Food Recognition Challenge

🍕 Food Recognition Challenge : Data Exploration & Baseline

So, in this project, we are building a Deep Learning Model which is capable to detect various food using Detectron2, coco, along with other libraries such as Weights & Biases for recording our experimentations, and a bunch of other things

Problem¶

Detecting & Segmenting various kinds of food from an image. For ex. Someone got into new restaurent and get a food that he has never seen, well our DL model is in rescue, so our DL model will help indentifying which food it is from the class our model is being trained on!

Data¶

We will be using data from Food Recognition Challenge - A benchmark for image-based food recognition challange which was launched on March 9, 2020 and ended on May 26, 2020.

https://www.aicrowd.com/challenges/food-recognition-challenge#datasets

We have a total of 24120 RGB images with 2053 validation, all in MS-COCO format and test set for now is same as validation ( debug mode ).

Evaluation¶

The evaluation metrics is IOU aka. Intersection Over Union ( more about that later ).

The actualy metric is computed by averaging over all the precision and recall values for IOU which greater than 0.5.

Setting our Workspace 💼¶

In this section we will be downloading our dataset, unzipping it & downliading detectron2 library and importing all libraries that we will be using

Downloading & Unzipping our Dataset¶

In [ ]:

# Downloading Training Dataset
!wget -q https://datasets.aicrowd.com/default/aicrowd-public-datasets/food-recognition-challenge/v0.4/train-v0.4.tar.gz -O train.zip

# Downloading Validation Dataset
!wget -q https://datasets.aicrowd.com/default/aicrowd-public-datasets/food-recognition-challenge/v0.4/val-v0.4.tar.gz -O val.zip

In [ ]:

# Unzipping Training Dataset
!unzip train.zip > /dev/null

In [ ]:

# Unzipping Validation Dataset
!unzip val.zip > /dev/null

So, the data structure is something like this

│   └───images

└─── val

│   └───images

# Loading pre trained weights
cfg.MODEL.WEIGHTS = model_zoo.get_checkpoint_url("COCO-InstanceSegmentation/mask_rcnn_R_50_FPN_3x.yaml")

Setting up hyperparameters¶

In [ ]:

# No. of Batchs

# No of Interations

# No of Categories(Classes) present

Evaluating the model 🧪¶

After training is done, we will evaluate our model to see how it's performing in the unseen images!

In [ ]:

cfg.MODEL.ROI_HEADS.SCORE_THRESH_TEST = 0.01

cfg.MODEL.WEIGHTS = os.path.join(cfg.OUTPUT_DIR, "model_final.pth")

evaluator = COCOEvaluator("validation_dataset", cfg, False, output_dir=cfg.OUTPUT_DIR)
val_loader = build_detection_test_loader(cfg, "validation_dataset")
valResults = inference_on_dataset(trainer.model, val_loader, evaluator)

Making Submission on AICrowd¶

Step 0 : Fork the baseline to make your own changes to it. Go to settings and make the repo private.

Step 1 : Setting up SSH to login locally to Gitlab

Run ssh-keygen -t ecdsa -b 521
Run cat ~./ssh/id_ecdsa.pub and copy the output
Go to Gitlab SSH Keys and then paste the output inside the key and use whaever title you like.

Step 2: Clone Repo & Add Models & Push Changes

Run git clone git@gitlab.aicrowd.com:[Your Username]/food_recognition_detectron2_baseline.git
Put your model inside the data directioary and then run git-lfs track "data/"
Run git stage . then git commit -m " adding model"
Run git push origin master

Step 3. Create Submission

Go to the repo and then tags and then New Tag.
In the tag name, use submission-v1, ( Everytime you make a new submission, just increase the no. like - submission-v2, submission-v3 )
A new issue will be created with showing the process. Enjoy!

Generate More Data + Some tips & tricks 💡¶

CLoDSA seems a really great choice to generate more dataset. Fortunately there is also a really cool colab notebook on how to generate more dataset using CLoDSA

There is also an ongoing youtube series series from Immersive Limit on how to generate more dataset using blender ! Blender for AI Devs

And also this --
