its journey with that of Tinkanan. He is no more with us but the memory of his courage, devotion and do-or-die spirit will continue to inspire us all.
