Met een simpele tik kunt u het licht aan of uitzetten en de helderheid aanpassen zonder dat u fysieke knoppen hoeft te gebruiken. Dit moderne ontwerp zorgt voor een opgeruimde werkplek en biedt een soepele, intutieve ervaring, waardoor het ideaal is voor omgevingen met weinig licht waar

KENMERKEN

AANRAAKGEVOELIGE SCHAKELAAR – De bureaulamp heeft een strakke, aanraakgevoelige schakelaar, waardoor je hem makkelijk met één druk op de knop kunt bedienen. Met een simpele tik kunt u het licht aan- of uitzetten en de helderheid aanpassen zonder dat u fysieke knoppen hoeft te gebruiken. Dit moderne ontwerp zorgt voor een opgeruimde werkplek en biedt een soepele, intuïtieve ervaring, waardoor het ideaal is voor omgevingen met weinig licht waar snelle, handsfree bediening essentieel is.

DRIE VERLICHTINGSMODI – De instelbare helderheid biedt drie verlichtingsmodi om aan uw behoeften te voldoen. De lamp biedt oogvriendelijke verlichting, vrij van schadelijk blauw licht en flikkeringen, waardoor vermoeidheid en overbelasting van de ogen worden verminderd. Of u nu fel licht nodig hebt om geconcentreerd te kunnen werken of zacht licht om te ontspannen, deze bureaulamp is perfect voor lange lees- of studiesessies.

DRAAIBARE CONSTRUCTIE – Dankzij de flexibele, draaibare lampkop kunt u de verlichtingshoek aanpassen aan uw specifieke behoeften. Of u nu aan het werk bent, aan het lezen bent of aan het ontspannen bent, u kunt het licht precies richten waar het nodig is, voor maximaal comfort en gemak bij elke taak of stemming.

DUBBELE STROOMVOORZIENING – Kies tussen twee handige stroombronnen: sluit de lamp rechtstreeks aan op een standaard stopcontact voor constante stroomvoorziening, of sluit hem aan op een laptop of powerbank om hem op te laden. De ingebouwde oplaadbare batterij biedt langdurige prestaties, zodat u kunt genieten van betrouwbaar, ononderbroken licht, of u nu thuis, op kantoor of onderweg werkt.

AFNEEMBARE MAGNETISCHE FUNCTIE – Verwijder de lampkop eenvoudig van de magnetische kogelkop op de standaard om hem te gebruiken als draagbare wandlamp of draagbare noodlamp. De magnetische kogelkop bevestigt de lamp stevig aan de standaard, waardoor hij gemakkelijk kan worden verwijderd en flexibel is. Bovendien is de lamp voorzien van antislipkussentjes voor extra stabiliteit, zodat hij stevig op zijn plaats blijft staan. Deze functie maakt de lamp ideaal voor zowel gebruik op een bureau als draagbare lichtbron in noodgevallen.

Excellent book on ML
Format: Paperback
This is a great book on machine learning. Topics covered are extensive - from beginner level to advanced topics including math behind different algorithms. However, not "all" algorithms are covered. Please go through the table of contents. The first part - 11 chapters - covers machine learning concepts and second part covers advanced topics with Pytorch. There are lots of excellent code and they work!! The quality of the book I received is excellent. I have gone through all 742 pages, and it has held up very well!! I used Jupyter notebook to run all examples. I created a new notebook and copied and pasted the code and ran them. This approach worked very well for me. At the same time, I could experiment with my take on the code snippets and definitely added to my knowledge. Only issue I have is on the second part of the book discussing PyTorch: (1) Some packages are a bit older version: e.g., transformer 4.9.1 whereas current version is 4.48+. It took some tweaking/recoding to get the examples working. (2) There is not much discussion on why certain architecture was chosen - e.g., number of layers, is there a rule of thumb on how to improve performance by changing these parameters? Even with CUDA the code run for a long time. Therefore, experimenting with different values of parameters become too time consuming. (3) On the same note, if I can achieve test accuracy of 90%+ using logistic regression and almost the same (perhaps one or two percent better with PyTorch with IMDB movie review dataset and that two much faster why should I use PyTorch for this dataset? Obviously, PyTorch is for certain types of problems. Discussions can be included by not adding to the exhaustive (and apt) contents. Personally I was disappointed by lack of any example on time series. Must have for ML practitioner as a reference and guide.

Excellent Textbook for Hands-On Learning of ML
Format: Kindle
This textbook is for the serious life-long learners of machine learning. There are at least two ways to ‘consume’ this book. For the expert in ML, this is a textbook to study as a clear comprehensive ML overview and then to dive into sections of interest or ignorance. The concepts are grounded in code examples and are well cited (with links) to sources. Further, this textbook is appropriate if you are TensorFlow-centric and want to broaden into cutting-edge ML models/tools coded in PyTorch. For a new learner to ML, this is a textbook to DO (not just READ) with hands-on and brain-engaged. If you realize that ML is a key life-long skill for your career, consider this textbook as part of a daily learning habit (10-30 min). From personal experience, my advice to the new learner is as follows… First, clone the GitHub repository, setup your Python environment, and study the textbook, while working through the notebooks. Go on tangents and break the code. Do this methodically as part of your daily learning habit, but do not hesitate to jump ahead several chapters to prepare for tomorrow’s meeting. There is enough excellent material here for a full year of ML adventures. I did a similar strategy with Raschka’s first textbook. About four years ago, I had finished Andrew Ng’s Deep Learning Specialization as a student in his first cohort. I knew the concepts well but could not do the actual application coding. I was surprised how my Python coding improved by following Raschka’s clean and elegant style. And Raschka’s code examples were meaty enough to be springboards into working applications. Several textbook editions later, what is different about this new edition? First, it moves you through scikit-Learn (a firm foundation) to PyTorch, instead of TensorFlow. PyTorch is a better stepping-stone, both conceptually and practically. With PyTorch, you will go further with less energy, while being able to convert your efforts into TensorFlow as needed. In addition, most of the cutting-edge ML/AI/DL research is in PyTorch. It is nice to read a recent arXiv paper, clone their repository, click on the Colab tutorial, and replicate their experiments, along with picking up a ton of new coding tricks & tips. I am excited to work through these PyTorch sections to hone my skills. Second, there is a clear recognition of model tracking and tuning practices. This is often a gap in other ML textbooks and courses. Once you progress beyond the simple demo examples in a lecture, you realize that the real work is experiments, more experiments, and still more experiments, so that you must understand what the model architecture and hyperparameters are doing to your dataset. There is good coverage of scikit-Learn pipeline, grid search, model performance, and the like. Third, ML/AI/DL practice is rapidly evolving. Every week new ML packages/services become available that could save much grief on your current project. What is refreshing about Raschka’s textbook series is that he constantly adding cutting-edge topics because he likes to stay current and to help us stay current. Hence, this edition contains recent ML treats as: transformers, self-supervised learning, autoencoders-to-GAN, graph neural networks, DBSCAN, t-SNE (with brief mention of UMAP), and PyTorch-Lightning.
